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.

On 4/12/22, we were towing our 32ft trailer with putt 2011 diesel GMC Sierra truck to Big Bear Lake which is in the San Bernardino Mountains in a two way winding highway. Upon making a somewhat sharp turn up a steep uphill, our accelerator went out. We had my mother in law, our two kids and dog in the vehicle at the time. We were able to get a speed of about 5-10mph to get a turn out and turn back around. We had no reception to call for help. The accelerator gave out shortly after but we were able to ride the decline to the bottom of the mountain and as soon as we were getting to the bottom, the engine turned off on us. Although it was still a two way highway, thankfully there was an emergency lane where we were able to park and where we were able to get very limited reception to call AAA (tow truck). There were vehicle speeding past us in high rates of speed. Because we needed a specialty tow truck given the towing of the truck/trailer, we knew it would take quite a while in the mountains for a driver to get to us. Temperatures at night in this area can get to 10-20 degrees. Five hours later at 11pm we were towed home. Upon towing the truck and trailer home, we were made aware of the reason the truck broke down through a diesel mechanic, which was CP4 fuel pump failure. Upon learning this and going online, we found out this is common for this truck with the CP4 fuel pump. We also found that other companies have made recalls, eg. Dodge but GMC/Chevy has not. This is obviously a safety issue that could have been catastrophic for myself, my kids and family and am wondering why there hasn’t already been a recall through GMC. Please let me know what our recourse is or if you have any questions.
