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.
As a result, the contact crashed into the median strip and the air bags failed to deploy. A police report was filed and there were no injuries reported. The vehicle was destroyed and towed to an independent mechanic.
Tl* the contact owns a 2008 pontiac g8. While driving approximately 50 mph around a curve, the steering wheel seized and caused the vehicle to crash into a tree. The air bags deployed. A police report was not filed. The contact sustained a cut around the left eye which required medical attention.
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.

What to check before buying

- Electrical system. Scan all modules, test the battery and alternator, inspect connectors near the impact zone.
- Suspension. Wheel alignment, control arms, subframe, even tire wear.
- Powertrain. Shift quality under load, harsh shifts, transmission codes, CV joints.
