Driving my truck, without a trailer, the "Service Trailer Brakes Soon" fault came on my truck. This is a known problem that GM is aware of with their ITBC system for YEARS & have done selective recalls for. This a hazard to the motoring public. There is no warning when this fault happens while pulling a trailer & when it does pop up, you lose all trailer brakes. I had the same problem with my 2010 Silverado, after numerous visits to the dealership & thousands of dollars & filed complaints with GM & NHTSA, nothing was done. When taken to the dealership, if the fault isn't on the screen, they claim they can't find or fix the problem. I pull a 10,000 pound 5th wheel, I need trailer brakes when I apply them.

Brakes are not efficient. They need enormous amount of pressure to stop. Or brake pedals must be applied(pumped) several times to stop better with less pressure.

Bought truck new. Bought a brand new fifth wheel trailer to tow. Sometimes while towing the trailer, the truck will "shudder" while driving at highway speed. This has happened maybe 3 or 4 times in the 2 years that I have had the truck and trailer. It "shudders" bad enough that it has nearly caused an accident. When it does this, the stabilitrak, traction control and all my gauges come on. The speedometer and tach reset. All this while driving. Brought to the dealership and all they do is point the finger at the trailer manufacturer. Trailer manufacturer says they are aware of the issue, and it is only happening to Chevy trucks this has been an issue since I bought the truck and trailer

Driving vehicle ABS and skid warning lights appears, brake system warning appears always lit while in towing mode. None stop beeping. No reason why this is happening. Had vehicle checked by multiple Chevrolet dealerships and they have changed sensors, towing plug twice, electrical rewiring. Began towing 1 hour after repairs and the same problems began all over again. No changes have been noticed $2700 later

The contact owns a 2016 Chevrolet Silverado 3500. While driving approximately 70 mph hauling a goose neck flatbed duel tandem trailer, the power bus bar shorted. In addition, there was a failure with a loose wire associated with the starter. The radio would not turn off and the contact was locked in the vehicle. The contact was able to exit the vehicle after several attempts. The vehicle was towed to the dealer. The dealer tightened the wires and replaced all of the bus bars. The next morning, within less than 20 miles, the bus bars failed again. The brake, traction control, and other warning indicators and gauges illuminated. The contact was locked in the vehicle and had to move the key back and forth as well as use the key fob to exit the vehicle because the lever would not release. The vehicle was towed to the dealer a second time. The dealer failed to route the wires correctly, in which the edge of the bracket rubbed a hole in the power cable. The tailgate fractured and shorted due to the failure, but the dealer and manufacturer refused to replace the part. The vehicle was taken to the dealer two additional times, but they were unable to replicate and diagnose the failures. When the contact took the vehicle to the dealer a fourth time, the dealer replaced the air intake heater. The manufacturer was notified of the failures. The VIN was not available. The approximate failure mileage was 4,000.
