I WAS APPROACHING A TRAFFIC SIGNAL AND I HAD TO STOP. I BEGAN EASING UP ON THE BRAKE PEDAL AS THE CAR WAS COMING TO A STOP. IT WAS THEN THAT I REALIZED I WAS HAVING TO PRESS HARDER ON THE BRAKE PEDAL AS THE CAR WAS NOT MAINTAINING THE SLOW SPEED I WAS EXPECTING. HAVING REACHED THE POINT AT WHICH I HAD TO STOP, I FOUND MYSELF PRESSING QUITE HARD ON THE BRAKE PEDAL. I IMMEDIATELY PUT THE CAR INTO NEUTRAL AND NOTICED THE TACHOMETER READING 3,500 TO 4,000 RPM'S. I BELIEVE IT WAS MY TAPPING ON THE GAS PEDAL THAT GOT THE CAR TO REV AT THE NORMAL RPM'S FOR A CAR THAT IS A STATIONARY POSITION, HOWEVER, THIS HAPPENED SO FAST AND CAUGHT ME OFF GUARD, THAT PERHAPS THE PROBLEM FIXED ITSELF AND IT WASN'T MY TAPPING ON THE GAS PEDAL. *NLM

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.
