4 months after bring my truck back to the dealership for a body valve issue on the 10 speed transmission. The truck went into limp mode while I was driving.
• the airbag system failed to deploy during a collision that resulted in the total loss of the vehicle. Additionally, the vehicle was operating with a 17” spare tire (undersized compared to the standard 20” wheels), which may have contributed to the accident. The vehicle has been totaled and is currently in the possession of the insurance company, but may be available for inspection upon request. • despite the severity of the collision, none of the airbags deployed, which could have resulted in serious injury if the circumstances were different. The use of an undersized 17” spare tire may have affected the vehicle’s stability, braking, or performance, contributing to the crash. • no. The vehicle was declared a total loss and has not been evaluated for defect reproduction by a dealer or service center. However, I am aware of related recalls and lawsuits regarding both improper spare tire sizing and airbag non-deployment in 2020–2021 GMC sierra models. • the vehicle has been inspected by the insurance company during the total loss evaluation. A police report was also completed at the scene of the accident. To my knowledge, the manufacturer (gm) has not inspected the vehicle at this time. • no. There were no warning lights, messages, or symptoms prior to the crash. The vehicle gave no indication of any issue with the airbags or tire compatibility leading up to the accident. I was involved in an accident in my 2021 GMC sierra. At the time, the vehicle was operating with a 17” spare tire installed, which I later discovered may be significantly undersized compared to the standard 20” wheels. During the crash, the impact was severe enough to total the vehicle, but none of the airbags deployed. Fortunately, there were no injuries, but I believe the non-deployment of the airbags represents a critical product safety defect. I’ve since learned that gm has recalled similar vehicles for incorrect spare tires, and that lawsuits have been filed regarding calibration issues.
I was driving approximately 25-30 mph coming over an overpass moving into the right hand lane when my truck right front end failed. The steering and brakes locked up for approximately 50’ until I hit the curb for the sidewalk and stopped. I safely exited the vehicle checked the left side of my truck for damage and didn’t find anything. I walked around the back of my truck and came to the passenger side where I found my right front wheel and tire completely broken away from both upper and lower control arms, the ball joint broke and failed as well as the brake line. If I was driving on the highway at 65-75 this catastrophic failure could have resulted in a fatal collision. The night before my [xxx] daughter and I returned from her outdoor ed trip in sausalito and we drove an hour home to napa on [xxx] and [xxx] . I thank god this didn’t happen with her in the car on the highway. I had my truck towed to jimmy vasser chevy in napa so I can see if the extended warranty will cover the repairs since it was an obvious catastrophic failure of the whole right front end. It’s still sitting there. The extended warranty inspector came Friday to take pictures of the damage information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

5 days after purchasing and while driving down the interstate at 80 mph, there was a loud clunk at the same time the back wheels locked up for a split second, long enough to burn the tires and throw everyone in the vehicle forward then the vehicle continued on. It happened three more times, we trailered it and brought it to the dealer. They said nothing is wrong with it. However, I was able to locate the previous owners who stated they'd been bringing it to several dealerships to have it taken care of for the past six months and every dealer said that nothing is wrong with it. But the same thing happened to them for six months. One mechanic in idaho even replaced the motor trying to fix it and it still continued. The dealer I purchased from never mentioned it having a new motor, and I pulled the carfax report and it shows several times it was in the shop including the motor replacement, but the shop visits aren't detailed it just says maintenance. Several mechanics we've spoken with say it's in the transmission, drivetrain. But the dealer refuses to do anything unless it'll replicate when they test drive it. But they don't test drive it on the highway or for a long enough time. Multiple owners now in multiple states the same problem and no one will help. This could be a catastrophic incident if the roads had been a little wet or someone was close enough behind us when it happened it would have been a serious car accident, if not worse. I am not sure you can help but im reaching out to everything that I can find.
