The contact owns a 20120 Chevrolet Silverado 1500. The contact stated while driving at 30 mph, the service brakes were inoperable. The contact depressed the brake pedal all the way to the floor board and the vehicle did not stop or slow down. The contact stated that several warning lights were illuminated. The contact stated that due to the service brakes being inoperable, he tried to avoid a crash. While the contact was making a left turn, an oncoming vehicle crashed into the vehicle on the right rear side of the vehicle. The contact stated that the vehicle continued to roll while he continued to depress the brake pedal and the vehicle finally came to a stop. The axel was fractured and the frame underneath of the vehicle had shifted. The vehicle was undrivable. The contact and the other driver contacted the local police and the incident report was taken over the phone. No injuries were reported. The contact stated that the failure had occurred previously, and the dealer was made aware of the failure. The manufacturer was made aware of the failure and advised the contact that a tow truck would be picking the vehicle up. The failure mileage was approximately 82,000.

Truck shudders, with varying degrees of vibration, emtek applying brakes. It is especially rough when applying brakes on the highway as it feels like it could lose steering control. Shaking is also very noticeable at slow speeds. Have had rear brakes serviced and problem persists. As of this month, the "service esc (electronic stability control)" light has come on, along with other faults on the dash. VIN does not indicate unrepaired recalls, but this issue makes the drive feel dangerous.

Brake calipers on 3 of 4 wheels are trying to lock up. Only 54000 miles on the truck this should not be an issue. Could kill someone.

Around 35k miles had an engine lifter fail and needed to be replaced, covered under warranty. 07/2023 - had front pads/rotors replaced by chevy dealer and had loud squeaking ever since. Contacted dealer and was told they are new pads so will just need time to break in. Contacted the dealer again in sept. Oct. 2023 and brought vehicle in for service for noise concern. They informed me the noise is coming from the rear brakes that was reported as 60% life two months prior. They replaced the rear rotors/pads and noise persisted. Brought vehicle back to dealer in December, they performed a serviced but was ineffective. In March 24 started getting some vibrations when stopping. Brought vehicle for servicing, stated there are rust spots on rotors but everything is wearing fine so this will not be covered under warranty. Also that they do not warranty sounds due to pads can have more metallics then others and they cannot determine which ones do not. I looked under forums and gm pads seem to be a common issue with noise. My truck was perfectly fine before these brake products were installed and I would like gm to be held accountable for there inferior products leading to loud break noises and violent vibrations while braking !.

Vehicle is at 67,xxx miles. Vehicle is losing power, check engine light, service 4wd, service esc, service power steering, service parking brake. . . . . The gas pedal has locked on me already with my 3 small children in the truck at highway speeds. Gm says it's fine. I have all the work orders where 2 different dealerships have "corrected" these issues under warranty. Go retrieve the vehicle and within a week vehicle is back acting up. This truck is unsafe to drive on the roadway. I have not been offered a courtesy vehicle to drive while "warranty" work is being done. I am appalled and in fear for my children and my own life with this truck.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that while depressing the brake pedal to stop the vehicle, there was an abnormal squealing sound coming from the front of the vehicle. The vehicle was taken to the local mechanic who replaced the front brake pads. While test driving the vehicle, the front driver’s side brake caliper failed. The cause of the failure was not yet determined. The manufacturer was contacted, and the contact was informed that the vehicle was not included in NHTSA campaign number: 20v116000 (service brakes, hydraulic). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 37,000.

Was riding down the road and my front left caliber locked up had break fluid running down from the upper reservoir the truck only has 46,000 miles. The truck was immobile had to have it towed and had to get a new caliber and took the shop almost a week to get air out the system breaks are still not 100 percent also rear breaks are having a problem fully releasing as well. Leaves me worried the rear breaks will seize up as well cost me 1000 dollars for the repairs.

Trailer brake controls not working. Safety at risk due to electric trailer brakes not working. Other lights and functions work when trailer plugged in.

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.

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.

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.

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.

Power train transmission torque converter “chevy shake” multiple symptoms. - shuttering , “ buffeting” , slipping sensation. Continuous almost like “strong wind gust” or “head wind” - humming, if you have ever heard a “high pressure” hydraulic equipment. - rpm bounces 300 to 500, but transmission does not “down shift” (while driving) - vibration, of the truck can be noticed, felt at various speeds, 40mph to 60mph(shutter) almost like it struggling to get up to speed (unless heavy on the gas pedal) 70mph and above to say 80mph, then shaking, vibrations worse when coasting back to 70 mph vibration will “not stop” until truck speed is drastically slowed or come to a stop. - steering wheel “shakes” , “vibrates” also can happen at 60mph to 70mph and above to say 80mph, then worse when coasting back to 70 mph - “clunk” when stopped and shifting into “reverse” (new development symptom) vehicle is in for inspection. It keeps reading service break system. Service esc.

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.

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.

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.

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.

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.

The contact's husband owns a 2020 Chevrolet Silverado 1500. The contact stated that while her husband was driving at approximately 65 mph, the vehicle suddenly decelerated to 40 mph. The contact stated that the failure recurred on various occasions and that an unknown warning light was illuminated. The vehicle was taken to a local dealer, where the failure could not be duplicated. The failure reoccurred and the vehicle was taken back to the dealer, where it was diagnosed that two brake calipers needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the dealer, where it was diagnosed that the brake master cylinder needed to be replaced. The vehicle was repaired; however, the failure persisted. The vehicle was then taken to classic chevy sugar land (southwest fwy, sugar land, TX 77478), where it was diagnosed that the brake master cylinder needed to be replaced again. The VIN was not included in NHTSA campaign number: 20v116000 (service brakes, hydraulic). The vehicle remained at the dealer awaiting the repair. The manufacturer was made aware of the failure and the contact was advised to file a complaint with the NHTSA hotline. The failure mileage was unknown.

Esc light comes on brake systems failure max speed 62 mph and tralier brake systems. Abs light , engine light, traction light all come on.

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.

The vehicle was repaired. The manufacturer was not notified of the failure. The contact was concerned that both failures were connected. The failure mileage was approximately 15,000.

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.

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.
