GM is aware of a known failure in their Transmission Control Modules. My part number is 24256670. My truck has 87,000 miles on it and not drivable due to this failed electronic component. There are thousands of people just like me experiencing this issue. Check engine light illuminates once unit gets hot. Multiple codes will display at this time. This happened at a stop light, causing traffic jam and congestion, unnecessary safety infringement on all i affected.

Fuel pump fuse socket has melted in addition to fuse being blown. Fuel pump had been replaced twice with OEM fuel pump. Entire fuse box must be replaced. Occasionally, a no start condition can be traced to fuse contacts losing conductivity which can be resolved by removing them reinstalling fuse. Has potential of causing electrical fire

Randomly while driving, warning bells & lights flash, message in dic state service stabilitrak/traction control. Instrument cluster goes dead, A/C quits cooling & radio quits. If the vehicle is in motion it will continue to be drivable. As soon as you stop or are stopped when it occurs, the transmission stops working. The engine continues to run, and can be revved however the vehicle will not move. After turning off the ignition, opening the driver's door and waiting a couple of minutes, you can restart the engine, the gauges and transmission will once again operate. It has now started to periodically cause the driver side low beam headlight and driver's door lock to not function as well.

While driving in traffic the Silverado's, engine, power steer and power brakes shutdown completely. After the vehicle stopped. The automatic transmission was placed in park and the truck restarted normally. I took the truck to the dealer and they found no problem or code. The same event happened again about 3 months later while I was on an interstate driving about 70 mph. The I was able to bring the vehicle to a stop in the side of the road I then placed the transmission in park and the vehicle started normally. I believe there is an issue with the ignition switch.

Upon the start up, the instrument cluster will begin to shut gauges down, turn on all warning light, tach and speedometer go to 0. then the tach/speedo will come back with all gauges off and all warning lights on. Then the gauges come on and the warning light will turn off. This can continue up to 15-20 minutes while under way. It actually appears the truck has is not running while you are actually traveling at any speed. I have had the issue happen while sitting in the parking lot and moving over 60 mph. It is temperature related when it is cold out (40 degrees), the sequence happens every 20-30 seconds with the cluster not totally working for more than 15 seconds. This continues for over 5-10 minutes! this issue is spot on to an issue/recall of '03-08 GM trucks.

New vehicle front end suspension began to randomly violently shake at different speeds (once @ 55 mph & once @ 70 mph). The shaking was so bad that the driver could barley hold the wheel straight to avoid losing control & crashing. While this was happening the vehicle 4 wd light was blinking despite the fact that the vehicle was in 2 wd. Once driver was able to pull over he inspected the outside of the vehicle to find no mechanical issues (no flat tires, things in the wheels, etc...). driver then began driving again & the vehicle was fine as if nothing happened. Driver called onstar & they stated there were no fault codes in the system. Several days later the same thing happened while driving at 70 mph. This time the driver nearly got into a roll over accident. He was able to get the vehicle to the side of the road. Upon inspection there were again no mechanical issues. Owner drove to dealer & was told to bring back the next day. Owner inquired if vehicle was safe to drive & was told "I hope so" by the service technician. GM customer care was called & stated they were not aware of any issues with the 2011 hd vehicles. Owner took vehicle to dealer next morning & several hours later was called & told it was mud in wheels (not possible since the first time it happened there was no mud). Owners son then looked on internet to see many people having the same issue in this model year vehicle. The son then found that a tsb was issued by GM to all dealers for a sticky break pedal that when stuck (even though it appears visually to not be stuck) will at random times cause the ABS to activate violently. Tsb# pit5037B. Dealer was then told by owner about the tsb & dealer was not aware of tsb. Repair was performed & the vehicle has not shook since. Owner was suppose to be pulling a 30 ft 5th wheel with a 15 ft trailer attached to it (45 ft. Total). If they had been they likely would have been in major accident with possible loss of life due to the sway it causes when it occurs.
