2020 Chevrolet Silverado 2500 brakes problems

Filed Oct 25, 2026 · Brakes, Electrical · AK

Trailer brakes keep disconnecting and connecting . Warning pops up on dash to check trailer connections. I may not happen for a hundred miles or does it 10 or 12 times in just a few miles.I've seen several complaints from on line reports but no solutions from GM yet. Very frustrating when trying to pull a trailer.

My dash has been displaying intermittently “Service electric trailer brakes”. I have recently purchased a 30’ travel trailer. After driving a couple hundred miles with trailer in tow. The code started appearing even with the trailer not connected. I have contacted GM and they have indicated no recall on electric brake controller.

Rear wheels locked up while driving/accelerating. Happened 5 times, 4 times while towing a camper once without towing. Luckily no harm or damage came to anyone. Traded in at dealership due to safety concerns after no diagnostics found anything “wrong”. It is already listed for sale, but I don’t think It’s been addressed or fixed.

I own a 2020 Chevrolet Silverado 2500 HD pick-up, VIN: [XXX] . I use this truck primarily to haul a heavy horse trailer and to tow a travel trailer. Ever since I bought this truck I have had a problem with the trailering application. At times it will start working (especially if it has not been used in a while??), but every time I am actively using it there is an issue: •The app will totally blank out giving me a black screen, and/or •I will get a message that my trailer brakes are disconnected. I will stop, disconnect and reconnect the brakes, turn off the engine and restart, and so on. Nothing helps. I have had my truck in to the dealer (Bend Chevrolet) three times to have this repaired. Every time I get the reply that there is nothing they can do, that Chevrolet says this is a software issue and that they are working on it. See Bulletin [XXX] Trailering App is Non-Functional, published 11/5/2020. Chevrolet has been aware of this problem for over 3 years and has not come up with a solution? This feels like they are ignoring it. I have searched on-line and see that many Chevrolet Silverado owners have the same problem and are getting no assistance in solving it. For years. This is a safety problem. I haul in mountainous terrain and cannot afford to have issues with my trailering system, especially the brakes. I would like to see the federal safety agency issue a recall on this problem and demand that Chevrolet fix it. Please contact me if you need additional information. I would really like to get this fixed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I purchased this vehicle brand new from Lunghamer Chevrolet in Pontiac, MI. I park my truck on a hill every day and as of around a week ago the emergency brake system won't disengage properly. I know it has been engaging since, my gas milage has decreased significantly. Then, a warning light came on the dash, so I took it to Wally Edgar Chevrolet in Lake Orion for diagnosis and they told me that the actuators and wiring harness need to be replaced. They said that there seems to be corrosion on the connector to the harness, and the actuators need to be replaced. Since, my warranty is expired they will not cover the repairs and they quoted me $2,125. I only have 48,428 miles on this vehicle! If the emergency brake is engaged, couldn't it completely stop my vehicle without warning? I drive the highway every day! Isn't this a safety concern? I don't go off road, I don't abuse this truck and I keep it clean as much as possible! Yes, I live in Michigan but, GM has been producing vehicles for quite a long time and I cannot believe they can't keep the wiring connector from corroding. I also went online to see if there were others that have experienced this, and I found one owner of the same model that had to fix it twice! [XXX] . I'm sure I could find more complaints but, I stopped there since I am so disappointed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Numerous times since first taking possession of new vehicle trucks electronic emergency braking system has activated while driving all on its own without warning. several times while on slower side roads and several times while at Interstate speeds, twice coming very close to a head on collision and once coming close to being rear ended while towing a car on a trailer by a semitrailer. The last time there was a message on the drivers information center that stated "service parking brake" The truck has been out of service use to several dealers to diagnose the problem to no avail. I've explained to the dealers its like having a blown tire, you can't predict when it will happen. Its a very dangerous situation. Second the goodyear wrangler tires tend to slide on curves in wet weather. This happens whenever the road is wet and you are on a curve. Both these defects have been reported to the manufacturer as well as servicing dealers. Very dangerous truck.

Brakes are grinding and squeaking. Sometimes does not seem like it will stop. Chevrolet dealership says its a wearable part and nothing they can do. Brakes are not supposed to grind and squeal. Brakes have done this since brand new. Contacted Chevrolet about the service bulletin on the web Bulletin 20-NA-020. They state they can't help me and its not covered. It Cleary has all the descriptions and symptoms of their bulletin. I made a formal complaint 9-9864406840. I just wan to be sure if something happens I am not held accountable for a manufacture that has a known issue but choses not to fix or be responsible for using bad parts.
