Dash flashed Steering assist reduced while I was driving and then I lost all power steering nearly crashing the vehicle. Upon bringing vehicle to a stop I turned off vehicle exited and looked under hood for anything obvious. Upon restarting the vehicle warning was gone and power steering returned. I was advised by GM that a recall for this problem is available for previous year but not mine. I am afraid to drive vehicle, worried the problem will occur again.

When in park and I shift the transmission into Reverse, the force engaging the gear bangs and shakes the vehicle. The transmission is not regulating the power. The vehicle is available for inspection. I took the vehicle in to the dealer service and they were able to reproduce it. They claim that there is a bulletin from GM motors and this is considered normal. The bang is hard and shakes the vehicle, definitely not normal. It started after 50k miles and the truck has 62k miles now. No one else inspected the vehicle and no warnings are indicated by the vehicle.

While driving home from work around 6 am, my car had multiple warning lights and warning messages come up all of a sudden. Immediately after that I lost my power brakes and steering and was not able to control my car at 40 mph. I was lucky the light I passed was green and there was no other traffic. I was able to bring my truck to a stop after more than a quarter mile by putting all my weight on the brake pedal. The truck was towed to the dealer and has been there ever since.

I parked my car for about an hour after driving for months with absolutely no issues or warnings. When I started my car and went to pull off the steering wheel locked up and I couldn’t turn it. A message appeared on the screen saying: Service power steering drive with care, and an esc message. A light also appeared. I turned the car off and let it sit for an hour. When I started it again everything worked fine. My dealership won't do anything because the warning codes went away, and the vehicle is not included in any current recalls. When looking up this problem it appears there are multiple recalls for the exact same issue on other 2021 Yukon and Tahoe models but not the Sierra. Though I see many forums and threads complaining about the same problem on the Sierra's. Since it is the same vehicle and systems as the Yukon, shouldn't the same recall apply?

Noticed a scraping noise after new, recommended tires installed on my stock truck. Checked the door label to ensure correct tires installed, they were, returned to the tire facility and they recommended I ask a repair facility to investigate. Found that the tires are rubbing the upper control arm when fully turned left or right (both sides affected). Went online to discover that this is a common issue with the 2018 and similar GMC Sierra and Chevy Silverado trucks. This is a safety issue caused by a design deficiency. Two things can happen. One, the tire can fail. Two, the upper control arm could fail, causing the vehicle to be uncontrollable. This could be fixed by restricting the extreme left and right travel in the steering system or redesigning and replacing the upper control arm so it doesn’t interfere with the tire. This is an unacceptable safety issue caused by a design deficiency and needs to be addressed by NTSB now.

Brakes intermittently quit working at slow speeds. Sometimes while pushing on the brake pedal, the brakes don't respond, I have to increase the force placed on brake pedal. There is also a pulsating sensation at the pedal like the ABS is being applied, even though I am traveling at slow speeds, and it takes much longer to stop the vehicle. There are no warning lights that come on and there is nothing on the message center stating there is an issue. Has happened multiple time, usually in a parking lot, or in stop and go traffic. Also has happened when vehicle is in Reverse. Have never had the issue at highway speeds.

The contact owns a 2016 GMC Sierra 1500. The contact stated while driving 60 MPH, the instrument panel went blank with white smoke coming from the vehicle. While approaching a stop light, the brake pedal depressed to the floorboard; the contact used the parking brake to stop the vehicle. Once the vehicle came to a stop, the contact was unable to turn off the vehicle. The contact poured water over the engine as the heat melted a switch that connected from one battery to the other. The contact managed to restart the vehicle and resumed normal driving. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 200,000. The contact stated that the failure mileage was at or around 157,000. The cause of the failure was the second battery's positive cable became shorted out.

Radiator failed. Mileage is under 60k. It is currently being replaced by dealership. Dealer Representative noted that it is a fairly regular occurrence for these models. So much so that the dealership stocks this replacement radiator(hard for me to understand). There was no indicator lights to alert to this malfunction, it was noticed after work one afternoon when coolant was dripping out of the front of the vehicle.

Alarm codes P25A2 & C05B0 -Brake system failure 43mph top speed -Service trailer brake system -Service brake assist -Service ESC -Check engine light -Traction control light My vehicle is not showing any recall, but obviously I’m not the only one with this issue. A quick research on google revealed several people with the same issue. I’m having to pay for this out of pocket for an obvious issue with GMC & Chevy trucks.
