Frequently, braking will actually cause an acceleration. If I'm going down a hill and am pressing slowly on the brake to slow down, and then hit a bump in the road, the car accelerates and there's a bump, bump, bump until finally the brakes engage. I have taken it in for service and was told this is just the way abs works. However, I have driven other cars with abs (including Hondas) and have never had this problem. This has happened over 30 times since I bought the car several months ago. One time I nearly collided with the car in front of me.
