While pulling my Vilano fifth wheel trailer to Alabama from my home state of Texas the driver information center alerted me that the trailer brakes were disconnected. Then a short while later it alerted that trailer brakes were connected. This situation continued for the entire trip to Alabama. When the info center indicated trailer brakes were disconnected, they were indeed not working. Several times I almost rear ended cars stopping in front of me. (The vehicle had a recall notice urging to take it in and replace the brake module shortly after purchasing it. I did this.) Once I arrived in Alabama I took the vehicle to the Chevrolet dealership in Foley, Alabama to check the braking system. They told me there was no problem with the braking system. I retrurned to my home in Little Elm, Texas with the problem occurring the entire trip. I finally made it home and today took the vehicle to James Wood Chevrolet in Denton, Texas to have the braking systme checked again. They told me there was nothing wrong with the braking system. The service writer did say that because the trailer has LED lights the braking system does not recognize the voltage from the trailer and that is why the brakes are disconnecting. Please help me find out how to correct this extremely dangerous condition while I am towing my 16,000 pound fifth wheel trailer.

Brake pad failure, at 22,000 miles brake pads are almost worn out and leave extreme amounts of brake dust on wheels. This issue has been happening since 500 miles. Was told by dealer that it's a cheaper pad that the manufacture uses and the wear is normal. Steering wheel shakes when brakes are applied and when you're pulling a load the vehicle starts vibrating and jumping. Now rotors are warped due to the faulty pads wearing out so soon. Dealer and GM refuses to fix it, dealer says it's not covered and not a safety issue and GM has no explanation for their rejection the claim.

When hooked to 5th wheel trailer the brakes work good for a day then info center says check trailer brakes. The trailer bakes are not operational at that time. A few minutes later trailer brakes are back working again.The truck keeps shutting off the trailer brakes and sometimes they do not come back on at all. It happens every time I hook up to 5th wheel trailer. I have had it back to dealership 6 times and they can’t fix it.

While towing our 25ft travel trailer, I began getting warning from the trailer brake controller which repeatedly disconnected and, thankfully reconnected them after a brief interval. Luckily, the times when I had no trailer brakes did not require rapid stops. That said, towing a 7000 # trailer thru the mountains in a driving rain storm with no brakes randomly caused a bit of concern. After researching this I find this is a known defect and has TSB’s and voluntary recalls in place. (TSB 23-NA-149 and N232414840 respectively) However I was never notified by GM as my VIN was not included in the above. We could have been seriously injured or worse. This tsb is almost 2 years old. Why were we not informed/included? Our issue is identical to the tsb.

SERVICE BRAKES

My trailer brake controller routinely does not allow me to adjust the brake gain. Multiple times (and on recorded video), I’ve had instances where I could not increase gain while hauling heavy loads in the trailer and this has caused me to lose my ability to stop the vehicle effectively. This has nearly cause accidents a few times while hauling on the interstate, and down my mountain road. The driver must be able to adjust trailer gain at any point while operating the vehicle. This issue has happened with multiple trailers. I’ve taken the vehicle in multiple times and had the brake controller components replaced but this issue still exists and the dealerships are unable to resolve. I was informed I have trailer issues even though this only occurs in this vehicle while towing and not other vehicles pulling the trailers. This is a major safety issue and will cause an accident if it isn’t resolved. My only option at this point is to purchase an aftermarket brake controller as my factory brake controller is unsafe. I have multiple videos of this issue and nearly had the trailer push me over my mountain from the issue. This issue has happened since I purchased the vehicle and continues to happen. There are multiple service records which show I requested the brake controller to be fixed. This isn’t a one time date or speed. I’m unable to upload videos I’ve taken on my phone but I can send them in. Reach out to [XXX] for videos. The manufacturer and service centers aren’t helping resolve this.

While driving with a trailer connected the display in the truck will say trailer disconnected. Then the light will go away and come back on. The trailer plug and the trailer are connected and the plug is tight. When this happens the trailer braking system is disabled (trailer has no brakes) I can plug the same trailer to Ford or Dodge with no issues. Have had the Chevy to the dealer 4 times now and they are unable to duplicate the problem. I have researched the problem on the internet and there are a lot of discussions of other people having the same issue. GMC has replaced the trailer control module, but this did not fix my problem. I am at the point the dealer and GMC are giving me the run around. I bought this truck for commercial use and frequently haul trailers. It is very unsafe when the brakes on the trailer are disabled.

I would like to report a hazardous issue with the 2024 Chevrolet Silverado trailer braking power mode. The trailer braking system turns on and off when the loaded trailer is connected; this represents a security hazard since this truck is used for work and we move heavy pieces of metal and glass. This issue was reported several times to the dealership Lou Bachrodt Chevrolet in Coconut Creek, FL. Also, the manufacturer provided a letter indicating the replacement of some parts. As indicated, I took the truck to Lou Bachrodt Chevrolet in Coconut Creek, FL, on [XXX] for the corresponding service; however, the truck is still presenting the same issues. We tried different trailers, including a U-Haul trailer, and still had the same dysfunctionality. Please advise how to proceed.

When pulling trailers I frequently get warning to check trailer wiring. I have gotten this warning with every trailer I have towed to include, my travel trailer(camper), livestock trailer, car hauler trailer and enclosed cargo trailer. It is intermittent but frequent. I am unsure if trailer brakes will engage during this failure.

SERVICE BRAKES

While towing our camper that has solar power our trailer brakes would randomly disconnect. Sometimes for a few seconds but several times for several minutes. After checking all wiring, doing some research and trial & error we discovered that it is a problem with the truck and the solar on the camper that is making the brakes disconnect. This happens randomly but quite often and it happened to us several times while towing in the mountains of Colorado. It is definitely a safety hazard to not have the trailer brakes. We have towed the same camper with other trucks including the 2023 Chevy that we owned before this truck and have never had a problem.

I have been going through a nightmare with my new 2024 Silverado 2500HD with the trailer brake that randomly connects and disconnects. My wife and I live Part-time in our 5th wheel RV and pull it on average once a week as we move from place to place for 6 mo out of the year. The issue is very random and we have had the truck at two different dealers to try and solve the problem. The Truck dealers point to the RV Mfg and the RV Mfg point to the truck Mfg. After doing quite a bit of searching, I found a GM tech bulletin GM 6379278 in regards to this issue so I now see on the internet and youtube many others are having the same issue. This appears to be quite the life threatening issue that can easily end badly. They talk about a solar pkg or generating package causing this problem, I have neither. The bulletin is applicable to 2024 3500's and 2500's

I kept getting “check trailer wiring” messages followed by a “trailer disconnected” message while towing a trailer and the trailer brakes would not engage. The trailer would “reconnect” and then “disconnect” constantly while driving. I lost my trailer brakes while trying to brake down a hill. Not having working trailer brakes is extremely dangerous.

If our trailer is plugged into the truck the warning "check trailer wiring" pops up. The warning ("check trailer wiring") would display and then the message "trailer connected" would generally happen. The trailer breaks disconnect during this time making it extremally dangerous for us and anyone else on the road if we need to stop quickly. This is not an issue with our new trailer as we pulled it with a 2017 Silverado with no issues.

New Silverado 2500 HD LT and new Keystone Cougar 30BHS. My new truck is experiencing random trailer break controller disconnection while towing. This happened yesterday on the first trip bringing it home from the RV Dealership to my house. The trip was 68 miles total. It happened often and without a pattern. It appears that many others are experiencing the same issue. See youtube link below: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

SERVICE BRAKES

This truck was optioned with the trailer tow package which includes a trailer brake controller. However, if the battery on the trailer is a higher voltage than the truck battery, the trailer brake controller will fail intermittently. This leaves the truck traveling at freeway speeds with no trailer brakes. This is EXTREMELY UNSAFE. GM is aware of the problem and has issued a technical bulleting "23-NA-113 Information on Trailer Brake Disabled or DTC Stored" on June 28, 2023. This is an EXTREMELY hazardous situation and should be resolved immediatlly or the truck owners should be advised to NOT TOW with the trucks until resolved.

SERVICE BRAKES

While pulling fifth wheel camper the the electronic brake controller looses connection and brakes on the trailer do not work leaving only the truck brakes to stop both truck and trailer. General Motors claims this is caused due to the solar panel on the trailer charging the trailer battery more than the truck battery which back feeds into the system. This problem only occurred on the 2024 models. The same trailer was pulled with a 2021 model with no issues. This is a known problem which Chevrolet has a service bulletin stating such. Reference document # 6379278. At this time there has not been a fix. This is a safety hazard because there is no warning as to when the trailer brakes will stop working.
