Inadvertent Seat Belt Unlatch
NHTSA Preliminary Evaluation PE24021 — closed, opened 2024-08-07 and involving the HYUNDAI PALISADE.
NHTSA investigation PE24021 is a Preliminary Evaluation opened on 2024-08-07 and currently closed. The subject of record is HYUNDAI PALISADE, which places this file inside the Office of Defects Investigation queue for HYUNDAI. Latest activity on this investigation was logged on 2025-12-12 — NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
A Preliminary Evaluation like PE24021 is the entry point of the federal defect-investigation process. NHTSA engineers scan complaint databases, field reports, and manufacturer data to decide whether an Engineering Analysis is warranted, whether a voluntary recall is already sufficient, or whether the pattern does not rise to a defect finding.
Investigators summarized the matter as follows: "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 Hyu..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related HYUNDAI files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.
Investigation Summary
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
About This Investigation Type
A Preliminary Evaluation (PE) is the first phase of NHTSA's investigation process. It is opened when the agency identifies a potential safety defect pattern, usually triggered by consumer complaints, manufacturer reports, or field monitoring. During a PE, NHTSA gathers information to determine whether a formal engineering analysis is warranted.
