Automatic Emergency Braking problems of the 2020 Chevrolet Silverado 1500

Brakes lock up on vehicle while driving must turn vehicle off and restart several times to disengage brakes. This has happened twice in the last 8 weeks, very concerning as we cannot use our travel trailer as we do not trust this not reoccurring. Chevy dealership says there is a recall on this issue but not on my truck?. But they say it is that problem.

Brake failure. I took the truck to the dealer and was told not to drive it. The dealer ran two checks and then said brake failure. The rep had to leave, so another rep put my car in the shop overnight. The next day, I was told in writing that they could not find any problem. The code clearly showed brake failure. Date: oct. 16, 2024. Cost: $125. 69. Mileage was 53,531. On November 25th, another brake failure. I went to an auto parts dealer (o riley) in topeka, KS, and they found a brake failure code(I have a copy). They told me to go to the dealer. I went to the dealer with a stiff pedal, which means driving is very unsafe. The dealer said too busy with oil changes and told me to return another day. I said no breaks.

We went to an appointment and when we got back in the car, a message was on the screen. It said that the brake system has failed and we could only drive 43 mph maximum! the engine light was on and we could not accelerate beyond 43 mph. This is extremely dangerous when driving on a highway! we drove home on the interstate going 43 mph in a 70 mph zone! we had small children in the car and almost got into a few accidents due to other aggressive drivers. We then called local dealers who said that they were too busy to take our truck for weeks! they also said that our truck was not covered under warranty. So we took it to a local body shop. They fixed it for just above $500. It worked for a week and broke again, then they fixed it again for free. The brake failure 43 mph light came on for the 3rd time. We took it garber and they fixed it after 2 weeks and charged us a fortune. Invoice attached. A few weeks later the same light came back on. Garber then took another 2 weeks to fix it! I’m writing here as I’ve seen other silverados recalled for the same issue but not my exact truck (year). It’s obviously faulty software and it should not be the customers responsibility to fix. Especially with a vehicle under 20k miles! there is absolutely no way that we will ever buy a gm again but the important part here is that other people are not put into a dangerous situation like we were. Besides dealing with this issue for well over a month - the important part is safety. I can’t understand how these trucks have the same problems but only certain vins qualify for a recall. Please consider our truck as part of the overall recall for this issue. It’s unethical to pick and choose only certain vins!.

Problem started while driving on the highway, I was speeding up from the ramp to merge into the highway. As I got to 62 mph the dashboard started blinking that I could only go up to 62 mph max. Cruise control was not on. I drove to my destination at that speed with the message on the dashboard. I arrived at my destination, parked, turned it off, a couple of hours later turned it on to drive again. At this point, the dashboard message was that I could only drive it max speed 42 mph and "service tire monitor system" I towed to my mechanic given I could not drive at that speed on the highway back home. The mechanic said it was time for a brake change and that might be the issue. He changed all the brake pads and rotors and the truck drove fine again for less than a week. As I was getting on the highway, the truck started to jerk like it wanted to stop as I was speeding up, I was going 45 mph. There was a clanking sound coming from the engine. Then multiple things started flashing on the dashboard; check engine, traction control, messages reading "service parking brake" and "service esc" I turned the truck off for a couple of minutes on the highway shoulder. Turned it back on, the same messages were still on the dash. I again could only drive it max in the 40's mph. The faster I tried to go, the more heavy and forced the truck felt. I had to park it over night in a parking lot. The next day I scheduled an appointment with a mechanic in town who checked it and said I would be needing a new engine, that he had seen this same problem a couple of weeks ago on a same truck. He quoted me $9k. I towed the truck back home and had another mechanic come take a look at it, he was getting the codes 0p50d and p0304. He exchanged the 4 cylinder for the good 1 cylinder to see if the codes would change from #4 to #1 and it did not. He said the issue was internal at that point and suggested I go take it to the dealership under the warranty. Its not under warranty, it ended at 60k miles and I have 80k now.

Brake system light failure. Some system lights came on. I had no breaks car didn’t stop fast enough before hitting a pole.

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.
