One problem related to brake abs warning light has been reported for the 2001 Ford F-250. The most recently reported issues are listed below.
While driving back home from shopping my brakes (anti-lock style) locked up and violently shook my vehicle all over the road I was driving on. I had limited or no control at all of this incident. Was doing about 40 mph. Truck acted as if brakes were applied on and off 50/60 times so fast that there was nothing to do but hang on to the steering wheel. At one point I thought I was going to flip over as the truck went sideways. Steering went from side to side at first, then a constant pull to the right. I thought one of my front tires was blown out. Slowed down enough to gain some control but it took my truck over a curb and stopped on a sidewalk and some grass. When I did apply the brakes nothing happened until I was on the sidewalk and going very slow by this time. Got out and inspected my truck for damage but saw nothing. Was only about . 3 miles from home so I started my vehicle and limed it home at walking speed. When I tried to go a little faster it would start jumping and shaking again. Got it home and that is when I noticed the abs light was on. It was not on when I started home from the store. This happened so fast that I am glad no one was in another lane. This happened on a 3 lane each direction road. All this occurred on July 4th at about 10:47 a. M.
