WHEN THE CAR SITS IN DIRECT SUNLIGHT FOR AN EXTENDED PERIOD OF TIME THE STEERING BECOMES DIFFICULT TO CONTROL WITH NO CENTER BALANCE. THE ONLY WAY TO CORRECT THIS ISSUE IS TO PARK THE CAR IN THE SHADE AND WAIT FOR THE STEERING TO RETURN TO NORMAL. *JB

WHEN TEMPERATURES ARE ABOVE 80F THE STEERING STICKS AND REQUIRES MORE INPUT TO OVERCOME THE RESISTANCE. ONCE IT OVERCOMES THE RESISTANCE IT OVER CORRECTS SO THAT YOU HAVE A ZIG ZAG DRIVING PATTERN. I WAS TOLD BMW IS AWARE BUT THERE IS NO FIX ALTHOUGH ONLINE MESSAGE BOARDS STATE MANY HAVE HAD THEIR CARS REPAIRED. *NM

PROBLEM: EPS STEERING GETS VERY STICKY AFTER CAR HAS SAT IN DIRECT SUNLIGHT FOR A FEW HOURS. MINOR STEERING CORRECTIONS ARE NEARLY IMPOSSIBLE. PROBLEM CLEARS UP AFTER CAR HAS BEEN GARAGED FOR A COUPLE HOURS AND ALLOWED TO COOL. THIS PROBLEM MAKES THE CAR FEEL VERY UNSAFE TO DRIVE. I AM CONSTANTLY WORRIED IT MIGHT FAIL ENTIRELY AT SOME POINT -- HOPEFULLY NOT WHILE I AM DRIVING IT. PROBLEM WAS FIRST NOTICED AT THE END OF SUMMER LAST YEAR (2004). CAR WAS PURCHASED IN JULY. THIS YEAR, IT HAS BEGUN ALREADY (SINCE MID-APRIL 2005).

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.
