I was driving and a few different warning appeared. Service Parking Brake, Service Trailer Brake System, Steering Assist is reduced Drive with care. Along with these warning my speed was limited to 62 mph, my steering was reduced and my braking was reduced, all 3 of them to dangerous levels.
ABS light came on during breaking to avoid an accident and did not break the vehicle at all. Now there is a alert on the Driver Information Center(DIC) stating a break system failure.
The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while stopped in her driveway, the vehicle started rolling forward. The brake pedal was depressed aggressively several times however, the brakes failed to respond. After several attempts, the vehicle came to a stop. The vehicle was taken to the dealer where the mechanic stated that the failure could not be duplicated. The manufacturer was notified of the failure however, there was no response. The failure mileage was 14,562.
Vehicle had several lights on dashboard and messages, service brake system, engine power reduced, service trailer brake controller, service esc, service power steering. Vehicle lost power steering and brakes were nearly all impossible to push-??luckily I was near my house and got home safe, my family or myself could-??ve been seriously hurt

My 2020 Trail Boss recently had a break fail on the front right. The brakes are metal to metal and the brake sensor is reading 54% brake life left. GM says that there is only one brake sensor on the front of the truck and its on the right hand side. When I spoke to Chevy customer service I was told they have received several calls regarding this matter. Chevy service department is saying there is nothing wrong with any of the equipment, but I find it hard to believe that brakes wear this way normally. If they did I would think Chevy would have 2 brake sensors for each wheel.
I started my truck up and the dashboard warned me with service ESC and also Service Power Steering drive with care. Steering wheel was very hard to turn obviously no matter what way. I only got like 14,169 miles on the truck. I left it sitting for about 2 hrs. And it's supposedly back to normal. No lights some how.
While towing at a GCWR of over 29,000 pounds, my truck displayed the -??check trailer wiring-?? message on the DIC. I-??m glad that my vehicle alerted me to a situation with the trailer wiring, however, when this message is displayed it completely shuts off the brake output to the trailer brakes. It was incredibly nerve-racking and quite dangerous when traveling 70 mph down the freeway and then suddenly hitting traffic and realizing I had zero trailer brakes to assist me in stopping to avoid an accident. Once I was able to return home, I pulled the breakaway pin on the trailer and all brakes worked perfectly fine. I then pulled all the hubs on the trailer axles and found one brake magnet had wore down to the coil. Obviously this is an issue and needs to be replaced, but the fact that my truck cut break output to all the brakes completely is very dangerous and unacceptable. This is a serious safety issue since there is nothing that can be done while on the road to fix this. If I had been traveling in the mountains as I will be next week, this could easily have caused a much more serious situation. This situation has been discussed among other owners of the same vehicle who experienced the same situation. There is a message that comes up on the DIC, but at that point it-??s too late since the trailer brakes are already turned off by the vehicle. It seems to me that unless there is a serious short or the truck senses and extremely high amperage overload that it should continue work and send brake power to a trailer even if there is one single component that fails. That is the way that brake controllers have worked since they were invented, and now this new -??Integrated Trailer Brake Controller-?? is much less safe.
While driving home in my neighbor I was approaching vehicle ahead of me which was stopped. I applied the break pedal which went loosely all the way to ground and unresponsive. Due to my inability to stop on time I rear ended the vehicle. No warning that there was an issue with my breaks what so ever. The only thing that I did have going on was my trucks front panel (gauges & stereo screen) weren't functioning. I went to turn on my pick up and it behaved as if battery was dead. I let it sit for a few minutes and attempted to start it once again and it started right up. The issue was the stereo screen stayed black and only the fuel gauge and speedometer were functioning. In the end I ended up being at fault in the accident and reported it to my insurance.
Driving 50mph and the truck starts bucking, backfiring, and missing. Code appeared on the dash stating service ESC. Lack of Power steering and braking I parked the truck.
I was leaving work on May 17th and got in my 2020 Silverado and started the vehicle. Immediately codes were thrown on the dash stating that the power steering was out and that the ESC system needed serviced. The traction control system/ESC light was also illuminated on the dash. I was unable to turn the steering wheel whatsoever. I turned the vehicle off and restarted approximately three times all of which still were displaying the codes listed above. I let the truck sit for approximately 20 minutes and the codes had cleared themselves and the vehicle was functioning as it should. I immediately drove to the dealership and had it serviced. Dealership stated there was a programming issue related to the EBCM, which if I'm not mistaken was a recall already issued for the 2019 models. I have seen many instances online of this same issue occurring and sometimes impacting the ability to brake (if vehicle was in motion at time of onset). My onset occurred at approximately 14,000 miles while in park. Since the servicing (approximately 1 week) issue has not been replicated, but I am not sure if the problem has been fixed or if the computer is just functioning properly and will glitch again at some point in the future.
Multiple instances of service ESC, service parking brake and check engine light come on. The brakes are then affected and are tough to press causing the braking to be slowed down and the ABS kicked on while in motion.
Drove to work no issues no lights after work I start the truck check engine light is on service ebrake light is on and the ebrake light is flashing truck will not move ebrake is stuck on and I did not set the brake when I parked
In may I purchases a 2020 Silverado. On December 05th, 2020. I was driving on the interstate heading home from my son's football game. The "service brake system" message displayed on the vehicle's dashboard. Braking became sluggish and stiff. I initial thought the brake fluid had had leaked out. The vehicle maintained power to all other systems. Once home I checked the engine bay and brake calibers and found them to be intact. At this time the vehicle has 12,400 miles. After a initial assessment, was informed that it was determined to be a "computer glitch" that was effecting the transmission and brake sensors. The brake module was replaced and transmission "software" was updated. This was completed on December 09th, 2020. Upon completion the techs conducting a "drive test", at which time the warning appeared again. My vehicle remains at the service department, while they "troubleshoot" the problem. Due to the vague responses being provided by the dealership service staff and the lack of an estimated time line for the completion of the repairs. I believe there is a much larger issue that they don't want to reveal.
Traveling at about 75-80mph, on a highway, - brakes engaged, slowing vehicle by about 15mph causing the truck to jerk as if it missed a gear. "service ESC" diaglogue, traction control light, and check engine light came on.
1st occurrence, 9840 miles- slowing to stop sign, about 10mph, truck jumped violently, felt like I was rear-ended. Service parking brake, service ESC, traction control off messages and cel on. Stuck in gear. Restarted truck, resumed normal operation but cel remained. 2nd occurrence, 9865 miles - 65mph on highway going around curve, truck jumped violently causing rear end to break free slightly, though I kept control. Transmission now several gears lower and stuck there, turning 2400 RPM at 65mph. Same three warning messages and cel. Tried manual transmission mode, but it displayed no gear indication, and the +/- buttons did nothing. Pulled off highway, restarted, all messages went away, cel remained. Truck resumed normal operation. 3rd occurrence, 9905 miles (on the way to the dealer) - I was stopped at traffic light, first in a string of cars. Light turned green, I started to accelerate, just into the intersection, truck jumped violently, same warning messages, still had the cel from the last time. Truck was now stuck in a higher gear, could barely get through intersection. Vehicle behind me narrowly missed rear-ending me, and others were blowing horns as I limped to the far side of intersection. This is a massive safety concern. If any of the above scenarios had occurred on snowy/icy roads, I could have injured or killed someone, including myself and/or my [xxx] year-old. Dealer replaced tcm, but is still noting "loss of communication" codes being generated. A Chevy engineer has requested them to investigate the wire harness for damage in a particular location, suggesting Chevy knows of a manufacturing issue. If that's so, and Chevy hasn't issued a recall - or even a tsb - then this poses a strong case for negligence on their part. Are they waiting for someone to get injured or die before acting on this? I've now been without the truck for 10 days. Parts of this document have been redacted to protect personally identifiable information pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B
When foot brake and emergency brake is released and truck is put in D position, loud pop is heard and truck lunges forward all at once with no exceleration. Chev dealers in area won't see vehicle for over 2 weeks even with safety recall out. Trip cancelled. Never buy a chev!!!
2020 Silverado 1500 custom crew cab 4.6L, V6. Purchased truck onaugust 10, 2020. Took it to dealer on August 17, 2020 because of jerking forward at low speed (20-25 mph) and rear brakes making a deep rubbing sound. Of course, technician said there were no problems (because he could not duplicate) the jerking motion. After picking up my truck, I noticed that they did not even address the brake issue, nor did the service advisor note it on the form.
Was on vacation and went to eat supper approximately an hour later returned to vehicle cranked up truck and went to leave (in reverse) when I cut the wheel the truck had no power steering and so I pressed the brake and it was barely working, luckily I wasn't going to fast and was able to stop before hitting the vehicle behind me. Check ESC light came on. Had to disconnect the battery to reset the computer
