Sierra 1500

  • 5,000 miles
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. This is a 2020 vehicle and seems like it will strand me some place at the very least. Awful, expensive, and perhaps deadly dynamics here. GMC, get your act together. You owe us immediately. Provide the fix immediately or give me money back with no contest.

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. It started 4 days after I purchased the truck and happens daily since.
