2020 GMC Sierra 1500 Steering Problems

“On december 14, 2020 my sierra with 2339 miles displayed, at startup, the power steering was out, to drive with care. Also displayed service ESC and traction control failures. I drove with much difficulty, without power steering, ten miles to the nearest Gmc dealership, lafontaine in highland, mi. I picked up the vehicle on december 29, 2020 with an additional 60 miles. The service personnel said they were unable to duplicate the problem, therefore no repairs were made. …”

“My truck tuesday march 16th had me update software as soon as I got to work, after it was done I got out of my truck and it would not lock with push button or fob. When I got into my truck to go home 10hrs later it made a bunch of clicking noises and after a minute it showed update complete on screen then started. The very next day I drove back to work which is 22 miles. When I took my truck to lunch three blocks away I had ESC service light and service parking brake accompanied by check engine light. …”

“The steering will completely lock up, this is the 2nd occurrence. It was at the dealer 1143 miles ago and codes were cleared, problem reoccurred. I was able to start the vehicle, put in drive/reverse neutral etc without issues, however the steering was completely locked up and would not allow steering/control of the vehicle. The vehicle was parked in driveway, cold outside both times. I have video evidence. The first occurrence 12/26/2020 at 9591 miles, 2nd occurrence 2/16/2021 at 10733 miles (1142 miles later)”

“Everything was fine for about 6 months after having purchased vehicle as new. Then I got warning lights asking me to both service the parking break and service ESC with a warning that driving would be compromised just over 60mph. I notified dealer who says they fixed the glitch but it happened again. The last time, most recently, I tried to start the truck the next day and all the warning lights came on. This was followed by a complete shut down. No engine, no lights - not even lock/unlock with key fob. It had to be towed. …”

“I was going about 15 miles per hour when suddenly all these error codes started popping up, first ESC malfunction then trailer brake malfunction,stabilitrak, steering assist reduced, brake system fail, lighs just pop up I do feel like the truck looses some power feels more sluggish, I took it to dealership, they recalibrated the break system and stuff, it fixed the issue temporarily, but the lights keep coming back, sometimes I turn the truck on in the morning and lights are gone, then later on I get all the error codes again while driving it. …”
