Sierra

  • 50,000 miles
I am having serious problems with the stabilitrak electronic stability control system. Whenever it gets cold ( below approx. 38 degrees) the stabilitrak system malfunctions. Even if I turn it off it still affects the performance of the engine (low speed, engine hesitating). The truck runs fine in warmer weather just craps out when its cold. I see that there are many other instances of distressed drivers who are having their 'trac ' 'stab, ABS light and engine lights either going on one at a time or simultaneously because of this system. This is a stupid system that needs to be redesigned or eliminated all together. In any event I don't feel as though I should be the one to pay for the manufactures mistakes in design.

Sierra 8-cyl

  • 38,000 miles
About 2 months after we purchased our pre-owned 2009 GMC Sierra denali we started having problems with the engine power and all sensors going off. The sensors start going off the stability control cuts off it says engine power reduced then doesn't want to shift and kills in middle of traffic. It will do it for a few days and then just starts working right again. So we never know when it's going to happen or where we will be. It's like it's not running on all cylinders.
