On or about [XXX], the Transmission Control Module, FAILED, on my 2011GMC Denali 2500 6.6 diesel. It was a KNOWN faulty part .General Motors was aware of the issue years ago. This part should have been deemed a Safety Recall item. Imagine, pulling a trailer down a busy Freeway, with Semi's presence. Module goes out, truck goes idle, people hurt or worse. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When vehicle is warm and shut off, upon restart it will not go in to any gear, there was no warning lamps. An independent repair facility determined the Transmission Control Module was defective. General Motors has no parts available, and I know fro a fact it is a rather large issue.

TCM failed. Couldn’t find the parts required. Truck sat 700 miles away from me for four weeks. Had to have part repaired in hopes it worked. As of now I still have some issues but would not have the truck at all if I had to wait for a part

my 2011 fmc sierra 3500 drw denali suffered a failure of the Transmission Control Module (TCM). I could barely move the vehicle and almost got into an accident merging into traffic. Forward and reverse was affected. The transmission reverts to top gear after the failure, and makes driving very difficult. There was no warning for this failure Luckily I was minutes from my dealership. This problem could be bad.

I own a 2011 GMC Sierra 1/2 ton pickup truck. It currently has 98 k miles. The crossmember for the frame rusted out and fell off last month. Yesterday the frame broke in two. I see from looking online that GMC failed to add rust inhibitor to the steel for the frame. This is a safety issue and could have been catastrophic. Is anything being done about this failure? Online forums show this happening throughout the US.

Hit a pot hole in a parking lot and the gas tank fell onto the ground. Upon further inspection, it was discovered that the frame cross members and fuel tank straps are rusted/rotted and cannot support the tank.

The main body frame is completely rusting through from under the drivers side door back past the fuel tank. It is rusting through on the passenger side as well. The large amounts of rust have caused other issues throughout the entire body of the truck as well as rusting of other components. The frame of this truck will need to be replaced as there is no way to repair it or the vehicle becomes scrap. This vehicle is available for inspection. These issues were not visible when purchased from the dealer. This issue gradually became visible after the rust and undercoating wore away that had been applied previous to our purchase from a known dealership.

Just noticed that the Frame is rusting badly. It is available for inspection upon request. I see that the Chevy Silverado has the same problem and that a recall exists for it, but not for the GMC Sierra, which is virtually the same truck. My safety or the safety of others can be put at risk if the frame were to fail. The problem has not been reproduced or confirmed by a dealer or independent service center. The vehicle or component has not been inspected by the manufacturer, police, insurance representatives or others. Unknown about any warning lamps, messages or other symptoms of the problem. No failure yet.

I have a 2011 GMC Sierra Standard Cab pickup truck. I’m a disabled veteran and have this as my primary vehicle. The frame has a huge hole that developed and will need repair. The frame is rotted and soon will not pass inspection. The truck looks brand new but Engin compartment, frame and tow parts have rotted. I had the leaf spring separated from rotted frame on the highway. I swerved and almost died. GMC must replace the frame to make this right. Soon I will have no truck after giving GMC so much money. It’s criminal what they have done.

11/2022 shift cable separated from shift lever; preventing ability to put vehicle Into park. Retaining clip deteriorated allowing separation. Fortunately it happened when leaving parking garage and not moving fast. Was able to refasten using zip-tie until new retaining clip arrived at auto parts store.
