2024 Chevrolet Silverado 2500 Brakes

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.

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.

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.

I was towing a dump trailer with gravel in it down a gravel road grade (downhill around 5-7mph) and received a warning on the DTC about the trailer brake being disconnected. All of the lights on the trailer were still working, however the trailer brakes no longer functioned and all of the braking was transferred to the truck. The trailer slowly pushed the rear end of the truck around causing the vehicle to jackknife and causing significant damage to the bumper and bed. After researching this post incident, there appears to be numerous complaints and TSB from chevy regarding a faulty brake controller when towing a trailer where the voltage can backfeed into the vehicle causing the vehicle brake controller to disable. Currently working with insurance to come up with a damage quote. Bulletin # 23-NA-149

When pulling trailer trailer brakes keep disconnecting

The contact owns a 2024 Chevrolet Silverado 2500. The contact stated while driving at an undisclosed speed, the brake pedal was depressed; however, the brake failed to function as intended. The contact stated that the failure occurred while a trailer was connected to the truck. The vehicle was taken to the dealer; however, the contact was informed that there was no resolution. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 15.

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

Connecting this trailer to a new 2024 Chevrolet Silverado 2500 HD, the trailer brakes cut in and out every minute or so. The truck shows a warning that the trailer brakes are disconnected, and then they reconnected. This happens repeatedly. General Motors and Forest River have been advised of this, but neither have a solution. Forest River does not want to engage with me (as consumer). GM is still working with me to trouble shoot. Theory is that the solar charging on the trailer is causing the issue with the GM vehicle. Truck (not the trailer) was in the dealer and no issues were found on the truck side. In social media groups, there are many others experiencing the same issue.

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)

The trailer brake controller on the vehicle is defective and keeps connecting and disconnecting. It's a known issue to the manufacturer as shown in service bulletin #6379278 image attached. The manufacturers solution is to contact the trailer manufacturer for instructions on how to disable the solar charge controller. I have done this but the trailer manufacturer (Grand Design) will not provide me with this information as they are saying this is a Chevrolet issue and Chevrolet needs to resolve it. This now places me in a situation where I am traveling with a trailer that randomly, and intermittently, has no operating brake system. This places me and the driving public in danger. This problem has been inspected by the manufacturers dealer and they have provided me the technical bulletin referenced above. There is a warning lamp on the dash that informs me of when the trailer brake controller connects and disconnects. This failure first appeared to us on May 30th, 2023 which was the first time we connected to our Grand Design 2500RL trailer. It has been consistently having this issue every time we are connected to the trailer. The truck has been to two Chevrolet dealers so far to try and resolve this issue. I have contacted Chevrolet customer service for an ETA on when this issue is to be resolved and they have none.

When I hook up my 35' fifth wheel camper to the truck the brake controller from the truck to the camper acknowledges the connection then when I start to drive my truck dash states, "check trailer wiring". This is an extremely dangerous condition. At times I will get a message that states that the trailer wiring is connected then the brakes will work for a short time. I just saw a document ID no 6379278 that was posted on line that states what i said above. It has been back to the dealer a couple of times for this.

Component - Integrated Trailer Brake Controller Safety - caused a vehicle skid and loss of control Inspection - it is scheduled to go in to the dealer today Warnings - the dash messages "Trailer Brakes Connected" and "Trailers Brakes Disconnected" displays often when a trailer is connected, as frequently as several times per minute. I believe that NHTSA and GM are aware of issues with the trailer brake connector on these vehicles. The integrated trailer brake controller connects and disconnects the trailer brakes as often as several times per minute. I have confirmed there is no issue with the trailer. The issue appears to be in the truck. This led to a near-miss accident. I was towing a double axle trailer with electric brakes on I-77 in West Virginia. The trailer brake controller disconnected and reconnected throughout the drive with warning messages displaying on the dash. I applied the truck brakes to stop for traffic on a downhill slope in the rain. As I applied the truck brakes the trailer brake controller re-connected and applied the trailer brakes at the relatively heavy force that I was using for the truck brakes because the trailer brakes had disconnected. This caused the combination truck and trailer to jolt and then skid on the wet pavement. The truck is scheduled to be serviced at a GM dealer today.
