“While driving highway speed (75mph) the steering went out as I was trying to go thru a curve., I had to use both hands and force the wheel to turn to exit highway. Luckily it was only a slight turn I was trying to navigate! It threw service code'c0475, they say it's the steering gear! $2700 fix I believe it's electronic error.”
NHTSA complaint #11337730, filed 2020-07, 47,000 miles“I nearly died when my brakes failed on my 2018 Gmc denali this morning. I was only going 60 MPH when another driver cut in front of me, and hit their brakes but when I tried to stop, I could not! I then began swerving from lane to lane because it was raining. Thank god I didn't die and that the person on the right slowed down and moved out the way. The truck seemed to be pulling me to the right. Why I have no idea. But why is GM putting people lives at risk like this? Why are we having to suffer or put our families in jeopardy. This makes no sense. …”
