2012 Silverado 3500hd with dealer installed dejana rugby dump body the dump body hoist makes contact with the electronic trailer brake/body control module eventually cracking open or damaging the top of the module and allowing moisture/water inside damaging the module. This causes a no start condition and or erratic gauges, door locks, ABS & brake lights to come on, drivability issues truck can go into a limp mode with no shifting etc. Test equipment shows no communication to ECM errors and drivetrain- problem will occur while driving. When the trailer brake control module is unplugged all symptoms will go away and truck will function normal. This problem started with a service trailer brake warning from the vehicle information center in the dash.

Here is a brief history of the issues involving the 1012 Chevrolet Silverado lt Texas edition after the purchase date of September 3, 2012. First, I noticed that it has increasingly become more difficult to open the front passenger window from the driver side master control unit around 2014. Now, I have to press hard several times to open the window. Second, the outside moldings of the door panels are falling off starting in mid-2014. Third, I have started to hear popping noises coming from the ball joints when the steering wheel is turned to the left or right at a very low speed starting the beginning of 2014. These issues were reported to the Chevrolet customer service at the GM headquarters in August 2015. On September 4, 2015, the truck was finally diagnosed by the Chevrolet dealership service department that sold the pickup. The invoice dated September 4, 2015 indicates the lower ball joints worn with play, door moldings falling off, and the driver's master switch shorted.

There is a very high pitch noise the is emitted from behind the dash. This noise is distracting to the point that my wife can not ride in the truck let alone drive it. I have taken the truck to the dealer and was told by the service department that General Motors is aware of this noise and it is acceptable.
