NHTSA Complaint #10860202 — 2009 CADILLAC CTS

WHEN DRIVING ON THE HIGHWAY OVER NORMAL BUMPS (BRIDGE SEAMS, R.R TRACKS, HIGHWAY CONCRETE EXPANSION JOINTS) THE CAR PERFORMS AN UNCOMMANDED TURN TO THE RIGHT, THE STEERING WHEEL IS QUICKLY TURNED TO THE LEFT BY DRIVER, FOLLOWED BY THE STEERING WHEEL POINTING (UP TO) APPROX. 30-45 DEGREES TO THE LEFT WHILE THE VEHICLE GOES STRAIGHT. SOMETIMES "STABILITRAK OFF" MESSAGE SHOWS ON THE DASH THEN THE STABILITRAK LIGHT COMES ON, SOMETIMES NO DASH WARNINGS COME ON AT ALL. SOMETIMES THE AMOUNT OF STEERING WHEEL MISALIGNMENT IS A LITTLE, THEN A LITTLE MORE, AND CAN BE SMALLER AMOUNTS DEPENDING ON THE BUMPS. IF THE VEHICLE IS SHUTDOWN, THE DRIVER'S DOOR IS OPENED AND CLOSED, AND THE VEHICLE IS RESTARTED, EVERYTHING IS BACK TO NORMAL AND THE STEERING WHEEL IS STRAIGHT AGAIN. THIS IS NOT ONCE IN A WHILE, IT'S REPETITIVE AND HAPPENS DAILY. DEALER HAS ORDERED A STEERING WHEEL POSITION SENSOR TO FIX THIS AND STATES THAT WHAT IS HAPPENING IS IMPOSSIBLE.
