Illustration2003 BMW Z4. THE STEERING BINDS WHEN THE OUTSIDE TEMPERATURE IS ABOVE 80 DEGREES. THIS IS DANGEROUS WHEN I HAVE TO OVERCORRECT TO KEEP THE CAR ON THE ROAD. THE DEALER SAYS THAT THIS IS A KNOW PROBLEM, BUT NOT A SAFETY ISSUE AND THERE IS NOT A FIX AVAILABLE. THIS IS DEFINITELY A SAFETY ISSUE.

WE HAVE A 2003 BMW Z4, 3.0L, AUTO. EVER SINCE IT WAS NEW, IT HAS EXHIBITED AN IRREGULARITY IN THE (ELECTRIC) STEERING. IT ONLY MANIFESTS ITSELF WHEN THE OUTSIDE TEMERATURE IS FAIRLY HOT, SAY OVER 85 DEGREES. THE ISSUE IS THAT THE STEERING EXHIBITS A "STICKING" OR "NOTCHINESS" THAT MAY BE OR BECOME A SAFETY ISSUE FOR DRIVERS IF THE CAR NO LONGER RESPONDS TO STEERING INPUTS IN THE SAME MANNER IT DOES WHEN THIS ISSUE IS NOT PRESENT. TO-DATE THIS ISSUE HAS BEEN EXPERIENCED AND DOCUMENTED BY OWNERS THROUGHOUT THE COUNTRY ON AN OWNERS FORUM AT HTTP://BIMMER.ROADFLY.COM/BMW/FORUMS/E85/. AFTER 2 TRIPS TO THE DEALERSHIP FOR SERVICE, WHERE THIS ISSUE WAS BROUGHT TO THEIR ATTENTION,WE'VE BEEN INFORMED THAT BMWNA HAS NOT RECOGNNIZED THAT THERE IS AN ISSUE AND THEREFORE THERE IS NO "FIX' IN THE WORKS.

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.
