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.

My steering wheel tightens up and I get a message on the dashboard “Stabilitrak” and another one “assisted steering reduced, drive with care”.

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.
