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.

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 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.

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?

The contact owns a 2026 Hyundai Palisade. The contact stated that on five occasions, while stopped at a light with the Auto START/STOP system activated, the vehicle inadvertently turned off and shifted into park(P) independently. The contact stated that there was an unknown warning light illuminated. The contact attempted to restart the vehicle, and the brake pedal was firm; several attempts were needed to restart the vehicle. The contact stated that on one occasion, while stopped, the Auto START/STOP system failed to activate and the vehicle failed to accelerate as intended; however, the engine was revving unexpectedly. There was a loud clunking sound, and the vehicle jerked and then accelerated as needed. The vehicle was taken to two dealers during the failures; however, the dealer was unable to determine the cause of the failure. The vehicle remained with the second dealer. The manufacturer was notified of the failure. The failure mileage was approximately 1,500.

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.

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.

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.

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.
