Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I received a recall notice for a brake problem on my truck. The recall gave a location to take my truck for service. When I contacted that dealership they said it was a canadian truck and they couldn't perform the recall repair. So I called the GM hot line they said I had to take it to canada for the repair and that was the only option.”

NHTSA complaint #11349539, filed 2020-08, 23,000 miles

“I was in the bank atm drive through and the guy ahead of me started to go, I barely pushed the gas pedal and he decided to stop. I hit my brakes and the truck was hard to stop, almost like the gas pedal response was still in the go mode before it had the chance to react to my input of taking my foot off the gas to apply the brakes. I can duplicate this behavior all the time.”

“My 2018 Gmc sierra slt's break pedal becomes extremely difficult to press, and I can hear something that sounds like air coming from the pedal. This happens especially at lower speeds.this caused me to crash into a concrete wall and damage my truck. My truck has only 10,000 miles.”

“Driving slowly in bumper to bumper traffic. I was stopped with my foot on the brakes, and the truck started moving forward. I thought engine surge, but it was not. I pumped brakes hard and the truck stopped. This has happened 2 times.”

NHTSA complaint #11183101, filed 2019-02, 2,000 miles

“The first thing that happened was that all of the electrical systems on my truck went out and my truck would not start. It finally started but it would not move finally it would move but very slowly this happened on 11/20/2019 I have documentation through onstar for this incident. My brakes started slipping on 07/01/2020 and still do not work properly. My transmission has never shifted correctly. When I accelerate or when I slow down there is a shudder and a jerking sound. After sitting for a while when my truck is put in reverse it hesitates and then seems to jump into gear.”
