I bought a 2009 Chevy Impala with 35K miles on and not even a month after I bought it I started having problems with the traction control on acceleration and sometimes on braking... I see with all the internet complaints that this is a wide spread problem that GM seems to be putting off.. I have contacted GM and they told me the same thing as every other complaint take to dealer and spend over $100 just to get it looked at and the dealers say the same 3 things as all other complaints it could be three things.. gas pedal sensor, brake pedal sensor, or the sensor on the hub assembly... hmmmmmmmmmmm GM help... ps after I got mad on phone GM agreed to pay a mere $90 of the bill which is gonna cost over $300 to fix....
