4 messages appeared on digital dash while driving. Service ESC, brake system failure 62 mph top speed, service trailer brake system, steering assist reduced. I had to press brake pedal to the floor with extremely excessive force to get truck to stop. Note that none of the 4 messages state the vehicle will be extremely difficult to stop or shouldn't be driven, but rather the vehicle wouldn't exceed 62 mph. It should have reduced the speed to much less, maybe 10 to 15 mph. This failure could have easily resulted in vehicle accident, or even a fatality accident. I doubt I will ever carry my family in the truck again due to this and I certainly will not allow my children to drive the truck.

My pickup started, I pulled out on road and sped up to 35 mph, when I stepped on brakes to slow down they were unresponsive, so I began pumping. They felt very hard to pump and were not slowing the truck down. Lights came on saying service brakes etc. As I coasted to try to slow down off side of road. I had to keep pumping the brakes down to floorboard and I'm not sure they were even working as I coasted safely off side of road to a stop, I turned engine off immediately calling my dealership service department. I wouldn't drive it any further as I felt I had no brakes whatsoever. Dealership had it towed to their shop. The next afternoon I spoke with them. They stated it was a known issue and that a recall had been issued (see recall number below) but I never received it. I did receive a seat belt recall so I know they have my correct address. I was told it was some problem with a module and I can come puck truck up. It was scary when it happened. I purchased this pickup new on August 21, 2019. Recall number: Recall-N192268090 (per dealership service department)

After my recall was fixed my truck locked into 4 wheel drive and I lost control of all my safety features. My lights would not work. They fixed what they said was a glitch in the recall and 3 weeks later my engine light came on again and my brake system started to show lights. They recalibrated the brake system recall again.

After having a recall issue fixed on the ABS braking system of my truck, I remoted started it from GM's onstar app, which caused the dashboard to light up like a christmas tree and give a number of errors, including a solid engine light. GM onstar diagnosis identified that there is now another issue in the ABS braking system. There has been no mechanical failure at this point, but I am concerned their maybe as others with this same issue have seen mechanical failure.

Upon starting the vehicle and taking off after remotely starting it, multiple warnings popped up on the trucks dic. They were, system brake failure, trailer brake failure, ESC failure, do not exceed 65mph warning. After seeing those I applied the brake to stop and the brake pedal went to floor leaving the truck without any type of braking power what so ever. After coasting to a stop I shut the truck off restarted it and the check engine icon was on. The brakes did work after the truck was shut off and restarted.

The other instance was a week later after remote starting my truck from the phone application had the same scenario play out.

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.
