I have always been a GM fan, but this is beyond frustrating and beyond reasonable! With the sheer number of others with the same problems, GM should be recalling and fixing these hazardous concerns. My impala will display the traction control dummy light ( on warm dry days, even before I put the vehicle in GEAR!), and the "reduce the power" at random as well. I mean seriously, I can't leave a parking lot because I can't accelerate enough to stay ahead of oncoming traffic. With the reduced power kicking out at random, I am an accident waiting to happen. This makes driving a hazard and on occasion when the traction control is also lit (they most often coincide) the car can steer "differently." After multiple attempts at repair I have parked the car and gone back to my dying 2004 because it is safer and more reliable for my family. I can't ethically sell it & who know when it will act up, although it has increased to most days, most of the time. COME ON GM step up and do what is right!!!! Ford did something similar with a costly impact on our family, in the 80's and no one in my (even extended) family has purchased a ford since.
