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. I lost power steering and was almost involved in a serious rear-end collision. 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. 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. This is the 5th time this has happened to my truck.

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.

I had no issues with my truck until I went and had the most recent recall done for the brakes. I since have had brake issues twice. Once, hours after having the recall done I got in my truck and started it and all the dashboard lights were illuminated and I had to push the brake pedal to the floor after accelerating. 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.

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.
