NHTSA Investigation PE24021
Preliminary Evaluation · Hyundai Motor America · SEAT BELTS
An investigation is not a finding that a defect exists.
NHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

Inadvertent Seat Belt Unlatch
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.
An investigation is a separate record from a recall and from a manufacturer communication. A manufacturer campaign to repair a safety defect or a failure to meet a federal safety standard.
