MY BMW Z4, VINXXXXXXXXX, INTERMITTENTLY HAS A NOTCHY FEELING IN THE STEERING AS IF THERE IS A RESTRICTION PREVENTING THE STEERING WHEEL TO BE MOVED TO THE DIRECTION I WANT TO GO. THIS HAS BEEN GOING FOR A HALF A YEAR. NOW I AM INTERMITTENTLY LOOSING THE POWER ASSIST STEERING WITHOUT ANY WARNING. THIS IS VERY UNNERVING WHEN TRAVELING IN HEAVE CITY TRAFFIC. THE BWM DEALER IS NOT TAKING THIS AS A VERY SERIOUS SAFETY PROBLEM. THUS FAR NO REPAIRS HAVE BEEN SUGGESTED OR PERFORMED. *TR

WHILE DRIVING ON THE FREEWAY THROUGH A CURVE, THE STEERING WAS HARD TO TURN, WOULDN'T RETURN BACK TO CENTER AND HAD TO MAKE NUMEROUS ADJUSTMENT TO KEEP THE CAR WITHIN THE LANE. IT WAS VERY UNSETTLING AND COULD EASILY HAVE CAUSED AN ACCIDENT. THIS HAS HAPPENED SEVERAL TIME IN THE PAST AND IT SEEMS TO HAPPEN PREDOMINATELY ON WARM DAYS. *TR
STEERING GETS HEAVY AND "STICKY" AT HIGH SPEEDS. *TR

TL* THE CONTACT OWNS A 2003 BMW Z4. WHILE TRAVELING 10 MPH THE CONTACT NOTICED THAT THE STEERING WHEEL WILL SUDDENLY LOCK AND THAT THE POWER STEERING WARNING LIGHT WOULD APPEAR ON THE DASHBOARD . THE VEHICLE HAD NOT BEEN DIAGNOSED. THE CONTACT NOTICED PRIOR THAT THE FAILURE TENDS TO OCCUR DURING WARM WEATHER. THE FAILURE MILEAGES WAS 28000 AND THE CURRENT MILEAGE WAS 30000.
AT OUTSIDE TEMPERATURES ABOVE APPROXIMATELY 80 DEGREES, THE STEERING DEVELOPS A NOTCH OR DEAD SPACE THAT REQUIRES MORE THAN AVERAGE PRESSURE TO OVERCOME, THUS MAKING THE STEERING JERKY AND POTENTIALLY DANGEROUS IN AN EMERGENCY SITUATION. *TR

2003 BMW Z4 POWER STEERING BINDS UP DURING HIGH AMBIENT TEMPERATURES (OVER 90 F) ESPECIALLY WHEN THE CAR IS LEFT IN THE SUN ALL DAY. WHENEVER THE STEERING WHEEL IS NOT MOVING IT STICKS IN THAT POSITION REQUIRING TREMENDOUS FORCE TO GET IT TO MOVE FROM THAT POSITION AND TURN THE CAR. IT WILL STICK GOING DOWN THE ROAD THEN YOU HAVE TO FORCE IT TO BREAK LOOSE TO CORRECT THE CAR'S DIRECTION, THEN IT STICKS IN THIS NEW LOCATION AND YOU HAVE TO BREAK IT LOOSE TO RETURN THE WHEEL TO STRAIGHT AHEAD. WHEN YOU BREAK THE STEERING LOOSE IT MAKES AN AUDIBLE THUNK. THIS BEHAVIOR CAUSES THE CAR TO DIVE INTO THE NEXT LANE OR ONTO THE SHOULDER OF THE ROAD MAKING IT IMPOSSIBLE TO DRIVE AT HIGHWAY SPEEDS AND DANGEROUS TO EVEN DRIVE AT 35 MILES AN HOUR. THE BMW SERVICE DEPARTMENT CLAIMS THE CAR HAS NEVER EXHIBITED THIS BEHAVIOR FOR THEM, AND IT WILL COST $3700 TO REPLACE THE POWER STEERING. *TR

ODI has evaluated the sticky steering condition, which included reviews of complaints and warranty claims, interviews and surveys of owners of complaint vehicles, road tests of complaint vehicles, and a review of BMW's engineering and test data.ODI found the sticky steering condition does not result in a significant steering effort, thus the impact on the driver's ability to control the vehicle does not appear to be significant.A safety-related defect trend has not been identified at this time and further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.The agency will monitor the issue and reserves the right to take future action if warranted by the circumstances.See the attached report for additional information.In addition, during this investigation, ODI became aware of allegations of failure or loss of electric power-assisted steering on the subject vehicles.As a result, ODI is separately reviewing this issue to determine whether additional agency action is needed.
