| Air Bag problems |
I own a 2022 Porsche Cayenne. The vehicle intermittently displays a red “occupant seat belt not fastened – fasten seat belt” warning and sounds the seat belt warning chime while the front passenger seat is completely unoccupied and nothing is placed on the seat. This problem first began intermittently in approximately 2025 and has continued to occur. In September and October, 2026, the problem occurred again for over one week now while I was driving. The front passenger seat was completely empty, but the vehicle indicated that an occupant was present and needed to fasten the seat belt. I photographed the instrument cluster while the warning was active. I am concerned that the vehicle may be incorrectly detecting the occupancy status of the front passenger seat or may have a malfunction in the passenger seat belt/occupant restraint system. Because passenger occupancy information may be used by the vehicle’s restraint and air bag systems, I am concerned about whether the vehicle can correctly determine passenger occupancy and provide the appropriate restraint protection in a crash. The problem was intermittent, which makes it difficult to reproduce consistently until very recently. The vehicle is available for inspection. Porsche has issued technical information concerning “occupant seat belt not fastened” warnings on Cayenne vehicles, but to my knowledge my vehicle is not currently covered by a recall for this condition. The manufacturer warranty has expired, although this intermittent problem began before the warranty expired. I am requesting that NHTSA evaluate whether this condition may represent a safety-related defect affecting 2022 Porsche Cayenne vehicles or other similarly equipped Cayenne vehicles.
