When pulling my trailer with my 2024 chevy 3500, I get the following alert displayed on my screen periodically: Trailer Brakes Disabled Service Required. The trailer brakes stop working on my 16000lb trailer and I need to pull off the road and shut off the truck, and then restart it to get my brakes working again. The dealer replaced the brake controller in the truck, but I still get the message. I towed this trailer across country 2 times in my 2020 chevy without a problem. I have hydrastar brakes on my 2022 keystone Montana. GM said it's a problem with the trailer. Hydrastar said they have had numerous reports from 2024 GM truck owners. I am bringing it back to the GM dealer Monday for an oil change but I was informed they have no further information to guide them Please assist.

When driving my truck and towing a trailer which has elec. over hyd. brakes and trying to stop. My truck will disable my brakes on my trailer, which may weigh 3+ times the weight of my truck. GM had a recall on the truck brake module which fixed my problem. Then l took my truck back for an oil change a few months later and they said that there is a open recall on the brake module (NEWER UPDATE) which once again caused my brake issues again with the newer recall. l have opened up a complaint with GM and they say take it to a GM dealer. The dealer checks the truck out and says there is no problem with the truck. They tell me that l need to install a module on my trailer ,which l did early on with the problem. l did own a 2017 chevy and pulled that trailer with NO issues. The trailer dealer hooked the trailer to a 2018 GMC and a 2016 Dodge pick-up. And had NO problem with the trailer brakes and put a NYS inspection sticker on my trailer LAST MONTH. We !! the trailer dealer and myself have spoken to the company ( brake module) that GM says that l need. This trailer brake module which the trailer dealer installed in Feb 2024 still did not fix my problem. The brake module company told me GM has His words a HORNETS NEST problem with this issue. Someone is going to loose there brakes and KILL somebody or a family Thank You for any HELP [XXX] Please contact with any feedback or info INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The brakes on this vehicle are very spongy, they have to be pushed all the way to the floor to get the vehicle to stop. When pulling a trailer you are on pins and needles wondering if you can get the truck to stop. The trailer brakes are doing most of the stopping. I have owned many trucks and the brakes on this 2024 Chevy Silverado 3500 are the worst that I have ever experienced. This is a Safety hazard with serious implications. I have talked to many other people with the same truck and they also claim that the brake system is faulty and/or sub standard. I have taken my truck back to the dealer and they claim that the brakes are working normal (test driving around their service lot). This is a serious problem that needs to be investigated by your orginazation. Thank you in advance for any insight on this serious brake issue.

After replacement of the trailer brake controller for the well known issue of the new OEM trailer brake controller disconnecting from the trailer brakes, the issue still persists. The trailer brake controller should remain connected to the trailer brakes at all times instead of disconnecting under its own control and programming. It is a major safety issue to be trailering a 21,000lb trailer with 6 functional disk brakes and have the controller decide to disconnect at seemingly random times to include descending a mountain pass at highway speeds.

I was towing my 36 ft 5th wheel home from my storage place when the engine stopped. I had no brakes or power steering. I was coming up to a stop sign when this occurred so fortunately I was only moving about 15 mph. I was able to stop the truck and trailer by using the 5th wheel braking system without any damage to vehicle or other property. Once I regained my composure I tried to start the truck. All the dash lights were on but it would not start. The digital display kept showing Service ECM & Service StabiliTrak. I had the truck towed to the dealer where it is right now. They have been unable to replicate the issue and have no suggested fix at this time. I had no prior warning messages or symptoms of the problem. All of this happened Sunday April 5, 2024. The truck is a 2024 and I bought it new, picked it up November 30, 2023. Current mileage is 3,523. If I would have been towing on the Interstate at 60-65 mph around a curve this could have been catastrophic.

I have issues where I am connected to a new 42" 5th wheel and constantly get "Check Trailer Wiring" warnings as we drive down the road. I have been running with the lights on and they are on and fine, when the warning displays, but lose brakes to the trailer (both through pressing the brakes or controller and the trailer indicator light goes off). I cleaned the ground area and replaced the connector and still see issues. I checked continuity in the cable and good. I have been adding dielectric grease to the 7-pin connector. I saw a YouTube video where another gentleman, with a similar vehicle, had had the same issue and got a recall under GM Service Bulletin 6379278 for a trailer brake controller replacement. When I talked to GM/Chevy Consumer support, they advised that my truck was not under this bulletin and advised to call the NHTSA to get a case open or added to the service bulletin. I have a case open with GM #9-11303425686.

Recently purchased a 2024 Chevrolet Silverado Hd3500 and use it to haul a 40' 5th wheel toyhauler. Several instances when I connected the RV electrical cord to the truck I would see a "check trailer wiring" message. Along with this message I noticed there was no current going to the RV brakes. I had several technicians look into matter, but could not find a resolution. Later my brother sent me a YouTube related to this problem. It appears that if the RV has solar cells for power or the RV generator is running, the voltage on the RV battery is affecting the truck sensors and disables the brakes. This can be a life threatening issue for the vehicle driver or others on the highway.

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.

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.
