Wiring problems of the 2011 Chevrolet Silverado 1500

1 owner. Never driven on salted roads(south louisiana). Live 100 miles from coastline,not in a saltwater environment. Or driven in water other than rain. Cruise control dropping out, automatic transmission not shifting when supposed to. Traction control dropping out, service messages cycling in and out--traction control, stabilitrac , anti-lock brakes, check engine light, red brake light comes on and off. Speedometer going crazy. Brought vehicle to gm dealer for inspection/repair. Cause- internal failure of ecbm-electronic brake control module, due to corrosion in the connector due to water intrusion. Had to replace the module, and the vehicle chassis wiring harness. Total repair was $1,830. 39 for parts and labor. The dealer reported to me that the design/installation location of this module is flawed, and a faulty design allowed moisture to get into the module thru the connector. Which also resulted in the wiring harness connections into the ecbm also becoming corroded. . Dealer also told me that this faulty design will eventually become a recall, and for me to keep my invoice of this repair, as to be able to claim a reimbursement for this repair.

The driver's side headlamp wiring is faulty. I have continually replaced headlamps, only to have them need replacing in a month or two.

Stability control alarm blinking ,traction control alarm blinking,, speedometer going erratic, brake lite staying in alarm,cruise control dropping out,power loss temporarily. Shifting between gears (auto xmission) was very rough. This was an electrical system that grew steadily worse. Gm dealership had to replace the ebcm, and the chassis wiringharness. Severe corrosion. Vehicle never driven in salted roads,never flooded,never driven thru water. The location of the ebcm is poorly designed. Dealership said they have never seen a module this corroded,as it was in pieces when they pulled and opened it. I waited 4 months to get it fixed, as a early mechanic saw an electrical fault, but couldn't pinpoint it as it wasn't staying in fault. He said it needed to get worse before it could be properly diagnosed. Had to bring to dealer for repair as it got progressively worse. Cost me $1878. 36 to get repaired.
