What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The air bags failed to deploy. The contact sustained injuries to the spine, ankles, neck, and right shoulder, which required medical attention. A police report was filed. The vehicle was destroyed and towed. The dealer and manufacturer were not contacted. The failure mileage was 70,000.
The contact stated that while driving at approximately 55 mph, she crashed into a ditch resulting in the seat belt separating from the buckle. The vehicle was towed to a dealer where it was diagnosed that the tensioner assembly needed to be replaced. The vehicle was not repaired. A police report was not filed.
The air bags did not deploy; instead, I received an "airbag fault" light and audible signal and the car filled with black smoke. Thankfully, no one was injured in the accident. But if it had been a head-on collision and the air bags failed, I may not be here today to type this safety complaint.
I had my seatbelt on but was injured also. Had my airbags deployed the way they are supposed to, these injuries may not have occurred at all. I now have a car that is more than likely totaled and hospital bills where we went to see a doctor the next day.
Roughly 2 years later (July/August 2023, about 104,000 miles), my low-beam headlights didn't function at ignition one day. Obviously, lacking headlights is a core safety issue. I learned that the low-beams also use ground point G102.
It's scary to think that these door latches can fail so easily. Other body parts for this vehicle are becoming increasingly difficult to locate.
Door latches goes out on vehicles and the door don't stay shut. The door will flap open will driving, have to use a seat belt around the inside handle and then connect to the seat buckle to keep door close. I have 2 g8s that these have failed on.
Tl* the contact owns a 2009 pontiac g8. The contact stated that the rear brake lights remained illuminated. Buick, gmc, cadillac donovan auto & truck center ([address], wichita, [ZIP], [phone]) was notified of the failure, but had not diagnosed the vehicle.
