Out of nowhere multiple warning lights illuminated. ESC, brake system failure, trailer brake failure, do not go over 62 mph. Brakes were near non functioning.

- St. Paul, MN, USA

Started my vehicle and the following messages came up immediately: Brake system failure 62 mph top speed, service ESC, and service trailer brake system. Other lights were illuminated on the dash, such as check engine, ESC, ABS and parking brake. Without turning off the vehicle, I thought it was important to get the vehicle to the dealer immediately as for them to see the vehicle in it's current state. While driving to the dealer the brakes where not fully functional. I would press the brake fully down and it would coast to a stop. Depending on the speed would determine how far it would coast before it would stop. It was a very scary situation. Brake pedal had pressure but the brakes would not start to active until fully pressed. Even then the stop was very slow and would coast. Example, driving out of my office drive to the man road at 5-10mph it coasted a good 30-60 ft. Once the pedal was fully engaged. Vehicle has 667 miles.

Purchased new vehicle with less than 4,000 miles was running fine when parked. When it was cranked to go home listed ESC failure, service steering column lock, trailering system failure, lane departure disabled, speed limited to 60 mph. I was able to get home, but the brakes were so hard that it was extremely difficult to stop. Local dealer it was purchased through "fixed it" less than 1,500 miles later I'm having the same issue! obd has the codes C0021, C0021, P25A2, P25A2, P0606. I do not feel safe driving this truck! if that issue were to happen approaching an intersection I would have no way of stopping in time. Ridiculous.

5 times since I purchased this truck one month ago; shortly after turning on, shifting into gear and starting to move the following displays on the dash 'service ESC, service parking break, flashing orange check engine light', there may have been other lights too but those ones have been there every time. Usually it resets after stopping and turning the car off and on. The ride however is very jerky until I am able to do so and this is not a safe operation condition if there is not a quick and easy place to stop to reset. I have tried to have onstar pull the codes rice but they were not been able to do so in time and they tell me there is no problem when they connect to the onboard diagnostics. It appears they can't see history, only active codes. There was a brake recall on this truck that was supposedly reprogrammed before I took delivery but I suspect that the 'software fix' may not have been successful. In hindsight, my salesman also seemed like he may have been aware of this issue but didn't tell me about it. I say this because the day after I picked it up I noticed that front brake pad life indicated only 68% remaining which seemed low for a 'new' truck that had 2500 miles (had been dealer courtesy vehicle). His response when he tried to clarify was something along the lines of 'and you want me to have them look at the warning about the brakes?', in retrospect that response indicates to me that he may have had an awareness of this problem that I had not yet experienced and was not what I was asking about at the time. He never seemed to understand what I was getting at about the brake pad life when I reexplained so I eventually decide just to forget about it and resigned to the fact that I may have to put new brake pads on this truck before the lease is up in 39 months.

On the dashboard got ABS, brake, engine, tc lights and brakes stopped working, very very poor quality, higher speed 62mph. When I checked with obd reader, got 3 codes and 2 of those codes are tied together with brakes system. When this happened I was driving to work

Vehicle brakes were mushy and the check engine symbol displayed on the dash as was the symbol for steering ( wavy lines under a car picture), also these three codes were scrolling on the dash: Brake system failure 62 mph top speed, service trailer brake system, service ESC. These issues repeated on three separate occasions. Each time I took it to a Chevrolet authorized dealership repair shop where I was told the issue was resolved. Two different shops were used for three " repairs". the issues came up after I started the vehicle by putting my foot on the brake and pressing the start button. The codes began scrolling each time, and the brakes were not firm/ not normal.

Reduced ability to brake my truck almost caused accident.. warning light popped up ABS, brake, traction control with warnings going across dash like brake system failure 62 mph top speed, service trailer brakes. Codes C0021 P0606, & P25A2. Had update for this problem a couple weeks ago and it was suppose to fix this the dealership said over the phone when called today. Never had this problem before.I am pretty sure that update just updates the messaging letting the driver know he or she is about to die. Taking it into dealer later today. Zf TRW integrated brake control (ibc) had early manufacturing issue leaving metal shaving in the units. These shaving would score the walls and damage units, no ones investigating this issue because it would cost GM too much to replace all ibcs in every truck during early stages of the T1 launch. TRW knows of this issue and has piles of these sitting on engineers desks. There needs to be a recall on all early production T1 truck to replace these ibcs. GM has only been replacing these on a case by case bases when someone reports this problem and their VIN number falls within TRW suspected problem dates. By this time its too late and can cause an accidents.

2019 Chevrolet Silverado 1500. Consumer writes in regards to defective brakes. The consumer stated the braked became inefficient at parking lot speeds causing 2 crashes.

- Fresno, CA, USA

On the evening oif 1/11/20, I went to the parking lot and started my truck and multiple warnings came up on the info center for the brakes - brake system failure max speed 62mph; service trailer brake system; service ESC. Check engine light was also illuminated. I turned the truck off, restarted it and received the same message. I was able to slowly drive the truck the three miles to my house with very limited braking capability. When my husband went out to check the truck 15 minutes later, the brakes had returned but the check engine light was still illuminated. I took the vehicle to a local dealer first thing Monday morning and was advised today that they diagnosed a premature failure of the master cylinder. This after the software update in the previous recall had been completed approximately two weeks prior. The service adviser noted this has been a common issue after the software update and has been happening across the country. I believe this needs to be a nationwide recall if the current software update is causing the master cylinder to fail at this rate.

- Edmond, OK, USA

Started the truck up and the check engine light, ABS, brake, traction control lights were all on with a message in the center brake system failure. Limped vehicle to the dealership to have worked on. The braking system is working at about 10%. I am not the only person that this has happened to GM need to recall these trucks and get them fixed before someone dies

- Newton, IA, USA

ABS, ESC, trailer braking system continues to fail. I have had it in the shop three times for this defect. The truck has had 5 recalls, one for the seatbelt, four for the brakes. I drive a lot of miles in rough conditions and do not feel safe in this vehicle. My warranty is up in about 7000 and I don't want to be stuck with this unsafe vehicle.

- Bakersfield, CA, USA

I was backing up at a rate of 15 mph when a message flashed on my dashboard saying something along the lines of unsafe to drive over 62 mph, brake failure, electronic control system malfunction. I hit my brakes and nothing. I kept driving backwards. I couldn't stop until the truck came to a stop on it's own. I turned off the truck and turned it back on with a message saying 'see dealer braking system malfunction.' I was at a storage unit, leaving my unit.

On 1/10/20, I was driving home on a major freeway. Just before 5:00 pm I hit traffic and slowed down to roughly 5-10 mph. At that moment my dashboard lit up and a notification stating, "brake system failure" and "service ESC" popped up on my dash. At that point I was unable to stop when applying my brakes. Luckily I had a large enough space between my truck and the car in front of me as well as the two lanes beside me having an opening and I was able to get over and coast to a complete stop on the shoulder. Extremely dangerous electronic malfunction. Had I lost my brakes 10 second sooner I would have been unable to stop and caused a potentially fatal car accident.

- Houston, TX, USA

Started to drive my vehicle and the braking system was nearly gone. Brake pedal was all the way to the floor and the truck had to slow to a stop. Thankfully I was in a parking lot and not on the road because it would have put my well-being at risk align with others. GM should be forced to recall all of the vehicles with this problem!!! how can anyone be allowed to sell a vehicle that will not properly stop when the brakes are applied?

- Muskego, WI, USA

Twice when pulling a small empty trailer recently, I came to a stop sign and had almost no braking power. The brake pedal was hard as concrete with almost no travel and I had to stand on it to stop the truck which rolled into the intersection both times. Both attempted stops were from a low speed and I didn't have any issues before or after and no warning lights. Good thing I live in a small town with very little traffic or I could have been T-boned.

- Marietta, OK, USA

I was driving going around a corner when I experienced total system brake failure as deer ran across the road and I had to swerve into a ditch to avoid them. I had service ESC, trailer brake system failure and a total brake system failure show on my dash along with check engine lights and other lights I was unaware what their purpose was.

- Branson, MO, USA

I own a 2019 Chevrolet Silverado 1500 ltz. I purchased it new 35 days ago. I recently encountered a very dangerous situation. While driving 25 mph, the vehicle lost it's braking ability. The brake pedal was fully depressed but the truck would not stop. The vehicle coasted until it came to a complete stop. The display indicated service traiier brake system, service ESC, brake system failure, and cel. I powered the vehicle off and restarted it. The cel remained on. The other lights went away. The brakes appeared to work better but when I applied them I experienced a jerking motion. I called my local Chevrolet dealership, prince Chevrolet, ledo rd. Albany, ga. I scheduled an appointment that yielded no resolution as my check engine light remained on when I left the appointment and is still on now. I was told that the problem "might" be a result of starting my vehicle using the "my Chevrolet" mobile app. I was informed that nothing was done to repair the issue as they didn't know exactly how to fix the problem at this time. I was informed that the tech did find a service bulletin and based upon the contents thereof, I was advised not to use the app anymore. Further, I was told that I would receive a call when a solution was determined. The failure mileage was 2400.
