Example complaints

“Airbag warning lamp staying on due to a poorly designed sensor system that relies on seat belt buckle and grounding system electrical resistances being incredibly stable over time. This is a design flaw that has been addressed by redesigned seat belt receptacles and replacing wires. If you don't fix this problem, you will never know if you have a real problem with the airbag system, which is obviously a safety issue. If you want to clear this lamp indication, you must shell out $500 to $1500 to do so. …”
NHTSA complaint #10178448, filed 2007-01, 20,000 miles“I have a 1999 Porsche Boxster that had no problems concerning safety, airbag or the seat belts of the car until the air bag light mysteriously turned on. The independent repair shop decoded the code to find the problem is a sensor on the passenger seat belt that is faulty, but the air bag was still working properly. The dealer (rusnak Porsche of pasadena) admitted this was not normal wear and tear, the problem is common, but was not covered since my car was out of warranty. …”
NHTSA complaint #10134376, filed 2005-08“The contact stated the driver and passenger side front seat belts in the vehicle have been replaced twice. On the first incident the passenger side seat belt would come unlocked when the child tugged on it. The dealership replaced the seat belt and the buckle assembly. On 2-01-06 the seat belts wouldn't retract. The dealership replaced the seat belts and the buckle assembly again. Now the seat belt is inoperable.”
