SERVICE BRAKES
While traveling with a 5th wheel camper, that has solar panels the brake controller stops providing a connection to the trailer brakes. This is a know problem of the 2024 Chevrolets and so far there is not a fix. This is a big big safety issue. The documentation from Chevrolet states the issue is once the battery charges and has a higher voltage than the truck battery it will surge the system and deactivate the braking system on the camper.

SERVICE BRAKES, UNKNOWN OR OTHER
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.

Truck will not stay connected to our trailer brakes. We have a 2023 Grand Design Reflexion 270BN. The truck stays connected about 30% of the time. 70% of the time we get the following warnings “Check trailer wiring” or “service trailer brakes” and the trailer brakes are disconnected. Grand design has said this is 100% on the truck side. GM needs to find an update for this dangerous problem. We almost got into two crashes on a 2000 mile trip. Multiple people are in the same situation as us.

We have a 2022 Grand Design Imagine 22MLE and when we tow it with the truck we are getting the intermittent message on the dash that the trailer brake wiring is not connected. It continually connects and disconnects as we tow and press the brakes on the truck. We previously towed the camper with a 2011 Silverado 1500 and did not have this happen. We took the truck back to the dealer for a service check and they had no answered for us. This is a serious safety concern while we are towing an extra 6,000 pounds behind us.

Pulling my 5th wheel camper and the trailer braking system goes in and out. It says, "check trailer brake wiring" and "service trailer brake". I have pulled same camper with a 2020 Chevrolet and didn't experience any issues. I have found some forums discussing that it's a GM problem with a service bulletin from GM #6379278 stating GM is working on the issue. This is a very concerning issue especially when towing over 10,000 lbs.

SERVICE BRAKES, ELECTRICAL SYSTEM
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.

When my fifth wheel trailer is attached via the seven pin plug, the truck intermittently fails to recognize the trailer and I get a warning "check trailer wiring." When I get that warning, the integrated trailer brake controller fails to activate the trailer brakes. After a while I get the message "trailer brakes connected" and then the trailer brake controller activates the trailer brakes. This problem does not occur when the trailer is attached to a different truck. Apparently this is a well-known problem that GM has failed to correct or inform customers about. Please see the comments at [XXX] . This is a serious safety hazard as my trailer brakes have failed to activate while descending some very steep grades in the mountains.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
The vehicle has, on numerous occasions, gone into a "Check Right Front Turn Lamp" or "Check Left Front Turn Lamp" while operating the turn signals. Vehicle then goes into "hyperflash" on the turn signal indicating a fault when the error message appears and renders the signal non-functional. Vehicle does not return to normal until it is shut off and restarted. Vehicle was taken to dealer for service on this item, the computer was re-flashed with latest software but problem persisted. Dealer indicated they believed there was no issue with the turn signal lights, it was a software issue in the truck. Servicing dealer is Jim Norton Chevrolet in Broken Arrow, Oklahoma. I have noted others in internet research with the same model of truck and similar LED lighting equipment experiencing the same fault.

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.

When towing my travel trailer with the 2500HD, the electronic trailer brake randomly connects and disconnects while driving. This results in the unsafe operation of the trailer because the brakes aren't functional and puts others at risk if stopping was required during the outage. GM/Chevy has created Document #6379278 which admits that this is their issue but they don't seem to be providing a fix.

SERVICE BRAKES, LANE DEPARTURE: BLIND SPOT DETECTION
The truck intermittently disconnects and reconnects from the trailer. Trailer brakes don't work briefly when this happens. At night when truck and trailer lights are on the truck detects trailer is disconnected, this happens every few minutes. Note: I've seen a bulletin about solar panels on the trailer, I do not have solar panels on the trailer. Also, blind spot mirror indicators at night are almost constantly on. When the trailer and truck lights go off, the blind spot indicators work as intended.

Brand new truck, 1st time towing through mountains of Kentucky, we kept getting "check trailer wiring", "trailer brakes disconnected" "service trailer brakes" I did research and took the truck in for service. They found nothing wrong, but said we should get an adapter and gave me the name of two. We had the camper checked as well, no issues. Many complaining on blogs about this issue and many have also been told to get an adapter. Really? why would I need a $200 adapter and the fact they already knew which two I should buy, tells me, they know its an issue with the vehicle. Pretty scary when we had to come to a stop on the freeway and we didn't have trailer brakes. Never had any issues pulling it with our 2021 silverado 1500. This is really dangerous

ELECTRICAL SYSTEM, SERVICE BRAKES
When truck is connected to a trailer with electric brakes, intermittently a check trailer wiring warning flashes on the dashboard screen. When this happens you do not have trailer brakes. It has happened on multiple trailers with 7 pin connections. I have taken it to the dealer twice with no fix other than GM recommending a non GM trailer receptacle. I have taken my trailer to the dealer and they could find no problems. Basically the 2024 Silverado 2500 HD when hooked to trailers with industry standard 7 pin 12 volt receptacle loses trailer brakes. This condition potentially is fatal and a definite hazard to public safety on roads. problem was reproduced at the Chevy dealership in Pensacola Fl. The problem was reproduced on multiple trailers at Great American RV in DeFuniak Springs Fl.

We have a 2022 Grand Design Imagine 2800BH for two years and towed it with a 2018 RAM 2500. Just recently purchased the 2024 Silverado 2500HD and our first tow the new truck kept disconnecting the trailer brakes then reconnecting. Apparently the new 2024 are having issues with their trailer brake modules recognizing trailers being attached. When you are towing a travel trailer and you need to brake and they’re not available because your tow vehicle is having issues recognizing a trailer brakes.

While towing my fifth wheel trailer, the electric trailer brakes module shuts off with a message "check trailer wiring". When the module shuts off, the trailer brakes do not actuate relying fully on the truck to stop as the trailer brakes will not work. The plug was firmly seated and it caused issues whether using the in bed plug or the bumper plug. After some time, the message would go away and the system would display the message "trailer connected" and the trailer brakes would work again. After some time, the process would repeat several times (30-40 times) primarily from mid morning to evening. I verified plug tightness and applied dielectric grease to ensure a good connection and that did not improve the issue. The trailer is 1 year old and was pulled with 3 other trucks (2 dodge and another Chevy) with no issues at all. I was able to locate a GM bulletin numbered "document id: 6379278" that references this problem and states to disconnect the trailer solar panels while a fix is developed. This was only found on an RV owners forum. I was able to disconnect my solar panels on my trailer and the issue was no longer present with my brakes working properly and no error messages for 10 hours of driving. This is a significant safety issue and needs to be made abundantly clear to drivers who haul trailers. Not all solar panels are easily disconnected and should be done by a qualified electrician due to the potential hazards of their voltage. Additionally, not having trailer brakes while driving on the interstate is a significant safety hazard that greatly increases the chances of an accident as the brakes would stop working without warning including while in use. My vehicle is a scheduled for an inspection at the dealer on 7/22/23.

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.

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.
