2020 Hyundai Palisade

On August 7, 2024, the Office of Defects Investigation (ODI) opened PE24021 to investigate complaints alleging inadvertent unlatching of seat belts in model year (MY) 2020-2023 Hyundai Palisade vehicles manufactured by Hyundai Motor America. The complaints alleged that, without warning, the seat belts sometimes inadvertently unlatch, increasing the risk of injury due to full loss of seat belt protection in the event of a crash. As a result of information exchanged as part of the investigation, on April 3, 2025, Hyundai initiated a warranty extension policy for seat belt buckles on model year 2020-2025 Palisade vehicles in the U.S. and Canada.  Hyundai subsequently initiated a request for warranty parts returns to support further analysis by the buckle supplier, ZF Lifetec. The warranty extension (reference “Z06”) noted that certain 2020 – 2025 model year Palisade vehicles may experience abnormal seat belt buckle(s) operation.   Hyundai extended the warranty coverage for the seat belt buckle under this condition to 15 years/150,000 miles (whichever occurs first) from the date of original retail delivery or date of first use.  This action is valid for original and subsequent owners. On September 11, 2025, Hyundai filed recall 25V-607 for certain 2020-2025 Hyundai Palisade vehicles.  Hyundai explained in its recall filing that the subject vehicles are equipped with seat belt buckle assemblies in the front row and second row outer seating positions that may contain out-of-specification components manufactured by the supplier.  These components can cause interference within the latch channel, potentially increasing friction, particularly under cold ambient temperatures. Improperly produced seat belt buckles, combined with slow insertion of the seat belt tongue plate, may prevent the seat belt buckle from fully latching. The recall remedy is currently under development. In view of Hyundai’s recall action, ODI is closing this Preliminary Evaluation, but will continue to monitor the issue as a remedy is developed and implemented. ODI will take additional action if warranted by future circumstances. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

Hyundai Motor America has been notified of the safety issue through the Mississippi Attorney General’s Office, which required Hyundai to provide a written response within ten business days. Hyundai has not responded to the Attorney General, has not responded to follow‑up attempts, and has not provided any guidance or corrective action. The local dealership reports that Hyundai Corporate will not authorize warranty diagnostics or repairs, leaving the vehicle in an unsafe condition with no manufacturer support.

On or about XXX I brought my vehicle into the dealership as my 2020 Hyundai palisade suffered a severe, sudden engine malfunction while driving at highway speeds. The vehicle began shaking violently, losing power, and making loud mechanical noises forcing me to navigate dangerous highway traffic to get it to the dealership. Prior to the failure, in XXX, the vehicle was brought into an authorized dealership as the vehicle would not drive properly, very slow acceleration and the vehicle feeling like it was stalling causing a danger to the road. . The dealership performed an inspection on the vehicle and diagnosed "carbon buildup due to mileage and age," they performed an authorized emissions software update, changed the oil, and performed a paid fuel injection cleaning. The dealership did not issue a safety warning or advise against driving the vehicle long distance back to [XXX]. A few months after this service, the vehicle suffered total engine failure. Professional teardown of the Hyundai Lambbda ll V6 engine show that unresolved carbon buildup and software defects lead to piston ring failure, severe misfires, oil starvation, and sudden loss not motive power. Operating a vehicle experiencing severe mechanical shaking and power loss at highway speeds poses an immediate risk of an accident.

When attempting to use engine braking to control descent on mountain roads, the vehicle failed to slow. Engine RPMs increased and speed increased requiring significant brake usage. Last year the vehicle performed as expected as deceleration was controlled via downshifting with much less brake usage. The only change was the application earlier this year of Hyundai service campaign 9C9.

The contact owns a 2020 Hyundai Palisade. The contact received notification of NHTSA Campaign Number: 25V607000 (Seat Belts). The contact stated that while parked on several occasions, the second-row driver-side and passenger-side seat belts buckles failed to latch and required three to four attempts to latch securely. The vehicle was taken to a dealer, where it was determined that an object might be stuck in the buckle assembly, and the seat belt buckle assembly needed to be replaced. The vehicle was repaired, but the failure recurred approximately a week later. The manufacturer was notified of the failure. The failure mileage was approximately 25,000.

The vehicle suffers from a severe manufacturing defect causing excessive engine oil consumption (burning more than 2+ quarts per 1,000 miles) with no warning lights or oil pressure indicators activating. With little to no warning, I could be driving and experience catastrophic engine failure. This defect creates an immediate safety hazard, as sudden engine seizure or stalling at highway speeds risks loss of power braking and steering, creating an imminent risk of a high-speed collision. The dealership has confirmed the oil consumption issue after we noticed the vehicle stalling and performing sluggishly until the oil was changed.
