Power Train Problems of Hyundai Palisade - part 1

"stop vehicle and check power supply" warning lights accompanied and panic alarm goes off on new 2027 Palisade hybrid calligraphy with 72 miles. The passenger rear brake grabs much more than the others which you can barely feel. Johnson hyundia of apex,nc, where we purchased the vehicle tell us not to bother bringing it to them because unless it has a fault code or constant message, they can't do anything. Hyundia corporate gave me a case number but acted like they never heard of it happening to anyone else. Reddit posts have at least 20 other cases of this same thing happening to new hybrid vehicles.

My car makes a clunking noise in the rear (rear differential) while starting/ stopping at slow speeds or turning a corner. No warning lights but it seems to be worse. Dealership has replaced shock absorber assembly and said it corrected it. It did not. I have called the dealership again for them to tell me my car needed a system update.

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.

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.

My Palisade is burning oil at a rapid pace. I took it to the dealership and they said it was an acceptable level. I don't believe that to be correct. I have less than 100,000 miles on it.

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.

Two simultaenous problems happened: 1) loud clunking/thudding during low-speed turn. 2) clunking/knocking/rattling noise from suspensions when going through uneven grounds. This both things happened before 20,000 miles. Had awd coupling and rear differential unit replaced under warranty regarding problem 1). Had rear shocks replaced under warranty regarding problem 2). Found there has bben TSB issued related to 2), for older models, TSB 25-ss-004h but not for this year of models. Those two exact problems started again at about 40,000 miles. Had vehicle checked at 50,500 miles recently. Regarding problem 1), the dearship found issue with awd coupling, stating faulty parts, drive shaft seal was 1/8" off and materials are fused. Replaced awe coupling, and ecu program update. After program update, I do not see the power distribution monitor anymore from my dash. The program update should turned it off for some reason that I do not know. I have no clue that awd module is working normal as I cannot see the power distribution action anymore. Regarding problem 2), they replaced both rear shocks again. The problem went away for now. This vehicle has been only 50,000 miles and had 4 major issues (2 times of two major identical issues) that alongside with many owners' compaints, and seems highly related to one of technical service bulletin that was previously issued for older models. I would like to request investigation on these services.

I am reporting multiple recurring safety concerns with my 2026 Hyundai Palisade. Loss of acceleration: under heavy throttle, the engine revs to approximately 5,000 rpm but the vehicle does not accelerate as expected. This has occurred repeatedly and appears more likely after the vehicle reaches normal operating temperature. During one incident on the highway, I needed to accelerate quickly to avoid surrounding traffic, but the vehicle did not respond as expected, creating a potential safety risk. An authorized Hyundai dealership inspected the vehicle and reset the transmission adaptive values, but the condition remains. Lane keeping assistance: the lane keeping assistance system consistently positions the vehicle toward the left side of the lane instead of properly centering it. The issue has been reported to the dealer, but the condition remains unresolved. Power second-row seat: the power second-row captain’s chair can continue moving while folding, creating a hand-crush hazard if a person’s hand is in the path of the seat. It also interferes with proper third-row seat operation. This issue has been reported to the dealer and remains unresolved. These issues have been reported to Hyundai and remain unresolved after dealer inspections. The vehicle is available for inspection, and I have documentation and video evidence of the acceleration concern.

Safety-critical shifter system malfunction - I am experiencing a recurring and serious shift system defect with my 2026 Hyundai Palisade calligraphy. The issue first occurred within the first 500 miles of ownership, shortly after purchasing the vehicle new. At that time, the vehicle required diagnosis and repair by the dealership and remained out of service for nearly one month. Despite that repair, the same or a very similar issue has now returned. The vehicle displays a "shifter system malfunction – service immediately" warning and does not allow me to change gears while the vehicle is running. The gear selector becomes unresponsive, and the only way to restore functionality is to shut the vehicle off and restart it. After restarting, the vehicle often engages with a loud thud/clunk and significant vibration that can be felt throughout the vehicle. This creates serious concerns about the safety, reliability, and overall integrity of the drivetrain and shift-by-wire system.

Cylinder 1 and 6 rod bearing failure, plus complete destruction of piston number 6. On highway engine failed, sudden loss of power to move vehicle.

2026 Hyundai Palisade sel 8p awd. Brake pedal sinks to floor when depressed while vehicle is in motion, causing vehicle to glide before stopping. Defect first noticed June 1, 2026 and confirmed June 2, 2026 at approximately 530 miles during a 34-mile round trip with consistent repeated occurrence at both low and moderate speeds. Vehicle returned to dealership for diagnosis. Dealership declared unable to duplicate. No diagnostic trouble codes found. Hyundai engineering was consulted by dealership. This is a second serious defect on this vehicle — a full transmission assembly replacement was performed under warranty in may 2026 within 4 days of delivery and approximately 259 miles of personal use. Hyundai motor America lemon law re-evaluation currently in progress.

Premature engine fail. Excessive oil consumption due to piston ring failure. Maintenance has been done on car on regular basis. No check engine light. Carson was services at dealership 4 months ago.

We lease a 2026 Palisade with only 4k miles. Several weeks ago I was going through a toll plaza, car would not accelerate after slowing down, as if it was in neutral. All of a sudden it kicked into gear and car lunged forward. 10 min later at a traffic light car failed to accelerate after a complete stop. Press the accelerator sluggish response, then kicked back into gear. Very scary. I pulled over and notified the dealer. Then set an appoint. Dealer did a diagnostic, found no issues, could not replicate problem on test drive . Everything was fine a few weeks. My son took the car. Had the same exact issue with vehicle not accelerating. Then kicked into gear really hard and vibrating. This was scary for him because he was in a parking lot. Luckily there was no accident as a result. However, this time an error code (check engine light) came on and the Hyundai app showed a dtc code- p001600 (powertrain / engine). Car was immediately taken to dealer on may 28th 2026. It is now Jun 11th. Still no time frame for fix. The think it a software issue and Hyundai is still "working" on a solution.

Following a dealer transfer assembly replacement under warranty on a 2025 Hyundai Palisade, technicians failed to perform a post-repair alignment and left the driveshaft unseated. The 2nd dealership we went to subsequently misdiagnosed the resulting suspension warping as 'tire overinflation' on June 5. As a direct result, my family unknowingly drove thousands of highway miles across state lines to mt and sd with an unseated drivetrain and a completely loose structural subframe bolt, presenting a severe risk of catastrophic suspension/steering failure at highway speeds. They misdiagnosed 3 times and claimed to do test drives each time, but each time we got in the vehicle, we heard the noises, they said they could not hear. Had a mechanic ride with to verify the noise, and only diagnosed the driveshaft unseated afterward, but not the subframe bolt, which the structural defect was finally confirmed on August 25, the 4th time at the 2nd dealer.

I recently purchased this vehicle, and shortly after, it began having serious powertrain issues. When I accelerate, the vehicle intermittently loses power and starts shaking violently. It feels like the engine or transmission is slipping or failing. The rpms surge and drop rapidly, and the vehicle hesitates, jerks, and sometimes briefly slows down before suddenly accelerating again. This creates an unsafe and unpredictable driving condition, especially when merging or driving in traffic. I’m concerned about a loss of propulsion while the vehicle is in motion. My mechanic indicated the issue may involve the torque converter clutch not engaging properly (possible “stuck off” or circuit performance issue), which would explain the shuddering and inconsistent power transfer. Despite how severe this is, there are no warning lights or check engine light, and no diagnostic codes, which raises concern that the failure is not being detected by the vehicle’s onboard systems. I am also experiencing low and fluctuating engine oil levels even after topping it off and a recent oil change, which may indicate an additional engine-related defect. The vehicle has a clean title and no accident history. - failed system: powertrain (engine/transmission), suspected torque converter clutch malfunction. Vehicle is available for inspection. - safety risk: intermittent loss of power, hesitation, and surging creates a high risk of collision, especially in traffic or at highway speeds. - confirmation: my independent mechanic has identified as likely a torque converter related issue. - inspection status: not yet inspected by manufacturer or insurance. - warnings/symptoms: no warning lights or codes. Symptoms began shortly after I purchased and have worsened over time.

On April 17, 2026, while driving my 2022 Hyundai Palisade with approximately 167,000 miles, the vehicle suddenly lost engine power and was unable to maintain normal driving speed. The sudden loss of propulsion created a safety risk because the vehicle could no longer operate normally in traffic. I was able to move the vehicle out of traffic, but it would not restart. I also observed white smoke coming from the engine compartment. The vehicle was towed to matt bowers Hyundai slidell, an authorized Hyundai dealership, where it remains and is available for inspection upon request. The dealership has inspected the vehicle and advised that the engine needs to be replaced. The exact internal component that failed and the final cause of the engine failure remain under review by Hyundai. I do not recall any warning lamps or messages before the sudden failure. The timing of any prior symptoms is unknown. The vehicle had been maintained through authorized Hyundai dealerships. On December 29, 2025, a Hyundai dealership replaced the oil filter housing because of an oil leak and performed a synthetic oil and oil filter change. On March 11, 2026, approximately five weeks before the failure, the dealership performed another oil and oil-filter change and a multipoint inspection. I am reporting this incident because the sudden loss of engine power while driving, the inability to restart, and the smoke from the engine compartment created a serious safety concern. The vehicle remains disabled and available for further inspection.

My car is misfiring. It will not accelerate as it should. It is like bogging down unable to accelerate when it needs to. It’s struggling. Hyundai is aware of the issue and making owners drive regardless while they “wait for a fix”. It’s extremely dangerous. I’ve almost been hit several times trying to merge onto a highway because it will not accelerate. I’ve had total loss of power one time, putting me and my infant in extreme danger. This has been happening since April.

I own a 2021 Hyundai Palisade and have experienced a complete transmission failure that I believe Hyundai had prior knowledge of and failed to address. Before my warranty expired, I contacted the dealership several times to report transmission symptoms I was experiencing. I was told that because no diagnostic code had been produced at that time, there was nothing they could do. Eventually, my check engine light came on with a p0741 code — torque converter clutch circuit performance. When I brought the vehicle in, the dealer flushed the transmission fluid, which came out dark and contaminated with metal particles. After running the vehicle, the fluid was still dark, indicating active internal damage already in progress. The dealership has now told me I need a full transmission replacement at my own expense. I am the second owner of this vehicle with approximately 105,000 miles. I have since learned that Hyundai issued technical service bulletin #20-at-005h-1 specifically addressing the p0741 code on the 2021 Palisade, instructing dealers to replace the solenoid and valve body harness. This repair procedure was never applied to my vehicle despite my early report of symptoms. I believe this is a known defect that Hyundai has failed to escalate to a recall, leaving consumers like me with thousands of dollars in repair costs for a problem the manufacturer was already aware of. I am requesting that NHTSA investigate this issue and consider whether a recall is warranted for the 2021 Hyundai Palisade.

After emissions campaign 9c9, downshifting using paddle shifters on downhill grades, engine failing to maintain speed. Does not slow car down like it did before, seems like no compression. Fuel efficiency / emissions over traditional transmission braking, forcing drivers to use brakes more often to avoid high rpms. Safety risk: the lack of engine braking can lead to brake overheating or fade on long downgrades, lack of engine braking can lead to brake overheating or fade on long downgrades. Above is what google found [xxx] ) when I put in some key words. Here is what I wrote to a [xxx] . My 2021 Hyundai Palisade campaign 9c in your article about the 2022 having the same downshifting issues after the emissions recall was done. Have you heard from other 2021 owners? I use the downshift for breaking/keeping my speed down to save the breaks here in the [xxx] , [xxx] , and [xxx] mountains. Does not function as designed. "loss of engine braking" " high engine revving" did go back to dealer and drove tech around lot. I called back later and nothing they can do. 5/12/26 went to the dealer again, for an appointment. Dealer service manager said it working as designed. Bull, was not that way before. He said if I don't like it, trade in the car. . He also said that I can't compare the palasade to the other cars that have manual shifting. Bull. I said why have them if they don't do anything. . . Tried to explain that I have been driving for over 40 years and have always downshifted every car. This was fine until the emissions recall. Got no place with the dealer. Contacted Hyundai corporate last week, and they should be following up on Wednesday/tomorrow. 5/13/26 left vm for sales gm at bowser today where I purchase the car. Wrote above and more [xxx] contacting you now. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

In March had issues with driver and passenger seats not moving up and down without getting stuck have to mess with it for awhile to move up or down and sometimes won't go to a directions it can move to seat even though setting it in a certain position every time turn off car and start goes to a position to high up in a way can't get in till you put it down then get in car when moving the 2nd row seat the passenger seat moved front back instead then folding seats 2,3rd row not working correctly found out mid Mar recall 2,3rd row folding issues child died, 3rd row seat belts called corp said do not allow passenger in 2nd, 3rd row till fixed called service said no fix so had wait week later car was hesitating when push gas engine power train warning light came on tow car to dealership they lied proof in writing they lied said fix the seats even though at that time no fix for recalls only reset engine light even though car was giving issues almost broke down they had car 8 day made me pick up car said was fixed proof it wasn't they threaten harassed me to get it I said recalls show on NHTSA still till off not fixed won't come so they said day I had bring loaner car back or they come repo it they removed it from NHTSA site that day said see it's off I said there no way if no fix yet recalls I called many service dept ask went on Hyundai corp main site said fix for seat belt mid may this was April 7 and I ask them to put in writing several times car safe for my 3 yr old grandson they never once say car safe they illegally fraud took recall off the site all to get me come get car got car seats not fixed they said in writing seat belt fixed with tape tape? they put on NHTSA recalls after got car I confronted them then they removed again to not get in trouble to take off then on. But no seats fixed and could not put passenger car barely drove car was still hesitating gas ac loos power not even month later engine light power train issue again but not just light defect cause.

The vehicle suffered a structural "seam leak" on the pressurized oil filter housing. This was verified by an authorized Hyundai dealer (dealer xxx, invoice #xxx). The failure is a structural crack in the housing component itself, not a maintenance-related seal or filter failure. This defect causes pressurized engine oil to spray directly onto the hot engine block while the vehicle is in operation, creating a severe and immediate fire hazard. Additionally, the rapid loss of oil and oil pressure poses a risk of sudden engine seizure or stalling at highway speeds, which could lead to a crash. Despite being a known manufacturing defect in a critical engine component, the manufacturer has refused to address the safety implications or offer a remedy. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I am reporting a recurring safety issue with my 2026 Hyundai Palisade calligraphy involving severe shaking, sputtering, loss of acceleration/power, stalling, and abnormal drivetrain behavior. The first incident occurred at just under 10,000 miles after driving for approximately one hour. While traveling at highway speeds, the vehicle began shaking severely and lost significant acceleration/power. After exiting the highway and stopping, the vehicle shut off. When restarted, it continued shaking and would not accelerate normally. No warning lights appeared. The dealership reported multiple stored fault codes, including transmission-related codes. The codes were reset and the vehicle was returned to me. The same condition later occurred again after extended driving. The vehicle shook severely and lost acceleration, again without warning lights. After being turned off for approximately five minutes and restarted, the symptoms temporarily disappeared. The vehicle has since undergone multiple repair attempts. Hyundai/dealership technicians replaced the flywheel. After that repair, the vehicle developed new shaking/stuttering during startup and shutdown. The vehicle was returned again and a motor mount was repaired/replaced. Two days after receiving the vehicle back from the latest repair, it is now exhibiting another serious drivability issue and appears to remain in first gear or otherwise fails to shift normally. I have video of the severe shaking. A dealership technician also advised me that multiple other 2026 Palisades at that dealership were experiencing similar issues and Hyundai had not determined the underlying cause. I am concerned the vehicle may unexpectedly lose propulsion, stall, or fail to accelerate in traffic or at highway speeds. Multiple repair attempts have not resolved the safety concern. The system will not allow me to upload the videos I have, but you may contact me for them.

We had two incidences with in a week. 1. My wife was at a stop light getting ready to go through an intersection when the light turned green she pressed on the gas pedal and the vehicle would not go it just flashed a few codes and a warning came up about a possible condition that occurred. She had to place the vehicle in park shut it off start it up again and put it into drive mode in order to get going again all this while in traffic. We made an appointment with Hyundai of anchorage but they couldnt find a problem they updated the soft ware and gave the car back to us. 2. The second time it did this was about a week later. My wife went shopping and got into the car to leave, she started the car and put it into gear and it would not move when giving it gas it flashed some more codes at that point she called me. I restarted the vehicle got it moving and when I came to a stoplight with five vehicles ahead of me the light finally turned green vehicles started moving but when I went to move the car would not go and there was a vehicle behind me a ways back that was approaching rather fast. As my wife did before I had to shut the vehicle off restart it and put it in drive in order to go.

Seats still don't work after recall fix on 2nd and 3rd row. Front seats also do not work when moving 2nd row seat front to back front seat moved instead. Power train engine issues been in Hyundai service 3 times diff services depts and still not fixed have not been able to drive car since Mar due to these issues. Engine light on 3 power train warning codes on. When pushing gas car hesitates and almost completely stops on freeway or on only 2 way highway making it very unsafe to drive. Loos of power to ac and lights due to this issue!.

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.

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.

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.

The contact owns a 2025 Hyundai Palisade. The contact stated that while attempting to come to a complete stop, the transmission unexpectedly upshifted to accelerate independently. While depressing the accelerator pedal, the vehicle failed to respond as needed. No warning light was illuminated. The vehicle was taken to the dealer to be diagnosed; however, the result was unknown. The vehicle was not repaired. The failure had occurred on sever occasions. The manufacturer was not notified of the failure. The approximate failure mileage was 816.

The vehicle has two open safety recalls. Recall 26v034000 – the vehicle does not meet federal motor vehicle safety standard no. 226 for ejection mitigation. There is currently no remedy available. Recall 25v607000 – seat belt buckle may not latch properly, increasing the risk of injury in a crash. The vehicle also had a powertrain fault that triggered the check engine light and it has been at the dealership for more than 30 days for I am concerned about the safety of my famil.

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.

I am reporting a recurring, life-threatening electronic failure in my 2023 Hyundai Palisade. On [xxx], while turning into an intersection, the vehicle's brakes spontaneously engaged, stalling the car in the path of oncoming traffic. During this event, multiple critical safety systems failed simultaneously, including the headlights and horn, leaving me unable to warn other drivers. A "violent" surge was required to clear the intersection, risking a high-speed collision. Similar spontaneous recurrences occurred on [xxx] and [xxx], and most recently on [xxx]. These incidents are characterized by "phantom braking," total loss of propulsion, and a complete lack of interior/exterior electronic response. Technical evidence: diagnostic scans revealed 16 distinct fault codes (including c161608, c181287, and u012687) involving the chassis control module, electronic control unit (ecu), and communication buses. Despite these logged codes, Hyundai and the dealership have repeatedly returned the vehicle to me, stating they "cannot replicate" the issue, thereby dismissing a documented electronic record of failure. Arbitration status: I entered into bbb auto line arbitration (case #[xxx]). Hyundai has contested the claim by attempting to manipulate the "start date" of the defect to February 2024 to avoid lemon law statutes, despite dealer records confirming the first occurrence in August 2023. As of January 13, 2026, the dealership is again attempting to force me to take delivery of the unrepaired vehicle. This vehicle is a "phantom" safety hazard. The manufacturer’s inability to replicate a logged electronic fault during a brief test drive does not mitigate the extreme risk of sudden braking and power loss at highway speeds. I am requesting a formal investigation into these specific fault codes and the electronic integrity of this model. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

In compliance with the safety recall issued for my vehicle regarding the defective seat belts, I brought my vehicle in to vision Hyundai, canandaigua, NY for the recall work to be completed. Upon the service department's investigation of the seat belt components, they discovered further issues with it, beyond what was initially identified under the recall. Service department advises that it will take minimum of 1 month to obtain parts and make repairs. Service department issued a compact SUV which is not capable of safely installing my child car seat, or carrying the number of passengers which my affected vehicle does, putting a strain on our family's routine needs. Additionally, the affected vehicle was brought into the shop to address a powertrain issue where the vehicle loses all power and will not accelerate over 20mph, posing a serious safety concern. Hyundai has not provided any update on this or how it will be handled.
