2020 Chevrolet Silverado 1500: brake failure

Filed Nov 2, 2026 · Brakes · OH

Was driving for about an hour pulling our 7,000 lb camper when all of sudden my daah lit up with all kind of lights and warnings. The messages were Service Trailer Btake System, Service ESC, Service Parking Brake, Brake System Failure 62mph top speed, check engine light, Traction Control Off, ABS Off. Pretty much had no brakes and had to use the manual gear selection to slow down from 65 mph. Not a good feeling wh no brakes pulling a camper. The brake pedal was hard and used everything I had to get it to go in to try to stop. Now my rear brakes on the truck currently making all kind of noise and the truck went to the mechanic today.

It said on the dash, "Brake System Failure 43MPH Top Speed," "Service ESC," and lights on were the ABS light, BRAKE light, Engine Light, and Wheel Traction light. My wife and my [XXX] son's safety were at risk while driving on a busy 75mph highway and trying to turn around and make it home as the brakes did not work and having to cross busy streets. It was not able to reproduce but my local mechanic found the bulletin from way back that had not been addressed by GM after numerous times to a dealer for other repairs. I then took it to a local GM dealer that confirmed software update was not applied and they did the repair and I was charged to pay even though this was a known GM issue that never contacted me about this potential fatal random occurrence that could happen after I have taken great care of this truck. There not any warnings before randomly losing power on the highway once she hit 60mph on the on ramp and just started failing slowly.

Intermittent issue where info says brake failure/steering assist not working/limited speed to 43 mph. Very dangerous if you’re on the interstate. Becomes hard to steer, brakes don’t work, brakes start burning up. Have to carry tools with me to reset ecm. Very common problem with Silverado with 5.3 gas engine. Chevy needs to fix this issue before someone gets killed. I would give them my truck back if I could.

While driving home from work the truck displayed numerous trouble codes including ebc failure, braking failure, traction control failure and trailer brake failure as well as vehicle governed to 42 mph. I took it to the dealership and they checked all of the braking system and could not find any issues. They reset the codes, and changed all 4 pads and rotors as all 4 wheels were 1/32 out of true as a precaution. I drove it home about 5 miles with no issues. The next morning I was on my way to work and the codes reappeared with me being governed to 62 mph. At the stop sign I had no braking at all. Pumping the brakes resulted in no braking or pressure in the pedal. Luckily there was no traffic and I was able to use a hill to stop. I turned around and went the mile back to my house and was unable to stop again ending up with the front end in my neighbors yard. I had the vehicle towed back to the dealership where they still have not found a cause or a solution to the issue

After driving and doing errands I tried to pull truck into garage and noticed it was hard to move. It seemed like brakes were stuck on despite not applying brakes. I pulled out of driveway to drive around block. Lost all brakes while driving down county road at 50 mph. Check engine light on, brake failure warning on, warning light that speed limited to 43 mph, ABS light on. Eventually able to stop. Turned off engine for a few minutes. Restarted and brakes all worked again although check engine light still on. This could have been deadly on a steep road or on ice or in traffic. I see online that this is a common problem with Chevy trucks although no recall has been issued for this one. I am very concerned that this truck is not safe - for me or anyone else on the road with me. I have not taken it in. I live in the country, some distance from a dealership so nothing has been confirmed. Nothing like this has happened to this truck before and there was no other warning. It is available for inspection but is my only transportation.

This morning it was 16 degrees F I drove about 6 city miles at about 35 mph. I was 1.5 miles from home when leaving a stop light the truck bogged down and was only going up to about 25 mph with the tach at 2000 rpm. It seemed at first that I was driving with the parking brake on but most V8's have enough power to override the parking brake. This acted as if I was pressing hard on the foot brake while driving and giving it a lot of gas. I probably would have had to floor it to go any faster. But was afraid of damaging something. Put on the flashers and drove about 15 mph with the tach at 1500-2000rpm. The dash displayed "Brake system failure 62 mph top speed", "Service ESC", "Parking brake failure" and "Service trailer brake system", The brake pedal was changing its height by itself. Pulled to side of road and pumped the brakes several times, shifted the transmission through park, neutral, reverse and drive and it seemed to operate normally. Pulled onto road and it was bogging down the same. Pulled to side of road again. Then started driving again with flashers on and the tranny shifted as normal, but the brake pedal went to the floor. Pumped the brake pedal and it still went to the floor. Drove slowly while checking the brake occasionally but still went to the floor during the 5 blocks to my driveway. The brake had no effect. My driveway slopes slightly upward so I stopped safely. All four wheel centers and brake rotors were too hot to touch after slowly driving the 1.5 miles this occurred over. About 15 minutes later I turned on the key and the dash displayed "Brake system failure 43 mph top speed", "Service ESC", and "Service trailer brake system". Fortunately there were no vehicles close in front of me when this started and many were behind me when driving with my flashers on due to quite a bit of traffic. This could have been a disaster had it occurred somewhere else. The local Chevrolet dealer that services it has not seen it yet.

First incident was when the vehicle had under 7,000 miles. Transmission module went. Vehicle wouldn't move. A few months prior, when we pulled our camping trailer, the integrated brake didn't work and the truck brakes overheated. Took vehicle to dealer, couldn't find a problem. A few months later the truck would not move, and found to be the transmission module. After a month and they finally got the part and repaired, no problems with pulling the camper. Than last week, we pulled out on the road, and we couldn't accelerate. A little over 45,000 miles on it. Had towed to dealer, they have diagnosed Transmission Valve Body. No warning lights. Maybe the transmission was hesitating some before it went. Waiting for the part, which no clue how long it will take.

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: [XXX]. Cost: $125.69. Mileage was 53,531. On [XXX], 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.

vehicle has approximately 45k miles, We were 2.5 hours away from home on a paved highway driving 55mph and the front passenger side ball joint failed and upper control arm separated also Instantly no brakes causing an accident . This is very dangerous and is going to kill people , we are lucky we didn't roll . I'm now afraid this will happen to the other side? chevy will not take the responsibility to fix it , our extended warranty only covered the upper control arm and not any of the other parts that had damage due to the ball joint . it was a 2.5 hour tow as well . Also the tow truck driver said within a week this was the 4th Chevy truck with the same issue 2 of them Rolled .
