Consumer Description

The car needs an PCM upgrade because it’s lit up a code in randomly situation. Causing the vehicle to lose the water temperature gage, power steering wheel assistance reduced and ac stop working, gmc is aware of the problem even issued a technical bulletin in 2018, but instead of inform the clients about the defective part, they want the client with this problem to pay to upgrade a defective PCM that came out from factory with problem. Note the power steering wheel assistance is part of the safety of the car. The problem always existed in the car, it toke me 2 years to find the problem.
