2022 Chevrolet Silverado 1500 Brakes

Service brake assist message on dash, with check engine light. Brakes are almost useless takes excessive force to get vehicle to stop. Resets after being parked and restarted. has happened several times but will not replicate a dealer. Started with less then 2500 miles on the truck.

Brake failure warning notification and brakes went soft without warning. Almost rear ended vehicle in front of me.

A wire box fell down from behind the dash, and landed behind the brake pedal. This created a severe emergency situation in that the brake pedal could not be depressed at a traffic light, almost causing a car accident. The dealership explained that they have seen this problem before, but it's not a current recall, but should be. I've also been in contact with GM Customer Care [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle emergency/parking brake actuators failed which could allow the vehicle to roll-away unexpectedly or render this safety braking system inoperable in time of emergency. There is a TSB number PIT 5662G, dated March 25, 2022 that covers testing to confirm defective actuators. This is a known defect to Chevrolet and as it impacts a vehicle operating safety system should be subject to a recall.

Started my truck and drove off. 10 seconds later all of the lights on instrument cluster came on and displayed steering assist reduced the. It said service brake assist. My brakes weee very spongy and hardly worked luckily I was only driving 20 mph and no one was in front of me. I had to disconnect battery and reconnect to fix the problem. What if I was on the highway doing 70 mph and had to hit my brakes suddenly. Someone or multiple people could have been injured. This truck has 13,000 miles on and it’s a year old. I have ready many reports online of this happening in earlier models. How can car manufactures get away with this ?

Error message states, trailer brakes disabled service required As your towing truck will disable trailer breaks took to gm dealer and simply stated there is no fix right now. This is unsafe when in tow to not have trailer breaks. Gm know and dealer hasn't fixed new truck tons of gm bulletin on this issue.

Integrated trailer brake failure. Pugged in trailer and received message stated trailer brake failure, needs service

Trailer brakes disable with any trailer being plugged into. GM has a service bulletin but no fix. It is not a plug issue either. I have tried 7 different trailers on my truck.

Trailer Brake Controller, yes available for inspection Randomly deactivates Trailer brake controller, Causing hard stopping when needed. Yes problem can be reproduced - has been confirmed by GM, they say they have no fix. Yes unit has been inspected by certified GM dealer, They say there is not a fix. Warning lamp came on same time, it quit working.

My truck randomly stops activating the trailer brakes! This is a major safety problem! They are not doing anything to fix it!

The integrated trailer braking system will function momentarily and then disable entirely while towing a trailer. This is extremely dangerous as it will not allow the vehicle to come safely to a stop if needed. Emergency braking would be greatly hindered without functioning trailer brakes. GM knows of this problem and "Does not have a fix". See attached dealer description. This is not an isolated incident.

Trailer brake system is not working. Vehicle is reporting trouble code C159C and is subject to service bulletin PIT5948A per the dealership. The latest update states “GM is aware of the issue and is working on a resolution”. The latest update is almost 3 months ago. I have an active case with GM on this. Case sr:9-8884642509. They gave me a $300 credit to my Chevrolet account to purchase chevy parts however I want my truck working. Not being able to use the trailer brake system is very dangerous when towing and the fact that this is a $60,000 truck that I literally bought to tow my camper and can’t even tow with it safely defeats the purpose of my paying for this truck.

Purchased 2022 Chevrolet Silverado 1500 new on 10/4/2022. First used to tow on 10/7/2022 with less than 500 miles from new on vehicle. I hooked up our brand new camper (1 month old 2022 Grand Design Imagine) to the truck and the integrated trailer brake controller for the first time and a message appeared on DIC stating "Trailer Brakes Disabled Service Required" and the trailer brakes disengaged. Restarted vehicle and the message west away, only to come back on the first time I applied the brakes. Dealership service department has been helpful in as much as they have evaluated both my truck and the camper. Found the truck integrated brake controller was not communicating properly and had a DTC of C159C. Dealership tested camper trailer brakes and found them to be working properly (as expected). Dealership service department states GM knows about this issue and has no known correction to the issue. They are keeping an open service ticket on this issue. In the interim the dealership service department has installed an aftermarket trailer brake controller so I do have trailer brakes until GM solves the issue.

When driving with a trailer connected to the truck, the DIC displays Trailer Brake Disabled Service required. Power to trailer brakes immediately ceases and the truck brakes are left to stop the truck and trailer. This is extremely dangerous for heavy loads at high speeds. Almost caused an accident due to this issue. Unable to use truck to tow out of fear for safety. Trailer was tested and inspected. Trailer was also used by another truck with no issue. Connected the truck to a different trailer with brakes and the problem replicated with the other trailer.

GM is rolling trucks off the production line with a known trailer brake controller fault. This issue causes the truck to lock out the trailer braking function immediately after applying braking with a trailer attached. This causes stopping distance to be dramatically increased resulting in greater risk of an accident. GM needs to correct this issue before loss of life occurs. This seems to be wide spread. https://www.gm-trucks.com/forums/applications/core/interface/file/attachment.php?id=166822&key=85381e43bf444ec4cbd8ddc48e53190b

On 11/10/2022 I was driving in moderate to heavy traffic at low speed; approximately twenty (20) mph. I applied the brakes and immediately experienced a hard pedal coupled with some pulsating. I pressed the pedal as hard as I could as there was traffic stopped in front of me. At the same time every warning light illuminated on the dashboard. My truck stopped just short of colliding with the other vehicle in front of me. The message displayed on the dash read “Brake System Failure” followed by a second message which read “Trailer Brake Failure”, and then an additional message that read “Do not exceed 42 mph”. Fortunately there was a Chevy dealership nearby. I drove the vehicle at very low speed to their service department and currently wait a diagnosis. My Chevrolet app also sent me a text at the time of the incident which read “Diagnostic Alert: Service the Antilock Braking System in your 2022 Silverado within 1 day”. My experience is similar to another incident which was reported to your agency in September of this year involving the same model truck. Note: I was not pulling a trailer at the time of the incident.

This vehicle has integrated electric brake system. After hooking up Homesteader Hercules trailer, went through all settings, adjusted brake gain, brakes worked for 1 minute, then alert appeared "trailer brakes disabled" "service trailer brake system". This is an ugent issue; the trailer is a 6x12 dual axle and the electric brakes are essential. The Silverado ZR2 is a heavy truck, but depending on only the truck brakes on wet pavement could be disastrous! The dealership has been notified and will run a diagnostic check on it. But, one of the reasons I purchased this truck is the fact it came with the electric brake control system factory installed. (ZR2 only has 237 miles on it currently)

As I was driving my vehicle on 9/12 the truck reported a brake system failure and I lost power to my brakes. I was able to pull over at the gas station and call the dealership. They said they couldn’t assist because they didn’t know what the issue was. I called a tow truck and had it towed to the dealer. They had my truck for 8 days and replaced the brake module and gave me back my truck. I noticed that the truck had only moved 1 mile from the time I left it at the dealer. NO ONE TEST DROVE THE VEHICLE prior to giving it back to me. As I was driving home on 9/20 my brakes failed again and I lost power. The dashboard read “Brake system failure “. I called the dealer and this time they towed the vehicle. They said they are replacing the entire master cylinder but I don’t have faith that this will solve the issue. I’ve heard of other Chevy Silverado’s with the same issue at the dealer in Saint cloud and OBT. I’ve reported this to GM HQ and it doesn’t seem like there is a sense of urgency or that they care about the safety concerns I have with this truck… I do not feel safe in that vehicle and need your help. The first file is from 9/12 and the second file is from 9/20. See attached

The integrated trailer brake system will quit working mid tow. The warning something along the line of "service trailer brake, trailer brakes disabled" comes on and at that point I no longer have use of the trailer brakes while towing. This is very unsafe as I am regularly towing 4000-6000lbs. GM does not have a solution to the problem at this time and has been no help resolving the issue. I have been told "hopefully there will be a solution soon."

Started vehicle and all of the brake system warning lights were on. Vehicle stated that I could drive 43 mph with limited braking ability and limited steering. Basically the power assisted brakes and steering would not work. The vehicle was parked at my place of employment. Called the dealer to ask for suggestions. Ask discussing it we decided to take it to the dealership. That was a good idea as there was not enough braking power to stop the pick up in an emergency situation. It took all I could to get it to stop. Pedal to the floor and hold it tight. The Service Manager decided it should stay as driving it was terribly dangerous. I was told it needed a new ECS. The vehicle shouldn't be driven in this state. What if this was to happen on the highway while pulling a trailer. This would put the driver, passengers and others at severe risk. Something needs to happen. Once it's fixed do I even trust it anymore?? GM KNOWS ABOUT IT
