Selected complaints filed with NHTSA by 2007 Chevrolet Trailblazer owners, lightly cleaned up (personal details are redacted by NHTSA).
SERVICE AIRBAG light came on last week. Took vehicle to dealership to fix. Parts are discontinued so airbag cannot be fixed per Ferman Chevrolet dealership. Also told me that airbag will not work if in an accident.
Takata recall I was involved in an accident that did over $9,000 damage to my front end of vehicle. The airbags did not inflate. This was on a city street, and both vehicles were moving. Also had a power window motor go out. I understand that this might be involved in a recall of window motors that could be causing fires.
A vehicle was stopped in front of me and I rear ended them. I was going around 44-55 MPH. After I hit the other car from behind I crossed 2 lanes of traffic and went thru a pretty deep ditch. The air bags did not deploy at all. I sustained a concussion., several head lacerations and a fractured lumbar spine.
I had my cruise set on 55 MPH and was hit head on by vw jetta pulling out toward my vehicle, then forced to left into a telephone pole. Airbags didn't deploy, and received broken sternum. Don't know if seatbelt injured me, or if the seatbelt didn't lock on 2nd impact and possibly hit the steering wheel.
Swerved to avoid hitting a deer almost hit mailboxes so swerved to avoid them. I swerved to much than in my correction hit the gas instead of the brake. I than hit a tree between 45 - 50 MPH. My airbags never deployed.
My husband was driving about 40 MPH on a country paved road when his side airbags went off. His radio and lights started flashing. He was able to get home the mile or so, parked the car and shut it off. When he went to start it the next day nothing worked. He was startled by this happening and was lucky he didn't cause an accident or get hurt. He could have caused an accident very easily due to the visibility. Not sure what caused this to happen. - unknown the vehicle was taken to a Chevy dealer but they were not able to diagnosis it so at this point we are not aware of exactly all that was effected with the vehicle. I have attached the denial from our insurance.
On 9/24/08 I was involved in an auto accident where my 2007 Chevrolet Trailblazer's airbags failed to deploy. My vehicle impacted another with my entire front end at approximately 45 MPH. My Trailblazer was totaled. Not only did my airbags fail to deploy, the OnStar system did not automatically go off. I had to hit the button to summon assistance. When we asked the dealer about it, their response was "sometimes they go off, sometimes they don't" I sustained a broken left arm, numerous bruises, a cut on my ankle and an ankle sprain. I also injured my back and neck which is requiring ongoing care.
