I AM STUCK WITH A 2004 Z4 WITH THE STICKY STEERING SYNDROME. AFTER IT IS WARMED UP THE STEERING STICKS IN POSITION AND IS DIFFICULT TO MOVE FROM POINT TO POINT. WE HAD BEEN DRIVING FOR 50 OR 60 MILES WITH THE TOP DOWN AND THE HEATER ON SO THE ENGINE WAS WARMED UP. THAT IS WHEN THE ISSUE FIRST APPEARED AND WE ALMOST HAD A HEAD ON ACCIDENT ON HIGHWAY 101 SOUTH OF CANNON BEACH, OREGON. THE SYNDROME SEEMS TO APPEAR ONLY AFTER THE CAR IS WARMED UP. WE BOUGHT THE Z4 ONE YEAR AGO AT ABOUT 37000 MILES AND THE CURRENT MILEAGE IS 42667. BMW REGIONAL MANAGEMENT HAS DECIDED NOT TO SUPPORT ANY REDUCTION OF THEIR $3259.00 CHARGE TO REPLACE THE STEERING MECHANISM WHICH IS SUPPOSED TO FIX THE PROBLEM. THE STICKY STEERING SYNDROME IS WELL KNOWN AS A SAFETY HAZARD ON THE NHTSA SITE AND ELSEWHERE ON THE WEB YET NOTHING HAS BEEN DONE ABOUT IT TO THIS DATE. THIS LOOKS LIKE ANOTHER TOYOTA LIKE SAFETY ISSUE. IS THE NHTSA LISTENING OR DOES SOMEONE NEED TO DIE BEFORE A RECALL IS ISSUED? *TR

AFTER THE CAR SITS IN THE HOT SUN (ANYWHERE ABOVE 75 DEGREES) THE STEERING STARTS BINDING/LOCKING UP AT ALL SPEEDS. ALTHOUGH IT SEEMS TO BE WORSE WHEN DRIVING AT HWY SPEEDS. WHEN DRIVING AROUND A SLIGHT CURVE THE STEERING DOES NOT RETURN TO CENTER AS IT SHOULD NOR IS IT EASY TO GET THE CAR TO STRAIGHTEN BACK OUT. I HAVE TO FORCE IT BACK TO CENTER WHICH USUALLY ENDS UP CAUSING ME TO OVER CORRECT AND MOVE CLOSE TO OR IN THE OTHER LANE. I FIRST NOTICED THE PROBLEM LAST SUMMER, BUT SINCE I ONLY DRIVE THE CAR ON WEEKENDS I DIDN'T PAY MUCH ATTENTION TO IT LAST SUMMER. IT WAS FINE DURING THE WINTER, BUT GOT SIGNIFICANTLY WORSE WHEN IT GOT WARM THIS YEAR. I TOOK MY CAR TO BMW OF NASHVILLE AND WAS TOLD THAT THE PROBLEM WAS THE STEERING COLUMN AND THAT IT NEEDED TO BE REPLACED. (I'M CURRENTLY WAITING ON THE REPLACEMENT COLUMN TO COME IN AND BE REPLACED) AFTER DOING SOME RESEARCH ABOUT THE PROBLEM I'VE FOUND THAT THERE ARE HUNDREDS OF OTHER Z4 OWNERS THAT HAVE EXPERIENCED THE SAME PROBLEM AND BMWNA HAS NOT ACKNOWLEDGED THAT THERE IS A PROBLEM. I CONTACTED BMWNA MYSELF AND ALTHOUGH THEY DIDN'T ACKNOWLEDGE THERE WAS A PROBLEM, THEY DID OFFER ME A 10% DISCOUNT ON THE $3900.00 REPAIR. I BELIEVE THIS IS A FACTORY DEFECT IN THE CAR AND THAT THEY ALL SHOULD BE RECALLED BEFORE SOMEONE GETS KILLED IF THERE HAVEN'T ALREADY BEEN FATAL ACCIDENTS. *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.
