This is my 2nd Grand Prix. The other was a 1999 SE. No problems with it other than window motors going out. This car how ever...When turning at slow speeds or backing up the anti-lock brakes come on and the traction control lights come on. It is not saying that the traction control is off. It is affecting my braking and almost ran me into the bushes. I am worried this is going to cause an accident. With all the gripes they have to know that this is an issue! WTF? Why can't they step up and fix it? I have always loved Pontiac but this is BS! Now I have to take it in and of course it's $65.00 just to hook it up.Then I'm sure they are going to come up with all kinds of crap that they think I'm gonna tell them to go ahead and do. Not all women are idiot's when it comes to cars! Wake up GMC and make it right!

For over a year, about half the time I made a slow, sharp turn (i.e. parking the car), the ABS would activate. Seemed worse when on an incline, either up or down. There was no reason for the ABS to be needed, this was usually on dry pavement. The dealer originally said they had it narrowed down to either a wheel bearing or ABS sensor, but didn't have a trouble code so they didn't know which it was. Car was under extended warranty, which was coming to it's end, so they refused to do anything about it (and tried to charge my $80 for a diagnostic fee, even though they had no diagnosis...needless to say I refused). Called GM, talked to district/regional service managers to no avail.

Eventually I took it to a third dealer, who again claimed they couldn't find the problem but after getting the car back from their inspection, the problem had disappeared. Two independent shop mechanics told me that they knew of wheel bearings going bad in that year range (2001-2004 or 5) GM cars, which would rub on the ABS sensors and cause this problem...they said it was not an expensive part but extremely time consuming and annoying to repair. My mother had the exact same problem with a 2002 Impala, received similar treatment from the dealers and bought a Honda.
