Purchased new, Dec 24, 2019. Current odometer 645miles. The vehicle was parked for about 15 minutes, when I returned to my truck and turned it on, multiple warning tones began to sound and the dashboard was illuminated with multiple warning lights (ABS, traction control, check engine, parking brake) and messages reading: "brake system failure 62mph top speed, " 'service trailer brake system, ' 'steering assist is reduced drive with care, ' 'service ESC.' I turned the vehicle off and on multiple times over the course of 20 minutes, exiting the vehicle, locking the doors, unlocking the doors, and starting the process from the beginning. I decided I wouldn't be driving over 62mph as I was only 2 miles from my home, so I decided to back out and drive home with full intentions of calling the dealership in the morning. When I tried to back out I realized that I had almost zero braking power, having to almost stand up on the brake pedal to stop the vehicle without giving it any gas, and turning was difficult (similar to manual steering in a vintage vehicle). I knew driving home would not be safe. I turns the vehicle off and on once more and all the warning messages and lights were no longer there. The check engine light remained on and is still on. I was able to drive home as though nothing happened, but am fearful this will happen while driving down the road, especially while my children are in the car. I have read multiple forums, this is not an isolated incident, with many others experiencing the same exact issue, sometimes while actually driving, in 2019 GMC Sierra and Chevy Silverado's. this is absolutely unacceptable and will result in injuries and deaths if GM does not resolve the issue.

I received notice that there are two recalls out for my truck: A brake system recall and a forward camera/collision recall. Had both recalls performed and immediately the forward camera collision alert, lane keep and intellibeam systems didn't work. Delaer informed me there is a problem with the update and I need a new camera. That is on order and pending. More importantly, about 2 days after the updates the truck showed alerts about the brakes, traction control and stabilitrack systems. Upon driving the truck the power/vacuum assist system failed and the brake pedal nearly went to the floor before engaging brakes; I could barely stop. Returned the truck to the dealer and was told its a common issue with the brake recall update (the truck had no such symptoms before the update). If you check out various GM vehicle owner forums you will see scores of Silverado and Sierra owners with the same two issues post-update: No collision camera and sudden loss of brakes. There is a problem - a very dangerous problem - with these updates.

Dear NHTSA, I recently leased a 2019 GMC Sierra pickup truck. This truck is currently in the shop for the 6th time, and neither GM or the local dealership can seem to fix anything on this truck. Most recently, as yesterday I had my car in for the braking system. The dealership called me and said my truck was fixed. As I turned my truck on, the brake system light came on. I was told by the dealership to just drive it and it will go away. I do not feel this is a good/safe practice and GM is not helping me to get out of this unsafe truck.

Brand new truck, AT4, 15K miles, 5 months old. Was very cold today outside, was in a store and started vehicle remotely. Came outside to a running vehicle, sat in drivers seat and pressed start button. Noticed multiple warning sounds/lights, dash read "brake system failure 62mph top speed", service trailer brake system", steering assist is reduced drive with care" service ESC". the ABS, check engine, brake and traction control lights were also illuminated. I immediately called my local GMC dealer (who is 5 miles away) and read them all the messages and asked if the vehicle was safe to drive to their location. After a brief hold, the service tech stated the vehicle was safe to drive over. I attempted to drive the vehicle out onto RT6. While still in the parking lot, traveling approx 10-15mph I was barely able to stop the vehicle. It took my full power on the peddle to stop, and approximate 20-30 feet of distance before it stopped fully. I immediately called the service tech back and informed her that the vehicle was not safe to drive with 5% or so break capacity. She provided the GM number for roadside assistance. The truck was towed to their shop a short time ago and I am awaiting their feedback. On a side note, I waited in the truck as I did not want to shut it down, I wanted the service tech to see exactly what was on the screen. After about 30 mins, with me in the drivers seat with the keys, the truck shut itself off. When it restarted the messages were gone, but the check engine light remained. Luckily I took photos and video recorded this issue prior to. The loss of brakes for any issue should be treated with the uttermost care for safety of the general public. This seemly known issue will (if not already) result in injury or death if not corrected quickly.

- Wyoming, MI, USA

Brand new 2019 GMC Sierra AT4, just under 14K miles. Upon starting the truck, the following warnings came on. "brake system failure 62mph top speed", service trailer brake system", steering assist is reduced drive with care" service ESC" check engine" I turned the trick off, opened and closed my door, then restarted. Upon restart, everything was gone, no warnings. Approximately 1.5 miles later I was at highway speeds (70mph) when all the messages returned. I attempted to brake but there was no response, pedal went nearly to the floor. I only survived the incident by shifting into manual, downshifting to engine brake, and standing on the what I'm guessing was 5 or 10 percent brake pedal. Luckily there was an empty lane for me to do this in.
