Automatic Transmission Control Module problems of the 2014 Chevrolet Silverado 1500

The 2014 and up Chevrolet Silverado 1500 models are notorious for electrical issues and bugs, some may have been recalled but other were not included in that recall while still having the same issues, these vehicles have major electrical system issues, from bad battery cables, down to every control module associated with the truck, over time salt, sand, mud, moisture disrupts certain key areas of the electrical wiring harness underneath the vehicle, general motors knows about this but fails to recall these vehicles, it creates a very serious matter when you have no traction control, or any abs function, along with loss of power steering assist. These control systems can be life and death when they are not working!. Gm needs to address these issues and recall all 2014+ silverado’s and alike for these electrical issues relating to “loss of communication with the ecm, bcm, tcm, ebcm, tccm, pscm, etc. These are costly break downs and these modules are very expensive to just throw in and hope it fixes the issue, most dealers don’t want to trace wiring issues and will just tell the customer cannot replicate which leaves us vulnerable. Some customers state their vehicles will randomly shut off while driving, others report their truck going into “limp home mode”. Nobody can seem to centralize a specific area where the problems are occurring but believe it has something to do with the material and the way the harness was made.

Tl the contact owns a 2014 Chevrolet Silverado 1500. The contact stated that the vehicle seized in 4-wheel high. On several occasions, the service 4x4 or service stabilitrac warning indicators illuminated. The vehicle was taken to bidelman Chevrolet Buick GMC (located at 4048 oak orchard rd, albion, NY 14411, (585) 331-8162) where it was diagnosed that the tcm module needed to have a software update performed. The contact was informed not to shut off the vehicle in the 4-wheel drive position. The vehicle was not repaired. The manufacturer was contacted. The approximate failure mileage was 30,000.

Driving through the parking lot when I noticed a loss of power. I looked down at the dashboard and saw the check engine light was on. After calling the dealer, I attempted to drive back home. The truck wouldn't go past second gear. I even tried putting it on manual and shifting myself. Even though the lever was on m, the m itself did not light up and the + - buttons did not work. Thankfully I made it home with the hazards on. This is the second time dealing with this issue. The dealer said it was the transmission control module the first time. Now they are saying it's the speed sensors.
