general problems of the 2018 GMC Sierra 1500

The contact owns a 2018 GMC Sierra 1500. The contact stated that while driving approximately 45 mph on bumpy terrain, the driver’s and passenger’s side curtain air bags deployed unexpectedly. No warning light was illuminated, and there was no impact to the vehicle to cause the air bags to deploy. The vehicle was taken to a local independent mechanic, where it remained for further investigation. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 80,000.

The transmission would purge forward when shifting gears. The shifting was very rough. This vehicle had recently been in accident.

All side airbags deployed for no reason on my driveway at a speed of less than 15 miles per hour. The front airbags did not deploy. No accident. No damage.

Both passenger and driver airbags located behind front seats/where seatbelt is located blew during a collision, seatbelt locked us in during impact,the cab of the truck filled with white smoke and smelt like an electric fire during impact. Problem will be confirmed by a collision center and insurance this week. There’s a lamp warning on the dash board that says there’s a safety warning.

Check engine came on and says manufacture specific issues/codes. Safety restrain system. P10e4.

My rear driver side door electric harness failed only two years after owning vehicle. This disables everything, including the side airbag putting passengers at risk. Most recently (2024), my radio harness failed causing all functions regarding infotainment system to be obsolete. Multiple electric issues and no recalls to be seen.

The contact owns a 2018 GMC sierra. The contact stated while driving 35mph when another vehicle had collided with the contacts vehicle which resulted in the airbags not deploying. The contact stated no warning lights was illuminated. The contact sustained a head injury and did require medical attention and a police report was taken. The vehicle was towed to a local dealer where it was in the process of being repaired. The manufacturer was not informed of failure. The failure mileage was approximately 25,000.

Takata recall : still waiting on a replacement. No action taken by the local dealer. The airbag is still intact, but the vehicle is stored outside in the southeast texas heat and I am concerned about its fragility because of this. Last contact with the dealer was in 2017.
