I OWN A 2009 LEXUS RX 350. WHEN I AM DRIVING ON A BUMPY ROAD AND APPLY THE BRAKES THE CAR WILL NOT STOP. THEY ACT LIKE YOU ARE GOING INTO A SKID. SHORTLY AFTER PURCHASING THE CAR I REPORTED THE PROBLEM TO LEXUS. THEY KEEP ASSURING ME THAT THERE IS NOTHING WRONG WITH THE VEHICLE. I HAVE BEEN LUCKY ENOUGH TO AVOID SEVERAL NEAR SERIOUS ACCIDENTS . I HAVE HAD TO JUMP CURBS ON SEVERAL OCCASIONS. I HAVE ROLLED INTO THE MIDDLE OF INTERSECTIONS WITH CARS COMING AT ME IN ALL DIRECTIONS*TR
