There were no sudden abrupt maneuvers, no contact with any other objects . . . Nothing!!!! it appears that this is a common problem with nothing being done about it . . . Why???!!!.

7 Air Bag problem

Failure Date: 05/18/2013

Driving at 45mph and hit a pothole, both side curtain air bags deployed. Took to dealer and the tech said there is no damage to tires, wheels or suspension so that just doesn't happen. It will have to be an insurance claim because you were driving at the time. Talked to the service manager and he said there are scuffs on the tires and rims and it was enough jolt to set off the airbags so they were working as designed. It will have to be an insurance claim.

8 Air Bag problem

Failure Date: 08/27/2012

Driving at posted speed limit, both side curtain airbags deployed casing a vehicle accident. It is important to understand that the airbags deployed before the accident occurred. The airbags did not deflate. I tried to pull the car over but couldn't see around the airbags and hit the car in front of me. The sound of the airbags exploding sounded like a shotgun going off. Since the airbags never deflated, the police would not let me move the car. I had it towed to a garage that my insurance company suggested. They hooked up a device to the computer of the car to see why the airbags deployed. A code came up they said they had never seen, but would not tell me what the code was. It was in the shop for 10 days until the whole inside of the roof was replaced. I picked the Trailblazer up and now I have a passenger side exhaust manifold leak and a tick on the same side. The repair shop says that the airbags should not have caused it and won't repair it. I have read on several websites that report the same problems on other Trailblazers over the years it was made. I think it should be investigated further.

9 Air Bag problem

Failure Date: 05/01/2010

The front passenger airbag does not always engage with an adult of 120 pounds sitting in it. The problem is intermittent, and changes while driving. I was told by chevy and the dealership that I must sit properly in the seat. I always wear my seatbelt. I am 5'7' and weigh 120 lbs. If I cross my legs or put my feet close to the seat (rather than out in front of me) the airbag may or may not disengage. Often, the airbag does not engage even though I am sitting "properly. " I was also told that they cannot correct this problem because they do not see a code. I should also sit closer to the front of the seat. This problem happened at about 32,000 miles and was fixed. Now I have about 62,000 miles on it and they cannot fix it. There is no recall or service bulletin, so apparently there is no problem. I feel this is a very dangerous situation and would like it looked into and resolved. Thank you very much.
