Trailer brake controls not working. Safety at risk due to electric trailer brakes not working. Other lights and functions work when trailer plugged in.
The contact owns a 2020 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the trailer disconnected from the tow hitch. Additionally, the trailer brake warning light was illuminated. The vehicle was taken to the dealer and brake switch was replaced; however, the failure recurred. The vehicle was not repaired. The contact related the failure to GM PIT: 5948A. The manufacturer was made aware of the failure. The failure mileage was approximately 2,000.
I drove approximately 8 miles to lunch and parked the truck. It sat about an hour and when I started the truck to leave I had a message to service esc and power steering reduced. The tuck had no power steering. Returns to work and the truck sat about ten minutes. Then everything started normal and is fine.
Brake system failure. While driving vehicle, brake system and traction control stopped working. Vehicle was then limited to 62 MPH. Almost no braking available and pedal needed to be pushed very hardly to the floor.

First I I-??d notice my pedal kick every once in a while then pulling into driveway all warnings kicked on and truck was hard to stop almost hitting garage. I got engine light, traction control light, and brake light, service ecs, brake system failure 43mph max speed, service brake assist
Purchased the truck through CARMAX and two weeks later received the -??Service Brake Assist-?? and -??Brake System Failure-?? message on the Console. This has happened twice in in one month.
The Advanced Trailering system will fail to load, preventing the user from entering the correct vehicle being towed and the entire system screen is blank and won't load. This could be a huge safety concern if the driver cannot select the correct vehicle being towed since the Brake Gain is stored in the Advanced Trailering system and then the incorrect amount of braking force will be applied to the vehicle while it is being driven, which could cause insufficient or excessive braking forces applied to the towed vehicle. This could lead to rear end crashes or Jack-Knifed crashes. The problem is random but repeatable quite frequently and has been confirmed by the Dealer (refer to included GM Bulletin PIT5792 Published on 11/5/2020) GM has been aware of this problem for almost 2 years and has not provided a fix for it. I have had this vehicle in the dealer on at least 3 occasions to fix the problem There is no advanced warning, message or other symptom prior to this problem. The problem started within a month of purchasing the vehicle
My truck had been randomly misfiring but the dealership couldn-??t resolve the issue because the check engine light would go away on the way there. They were able to pull codes showing a misfire taking place and told me to return if it continued. The truck started having misfire issues again periodically fir the next 2 weeks but once the check engine light stayed on I scheduled an appointment. On the way to the appointment to Hidiburg Chevrolet we were on the interstate the cruise control kicked off, the service parking brake indicator, misfire flashing of check engine light, an ESC warning, and the traction control light came on as the truck randomly pulled to the right real quick then it stopped. Once the indicators went off all warning indicators were off and cruise control would not work. The dealership pulled codes and saw every cylinder misfired and that the other issues that took place. They tested everything and could not find the source and said that they had to wait until the indicator stayed on so they could see the issue. I left with no resolution and concern that when the misfiring could damage parts and the computer. I also fear that the issue if someone isn-??t aware of vehicles not fixed could lead to severe accidents and potential for death if not fixed.
As I was backing out of a parking spot in a lot my vehicle lost it's power steering. I got an Service ESC error code, a wrench indicator, and a service power steering/drive with care warning. I also got a diagnostic alert from On Star. Diagnostic Alert: Service Antilock Breaking System in your 2020 Silveragod pithing the next 7 days. I was unable to move steering wheel, and could only pull my vehicle forward. So it was stuck sideways in the parking lot for about 20 minutes. My car did restart again and the code cleared. I was able to drive it to the dealer. They ran diagnostics but were unable to duplicate the concern. They did find a history of 1 fault where several modules (ECM, EBCM, TCM, TCCM) had lost communication with the power steering control module. They also looked at Data Com schematic doc 5257308 and found modules before connector X182 had lost communication. My safety was a risk in this situation because I was stuck sideways in a parking lot with very limited ability to move my vehicle for incoming or outgoing traffic. Had this happened while I was driving the vehicle in a roadway I believe it could have caused an accident. The dealership did find that a harness was making contact with the upper control arm bolt. They re-taped the harness and secured it away from the control arm bolt and bracket. A new bracket was ordered.
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
The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while driving and attempting to accelerate, the vehicle shutoff without warning. The vehicle was taken to the local dealer where it was diagnosed that the computer module was faulty. The vehicle was repaired. Additionally, while driving, the brake pedal was depressed however, the vehicle failed to respond. The vehicle revved and there were several unknown warning lights illuminated. The vehicle was towed to the same local dealer however, the mechanic was unable to duplicate the failure after performing a test drive. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure but no assistance was provided. The failure mileage was approximately 16,000.
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.
