I was driving on Interstate 15 northbound on March 6th, 2023. I was driving 70 mph, my truck dash had a message come on that said Stabilitrak needs service. Once this came on the truck dropped down to 45 mph during rush hour traffic. My truck is currently at Young Chevrolet in Layton, Utah because this happened again last week on Monday April 3rd, 2023. The Stabilitrak message came on and then my PRNDML indicator disappeared. I could not get the truck to go into any gear besides neutral and drive. I had to shut the truck off, wait then restart it. This happened when I was trying to back the truck up into my driveway and I was almost hit by another vehicle. The technician at Young chevrolet said my TRANSMISSION CONTROL MODULE WAS BAD, from my own research of online forums and social media pages, there are numerous others with the same exact problem. …
Steering great box replaced steering still not stable, electrical glitches such as stability trac service message, hill assist, breaking assist messages pop up and then disappear constantly, power steering pump, hydro boost and master cylinder replaced multiple times, no sound emitting for seat belt, door chime , turn signals with no accessory mode power when key is turned.

My pickup truck has a Duramax diesel engine with a CP4 diesel injection pump. That pump has not failed yet in my truck. However it has been known to fail in numerous other GM vehicles with Duramax engines and when it does fail the engine comes to a complete stop and cannot be restarted. This is a potentially hazardous even fatal situation. Repair if the pump fails is very expensive - $12,000 to $14,000 in some cases. I would like GM to replace the injection pump at my dealership to ensure this known failure does not occur. My pickup truck is otherwise in excellent condition.
I was pulling a camper in in downtown Dallas Tx and the TCM failed was most ran I'm not sure how times trying to get clear of traffic to safe place on the side of the road.Dealership told me I was just she it out of luck cause there not making the part any more and that's when I found out GM has known about this for a long time and has done nothing to fix it.
Driving 70 on interstate 15 and the stabilitrak message came on the dash, truck went into limp mode, the truck went from 70 mph to 45 mph really fast. This was during rush hour traffic and I could have gotten in a wreck. This is a transmission control module and GM and Chevrolet DO NOT HAVE THE REPLACEMENT PART. It's on a nationwide back order
Fuel pump cracked under normal wear and tear under 60,000 miles leaving me stranded for a week and costing $1600 to replace. Transmission is very unresponsive and soupy, sometimes it kicks in late, other times not at all. Ive read this is a known issue with my vehicle.
While driving on cruise control around 70 MPH my check engine light came on. About 20 seconds later an alarm sounded and a message in my dash saying transmission fluid hot and to idle engine immediately. I immediately pulled over and called the dealership where I purchased it and had all services. Although the service representative I spoke with said it probably was just a sensor, I elected to have the vehicle towed to the dealership for repairs. The next day the same service representative advised me that my torque converter went out causing my front pump and transmission module to go out and I needed a new transmission assembly. My vehicle has 43,000 miles and I rarely tow a 3,000 lb boat. I was then told my 5 year 60,000 mile warranty expired 26 days prior to this issue. After researching, I found that this appears to be a problem with the 1500s. …
