SERVICE BRAKES PROBLEM

Date Of Incident: 2024-02-05
VIN: 1GT49WEY4PF
Components: SERVICE BRAKES
Summary: CRITICAL PART FAILURE - The master cylinder attached to the brake pad is leaking at the seal where the piston is depressed into the cylinder. It's leaking brake fluid onto the driver brake assembly and some sort of cable. While this is repairable under warranty, this should NEVER ever happen on a vehicle. Arguably, the main part on the most critical system on the car - the brakes. Please investigate whether GM should be responsible for replacing this part on any affected vehicle for the life of the vehicle Thank you for all you do to keep us safe! Have a great day

FORWARD COLLISION AVOIDANCE,LANE DEPARTURE PROBLEM

Date Of Incident: 2023-03-27
VIN: 1GT49WEY6PF
Components: FORWARD COLLISION AVOIDANCE,LANE DEPARTURE
Summary: On March 22, 2023, my wife and I purchased a new 2023 GMC Sierra 3500 Denali from Coast Buick GMC. Before purchasing, we asked the salesman if it had adaptive cruise control and lane keep assist, and he said yes and showed us the buttons and explained how they worked. We purchased the truck because it had these features. Four days later, on a trip out of town, we found that the adaptive cruise control and lane keep assist did not work. We looked online and saw similar GM vehicles with the same buttons, showing how to use the systems, but ours didn’t work. During our trip, the salesman texted me and said he needed me to sign a document. I told him that we couldn’t figure out the adaptive cruise control and lane keep assist, and Sal responded in writing via text, “OK be my pleasure to show you the adaptive cruise and lane keep assist.” We came into the dealership the next day, on March 28, 2023, with only 251 miles on the truck, and were told it didn’t have these features. The Dealership and GM have refused to make this right. GM’s design of the buttons in the truck for the warning systems closely, if not exactly, match the buttons for adaptive cruise control and lane keep assist options in other GM vehicles, which is very misleading. My brother-in-law has a 2020 model and he still thinks his has adaptive cruise control and lane keep assist, but they just don’t work very well, even after I told him it doesn’t. Today, while dropping off my truck at the GM Service Department for repair, the Service Department Representative said a lot of customers were told their GMC HD truck had lane keep assist and adaptive cruise control. This is a fraudulent or misleading design, which could result in serious injury or death.

AIR BAGS PROBLEM

Date Of Incident: 2023-01-20
Number Of Injuries: 1
Crash: 1
VIN: 1GT49VEY1PF
Components: AIR BAGS
Summary: I was in an accident and was hit in the right front side of my truck. The other vehicle was believed to be going around 50 mph and I had just rolled thru a stop sign. The other vehicle that hit me had the air bags deploy, but my airbags did not deploy. This is very concerning considering there was enough force to significantly bend the frame on my truck. I was transported to the ER and suffered internal organ bruising due to the accident. If the airbags would have deployed, my body could.have not jolted so much causing these injuries.
