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.

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
