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.
