The contact owns a 2014 GMC Sierra 1500. The contact stated that while driving approximately 45 MPH, the vehicle drove over a slight bump in the road. The contact stated that the vehicle bounced, and then there was an abnormal banging sound coming from the rear of the vehicle. The contact recently had work completed on the exhaust system. The contact took the vehicle back to the independent mechanic who had performed the exhaust repair. The mechanic raised the vehicle on the lift and became aware that the rear passenger's and driver's side cross members, supports for the shock absorbers, and the rear sub frame had extensive corrosion. The contact was advised by the mechanic that the banging sound was coming from the shock absorbers striking the bed of the truck while driving over the bump in the roadway. The vehicle was not repaired. The manufacturer was not informed of the failure. …
Cross frame member ahead of rear wheels has rotted and failed. It is located behind the cab and is the cross frame that holds up gas tank and forms the anchor point for the rear shock absorbers. I have been told by dealer that truck is not safe to drive. It is now at a body shop. The suspension is compromised, gas tank could fall, and drivability safety is affected. Truck is only 8 years old, the cross member is not visible to consumer, there has been no undue use or environmental conditions to cause the rot and failure of the component. Further, the manufacturer does not sell a replacement part, so the entire frame of the truck would need to be replaced.
Within the first week of buying my 2014 GMC 1500 SIERRA, the transmission fluid was black in griddy. I have had it flushed, then filter changed and new fluid put in within 2 week time frame. A week later had to put a new transmission in it. It barely would drive. So a purchase at 2,999 then to a transmission 4,800 and new control arm with ball joint with new axels. They were busted. Another 2,000. Its sicking. Advice
I have a 2014 Silverado high-country. The truck has approximately 110k miles. I was told by chevy the frame is rusted through and unsafe to work on. They know these trucks had problems with the rust coating and only put out a bulletin to have them recoated. The problem is rust is rust. Once the metal was exposed there is no going back. My truck would other wise last another 50-70k miles.
Electrical glitches happen at both, low speeds and while on the roadway. My steering wheel tightens up and I get a message on the dashboard "Stabilitrak" and another one "assisted steering reduced, drive with care". My vehicle even shut off on me after pulling in to a parking space after turning steering wheel completely to one side

Truck vibrated new with 8 miles when we first drove it home. Pinpointed specific speeds and returned 9+ times to dealership over 7 months. Tires (twice), shocks and rear end were all replaced but did not stop vibration. 5 months from purchase we were followed by a neighbor and they saw my truck "dog tracking" (traveling sideways down the road). Dealer noted but would not follow at distance and speed required to witness the "dog tracking". Dealer told me they were clueless and come get the truck. Local auto repair shop followed me and said there is definitely a problem. Front center of wheel to back center of wheel measures 1/2 inch less on driver side than passenger side but dealer says that is not a good measurement because their computer says everything is fine. This truck vibrates and "dog tracks" and dealership refuses to make proper offer and has given up on repair attempts. …
