I was traveling north on interstate 95 and approaching my exit ramp. I was initially in the inside lane of travel. I accelerated to merge into the outside lane, between two other vehicles, and then onto the exit ramp. Once on the exit ramp, I let off of the throttle and the engine suddenly shut down. I noticed a message on driver information center instructing me to shift the vehicle into neutral and press "start again". The engine had shut down without any warning whatsoever. I complied with the instructions to no avail. The truck is over half full of fuel. I was within an hour of home after completing an approximately 8 hour, 500 mile, round trip over 2 days of driving. After this event, I connected an OBD2 scanner and the only code found was P25A2 brake system control module. I placed the truck in park and tried repeatedly to start the engine. It would not turn over, crank or start. I had power to all systems and no other codes. I had to have the truck towed from the scene. The truck's performance had previously been flawless during this entire trip and had given me no warning whatsoever of the sudden engine shutdown. This is extremely dangerous and a safety concern.
Vehicle was having trouble accelerating, like the parking brake was on. Then received a message that the brake system failed, lane assist failed, and I couldn’t drive faster than 43 mph. Then a message about the trailer brake appeared
The contact owns a 2019 GMC Sierra 1500. The contact stated while driving approximately 20 MPH, the vehicle came to a screeching stop. There were no warning lights illuminated. The vehicle was towed to the local dealer, where it was diagnosed that the electronic brake control module had short-circuited and there was a miscommunication, which engaged the parking brake and locked up the rear wheels. The vehicle was not repaired. The vehicle was previously taken to the same dealer on two occasions and repaired under the federal safety agency Campaign Number: 19V889000 (SERVICE BRAKES, HYDRAULIC, SERVICE BRAKES, ELECTRONIC STABILITY CONTROL (ESC); however, the failure recurred. The manufacturer was contacted and opened a case, but no additional assistance was provided. The failure mileage was approximately 7,000.
On a normal trip to work the dash light lit up then gave me these warnings. Service ESC, Service Trailer brake, Brake system Failure-62 mph top speed, steering assist reduced. Dashboard lights that were on, ABS Check Engine, Brake, Traction Control. When I tried to slow down the power assist was gone on the brakes, I had a little braking when I pushed the pedal all the way to the floor as hard as i could, when I went to turn the wheel was hard to turn. I have had no issues like this before. After I managed to stop and turn off then on the vehicle everything came back expect for a warning to service the trailer brakes and the check engine light was still on. It all cleared after a few more restarts. I got the truck to the dealer 4 days later and they said it was the battery going bad even though I was not having any problem starting the vehicle, I had them replace the battery. I am unsure if the problem is resolved, time will tell. What I am sure of is if my daughter had been driving the truck, she would not have had the strength to get the brakes to work or turn the wheel, she would have had a accident for sure.
Truck showed check engine light and popup message to Service ESC, vehicle disable traction control. Before being able to have the vehicle scanned for error codes (after sitting parked turned off for a while, all errors cleared. Several days later when turning vehicle on traction control warning light, parking break warning light, and stability control warning light all turned on, service ESC message popped up again, PRNDL position indicator light turned off and vehicle began to have a clicking noise in the steering column when break was pressed. There is a multiple year long thread on this topic on the silveradosierra forum entitled "service-esc-and-service-power-steering" it appears that dealer and GM help are limited and the issue often goes away and recurs.

Complete system failure while driving. Lost control of vehicle, no breaks. Had it brought to dealership. Lifter failure and bent rod, top engine failure which caused everything to malfunction. Vehicle has 88K miles on it. This is a defect. We had taken it in for the ticking problem in the past and they did nothing for us. Everything is documented. We are afraid that bottom half of engine was compromised. Do not feel safe driving this vehicle anymore. I do not want it to blow or lose control of vehicle again. This is a known issue and must be addressed. There was a service bulletin put out for my engine and there is an exact part by part that needs to be replaced, however GM is unwilling to listen to us at this time. Please look into this because this will happen to more and more consumers. This is very scary. What is the cost of a life?

Electrical short on brake booster performance error code c0021 while operating vehicle . Brake pedal became stiff and higher than where I had it . Vehicle making hissing noises and will no longer start due to this error. Safety concern this is not part of a recall list. I nearly crashed. I had to utilize emergency brake.
I put my truck in break. Service mode to replace the brake pads. I began changing the pads And could not get the piston to retract all the way, I hooked uon a c clamp to retract the piston. In the event i moved the rotor to another spot and the brake service mode turned off and the piston extended. My fingers nearly got caught in the caliper. When put in brake service mode, it should not automatically extend when turning the rotor. Someone will get hurt bad at some point in a swrvice garage or at home when wirking on brakes.
Question #1- “Service Trailer Brake System”-“Steering Assist is Reduced Drive with Care”-Brake System Failure 43 MPH Top Speed”-“Service ESC” Question #2- I experienced a Complete loss of braking ability, myself, a friend and, a coworker, as well as the properties around me where placed at risk. Question #3 Not yet I am having towed to the dealer today. Question #4 Not yet the vehicle will be towed to the dealer where I purchased it today. Question #5 Not my knowledge I do not recall any warning lights.
Were driving and vehicle repeatedly suddenly braked in the middle of interstate or highway without any warning. We are so traumatized, and scared of this vehicle. It has happened before. Dealership says there is nothing they can do. This could have caused our life. GMC should be held accountable.

driving home at low speed truck would hardly stop took it to dealer-suburban gmc troy mi. received a letter afterwards that brake control module was not repaired properly and needed to return for repair truck showed about 15000 miles on odometer April 2020 and showed 51% brake life on rear brakes-when I asked if brake were worn I was told no and dashboard now read 91% brake life on rear brakes-in March2023 with 28000 miles on the odometer my brake monitor alert came on and when I returned to the dealer I was told that my rear brakes were down to 15% and needed to be replaced. Everyone tells me front brakes should wear out first and rear brakes should last much longer.
I were driving at low speed and all 4 wheels locked causing the vehicle to suddenly stop without notice. I almost got rear ended. I had to put vehicle in park and turn off and turn back on to get it to move. Again it did the same thing stoping with brakes locking suddenly, almost causing an accident in middle of road. There was no warning at all.
Was driving around 70 MPH brakes started engaging and disengaging truck felt like engine was missing, brake light luminated and stated to stop vehicle ABS light luminated as I got to the emergency lane I had no brakes pedal went to floor and I came to a stop after coasting and pressing pedal. Once stopped trailer towing light luminated ( I was not towing anything). I exited truck and it was apparent this was a issue with the front brakes as they were smoking. Rotors appear to have marks in them when compared to rear. After about 30 minutes I started truck and there was no indication on dash of a problem had brake pedal. The truck has 50800 miles on it. Contacted dealer (Hendricks Chevy) this morning they said it was not covered and no recalls I discussed brake issues I read on line again they repeated no recalls in system for my truck, but would be glad to look at it in 2 weeks.
Alarm codes P25A2 & C05B0 -Brake system failure 43mph top speed -Service trailer brake system -Service brake assist -Service ESC -Check engine light -Traction control light My vehicle is not showing any recall, but obviously I’m not the only one with this issue. A quick research on google revealed several people with the same issue. I’m having to pay for this out of pocket for an obvious issue with GMC & Chevy trucks.
I keep receiving trailer breaking system service notifications and as far as I know a trailer breaking system requires no service.
Abs, traction control and trailer break system failure. Check engine light comes on and goes off after 5 cycles. It also says ESC warning drive with care and it flashes also and steering reduced
The contact owns a 2019 GMC Sierra 1500. The contact stated when he started the vehicle, the parking brake warning light illuminated. The vehicle was taken to the dealer and the computer was updated, but the failure reoccurred. On another occasion, while driving 70 MPH, the parking brake warning light and 4WD warning light illuminated. The vehicle was taken to the dealer again and the contact was informed that the actuator switch needed to be replaced. The vehicle was repaired, but the failure reoccurred. The manufacturer was contacted and stated that the vehicle needed to be diagnosed. The failure mileage was 37,000.
The truck has 50,000 miles, purchased new. I don't tow or go off road. I take it to the dealer every 5,000 miles. While driving 65-70mph on the interstate (4-lanes), my dash lit up with five messages and the "Brake, Traction Control and Engine" lights illuminated. I applied brakes but the pedal went to the floor and the steering veered to the left causing me to move out of my lane. The truck then went to limp mode and I was unable to go above 43mph the remainder of the trip home. After taking it to my dealer the next day, I was told they "found air in the brake fluid system due to secondary seal failure in brake master cylinder, and was quoted a new cylinder (PN 86788482) for $1708.06. RESPONSE TO QUESTIONS: >Component failure: brake master cylinder (eBoost Brake Unit Assembly) / Brake System Failure >It was just me in the vehicle - brake failure on the highway put me and others on the road at major risk >Yes - After paying to diagnose, I was told this was brake master cylinder failure. ...GM issued a Customer Satisfaction Program (N202324120) for a limited number of MY2021 Silverado/Sierra trucks (mine is a MY2019) for dealers to replace the eBoost brake unit assemblies due to failure >Part has not been inspected by my insurance rep./I do not know if anyone else has inspected >The warnings illuminated on the dash at the time of brake failure while on the interstate 1. "Service ESC" 2. "Service Trailer Brake System" 3. "Steering Assist Is Reduced Drive with Care" 4. "Service Brake Assist" 5. "Brake System Failure 43 MPH Top Speed" 6. Also, the BRAKE, Traction Control and Engine lights illuminated
Service Brake assist is illuminated, Brake Failure has occured. Near miss on Busy street leaving parking lot.
Brake pad monitor listed over 90% for both front and rear brakes then all of sudden I get warning light that says Service Brake Monitor. I have had this happen twice since I purchased this vehicle new. The dealership has fixed it twice, there were software bugs. I cannot tell when I have a real issue or is it just a software bug.
When driving my truck I lost all power steering got notifications to service abs in 7 days, service esp, and service power steering as well as a stability at light being on. Could no control my vehicle, restarted the truck 4 times, and it disappeared, garage could not pull any codes. This is VERY unsafe!!!!!! And has been issued a recall in past models and years. I could have been killed, for a problem the GM is aware of and have not issued a recall yet.
When I began to accelerate my vehicle the brakes locked automatically. I noticed that once I hit 6 mph the brakes locked. I tried troubleshooting by turning the truck on and off, turning off all of the assistance buttons, turned the parking brake on and off. I was able to drive it in reverse.
Last Weekend was taking the kids and my brother and his son fishing, so 2 adults in front seats 3 kids on the backseat. Got my boat all hooked up and we're off. About 2 miles down the road the truck rebs up really high and then bottoms down hard on the RPM's. As soon as this happens all lights and instrument cluster goes crazy. Check Engine light on, Parking Brake Light On,Traction Control Light On, And I'm sure I'm forgetting more. The Cluster states ESC failure drive with caution, Do Not Exceed 43 miles per hour speed limit Brake Failure and So on. I have since found pictures pf the exact same thing that happened to me that morning and will provide. Needless to say I have no brakes and have a 19 ft bass boat behind me. All I could do was let off gas completely and push brake pedal all the way to the floor and pray that it stopped. Good Lord willing it did. Pulled over asap and killed truck, let sit a few minutes while I assessed the situation and cranked it back up. All lights and brakes were fine. Has not done it since but I only drove to dealership to find out the issue and 4 days later still no answer. Its a 2019 with only 26000 miles, and has never had 1 issue before this
The transmission on this truck it’s not good first they said it was the torque converter then they said it was the valve body ,it work for a few days and I told them before they change any of that that the transmission was making a rattling noise they just patching the problem not fixing the problem told them to give me a new truck or new transmission but they just keep patching the issue I been at cullman dealership like 7 times ,, also had a p25a2 code had a check engine light I told the dealership about and they didn’t do anything about it bc the check engine light wasn’t on anymore
