Engine And Engine Cooling Problems of Hyundai Palisade - part 1

My vehicle is experiencing sudden, unprovoked engine stalling specifically during turns [specify: e. G. , when turning right from a complete stop / while coasting through a left turn at 15 mph]. When the engine stalls mid-turn, the vehicle immediately loses all power steering and braking assist. This creates an incredibly dangerous situation where the vehicle becomes nearly impossible to steer or stop, placing myself, my passengers, and other drivers at imminent risk of a catastrophic collision. The vehicle experienced a stall while executing the sharp right turn onto the [xxx] exit. . Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Our 2026 Hyundai Palisade has experienced repeated dangerous electrical failures while driving. Xxx all instrument displays went completely black while driving. The engine continued running. Gateway Hyundai in fargo, nd, checked the vehicle but verbally reported finding no diagnostic codes. Xxx while driving on the highway at night, the interior displays and exterior lights repeatedly flickered off and on. Xxx the vehicle unexpectedly lost power and shut down at highway speed, requiring a tow to don bessette Hyundai in [xxx]. The dealership documented 36 stored diagnostic trouble codes, primarily communication faults. The codes were cleared, and an ecm software update was performed. No confirmed cause was identified. Xxx the instrument panel went completely black twice while driving, lasting approximately 10 minutes and 14 minutes. Xxx while driving at night, the interior and exterior lights again flickered off and on. Approximately 30 minutes later, the instrument panel went black and the exterior lights dimmed. We pulled over, activated the hazard lights, and restarted the vehicle, but normal lighting did not return. We drove approximately 14 miles with hazard lights on to reach the nearest town. The lights eventually returned, but the instrument panel continued flickering, the front camera repeatedly reported being disabled, and driver-attention warnings appeared during the drive home. These failures continued after dealership service and a software update. We are concerned about another sudden loss of engine power, headlights, or critical driver information at highway speeds. These failures pose a serious safety risk to occupants and other motorists. We request that NHTSA investigate these electrical failures. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The engine misfires and runs very rough when stopped in drive after highway driving, and the vehicle hesitates and struggles to accelerate from a stop. At about 3,000 miles, phil long, colorado springs diagnosed a failing cylinder 6 fuel injector and replaced it on 22 April 2025. The problem continues after that repair. The condition repeats in the same way. After 15 minutes to 1 hour of interstate driving, I exit the highway. When I stop at the first traffic light on the off ramp, the engine begins idling very rough, and the tachometer shows about 500 rpm. When I shift to park, the idle smooths out. When I shift back to drive, it becomes very rough again. Pulling away from the light is difficult because the vehicle hesitates and does not accelerate normally. This has happened three times since the repair, most recently on [xxx] at about 5,800 miles. The check engine light did not come on. Conditions: 80 f, clear weather. [xxx] exit [xxx]. This is a safety concern because the vehicle may not accelerate when I pull into an intersection or merge into traffic. Other 2026 Palisade owners have reported similar misfires and hesitation, and Hyundai issued TSB 26-01-068h (service campaign 9d6) for engine misfires on 2026 Palisade 3. 5l vehicles. I have asked Hyundai to confirm whether this campaign has been performed on my vehicle. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My 2020 Hyundai Palisade (3. 8l v6) suffered an engine failure at approximately 108,000 miles. On September 3rd,2026 , while driving at about 65 mph, the engine began knocking loudly. There was no warning before this happened and the engine light had not come on. The vehicle was taken to shottenkirk Hyundai, an authorized Hyundai dealer, which diagnosed a connecting rod bearing failure. The repair order states: "replace engine assembly due to piston slap on front bank caused by rod bearing failure. " the dealer says the entire engine must be replaced. The vehicle has been maintained with regular oil changes. The failure was internal and was not caused by a crash, impact, or outside damage. I believe this is a safety defect. A connecting rod bearing failure can cause the engine to stall or seize without warning while driving, including at highway speed, creating a risk of a crash. A failed rod can also break through the engine block and leak oil onto hot engine parts, which is a fire risk. The vehicle is past Hyundai's 100,000-mile powertrain warranty. I have opened a case with Hyundai consumer affairs (case # 43347615) and am waiting for a decision. The vehicle and failed engine are available for inspection at the dealer. I am asking NHTSA to investigate connecting rod bearing failures in the 3. 8l v6 engine in the 2020 Hyundai Palisade.

The vehicle experienced severe engine stalling and critically low oil levels that were officially documented by an authorized dealership well before 100,000 miles (at approximately 79,000 miles). Because this pre-existing condition remained unresolved under warranty, the engine ultimately failed and required a complete replacement at approximately 103,000 miles. Just 7,000 miles later, at 110,000 miles, the automatic transmission suffered a critical failure. The transmission severely shudders, spikes to excessively high rpms, and refuses to shift properly through lower gears (gears 1 to 3). This causes sudden hesitation, loss of motive power, and violent jerking when accelerating and merging into active traffic, creating an imminent crash hazard. The manufacturer has refused repair assistance despite cascading powertrain defects that originated prior to 100,000 miles.

Due to a known oil consumption issue the manufacture replaced the engine using a short block swap, they used the old fuel injectors and during the swap one of them failed, becoming stuck open. Now they refuse to fix it without me paying for labor. The failed fuel injector occurred immediately following a mandatory manufacturer engine replacement and poses a thermal/fire hazard.

I have been dealing with the oil consumption issues for this vehicle for about 2 years now. There are documented complaints and a class action lawsuit in California about this issue. Bottom line, the engine burns too much oil to be safely driven between oil changes without the owner checking and adding oil. My particular vehicle is burning just under 1 quart of oil per 1000 miles. Hyundai’s owner manual suggests changing the oil every 7,500 miles, but the oil capacity is under 6 quarts. At the current rate, I would run out of oil before the suggested oil change interval. This is a severe safety issue as engines require oil to run correctly, not overheat, and lubricate all the moving parts. The previous generation Hyundai models also had similar oil consumption issues. Those vehicles had a NHTSA campaign which resulted in Hyundai being responsible to fix the engines. I believe a recall is proper given the safety concerns noted above. At a minimum, Hyundai should stand by their work and fix the issues as they arise.

On September 21, 2026, at approximately 9:20 am, while attempting to turn off the engine of the parked vehicle, the engine failed to shut down as commanded. Due to severe ecm misfire and erratic anti-stall compensation, the engine surged uncontrollably and propelled the vehicle forward. The forward collision-avoidance assist (fca) completely failed to detect the obstacle, alert the driver, or apply emergency braking, resulting in an unavoidable low-speed collision and slight front-end body damage. The following day, on September 22, 2026, at approximately 2:49 pm, the vehicle abruptly triggered a powertrain fail-safe mode in traffic, forcefully restricting speed to roughly 20 mph (limp-in mode), when my wife found it when trying to running faster from a stop mode, to prevent catastrophic catalytic converter damage caused by persistent combustion misfires. It is impossible to be the wrong operation of my wife since limp-in mode cannot be activated during low speed running. On September 23, 2026, the vehicle was taken to an authorized Hyundai dealership to apply pending TSB 26-01-068h (campaign 9d6). While the dealer completed the software update and reported no active dtcs remained afterward, Hyundai motor America has flatly denied manufacturer liability for the property damage incurred directly prior to this safety remedy. Hyundai's ecm software logic flaw poses a critical safety risk involving unintended acceleration, complete shutdown failure, and active safety system non-intervention. I request NHTSA investigate this defect and Hyundai's refusal to remediate related incident damage.

Defect & safety hazard: severe internal manufacturing defect causing catastrophic engine oil consumption and sudden, un-warned engine stalling. The vehicle completely shuts down at highway speeds, on inclines, and at stops. This sudden loss of motive power deactivates power steering and braking assists, creating an immediate multi-vehicle collision risk. No low-oil or dashboard indicators illuminate prior to stalling, stripping the driver of any ability to take proactive safety measures. Indisputable failure data: between 99,xxx miles (under warranty) and 103,xxx miles, the engine consumed 5. 5 quarts of oil over a 3,000-mile interval. This equals an extreme burn rate of 1. 83 quarts per 1,000 miles. Hyundai’s maximum corporate failure limit (1. 0 qt/1,000 miles). Secondary diagnostics indicate this massive volume of un-combusted oil is actively pushing into the exhaust system, creating restrictive backpressure that induces stalling. Timeline & dealer obstruction:rusty wallace Hyundai: inspected vehicle under 100,000 miles and initiated the first 1,000-mile consumption test, but subsequently refused documentation and further warranty services. A corporate national claim and customer service complaint were filed against them. Grayson Hyundai: completed a second 1,000-mile test documenting a definitive failure. They confirmed this is a common, known systemic issue and recommended full engine replacement. Federal violations: under the magnuson-moss warranty act, because the defect was reported to a dealer before warranty expiration, Hyundai is legally required to cover the defect. Forcing a vehicle that burns 5. 5 quarts of oil onto public roads also violates strict epa clean air act emissions compliance standards. Hyundai's current demand for out-of-pocket payment must be rescinded for full corporate coverage.

I do not understand how Hyundai can approve its required testing process, have the vehicle fail that test, and then deny the engine replacement resulting from those findings. This is unfair and raises serious concerns about how Hyundai is applying its warranty procedures. Hyundai’s published oil-consumption procedures establish a process for diagnosing excessive oil consumption and determining when further repairs, including engine replacement, may be warranted. I am requesting that Hyundai explain exactly what requirement my vehicle allegedly failed to meet and provide documentation supporting the denial. I am requesting that Hyundai reverse the denial and fully cover the necessary engine replacement under warranty. I also request a complete review of my maintenance history, repair records, oil-consumption test results, diagnostics, and the dealership’s submission. This vehicle has been properly maintained and has only approximately 80,000 miles. I purchased it expecting a reliable vehicle that would last many years. An engine developing excessive oil consumption at this mileage is unacceptable, and I believe Hyundai should stand behind its product and warranty obligations.

My 2020 Hyundai Palisade (3. 8l v6) has a persistent engine defect causing sudden stalling and severe oil consumption. Since mid-2019 the engine has stalled without warning when coming to a stop, idled roughly, and made loud puttering noises under light acceleration — a loss-of-power hazard in traffic. In 2026 the dealer began formal oil consumption testing. Although 1,000-mile checks were marked 'passed,' the engine was found completely dry (dipstick showed no oil) at 2,000 miles — 3. 5 quarts low on a 6. 1-quart system. On 09/02/2026 the vehicle failed an official oil consumption test at Hyundai of kirkland and was held for service. The dealer performed a carbon-cleaning procedure, but the underlying oil consumption is unresolved and a re-test is now underway. Running an engine at less than half its oil capacity risks sudden seizure or stall at speed. I am concerned this is a systemic defect affecting other 2020 Palisades and request NHTSA investigate.

Component affected: fuel system, gasoline: delivery: high pressure pump description of the safety hazard: my 2022 Hyundai Palisade has developed a catastrophic failure of the engine-mounted high-pressure fuel pump (hpfp). The insulating foam cover is completely saturated and leaking raw, liquid gasoline directly on top of the engine block. The fuel system is unable to maintain rail pressure, causing severe pre-detonation engine knock ("pinging") and mechanical stumbling during acceleration. Furthermore, there are visible electrical flashes/short-circuit arcs occurring in the engine bay directly adjacent to the high-pressure liquid fuel leak, presenting an imminent vehicle fire hazard. Active dark fluid puddles contaminated with fuel are dripping past the splash shields onto the ground. Dealer/manufacturer actions: despite clear photographic evidence of a pressurized fuel leak on a powertrain-covered component, multiple authorized Hyundai dealerships (fred beans, harrisburg, and chambersburg) have refused service or grossly misdiagnosed the life-threatening safety issue as a 'gas cap' or 'water hose. ' Hyundai motor America corporate consumer assistance has failed to intervene or provide emergency towing remediation for this severe fire risk.

The vehicle has experienced issues for roughly 6 months randomly not starting. The lights and displays come on but it will not respond to push start. We took it in and they replaced the starter assembly about a month ago. The next day it wouldn’t start again. That same weekend died twice and intersections with the auto stop start like the computer was rebooting. It went back into the shop a few weeks ago and they have been unable to isolate the issue. Opened up a case with Hyundai and it’s back at the dealer again tomorrow for them to work with hq technical teams.

At 16 thousand plus my car was at a stop light and stop/stalled/shut down what ever you want to call it. The auto stop was on but this was not the problem. I physically had to restart my car in traffic. The next time I experience this was at 20 thousand plus. We were in the hospital parking garage and the car again stop/stalled/shut down and I physically had to restart it again. This time I was driving with the auto stop off. I have experience this again at 21 thousand plus. Again I was at a stop light. The auto stop was off. The car stall/stop/completely shut down again. Car had to be restarted while again in traffic. Hyundai had been notified of the stall/stops. This was the last time I was dealing with this problem and took it into happy Hyundai in libertyville illinois. They had it for a week. They did run test, but the car was not giving any codes. Happy Hyundai did not run it over the weekend for on my bluelink I get notification. On Monday my husband called and told them to drive it because this is when we are experiencing the problem. Happy Hyundai drove it once. Tech was not able to replicate it. My husband also took happy Hyundai to let it run. They let the car run. This is what happen when we were in the hospital parking lot. We were sitting. The safety of the person driving the car is at risk for a accident. There have been reports on they Hyundai facebook web sites of the car stalling while driving at speed. I carry my handicapped daughter in my car. This stall/stop becomes a worry some problem, not knowing when it is going to shut off again. This has caused me much anxiety. I don't even want to drive my car. This is a accident waiting to happen. Along with many law suite's. No dash board cluster lights were on when the car stall/stop. Car has been inspected by happy Hyundai and is now going back per Hyundai coporate wanting a tech to pull codes.

In the past two weeks, our 2021 Hyundai Palisade has shut off completely when driving. It has around 110,000 miles on it and was just purchased used (second owner) three months ago. At that time, the dealership had to fix a leak in the engine and did a complete oil change. Based on internet searches, we just checked the oil dipstick and it is completely empty. We have not driven more than 3,000 miles since purchasing the vehicle and there is absolutely no oil left. Based on searches, it appears this is a fairly common, known issue and nothing is being done. It is incredibly dangerous that the car shut down while driving (on the highway, in the middle of a right-hand turn). Every single warning light lit up at once then the car completely shut off within a matter of seconds. Thankfully my husband was able to get to the side of the road and no accidents occurred, but this is terrifying and completely unacceptable. The car is going to be towed to the dealership to check for excessive oil consumption, but again, based on research, it appears that this is a known issue but Hyundai says it is "within acceptable limits. " please do something about this before someone is seriously injured or killed.

On August 14, 2026, while driving and decelerating, I heard a knocking sound from the engine and the vehicle had difficulty downshifting. As the transmission shifted from second gear to first, the engine stalled immediately and the vehicle dropped into neutral while on the roadway. I lost propulsion in traffic. The vehicle behind me nearly rear-ended us due to the sudden stall. My children were in the vehicle. All dashboard warning lights illuminated at the moment of the stall. I was able to restart the engine and move the vehicle slowly, in first gear only, into a nearby parking lot. The check engine light came on at that restart and has remained on since. The vehicle sat parked and off for approximately 90 minutes. Before restarting, I checked the engine oil level and it was within the normal range. On startup, my children and I both heard a loud knocking sound and noticed an unusual smell, and the engine idled roughly while in park. I drove approximately 15 minutes home with the rough idle continuing. On arrival the vehicle smelled hot, with a burning odor, although the temperature gauge read approximately mid-scale and was not in the high range. The check engine light remained on and the oil level was again confirmed to be within range. The vehicle has been out of service since the incident and is currently at a dealership awaiting diagnosis. This is a 2020 Hyundai Palisade with approximately 93,000 miles at the time of failure. A sudden loss of motive power in a travel lane is a safety defect.

Vehicle: 2022 Hyundai Palisade, approximately 78,000 miles. The vehicle has experienced a recurring engine/powertrain malfunction involving engine stalling, hesitation/rough operation, startup rattling, cylinder air/fuel imbalance, and misfires. The exact failed component is currently unknown. The vehicle is available for inspection upon request. The vehicle has stalled at low speeds, creating a safety concern because the engine can unexpectedly shut off or lose power while the vehicle is being operated in traffic. Unexpected stalling could leave the vehicle without normal acceleration when entering or crossing traffic and creates a risk of a collision involving the occupants or other motorists. The vehicle has been evaluated and serviced by a Hyundai dealership for engine-related concerns. Diagnostic trouble codes associated with these problems have included p000c, p219d, p219f, p21a0, and p0302. Of particular concern, p219d, indicating a cylinder 2 air/fuel ratio imbalance, has occurred repeatedly, and the vehicle subsequently generated p0302, indicating a cylinder 2 misfire. This suggests a recurring problem involving the same cylinder, although the underlying cause remains unknown. Previous repair efforts have included work involving the vehicle's vvt system, but the engine-related problems and diagnostic codes have continued/recurred. The vehicle/component has been inspected by a Hyundai dealership. To my knowledge, it has not been separately inspected by police, insurance representatives, or NHTSA. Whether Hyundai corporate/manufacturer representatives have directly inspected the vehicle is unknown. Prior to and during these incidents, symptoms included the check-engine warning light, startup rattling/noise, engine hesitation/rough operation, and stalling at low speeds. Diagnostic codes were stored when the check-engine light appeared. The problems have occurred on more than 100 occasion rather than being a single isolated incident.

I had an oil change in Feb 2026 at 64000 miles. In June, I was driving the car and suddenly the car started jolting while I was idle and would turn off completely when I was stopped. This happened to me while driving on the freeway in traffic and also at a traffic light. I immediately went to the dealership and was told my car had no oil in it. Since the oil change I drove about 5900 miles. I was told there were no leaks so the issue was either the engine or that when I had the oil changed that they forgot to put the oil in. They advised to get an oil test. I drove 1000 miles and took the car back in today 8/11. I had the oil tested and I burned . 4 quarts in the 1000 miles which was under the standards of 1 quart per 1000 miles in order to get the issue fixed. I was told that I needed to check my oil and add oil to the car when needed. I left the dealership confused because I have had this car for over a year and never had an issue with the oil or oil levels. I never had any oil indicator on my dashboard to alert me of any issue. I called back the advisor asking more questions because I did not understand how my car burned through so much oil that it was malfunctioning. After being talked to like an idiot about how it is my responsibility to make sure my car has oil, I was finally told that this Palisade has a known issue for premature oil consumption once it hits 60000 miles. Then I was told there is no recall and the issue will only get worse and I have to wait till it hits 1 quart of oil burned in 1000 miles for anything to be done. I feel like this is extremely irresponsible of the company to know this issue exists with nothing being done or communicated to their customers and that it is a huge safety concern to not have any indication there is something wrong with the oil amount and my car could literally stop in the middle of the freeway. They are waiting to make the issue neglect from the customer so they are not held responsible for their vehicle's issue.

While driving the vehicle, the accelerator pedal was pressed but the vehicle failed to respond and did not accelerate, it simply rolled slowly as the engine continued to idle. The driver increased throttle input in an attempt to get the vehicle to accelerate. The vehicle continued to show no response to the additional throttle. After a delay, the vehicle suddenly resumed normal operation while the higher throttle input was still applied. This resulted in an abrupt and undesired surge of power. While this was occurring, another vehicle was rolling forward in preparation for a left turn. The other driver appeared confused by the Palisade’s lack of acceleration (apparently believing it was yielding) and had not yet turned into the path of the Palisade. The sudden surge of power created a near-miss situation. This incident involved a delayed response to throttle input followed by a sudden surge of power under increased throttle when the vehicle resumed normal operation. The behavior created a safety risk by causing another driver to misjudge the vehicle’s intentions and by producing unexpected lack of acceleration followed by acceleration at a critical moment. This is consistent with ongoing intermittent throttle and power-response issues that have previously been reported to the selling dealer on multiple occasions.

This vehicle has suffered two identical, catastrophic electrical failures causing an immediate and total loss of engine power while traveling at highway speeds. The first incident occurred after the engine was replaced under a Hyundai extended warranty. The dealership service department blamed that failure on a loose engine ground strap and released the vehicle back to me. On August 3, 2026, the exact same failure occurred for a second time while driving at high speed on the highway. The vehicle lost all propulsion, leaving me exposed to oncoming traffic with zero engine power. The vehicle was towed to a Hyundai dealership. The dealership identified a blown "sensor 4" fuse causing an intermittent dead circuit, but they have been unable to locate the short circuit after two weeks of troubleshooting. After demanding the diagnostic data logs, the dealership abruptly halted all repairs and ordered me to pick up the vehicle. Furthermore, due to excessive, repetitive diagnostic cranking and idling in 90+ degree heat while under the dealer's care, the vehicle's starter solenoid has now suffered collateral failure. The vehicle is currently completely disabled, undrivable, and the underlying highway stalling hazard remains completely unresolved. This is a recurring, severe life-safety issue that leaves the vehicle prone to sudden stall events in high-speed traffic without warning.

The vehicle's steering wheel completely locks up in mid-turn while actively in motion. Berman Hyundai of lincolnwood performed massive engine and transmission overhauls but twice willfully ignored my warnings about this catastrophic steering defect. The dealership is refusing a safe loaner vehicle. The car is currently grounded at napleton Hyundai for an emergency independent diagnostic. An active corporate case is open with Hyundai motor America under case management #43278436. All this and I’m not even done paying the vehicle.

Excessive oil consumption. Oil tank empty at 3 oil changes. Car was stalling at stops. Oil was empty 5000 miles prior to next suggested oil change. No low oil indicator light alarm.

On or about July 23 2026 I brought my vehicle into the dealership as my 2020 Hyundai Palisade suffered a severe, sudden engine malfunction while driving at highway speeds. The vehicle began shaking violently, losing power, and making loud mechanical noises forcing me to navigate dangerous highway traffic to get it to the dealership. Prior to the failure, in March of 2026, the vehicle was brought into an authorized dealership as the vehicle would not drive properly, very slow acceleration and the vehicle feeling like it was stalling causing a danger to the road. . The dealership performed an inspection on the vehicle and diagnosed "carbon buildup due to mileage and age," they performed an authorized emissions software update, changed the oil, and performed a paid fuel injection cleaning. The dealership did not issue a safety warning or advise against driving the vehicle long distance back to new york. A few months after this service, the vehicle suffered total engine failure. Professional teardown of the Hyundai lambbda ll v6 engine show that unresolved carbon buildup and software defects lead to piston ring failure, severe misfires, oil starvation, and sudden loss not motive power. Operating a vehicle experiencing severe mechanical shaking and power loss at highway speeds poses an immediate risk of an accident.

My wife was driving the vehicle to work this morning xxx around 730am on the [xxx] near [xxx] and the vehicle just cut off while driving at high speed. All the lights were activated on the dashboard. The steering wheel locked, the brakes stopped working, and the car would not accelerate. The vehicle died mid drive placing her in a dangerous life threatening predicament within this heavily trucked corridor. She was left to block traffic until help arrived. The vehicle was towed to the Hyundai dealership on eucalyptus in moreno valley. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

After the "9c9" emissions recall update the vehicle randomly fails to respond to appropriately throttle input when attempting to accelerate into traffic. The issue is very intermittent - it may occur twice in 10 minutes or drive fine for hours. It has demonstrated both a "bucking" / stuttering / misfire feeling as well as a complete lack of any throttle response. After a few seconds of bucking, the vehicle returns to normal and accelerates smoothly with no change in throttle input. If the throttle failed to respond, pumping the pedal a few times has resumed normal operation. Situation has occurred multiple times since the update and has allowed the vehicle to roll into traffic without the ability to promptly accelerate to speed creating a safety hazard. There are no warning lights, and the dealership is unable to reproduce the issue.

When attempting to use engine braking to control descent on mountain roads, the vehicle failed to slow. Engine rpms increased and speed increased requiring significant brake usage. Last year the vehicle performed as expected as deceleration was controlled via downshifting with much less brake usage. The only change was the application earlier this year of Hyundai service campaign 9c9.

The contact owns a 2022 Hyundai Palisade. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The contact stated that several unknown warning lights were illuminated, and the engine seized. The contact stated that while attempting to start the vehicle, the vehicle started. The vehicle was taken to the dealer. In addition, the unknown warning lights were off. The failure was not duplicated. The contact stated that the vehicle was taken to the dealer three times within a month. The failure was intermittent. The manufacturer was made aware of the failure. The failure mileage was approximately 70,000.

Alternator failure: my family and I were moving to [xxx] from [xxx]. A few hours into the drive, the vehicle battery light came on. It was intermittent though. It would be on for a little while 10-15 mins and then shut off and then repeat this process. I stopped at an autozone and they tested the battery and it was showing a charge of 7%. I could not afford to get stranded somewhere so I went ahead and had the battery replaced, even though I suspected the alternator was going bad. We continued on the trip, but the battery light continued to turn on and off. The vehicle ultimately began losing power about 2 hours after replacing the battery, causing all the warning lights on the dash to turn on, the main center console display lost power and then I lost power steering. All of this happened while I was on the interstate, putting myself and my family in serious danger. I was able to pull the car off an off ramp and park it safely. I called a tow service to take it to the nearest Hyundai. The dealership verified the alternator was bad, but later found that the tensioner assembly had also failed and would have caused serious damage if they had not caught it. The vehicle has since been repaired under warranty, but I researched and found this is a common failed item. The vehicle only has 33,253 miles on it, and is barely 2 years old. Alternators should not fail like that. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While driving down the freeway my first row sunroof exploded. Insurance wouldn’t cover it because it is a manufacturer defect, but Hyundai wouldn’t cover it because it “isn’t a manufacturer defect. ” the temperature outside when the sunroof exploded was 74 degrees and it was cloudy. Then less than 2 months later my engine got a rod knock even with oil changes every 5k miles. No warning signs for either and no lights on the dash. It just started when I started it to leave for work one morning.

Vehicle developed a check engine light and underwent warranty repair, during which all six fuel injectors were replaced (repair order #1hws5031079, dated 7/8/2026, 33,768 miles). Despite this repair, the check engine light returned, and the vehicle subsequently developed an intermittent hard-start and no-start condition — in some instances the engine would not start on the first attempt and required a second attempt. The vehicle was returned to the dealership for a second repair visit (repair order #1hcs55031999, dated 7/28/2026, 34,090 miles), during which the dealership considered multiple possible causes, including a sensor issue and fuel-related concerns, before completing the repair. The vehicle was out of service for a cumulative total of approximately 22 days across both repair visits. An intermittent no-start condition raises reliability and safety concerns, particularly in situations requiring predictable vehicle operation.

I am reporting a potential safety defect involving my 2021 Hyundai Palisade calligraphy awd. The vehicle has experienced repeated engine and drivability problems and multiple breakdowns following replacement of the engine by Hyundai. The original engine developed excessive oil consumption and was ultimately replaced by Hyundai with a new engine. Following the engine replacement, the vehicle experienced numerous additional mechanical problems and repair attempts, including engine rattling/pinging, intake-manifold replacement, oil valve-seal replacement, multiple cylinder misfires, ignition-system problems and an ignition-coil failure. Most concerning are repeated incidents involving severe shaking/lurching, loss of engine power, stalling and failure to restart. During one incident following repairs, the vehicle ran extremely rough, stalled and would not restart after approximately 20 miles of driving and had to be towed back to the dealership. During another incident, the vehicle experienced heavy shaking on startup, stalled and had severely limited power. Diagnostic history showed misfires involving multiple cylinders. On June 29, 2026, at approximately 103,671 miles, I was driving at approximately 50 mph when the vehicle began to lurch and shake, lost power, stalled and would not restart. The vehicle had to be towed back to the Hyundai dealership. The unexpected loss of propulsion and stalling while traveling at approximately 50 mph created a serious safety concern because I could no longer rely upon the vehicle to maintain power in traffic. The dealership subsequently identified an ignition-coil short/failure and replaced an ignition coil. The vehicle has nevertheless continued to experience additional mechanical problems. The vehicle is currently again at the Hyundai dealership. It has generated diagnostic code p0430 for bank 2 catalyst efficiency below threshold, and Hyundai has recommended replacement of both catalytic converter/manifold assemblies. Th.

The contact owned a 2025 Hyundai Palisade. The contact stated that while driving 25-30 mph on a curvy road, the steering wheel suddenly locked up, and the vehicle failed to drive in the intended direction, drove down the street, into a yard, and the front end of the vehicle crashed into a tree.

My properly maintained 2020 Hyundai Palisade suffered catastrophic engine failure at 77,000 miles. Importantly, prior to the engine failure, no check engine lights, low oil warnings, or other warning indicators were active or displayed. The vehicle gave no indication of an imminent catastrophic engine failure or lack of oil. In researching this matter, I have found numerous reports, as well as active and settled litigation, involving Hyundai engine failures and oil consumption concerns. Severe oil starvation due to engine manufacture issues caused a thrown rod which can result in fire. The car was being driven by my teenage son after dark and the engine completely shut down putting him in harm's way in the middle of the road. Hyundai has repeatedly refused my requests for assistance in repairing this known issue due to my being a second owner with a lesser warranty that is given to 1st owners. This issue is a safety concern and a known issue to hca and should be a recall to insure it stops happening.

What component or system failed or malfunctioned, and is it available for inspection upon request? rear exhaust system how was your safety or the safety of others put at risk? fire hazard as it was similar to a blowtorch, melted several rear panels, lights and trim while driving. Has the problem been reproduced or confirmed by a dealer or independent service center? the dealership (elyria Hyundai) requested a PA from Hyundai and it was authorized, but am having a very difficult time getting reimbursed. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? I am not sure what the dealership did with the exhaust. At one point, I had requested to keep it for evidence. There are pictures. I suggested having the manufacturer look at it or at least Hyundai. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? there were no warnings. After a 2. 5 hr trip, we got out; my children noticed the trim sticking out and melted off the rear right bumper. It was extremely hot to touch and the panels were bulging out from their normal position.

I was driving my 2026 Hyundai Palisade on a busy road when the vehicle suddenly stopped without warning. A message appeared on the dashboard stating that the engine was off. I did not turn off the vehicle. This created a dangerous situation in traffic.
