2024 Hyundai Palisade

Component/System: Engine — specifically the engine valve springs and related components. Description of what happened: While driving, the vehicle began to shake violently, and the check engine light came on. At times, the vehicle loses power and shuts off completely, then restarts and drives normally for a short period before the issue returns. It feels and sounds like the engine is about to fall out. These symptoms match the description in Hyundai Safety Recall 255 for the 2024 Palisade (fractured engine valve springs that can cause engine failure, loss of power, and fire risk). Safety risk: The sudden loss of power and engine shaking put my safety and the safety of others at risk, especially while driving in traffic or at higher speeds. The problem could lead to a crash or engine fire if the valve springs fracture or the engine block is damaged. Inspection/confirmation: The problem has not yet been officially confirmed by a dealer, but Hyundai stated that my VIN is not included in the recall, even though my vehicle shows the same symptoms and falls within the recall’s production timeframe. Prior warnings or messages: The check engine light comes on when the vehicle starts shaking, then goes off after the vehicle stops or restarts. The issue has occurred multiple times, most recently in early October 2025. Additional notes: The vehicle is a 2024 Hyundai Palisade, and the issue began about 5 days ago. The symptoms are consistent with fractured valve springs as described in the recall. I am requesting investigation and inclusion of my VIN in this recall.

It was a sunny day with no water around and I was pulling up to a signal and decide to put brakes on and the car didn’t break right away, instead the car slide for at least 10 ft before it came to a stop. This incident wasn’t the first one and has happened in exact same manner at least 3 times. All the times it has scared the driver as the driver doesn’t know if the brake feature works and when this happens the vehicle drags several feet before coming to a stop.

This vehicle has driver-assist functions and warning lamps in the electronic instrument cluster located in the driver's display area. Randomly and unpredictably a group of warning lights -- "check blind spot" collision alarm, lane safety indicator light, triangle-shaped general alert icon -- all activate simultaneously for no apparent reason. The unpredictability creates a serious distraction to the driver and potentially unsafe reactions which could result in damages and injuries. There are numerous references to this problem on the internet, indicating this is a widespread safety issue for Hyundai models. Dealer said possible recall imminent.

Over the course of 6 mos. I've experienced several instances while braking on uneven surfaces, wherein the ABS system of my 2024 Hyundai Palisade reacted surprisingly very unpredictably. On 2 occasions this caused a near-miss; one of which involved braking while turning a corner on a rough surface and the car skidded/skipped (wheel-hopped) unpredictably. In another near-miss, I quickly released/reapplied the brakes which seemed to deactivate this erratic ABS behavior. My vehicle was recently shopped at my local is Hyundai dealership for routine maintenance/defects. This ABS malfunction was also to be addressed. The dealership reported to me that they were unable to duplicate, the car was operating as intended, no trouble found...Of course, I was highly. unsatisfied with this response, particularly after having taken a test drive with the service department supervisor, demonstrating the issue while driving and reviewing relevant online forum discussions that documented the exact issue I've been experiencing. PLEASE HELP BY DEMANDING HYUNDAI IS IMMEDIATELY ADDRESS THIS LIFE THREATENING ABS SAFETY DEFECT BY MEANS OF AN URGENT RECALL! Thank you.

The sunroof glass appears to have exploded or burst open. The vehicle was parked at the time of the incident. The owner had driven the vehicle just two hours prior and returned to it to find that the sunroof had burst upwards sending glass on top of the remain parts of the sunroof and all over the interior cabin. There was no projectile involved and the remaining glass around the hole was protruding upwards indicating it had been pushed upwards by the pressure. This could have happened while occupants were in the vehicle. The vehicle has been inspected by the dealer who could not find anything wrong with the frame or housing to indicate a defect.

Vehicle Safety Concern - Unintended Vehicle Movement Vehicle Information: 2024 Hyundai Palisade Incident Date: XXXXXXX Location: Commissary parking lot in [XXX] Incident Description: On XXXXXXX my wife parked our Hyundai Palisade in a designated parking space at the commissary. She properly engaged the parking gear selection and turned off the engine. After opening the rear hatch to retrieve shopping bags and securely closing it, she proceeded into the commissary to shop. Upon returning approximately 15 minutes later, she discovered the vehicle was no longer in its original parking position. The Palisade had rolled away from where it was parked and collided with a parked 2018 Toyota Sienna, resulting in property damage to both vehicles. Actions Taken: Due to concerns about a potential mechanical defect that may have caused this unintended vehicle movement, we immediately contacted Hyundai customer service. We have since scheduled and completed diagnostic inspections at two separate Hyundai dealerships. Both dealerships performed comprehensive diagnostics but reported finding no mechanical issues. Safety Concerns: This incident represents a significant safety hazard. The unintended movement of our vehicle in a parking lot could have resulted in serious injury to pedestrians or other motorists. We are deeply concerned about the potential for this incident to recur and cause harm to others. Request for Investigation: We respectfully request that NHTSA investigate this matter to determine if there is a systemic safety defect in the Hyundai Palisade that could cause unintended vehicle movement when properly parked. We believe this incident warrants investigation to protect public safety. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When braking on an off ramp, the vehicle began to shudder. The steering wheel and brake pedal were shuddering as well. The vehicle came to slower stop than usual almost causing us to rear end the vehicle in front of us. This has happened prior on uneven roads when slowing/coming to a stop. The dealership does not have an answer and couldn’t reproduce it
