Engine And Engine Cooling Problems of Hyundai Palisade - part 2

The vehicle would shut off when idling at lights or in reverse and have delayed acceleration after stops. It also would shut off when idling in park. I took it to the dealership summer-fall 2025 and they were too busy to investigate the issue because no alarms were present. The vehicle started doing the same thing and the check engine light came on March 2026. Now it has been in the shop for many weeks because of an fuel injector issue. The dealership service department says all 6 injectors need to be replace, but warranty won't cover them all. This appears to be a common issue with 2021 Hyundai Palisade vehicles and should be investigated for a safety recall.

The contact owns a 2022 Hyundai Palisade. The contact stated that the vehicle was parked for nine hours unattended in the middle of the night; it caught fire. No warning lights were illuminated before the fire. The vehicle was taken to an unknown local dealer two weeks prior for a recall repair and oil change. While her husband was extinguishing the fire, he sustained burns to his arms and face, but medical attention was not provided. Additionally, part of the home was burned. The fire department was able to extinguish the fire. There was no police report filed, no air bag deployment, or crash. The vehicle was towed to a storage facility by the insurance company. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was approximately 82,000.

1. The exact component that failed is unknown at this time. The fire appeared to originate in the driver-side front area of the engine compartment near the headlight. Prior to the fire the vehicle experienced engine shaking and a check engine light. The vehicle has been towed to a Hyundai dealership and is available for inspection by insurance investigators, the manufacturer, or safety investigators upon request. 2. The vehicle caught fire while it was being operated on a public roadway shortly after leaving our residence. Flames were visible from the engine compartment within minutes of driving. This created an immediate safety risk to the occupants of the vehicle and to other motorists because the fire occurred suddenly while the vehicle was in motion. 3. The problem has not been reproduced. The vehicle was towed to a Hyundai dealership following the fire incident and is awaiting inspection. The vehicle is a total loss. 4. The vehicle has been inspected by a tow operator and insurance representatives after the fire incident. The vehicle is currently located at a Hyundai dealership and may be inspected by the manufacturer or investigators if requested. 5. Yes. Prior to the fire the check engine warning light illuminated and the engine began shaking while the vehicle was being driven. Within moments of these symptoms a loud popping sound was heard from the front driver-side engine compartment area, followed by visible flames.

While driving at normal speed, my 2022 Hyundai Palisade suddenly lost power without warning. Multiple warning icons appeared on the dashboard at the same time. The vehicle immediately slowed down and became unsafe to operate. After pulling over, the vehicle would not restart and had to be towed. This created a dangerous situation on the roadway. I am reporting this because I wonder if other owners may have experienced similar sudden power-loss events with this model year. It was fortunate that I was on a secondary road and not on the highway when this happened because it could have resulted in fatalities.

The engine burns 1 quart per 1000 miles of driving.

My 2020 Hyundai Palisade has an excessive and dangerous oil consumption defect. The vehicle consumes approximately 3/4 of a quart of oil every 1,000 miles. At a standard 8,000-mile oil change interval, the engine loses more oil than it holds between services. At approximately 185,000 miles, my vehicle stalled on the interstate with my family inside the vehicle. Upon inspection, the engine was critically low on oil. I added 5 quarts of oil to restore proper level. Critically, at no point prior to the stall did the low oil pressure warning light illuminate. The vehicle's oil warning system completely failed to alert me that the engine was dangerously low on oil. This is a dual failure: the engine is consuming oil at an excessive and unsafe rate, and the warning system designed to protect the driver failed to activate when the engine was in a critical state. I have reported this issue to my dealership and filed a formal complaint with Hyundai motor America. Neither has resulted in a meaningful resolution. Hyundai's internal "acceptable" oil consumption threshold of 1 quart per 1,000 miles is significantly outside mainstream industry standards set by other major manufacturers and appears designed to deny warranty claims rather than protect consumers. This defect poses a direct and serious safety risk. A vehicle stalling on the interstate due to oil starvation, with no warning to the driver, is a life-threatening failure. I am requesting that NHTSA open a formal investigation into the 2020 Hyundai Palisade for excessive oil consumption and oil pressure warning system failure.

Hyundai's recent emissions software update (9c9) has disabled engine braking, creating a risk of brake fade on grades. The vehicle is no longer able to hold speed while descending grades, regardless of downshifting, forcing the brakes to be implemented to avoid excessive speed. This was never an issue prior to the software update and happened immediately after the software was installed. Instead of holding the vehicle with the engine (foot off the gas, and downshifting) the engine will continue to increase speed up to the point of approaching maximum rpms. Further evidence of this behavior is that trying to use the engine braking no longer shows maximum mpg on the dash, indicating the software update is still feeding fuel to the engine with the foot off the gas.

I am reporting a safety concern involving my 2026 Hyundai Palisade limited involving repeated engine malfunction warning lights and diagnostic trouble code p001600 (camshaft/crankshaft timing correlation fault). This issue has occurred multiple times within the first 60 days of ownership and the vehicle has been taken to a Hyundai dealership twice. The dealer has not been able to determine a permanent repair and states the code is stored as a history fault without an available fix at this time. This defect is concerning because camshaft/crankshaft timing correlation faults can potentially result in engine stall, loss of power, or unexpected shutdown while driving, which could create a serious safety risk. I routinely drive long distances and transport two small children in this vehicle and no longer feel confident in the safety and reliability of this vehicle due to the unresolved engine defect. Additionally, I understand there is a recent safety recall affecting certain 2026 Hyundai Palisade vehicles, which increases my concern about the safety of this vehicle platform. I am submitting this complaint because this appears to be a potential safety defect involving engine operation that could affect safe driving conditions.

Vehicle is consuming or burning oil at a high rate. While dealer has done an oil consumption test and claimed it was "within tolerance," I have on multiple occasions had the car start to shudder at 2,000 miles since last oil change only to find the oil wasn't even on the stick anymore. The symptoms go away when adding oil, on some occasions more than 4 quarts of oil need to be added to get the oil to "full" on the dip stick. Multiple independent service centers have noted how dirty the oil is and how little is drained on oil change. No warning lights have come on at any time, even when car is making grinding noises and shuddering with no oil. This causes a safety issue as drivers reasonably expect to go at least 3,000 miles between oil changes and the engine could seize in traffic. Owners are being tacitly asked to add oil regularly to keep the engine functioning properly.

The contact owns a 2020 Hyundai Palisade. The contact stated that the vehicle was consuming an excessive amount of oil. There was an oil-burning odor coming from the vehicle. There was a misfire coming from the engine before the vehicle stalled. The auto start/stop was activated while driving. The feature was turned off, but quickly reactivated. There were no warning lights illuminated. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 89,000.

Description of incidentthe vehicle experienced a severe engine system defect and catastrophic internal mechanical failure. The primary symptom prior to the failure was excessive, rapid engine oil consumption between scheduled maintenance windows. The issue was officially confirmed by an authorized dealership service center, where diagnostic testing verified that the engine has critically low cylinder compression in cylinder 1. The vehicle is currently completely incapacitated, and the disassembled engine block remains at the dealership facility available for inspection upon request. Safety risk assessmenta sudden and severe loss of internal engine cylinder compression creates a critical vehicle performance defect, an immediate stall risk, and a catastrophic hazard when operating on high-speed roadways. In this instance, the mechanical failure completely disabled the household’s primary, medically modified means of transport. Because the manufacturer and dealership failed to maintain or provide a structurally or layout-compliant alternative vehicle, a permanently disabled occupant was forced into a tight, non-accommodated cabin geometry. This directly induced severe physical trauma, muscle spasms, and an immediate loss of lower extremity neurological sensation while operating the replacement vehicle. The combination of a catastrophic powertrain failure and a total refusal by the dealer and manufacturer to provide an accessible replacement layout has completely stripped a vulnerable consumer of independent mobility and created a severe, ongoing physical safety hazard.

This vehicle is still using the defective style piston rings causing oil consumption of 1. 5qts in 1000miles, with only 100,000miles. This has been ongoing since we purchased the vehicle with 94,000 miles. This needs to be issued as a recall to replace piston rings or the engine entirely. My valuemax level 4 extended warranty is refusing to repair the issue stating Hyundai/kia has carbon buildup on the piston rings. This engine could run low on oil and cause a fire, or a engine shut down causing a crash.

The engine in my 2021 Hyundai Palisade experienced sudden loss of oil leading to engine failure. The vehicle had been regularly serviced and maintained at a Hyundai dealership according to recommended intervals. During multiple service visits, the dealership informed me the vehicle was low on oil. An oil consumption test was performed but the results were inconclusive. At approximately 99,500 miles, the vehicle developed an oil leak which the dealership diagnosed as a gasket issue and repaired under warranty. An oil change was completed at that time. Approximately 5,000 miles later, while driving, the vehicle began experiencing loss of power and rough engine operation. I immediately drove the vehicle to the dealership. The dealership later informed me the engine had no oil in it when inspected. There were no active external leaks observed at that time. The dealership stated that it is “normal” for this engine to consume up to one quart of oil per 1,000 miles. The engine now requires full replacement due to internal damage caused by oil loss. This situation created a safety concern because the vehicle began losing power while in operation. The failure occurred suddenly without warning indicators prior to the loss of engine performance. The vehicle had documented oil level concerns during previous service visits, suggesting a potential excessive oil consumption or engine defect. The failed engine is currently available for inspection at the dealership.

The contact owns a 2026 Hyundai Palisade. The contact stated that the vehicle turned off on several occasions after the engine auto start/stop system was engaged. The vehicle was restarted and was taken to the dealer; however, the failure could not be duplicated. Additionally, upon starting the vehicle after the vehicle was refueled at a gas station, the check engine and several other unknown warning lights were illuminated, and the vehicle failed to respond while shifted to drive(d). The vehicle was towed to the contact's business. The vehicle was then towed to the dealer; however, the vehicle was not diagnosed because there was no warning light illuminated. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 5,463.

My car is consuming too much oil. I am going through almost 2 qts per 1,000 miles. Combustion cleaning and consumption test have been completed with no fix to the problem.

While idling at a traffic light on a busy city street all of the warning lights on the car went off and the car shut off on its own.

I have the video but I am unsure how to upload or share incident description: the vehicle is experiencing intermittent, complete engine stalls while in motion at highway speeds. The failure has occurred four times. Initial symptom: the issue first manifested as "stuttering" and erratic behavior from the advanced driver assistance systems (adas) which I thought it was. Escalation: the vehicle has since progressed to a total loss of power. During these incidents, I was forced to pull over on high-speed corridors (hwy 46 and hwy 5) to restart the vehicle. Recurring pattern: most recently, after a stall and restart, the vehicle stalled again within a few blocks. I have captured video evidence of the stall occurring immediately after the vehicle was "reset" and put back into motion. Safety concern: this is a life-threatening defect. The vehicle loses propulsion without warning in high-speed traffic. The manufacturer’s service department (Hyundai) has been unable to identify a diagnostic fault code, citing "no problem found," and has only attempted a software/values reset, which has failed to correct the physical stalling.

While driving on a California freeway at approximately 70mph, the engine check light began flashing, the vehicle experienced a sudden and severe power loss, entered reduced power mode, and began violently shaking. Engine braking occurred without brake light activation, creating an immediate rear-end collision risk from following traffic. The vehicle would not stop shaking until restarted. This occurred twice — once in January 2026 and again in March 2026, both on the freeway with passengers in the vehicle. The dealer confirmed fault codes p0303 (cylinder 3 misfire), p0306 (cylinder 6 misfire), and p0300 (random/multiple misfire) on both visits. On the first visit the dealer called the codes normal and returned the vehicle unrepaired. The second visit lasted 44 days. The dealer could not reproduce the fault during the entire 44-day period. A Hyundai field service engineer physically visited the dealership and applied a special software update to the engine control module. The closed repair order documents this as "update special software into engine control unit" with no TSB number, no software version before or after, and no gds event number. The dealer confirmed they have no access to this update and cannot verify what was changed. No proof of correction was issued for California emissions compliance. The two recalls performed on the same repair order both have proper TSB numbers and stui documentation. The ecm update has none. Concerned about emissions compliance and potential fault code suppression on a California-registered vehicle.

Oil filter housing leak. Does not impact oil levels but more notable during cold weather as the ring tends to shrink.

I am reporting a safety concern involving repeated engine stalling while driving my 2020 Hyundai Palisade. The vehicle has stalled a total of seven times during normal operation. Most of the incidents occurred while slowing down or stopped at intersections and traffic lights. In these situations, the engine suddenly shut off without warning. I was forced to immediately shift the vehicle into park and restart the engine to continue driving. The check engine light did illuminate in connection with this issue. These incidents create a serious safety hazard, as sudden engine shutdown in active traffic increases the risk of rear-end collision. The loss of engine power occurs unexpectedly and without sufficient warning. The vehicle has been inspected, and I was informed that the issue may involve internal engine malfunction requiring major repairs. Because this vehicle has experienced multiple unexpected stalls in traffic, I am submitting this complaint due to the significant safety risk posed by sudden engine failure during operation.

Along with the two recalls of which I have not been contacted by Hyundai or provided any form of remedy, this is highly concerning and makes me feel extremely unsafe driving my vehicle, especially with the fact that I have small children and teenagers. My car had an issue from inception that I’ve let the dealer know about that. They still have not fixed including the fact that well I’ll be driving on certain roads are on the highway. It’ll come up with a warning telling me that I’m going the wrong way and try to engage the automatic breaking system. In addition, the second row seatbelt has been stuck and it won’t go back in. The third row seats often times try to disengage and come down. Anytime I hit a small bump or go over a speed bump even very slow. My bluetooth goes off-line as well as the navigation and then it comes back online within 3 to 5 minutes. Carr seems to have had a number of odd issues, including the way the engine has sounded as well as the electrical system is not engaging properly. I feel highly unsafe continuing to drive this vehicle and until all recalls and full proper analysis is conducted to remedy these issues I would want either a full refund of the cash value that I purchased my vehicle for, a brand new vehicle at no additional charge, or a loaner vehicle until all of these issues are remedied, and then a full analysis to ensure that it meets the standards. My preference would be to get a full refund of the cash value in which I purchased my vehicle for so I can get something else that is more safe for my family.

The vehicle engine shuts off out of nowhere, unable to change/switch between gears for 2-3 minutes after stopping at a red light, stop sign, or during heavy traffic, with no activation of the idle-stop-system before the incident. During the incident, the vehicle's steering was not able to turn. I have to keep my foot on the brake pedal for a while. After the second incident, I managed to drive the vehicle carefully and slowly to the dealership, but I was told there was no problem with the vehicle. So, I requested to take a drive with a mechanic, and the engine shut off in the middle of the street while slowing down for the third time. The dashboard reads "auto stop is off. " shift to p or n and start engine manually. Vehicle still at the dealership for 5 days.

Dear NHTSA, I'm reporting a serious safety issue with my 2020 Hyundai Palisade (3. 8l v6) involving excessive oil consumption without low-oil warning lights. Timeline: oil changed: August 13, 2025 ? engine stalling/rough idle ? checked oct 27, 2025: completely out of oil oil changed again: October 27, 2025 ? same symptoms recur ? January 16, 2026: completely out of oil again usage: ~300 miles/week (1,200 miles/4 months) using full synthetic 5w-30—far below Hyundai's 7,500-10,000 mile interval. Safety risk: no low oil warning despite total depletion x2, risking catastrophic engine failure while driving. Known lambda ii v6 issue per TSB 20-01-0001. Request: investigation into oil consumption recall and sensor failure.

On January 12, 2026, the vehicle shut off twice during the same trip while driving in traffic. All dashboard warning lights illuminated, the tachometer spiked, rpm readings did not correspond, the gear selector became unresponsive, and the vehicle lost propulsion while in motion. On February 15, 2026, the vehicle shut off again while driving under similar conditions. The vehicle was taken to a Hyundai dealership for diagnosis. The battery failed a load test and was replaced. According to the repair order narrative, after the battery replacement, the stall condition recurred during dealership testing. Multiple extended road tests and datalogging were later performed. The dealership has stated they are unable to re-replicate the condition and that no active diagnostic codes are present. The vehicle has experienced multiple loss-of-power events while in motion. An intermittent stall while driving presents a significant safety hazard, particularly in traffic conditions. The root cause has not been definitively identified.

The engine is burning oil at a rapid rate. It's burning one liter every 70 miles.

My 2025 Hyundai Palisade intermittently experiences an abnormally high engine idle of approximately 1,500 rpm during the first few minutes of driving. The condition occurs randomly and is not present on every trip. While stopped at stop signs or intersections with my foot firmly on the brake pedal, I can feel the engine pushing against the brakes because of the elevated idle speed. When I release the brake pedal, the vehicle accelerates forward significantly faster than it normally would at idle. The engine speed eventually returns to a normal idle after several minutes of driving, but during the event the vehicle behaves unpredictably. This has occurred on both flat roads and hills. I have documented the condition on video showing the tachometer at approximately 1,500 rpm while the vehicle is stopped and my foot is on the brake. The vehicle was inspected by an authorized Hyundai dealership and remained there for approximately one week. The dealership was unable to reproduce the condition during testing and returned the vehicle without repairs. No warning lights or messages have appeared. Because the condition is intermittent and results in unexpected forward acceleration when the brake is released, I believe it presents a potential safety risk.

Excessive oil consumption. The vehicle is burning nearly 4 quarts of oil between changes. This started at around 100,000 miles with no warning lights. The only indication was a strange tapping noise coming from the engine.

I am reporting a serious safety issue involving my 2025 Hyundai Palisade. The vehicle has repeatedly produced white smoke during cold start and has experienced loss of engine power while driving. Despite multiple repair visits (six times) to an authorized Hyundai dealership, the dealer repeatedly stated that the condition could not be reproduced and no repairs were performed. I provided video evidence of the white smoke and described the symptoms in writing at each visit. Shortly after the most recent service visit(12/22/25), within approximately five days, the vehicle displayed an “engine power limited” warning message and a malfunction indicator light (mil). When this occurred, the vehicle’s power was significantly reduced, making it difficult to maintain speed and creating a potentially dangerous condition, especially during highway driving or merging into traffic. This issue poses a serious safety risk because sudden loss of engine power can increase the risk of collision. The problem appears to be intermittent but recurring, and it has not been properly diagnosed or corrected by the dealership despite repeated opportunities. The vehicle has not been repaired for this condition, and the defect remains unresolved. The condition may be available for inspection upon request, and diagnostic data such as warning messages and onboard fault codes should be present in the vehicle’s system. The failure began with white smoke during cold start and later escalated to engine power limitation and warning lights.

Vehicle experienced engine failure previously and received a Hyundai-installed replacement engine in February 2025. Replacement engine is now setting dtc p000a00 – intake camshaft position slow response (bank 1). Hyundai dealership master technician confirmed excessive variance between commanded and actual cam timing, indicating a vvt / cam timing failure controlled by oil and actuators. Hyundai is refusing to cover diagnosis and repair under replacement engine warranty and is requiring customer-paid tear-down despite fault originating within the engine assembly. Concern is for internal engine timing failure that may lead to engine damage or loss of power. This appears consistent with known Hyundai engine timing and oil control issues.

I have been continuously receiving check engine notifications that show the engine cylinders misfiring. This seems to only happen at highway speeds which could cause a safety hazard should the driver need to accelerate for merging/passing/etc. I have brought this issue into the dealership once so far and they said they couldn't do anything since they were unable to replicate the issue while driving it. From what I've seen online, many other owners of this vehicle are having similar problems with the same responses from their local dealerships.

The first incident, my SUV failed to start, per roadside assistance, I replaced the battery. No diagnostic testing done. On 12/26/25 my SUV stopped cold while driving. Red battery light and other warning indicators on dashboard lit up. Radio went dead; loss of steering assist; loss of vehicle power; dashboard went black and SUV shut down. It would not start again. Towed to Hyundai for diagnostic test. I leave my home at 4:30 a. M. Every morning driving 30 miles on the beltway to work. Imagine the danger, stopping cold on the beltway, in the dark alone with no power for emergency lights to warn approaching traffic of the danger. I travel with my family in my SUV on the beltway daily. I no longer trust this vehicle, and I’ve requested to be reimbursed; my vehicle is my livelihood and it’s my life and the lives of my family each day that I get into this SUV. SUV is paid off. Rockville Hyundai’s finding was a faulty alternator and battery. The original battery was in the SUV with the first incident, still I’m terrified to drive this SUV. I researched possible causes for my SUV performing in this manner and my research yielded, and I quote:  “electronic troubles with the 2022 Palisade calligraphy often involve dashboard warning lights, driver-assist malfunctions, instrument cluster failures, and even engine shutdowns, frequently linked to issues like a faulty alternator, low battery voltage, or problems with the instrument cluster itself (recalls), with some owners reporting dangerous situations like loss of steering assist or vehicle power loss on the highway. ” on 1/6/26 on the beltway, the battery light and other warning indicators lit up; radio went dead, all warning indicators on the dashboard lit up; experienced loss of steering assist; and the dashboard went black instantly. I reached home, and parked; lights on the dashboard came back on, and I turned the engine off. On 1/7/26 I drove to Hyundai for another diagnostic test. 1/21/26 SUV still in service.

My radiator is leaking.

Occasionally, the car's rpms fluctuate wildly, and the engine stalls; the surges in rpm lead to sudden, abrupt acceleration, which poses a safety risk to me and my family. The dealership has been unable to resolve the problem.

I bought my vehicle almost 2 years ago with 30k miles on it. In December 2025, the car started stalling and wouldn’t run properly. I took it into the dealership and they stated that the engine was burning oil. This was at 90k miles. Hyundai refuses to fix the motor issue because I’m not the original owner. This issue would have started even before the 90k miles because the vehicle had almost used all its oil in between the normal oil change interval. They did a sludge clean and we checked the oil again after 1500 miles and it had already used over a quart of oil.
