When I was at a stop light on a city street and I pressed the gas pedal, the brakes locked itself and I could only go 5mph. This is the fourth time it has happened.

- Naples, FL, USA

Driving my 2019 Sierra on a slightly snow covered road applied brakes and truck pulled to the right and antilock brakes never worked causing me to hit guard rail. Called insurance talked with dealer about what happened they said to contact GM customer service. Had my wrecked truck fixed and when GM got back to me they said there was nothing else they could do because I contacted my insurance instead of dealership"??" now I have received another recall notice telling me my brakes are not responding properly. Guess I need a lawyer I don't know.

At around 1500 miles my truck had a rotational noise which led into clicking the grinding and squealing, they changed out the front axle and all new brakes and rotors along with a braking software update. They assured me I should not have any more issues. Now at 4,300 miles I'm starting to have rotational noise again after driving about 1 hour, of course they cant duplicate noise. The truck has had 5 recalls and also a 4WD pump defective all with 4,300 miles. I am fearful that the brakes will fail

- Stamford, CT, USA

When I started my vehicle this morning, I got a warning of brake failure that came up on my dic; this has been happening a lot. I just took the truck in last week for the 4th time and they did another update due to the last recall that was put out by GM. Nothing seems to be working with this brake issue. The brake pedal at times seems to have difficulty when I'm starting the truck. I did not use my remote start on any of the issues I'm having.the truck was parked in my drive way yet it's also happening at various places around town as well.

Service ESC warning on dash service trailer brake on dash brake system failure - 62 mph top speed warning on dash steering assist reduced drive with care on dash restarted truck and check engine light came

- Charlotte, NC, USA

Multiple warnings popped up on the screen telling me "brake system failure" "ECU failure" "trailer brake failure" and "max speed 62 mph." After that the brakes become almost non-functional. I had to stand on the pedal with both feet and was unable to slow down enough (45 mph traffic) to had to go into the E-lane to avoid an accident. Truck also gave dtc P25A2. I can't stress enough that it wasn't just degraded braking, it was almost nothing at all. It took nearly 1/8th of a mile to get it stopped on a mild downhill grade.

- Maineville, OH, USA

Started with ignition button put in reverse backed up went to stop and realised brakes are not working as usual had to stand on pedal to stop. Checked mirrors to make sure I didn't hit anything I didn't.thought maybe I hit side of brake pedal so I applied the brake again and figured I lost brake boost. I checked for warning lights there were none.brakes did not work properly until I restarted truck.then I felt the pedal reacted properly. Called dealer they did a recall but recall didn't specifically match my brake loss. I can only hope it's fixed

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.

I have had the 2019 Sierra 1500 AT4 with 6.2 liter engine in the shop (8) times since purchasing it in late Aug 2019 for multiple issues, including the issues relating to the brake software recall. This resulted in me rolling through a stop sign without any brakes. Luckily there was no oncoming traffic. As an engineer, I have no confidence that the issue has been fixed long term by GM. My family will no longer ride in the truck with me. As a result, I have retained an attorney for the purpose of filing suit against GM for selling me an unsafe lemon. Even further concerning is the fact that on (2) occasions the parking brake has engaged while driving down the highway at 55 mph. One time while in 4WD in snow, and the other time while in 2wd on dry pavement. The first time there was a diagnostic code associated with the parking brake engaging randomly. The second time, there was no diagnostic code present. The first issue with braking began 11/14/2019, and the most recent issue occurred on 2/2/2020 even after all recall "fixes" have been applied.
