8/31/10 Lexus 2008 Is 250 with 14K miles, trying to stop, brakes (ABS) pulsed very hard thump-thump-thump, dry pavement 30mph straight road. Next intersection applied brakes at 20mph steering pulled right then left as brakes were applied. Very scary-called dealer - got #roadside tow truck - in to service dept. Dealer ran computer diagnostics & test drove, no problems, did a nys safety inspection since it would expire soon. No problems detected, sent vehicle home. Driving home 10 miles from dealer - same pulling right/left when brakes applied. Not a gentle pull - like wheel being ripped out of your hands. No control at all. Returned car to dealer. Next day 9/1/10 three (3) mechanics test drove, only slightly feeling brake pull. Replaced brakes as a warranty, sent car home. Again, 20 miles out gently applied brakes while approaching rr track - car steered completely into left oncoming traffic - almost a head-on collision..turned around and took car back to dealer demanded a loaner vehicle till they fix. I am frightened for my life as well as others around me. This is a lease vehicle - which I still have for another 12 months. Is there any way I can cancel this lease? I'm afraid to take this car back again.

2008 Lexus Is 250. Car loses traction and control when braking over uneven surfaces. Have complained to Lexus since 1st week I owned the car, with no avail. Seems to be identical to problems reported for 2010 prius. Writing this to ask if complaints have been placed for this vehicle, or if it might be part of the investigation into the prius braking system?
