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

My car started having the airbag light come off and on randomly the end of January 2026. I caught the first photo February. My car engine shut off the first time March 18. 2026.

When trying to hit drive it tells me the driving conditions aren't met. I shut the car off and back on, everything reset. Contacted hyundai and no codes were stored. My car has now done this same thing the following dates: 6.5, 7.3, 8.4(car went into the shop August 6th-September 3rd). They could not duplicate what I told them, they drove the car 100 miles being mainly freeway miles though I told them its city driving and mainly idle and stopping. I drove my car 3 days and on 9.6.26 it did it twice within 5 minutes. First time on a main road/traffic lights, next in the parking lot I pulled in. Same scenario as above.

I originally brought the vehicle to the dealership for an unrelated infotainment system issue. While driving to the dealership, I noticed that the driver’s seat was rocking/moving, particularly while going downhill. I informed the dealership about the movement and asked them to inspect the seat while the vehicle was there. Upon inspection, the dealership determined that the driver’s seat frame had a weld failure. The vehicle had approximately 42,500 miles at the time. There were no warning lights or dashboard messages indicating a problem with the seat before I noticed the movement. This was not simply a cosmetic or comfort issue. The structural failure allowed the driver’s seat to move during normal vehicle operation. I am concerned that a failed weld in the driver’s seat frame could compromise the stability of the seat during normal driving and potentially during hard braking, an evasive maneuver, or a collision. The defect was identified and documented by the dealership. The vehicle has not been involved in an accident or other event that would explain the seat-frame weld failure. I reported the matter to the manufacturer and a case was opened. I am submitting this complaint because a structural weld failure in a driver’s seat at approximately 42,500 miles raises a safety concern and I believe NHTSA should determine whether similar failures are occurring in other vehicles. The vehicle/failed component can be made available for inspection if requested.

The contact owns a 2021 Hyundai Palisade. The contact stated that while the liftgate was open to retrieve objects from the trunk of the vehicle, the second-row passenger’s side seat collapsed on her disabled daughter. The contact was alerted by her daughter's screams and ran over to the rear passenger’s side to unhook the seat belt and pull her daughter out of the seat, but the seat remained folded. The contact's daughter suffered injuries to her face and hand. Medical attention was received. The failure recurred while the contact and a nurse were placing the contact's daughter in the rear passenger’s seat. The contact stated that the third-row seat also collapsed. The vehicle was taken to the dealer, where unknown recall repairs were performed unrelated to the failure. The contact was informed that there were no recalls associated with the VIN for the seats, and the vehicle was not repaired. The insurance company was notified of the failure and had the vehicle towed for inspection. The insurance company determined that the failure was a manufacturer's defect. The manufacturer was notified of the failure by phone, email, and website, and a case was filed. The manufacturer offered a cash settlement. The failure mileage was approximately 100,000.
