2022 CHEVROLET SILVERADO 1500 Complaints

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.

The adaptive cruise control does not maintain a safe gap to the vehicle in front in order to slow down or stop to avoid hard braking and/or collision. This is especially true when approaching a stopped vehicle, the adaptive cruise control continues at the speed selected and brakes really hard causing the collision warning to activate.

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.

While on vacation, Engine light came on , returned home due to excessive DEF usage, poor fuel mileage and heavy deisel smell in cab. Brought vehicle in to Gerry Lane on 11/8/22. *Was told 7-10 days to get parts an not to drive, May Catch On Fire due to an open exhaust. (Concerned because we drove home over 1,200 miles). From Service Advisor.. Our tech found the number exhaust gas temperature sensor missing from the diesel particulate filter and catalytic converter assembly, likely blown out due to excess pressure in the system. We’re going to replace that sensor, the DPF/converter assembly, and the relevant seals, gaskets, and clamps for that repair.

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.

One week prior to the incident my engine had a loud ticking/knocking noise when starting up especially on a cold start, one night before thanksgiving driving to California I had my truck on cruise control 80mph when suddenly without any warning the engine shut off! My touch screen and speed gauge were still on I tried pulling over as quickly as I can with my emergency flashers on, I was almost side struck by trailers passing by me doing so! My truck got towed to the nearest Chevy dealer where I was told it was an electrical issue at first, then 3 hours after that call the service team called again telling me they have found metal engine shavings and pieces in my engine while draining my engine oil. Service team told me they contacted GM for a new engine replacement and my truck will be in their shop for a month waiting for delivery and working on my truck. All this damage because of the AFM DFM feature in V8 engines and it happening at 7,000 miles it’s unacceptable.

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.

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."

My 2022 Silverado is affected by a couple different electronic safety issues. The first one has to do with the trailering system. When I have trailer connected that has electronic brakes on it, the vehicle gives an error message and then shuts the break control off. When this happens the trailer does not assist the truck in breaking when the pedal is pressed. The truck has to do all the work to stop not only itself, but the weight of the trailer as well. I found this out while towing my camper that weighs approximately 7500lbs. This is very dangerous and unsafe. The GM dealership has verified this issue and gave me a bulletin that came from GM that states that they are aware of the issue and they do not no what is causing it or how to fix it. I also have issues with my smaller trailers that have no brakes. When connected, the vehicle will give me random error messages about the trailer lighting. When this happens the trailer lights flash without me pressing the brakes or using turnsignals. This also is a huge safety issue. People following me may not know if I am turning or stopping, which could lead to an accident. The dealership also confirmed this issue and they believe it may be tied to the other issue outlined in GMs bulletin. The bulletin doesn't say anything about trailer lights, so the dealership has no clue on what is causing it or how to fix it. The last issue is with the back up camera. It goes out periodically while backing up. This can lead to me hitting someone or something that I may not see in my mirrors. My vehicle is a truck and is pretty large. The backup camera is there to help in backing safety. The dealership did confirm this issue with a code in the computer, but they couldn't get it to replicate while it was in the shop so they are unable to get solution to fix it. I have to wait until it completely goes bad or GM releases a bulletin. I know I'm not the only one with this issue. It is documented on a few forums. I have a case with GM.
