At 90,900 mileage on my van, I started experiencing problems with my stability control, ABS, and my traction control system. When driving at numerous speeds, the stability control system would kick in, would grab at my drivers side front wheel and make the van swerve to the left. On the instrument panel, it would say to "service stability control". this has happened when I was traveling at 40 mph, at 20 mph, and just starting to drive after taking a turn. This has also happened to me today to where I was pressing the brake and the traction control kicked in on dry pavement while I was going less than 30 mph. I have had my 4 children in the vehicle when this has occurred and has scared them as well as myself and my husband. This vehicle is our main form of transportation.

Every time the wheels are removed from my 2005 Buick Terraza, the rotors go out of round, and need to be replaced. I am wondering if any other owners have this complaint. We have had the rotors replaced three times in less than three years. They need to be replaced now. That makes it four times in less than three years. It is dangerous to have the rotors out of round. The mechanics believe it is because the tires are torqued too tight. Why does this keep happening? it is getting pretty expensive.
