ELECTRICAL SYSTEM, POWER TRAIN, VEHICLE SPEED CONTROL
Failed TRANSMISSION CONTROL MODULE (24256861). While driving in the early morning hours (darkness) taking my child to school, I was navigating through a busy intersection when the vehicle surged and then made a loud metal on metal sound, feeling as if someone had struck me from behind. At that point the power train became inoperable, stranding us and coming very close to being first, struck from behind and then from cross traffic. The vehicle was/has been inspected by a GM technician at Starling Chevrolet, St Cloud, FL and the TCM was found to have failed (trouble code U0101, lost communication with TCM). It has been at the dealership for going on four months awaiting the production of a replacement part(TCM). There was no prior indication that the TCM was about to fail. Upon failure, all lights on the vehicle display flashed and the indicator for the vehicle drive position was lost (P, R, N, D), no longer visible.

STRUCTURE:BODY
I took My 2012 GMC Sierra with 112,410 miles in for annual safety inspection and was told that my frame has a hole in it and is cracked, hence un-inspectable in the state of Vermont. I then took it to a welding shop to get an estimate on repair and the tech told me he sees this all the time on this era GM/Chevy trucks. This is clearly a widespread incident and GM should be held accountable like Toyota was years ago with its bad frames.O

STRUCTURE:BODY
Vehicle has just over 113,000 miles and the frame is already severely compromised due to rust. Nearly all factory coating is gone. I believe the sub par wax like coating that GM used from the factory was never intended to last anywhere near or over 100,000 miles. I have personally inspected numerous 2007-2013 GMT900 trucks in or around ohio and have found similar severe rust issues. All vehicles inspected were between 60,000 and 120,000 miles. The rust issues are the worst in the areas directly in front of the rear axle where the frame drops. Nearly every vehicle inspected has structure compromising rust in this area. GMT900 platform vehicles with rust issues in this area are unsafe to be on the road, yet they remain popular in multiple service industries and are frequently seen pulling trailers. GM has done a great disservice to their customers by using a sub par coating on the most important structural component in a vehicle. These trucks should easily last well over 250,000 miles but due to poor coatings they have a hard time breaking 100,000 miles.

Dash is totally falling apart. There is large cracking above the gauge cluster and around the passenger airbag, and every day I am removing more small pieces that fall off. These pieces are small, sharp, hard plastic and even metal in some places that will cause serious damage to any occupants if I were to get in an accident. I treat my vehicle very well and have done my best to keep cracking under control but it is getting worse and worse every day now.
