What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I was on garden state parkway and hit a deer , all the smoke came out but my air bags didn't deploy and my car was totalled. I'm getting no response from dealer or anybody.
Check engine light recently came on, car completely lost power and turned off during as I turned right at a light, had onstar run diagnostics, code involved the emissions system, was advised to fill up with high quality fuel, and drive with the gas cap off to correct it.
A deer ran out in front of my vehicle while going 70 miles per hour, the seatbelts engaged so hard that it snapped the back of my driver seat however the air bags did not release. The air bag signal for the passenger and the driver sides came on but the air bags never deployed. Pictures attached.
The passenger airbag warning light is illuminated, and I am uncertain about its proper deployment in a critical situation. The issue remains unverified by a dealership or any other individual. The component has not been subject to any inspection. I do not recall the specific warning message displayed on the dashboard.
Transmission torque converter shuddered and did not stop after service. Had to replace entire transmission for $5870.68 repair bill.
Jerking while picking up speed, key fob keep saying not detected, Radio feature work but stuck to basic screen I guess electrical problem Brakes is very rough not sure
Blind spot detector is causing the driver interface to display false alarms
It would happen a couple of more times until one day I was trying to go home from work and I saw a message indicating something along the lines of “Service: Power steering” followed by the same symptoms.
