Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Airbag light turn on, on my dashboard, I checked it with a professional OBD2 scanner and shows a code which indicates a fault in the Occupant Detection System (ODS), which the scanner says it is very common for my vehicle. This puts my passengers at risk due to an airbag system fault. My vehicle has not been in an accident, nor has my passenger seat been messed with. I have spoken to other individuals with the same vehicle, also checked the forums for my specific vehicle and almost all of them have the same issue with the ODS, with no recalls or warranty resolution from the dealership. …”
NHTSA complaint #11691027, filed 2025-10“The airbag passenger light is illuminated causing air bag system to remain off until resolve. The vehicle was taken in for inspection and dealer confirmed diagnostic results found Occupant sensor malfunctioning. Under warranty, the sensor was covered, but after installation the system also found that wasn’t the only thing to replace. It’s a handful of sensors and harness that is integrated within the seat frame with the ONLY solution to replace the entire chair/seat frame. This item does not fall under warranty. My concern is the safety of my family riding in the vehicle. …”
