THE STEERING HAS A LOUD POPPING SOUND WHEN TURNED TO THE LEFT OR RIGHT. STEERING HAS BECOME STIFF. A MECHANIC IS DOING A THOROUGH INSPECTION AND WE ARE AWAITING HIS FINAL ANALYSIS OF THIS PROBLEM.

TL* THE CONTACT OWNS A 2004 BMW Z4. THE CONTACT STATED THAT WHEN THE VEHICLE WAS SITTING IDLE FOR LONG PERIODS, THE STEERING WHEEL WOULD BECOME TIGHT AND WOULD NOT OPERATE PROPERLY. WHEN THE CONTACT WAS FINALLY ABLE TO MANEUVER THE STEERING WHEEL IT WOULD ONLY MOVE IN ONE DIRECTION. ONCE THE VEHICLE WAS TURNED ON AND WARM, THE STEERING WHEEL WOULD OPERATE NORMALLY. THE VEHICLE WAS TAKEN TO A PERSONAL MECHANIC WHO CONFIRMED THAT THE FAILURE WAS WITHIN THE STEERING COLUMN, BUT WAS NON-REPAIRABLE. THE VEHICLE WAS NOT REPAIRED. THE VIN WAS UNAVAILABLE. THE FAILURE MILEAGE WAS 25,000 AND THE CURRENT MILEAGE WAS 53,000.
VEHICLE HAS A STEERING ISSUE WHERE IT BECOMES 'STICKY'; IT HOLDS VERY TIGHTLY TO THE CENTER POSITION AND IS DIFFICULT TO TURN. ONCE IT 'BREAKS FREE', IT TURNS SUDDENLY AND IS VERY DIFFICULT TO CONTROL. THE BEHAVIOR IS INTERMITTENT AND TENDS TO EXHIBIT ITSELF ON HOT DAYS. *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.
