NHTSA complaint 11736042While driving on the highway in light traffic at approximately 70 mph and changing lanes, the side airbags in my vehicle suddenly deployed without warning. There was no collision, no contact with another vehicle, no road debris, and no apparent external cause for deployment. I did not strike anything before, during, or after the deployment. There were no vehicles within several car lengths of my vehicle at the time. Highway Patrol was dispatched to the scene. Officer TJ Carter with Guilford County responded. Upon inspection of the vehicle at the scene, we found no evidence of impact or contact with another vehicle, object, or debris. The vehicle was covered in yellow pollen at the time, and even light contact would have left visible marks or disturbance in the pollen. After examining the vehicle, no signs of contact were identified. The vehicle does have unrelated prior body damage from over a year ago on one side, but that damage predates this incident and was not caused by this event. The responding officer can confirm there was no collision or new impact associated with the airbag deployment. There was no accident associated with this airbag deployment. The airbags deployed while I was traveling at highway speed, which caused a sudden and dangerous driving event and required me to quickly maneuver to the side of the roadway. This created a serious safety risk to me and to surrounding traffic. Prior to this incident, there were no warning lights, safety alerts, or service notifications indicating an issue with the airbag system or vehicle safety systems. However, a notification did appear in the My Chevrolet app at or around the time of the incident. The vehicle has not yet been fully inspected following the incident. A safety claim has been submitted to General Motors. I also have video footage of the Highway Patrol Officer cutting down the airbags on-site but cannot add that below so I have added a screenshot.
NHTSA complaint 11727596The bolts holding the exhaust to the catalytic converter broke while I was driving my car. The car could have flipped, the exhaust could have busted through the vehicle, or I could have caused an accident and died. This comes on the heels of the EXACT SAME THING happening to my wife's Chevy Trailblazer with nearly the same mileage as mine. I have 97K miles and she 96K. This is a KNOWN ISSUE to them and it is NOT THE FIRST time this has occurred. There are thousands of similar instances that have occurred and one can easily find the anecdotes through an online search.
NHTSA complaint 11724711The Onstar module has went out on my car and while researching the issue I found out that it is a very common problem with Chevrolet/GM vehicles years 2021-2025 and although Chevrolet and GM are wwll aware that there's an issue and that the onstar modules are faulty there's been no recall. Mind you the module doesn't just affect onstar features it also is connected to bluetooth microphone and remote start and now none of them work at all.
