2024 Chevrolet Silverado 3500

The contact owns a 2024 Chevrolet Silverado 3500. The contact stated while driving at an undisclosed speed and towing a camper, upon coming to a complete stop, the message "Brakes Disconnected" was displayed. The vehicle returned to normal functionality, but the failure became a regular occurrence. No other warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure a failure with the brake control module. The vehicle was repaired, but the failure reoccurred. The vehicle was taken back to the dealer, who again diagnosed a failure a failure with the brake control module. The vehicle was repaired, but the failure reoccurred. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 200.

While traveling with a 5th wheel camper (Grand Design), 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 that I know of. This is a big big safety issue because the trailer is heavy and hard to stop. 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. This also hold true when the camper battery is too low, again the truck battery will surge the system and deactivate the braking system on the camper.

The contact owns a 2024 Chevrolet Silverado 3500. The contact stated while driving at an undisclosed speed and towing a trailer, the trailer brake light turned off, indicating that the trailer brakes were no longer functioning. The vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the brake control module. The vehicle was repaired, but the failure reoccurred. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 500. The VIN was not available.

Occasionally, after starting engine and applying brake pedal to shift into drive from park, engine rpm increases to over 1500rpm, and with full brake pedal applied rear wheels will spin while front brakes remain engaged and front wheels remain stationary. This has happened in a parked garage and rear wheels spun on dry concrete. Adding additional brake pedal pressure did not stop rear wheels from turning. This could result in a very dangerous situation and cause the vehicle to surge forward with little warning to driver allowing the vehicle to strike an object or bystander. When this occurred, brake pedal was firmly pressed and foot was completely off of the accelerator pedal. Each time this occurred I had to quickly shift vehicle into park to correct the situation. When shifted into park, the transmission parking pawl could be heard ratcheting. It is my belief that if four wheel drive was engaged, vehicle would move and overpower brakes when this occurs.

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.

There is an electrical / turn signal and trailering issue. Not towing- the right turn signal gives a rapid flash when the automatic headlights are activated or in off position. The rapid flash goes away when manual headlights are used both running lights and on. Although the light still works with a rapid blink, there is a dash error message and it’s impossible to know while driving if the error is real or not. This issue is intermittent when auto headlights are selected. Towing- bigger safety issue. The trailer lights only work properly when headlights are in auto mode and daylight. When it gets dark, the headlights turn on and error messages happen and trailer lights go out. There are also error messages when manual running lights or manual lights are activated. Thus it appears there is no way to tow an RV safely at night. This did not occur on my 2021 Chevy 3500. These issues are wide spread but GM is doing nothing about it. Please help me, the other owners, and the public from these dangerous vehicles.

The vehicle was involved in a single vehicle roll over crash. The sheet metal of the roof pealed down and away from the frame of the vehicle. The windshield separated from the metal at the top portion of the windshield. The metal then began to separate from underneath the weld along the sides of the roof. The metal was then rolled inward into the passenger compartment of the vehicle. The metal pinned the front passenger seat back down and to the right against the passenger side B-pillar. Both A-pillars did not sustain any structural damage as the result of the crash.
