Consumer Description

While connected to a RV which has onboard batteries, the truck's brake controller disables the braking system if the batteries on the RV fluctuate in voltage. The truck will give an alert advising "Trailer Brakes Disabled." This has occurred multiple times while pulling my RV which weighs 16,000 pounds, making it unsafe and hard to stop using only the truck's brakes. It happened while traveling through Atlanta, GA and once in Nashville, TN. Chevrolet has at least one TSB on this for similar 2022-2024 2500 and 3500 trucks. This has been a widely reported problem on several RV forums. The truck brake controller will work again if the engine is shut off and turned back on or the trailer is unplugged and re-plugged in the truck. This problem occurred approximately 10 times on my trip from Missouri to Florida in January and about the same number of times when returning to Missouri at the end of February.
