2026 Hyundai Palisade

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!

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.

The contact owns a 2026 Hyundai Palisade. The contact stated that while driving at various speeds, the vehicle went into LIMP Mode and decelerated to 20 MPH. After parking and restarting the vehicle, the failure was self-corrected, and the vehicle operated normally. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 3,000.

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.

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

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.

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 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.
