The contact was attempting to retain a physical copy of the Owner’s Manual and thought that it was a safety issue since there was a safety recall.

“transmission locked up 8 times from 1,050 miles to current 3,885 miles. It has happens each time around 40 mph. Each time it’s like hitting the brakes. The 8th time it locked really hard like slamming on the brakes. I’m worried with winter months what will happen on snow/ice covered roads. Called dealership and was told GM refuses to do anything until it completely fails. It seems they know what the problem is but refuse to fix till the truck stops moving during complete failure. No warning lamps and dealer ship says they can’t replicate it.”Owner report · Power Train · Nov 2025

“While towing a less than 2000 lb trailer I had total loss of power steering when speeds dropped below about 5 mph. I got off interstate and was turning right at the end of exit ramp and I could barely turn the vehicle. At the next stop sign it did the same thing. I stopped turned off the vehicle and restarted it and it continued this for the next few miles. Then just as suddenly as it started it stopped doing this and worked fine the rest of my trip.”Owner report · Steering · Aug 2025
