Right after I bought my vehicle the brakes started jerking/grinding when I go around a particular curve. The dealership says they don't find anything wrong w/ it. I have had it to them twice b/c of this and they even hooked it up on a computer and said nothing was wrong. I can't get it to reproduce it while they are in the car w/ me and they can't reproduce it when they drive it. It usually happens everyday when I go around this one particular curve. It's like it stops and I can feel the brake pedal jerk and it makes a jerking and grinding sound and sometimes it makes a steady beeping sound (like when your trying to tune in a radio station or something). Still hasn't been fixed as of today.
