I started my car and I had 4 messages appear on the dash stating(service ESC, service trailer brake, brake system failure-62 mph top speed and steering assist reduced drive with care). I attempted to drive the vehicle in my neighborhood and noticed that I had lost power steering and when I went to brake there was a delayed response. It took the vehicle approximately 4 to 5 feet to come to a stop after braking. Also the ABS, check engine, brake and traction control lights were illuminated. I immediately tried to drive back home and when I drove in to my driveway, I smashed on the brakes and I almost drove through my garage because the vehicle would not stop immediately. I tried to press my onstar button for road assistance and lost all electrical power. I contacted onstar with my phone and had the vehicle towed to the dealership where I purchased the vehicle. Currently the vehicle is there being diagnosed for the problem.

June 27th I was leaving a gas station in novato ca with my daughter and father in the truck. I slowly started moving through the station and noticed my brakes were almost completely gone. Fortunately I was close to home so I dropped down to first gear and slowly motored home to wait for the tow truck. I had the truck towed to the novato Chevy dealership and they could find nothing wrong with the truck. I then began the process of requesting GM to buy this truck back and its definitely not going to be a short process. Im still currently driving this thing with no diagnosis of any brake issue. My wife won't even get into the truck. I absolutely love this truck and wish there was a definitive answer to what happened. GM corporate said if it happens again to please bring it into the dealership for eval. If it happens again?!!! im not complaining about the air cooled seats not working properly! I drive a fire engine for a living and my job is to keep others safe. Now I'm having to drive this thing while waiting for GM to step up and buy this back before the brakes go out again. I suppose someone will have to die before GM acknowledges there's an issue here.
TL contact owns a 2019 GMC Sierra 1500. When the contact started the vehicle, the 'brake system failure 62 mph top speed', trailer brake, service ESC, and steering assist indicators illuminated on the instrument panel. Also, while the contact was testing the brakes in a parking lot, the brake pedal became soft and felt as if it could extend to the floorboard. The contact also stated that he had to apply excessive force to the brake pedal to stop the vehicle. The vehicle was not diagnosed or repaired. The dealer and manufacturer were not notified of the failures. The approximate failure mileage was 750.
Picked up my 2019 Sierra AT4. I drove it off the lot, got about 3 miles. Stopped to get myself a cup of coffee. Got back into the truck, started it and the check engine light came on, the brake system failure, the ABS light, traction control etc. Called the dealer and was told to bring it back. (mind you, I've only actually owned the 63K truck for an hour) I bring the truck back, they take it in for about 20 mins and then the mechanic takes the car for a test drive. He's gonna about 15 minutes or so, comes back and says the truck is good. They fixed a recall recently but never "reset the computer" he says "you're good to go" I drive the 30 minutes home, pull up to the house, turn the truck off. Go inside to get my little ones because they want to go for a ride in daddy's new truck.. we go outside, I start the truck, and it's the same thing these are the codes that came up. It has been back to the dealer 3 times and they havem't found any issue. This is dangerous and something needs to be done.

On 5/28/19 I filled my 2019 GMC Sierra denali at the local gas station. As usual I turned the vehicle off. After fueling, I started the vehicle and began pulling out of gas station. Upon exiting I lost all braking power and the pedal went to the floor. I was going approx. 5 mph. I pulled over and had to step on the brake pedal until it was on the floor with extreme force. The check engine light also appeared on the dashboard. At approx. 4:41pm I recieved an onstar email with an antilock brake problem. Email suggested I take the vehicle for service within 7 days. I had GMC roadside tow the truck from my home to the nearest dealer(staten island Buick GMC) I leased the vehicle from coleman Buick GMC and when I contacted them I was told they couldn't help and the dealer the truck was towed to is still GM. I also contacted GM customer service. Received a case # and waiting to be contacted. As per coleman the vehicle has recalls for a trailer brake module and park assist. As per si Buick GMC they could not find any computer codes. The hydraulic test showed no issues. They claim to have upgraded the computer and the truck was safe to drive as of 5/30. They want to test drive again on 5/31 and I assume I'll be asked to pick up my truck. I find this to be unacceptable and a major safety issue. Thankfully I was going 5mph when I lost full braking. I was told if the issue happens again to bring the truck back in for diagnostics and repair as needed. This safety issue can potentially cause physical injury and or prove to be fatal. Depending on technology to determine braking capacity is absurd. 2019 GMC Sierra also have electrical problems duly noted by customers. Forums also mark the same braking problems have occurred with other owners in different states. A recall should be issued for the safety of drivers, passengers and pedestrians! lives are at risk and a recall is needed!
On April 2, 2019 I parked brefily for about 30 minutes. Upon re-entering my 2019 GMC Sierra truck with approximately 4500 miles and starting the engine I immediately received multiple warning messages on my dash panel. They were "service ESC" "service trailer brake", "brake system failure" "steering assist reduced" and to drive no faster than 62 mph. Previously prior to parking I had never had any problems whatsoever. I was in a location where I needed to go so I attempted to drive but found quickly that the brake pedel went all the way to the floor with very limited or basically no braking. The steering became very difficult with no apparent power assist. I drove it approximately two miles and got to a location where I could park. I turned the engine off and back on and the problem did not go away. I turned it off again and waited a couple of minutes and then heard an automated couple of clunk sounds from the front.. I started it up and everything was okay except the check engine light was on and stayed on the rest of evening. The next morning the check engine light was still on however about twenty minutes later I noticed it was off and everything has been fine since. I had planned to take it to the GMC dealer however with no problem showing now and from past experience with the dealerships I decided there was no need to schedule an appointment until the symptoms come back. I found on the internet later that there are numerous instances where this has happened to many other 2019 GMC Sierra owners. I feel that this is a extremely serious problem that needs immediate attention especially with the near total braking system failure!
I am a heavy highway construction inspector for wvdoh and while working on I 81 sb in martinsburg, wv this morning around 2:00 am while performing my duties I attempted to pull out of my lane closure into traffic when my truck literally got stuck halfway out into live traffic. It was as if I was stomping on the brakes instead of giving it gas. Fortunately I reacted swiftly and put the truck in reverse to back into my lane closure preventing a collision with a tractor trailer traveling at speeds in excess of 55 mph. I was literally shaking when I realized how close of a call it actually was and that not only could I or the truck driver have been killed, but so could the workers on my job have been injured and/or killed. I had to have my truck towed back to my field office. For some reason the truck started driving properly again. There is definitely something wrong and it is extremely fortunate that no injuries occurred on my project. I did notice a post on this website explaining the very thing that happened to me this morning. This issue must be addressed immediately before people are killed.

While driving my truck approximately 45 mph on a street, I heard the vehicle notification alarm sound, I looked down at the dash and had several warning lights illuminated:I had four messages: Service ESC service trailer brake brake system failure - 62 mph top speed steering assist reduced drive with care lights on dash that were illuminated ABS check engine brake traction control before I could read each warning light, a red stop light was approaching. I was at that time I pressed on the brakes and realized that my brakes were extremely spongey. I figured I only had about 10% braking power. With my two year old in the back seat, I pushed as hard as I could to stop my truck. Luckily, by the grace of god, I was able to stop my truck without rear ending the car in front of me. My truck was then towed to the dealership. I bought the truck 5 days prior. My truck has approximately 161 miles on it. The dealer told me the next day I needed a new master cylinder and hydro boost. Probably the absolute worse component to fail on the driver while the vehicle is in motion.
Have about 6000 miles on my 2019 GMC seirra denali 5.3. I've been experiencing a very troubling issue been to the dealership once already and had a hard time convincing them that something was wrong with the truck.every time I drive for long periods of time or idle for 10+ mins when I shift from park to drive I cannot go faster than 5 mph without the rear brakes locking up. I do not know if this is some kind of limp mode or what.
