HAVE HAD THE CAR FOR SEVERAL YEARS AND HAVE NOTICED A STEERING ISSUE THAT SEEMS TO BE GETTING WORSE. I RESEARCHED THIS ON MULTIPLE FORUMS AND IT APPEARS THAT THERE ARE NUMEROUS EXAMPLES OF SIMILAR PROBLEMS. MOST RELATE TO ISSUES IN HOT TEMPATURES, MINE IS MORE RELATED TO SPEED. PROBLEM WAS VERY NOTICABLE LAST EVENING AT 70 DEGREES. HERE ARE THE SYMPTOMS... AT LOW SPEEDS (UNDER 20MPH) STEERING IS VERY LIGHT AND SMOOTH, NO ISSUES AT ALL. AS SPEED INCREASES, THE STEERING GETS HEAVIER (AS IT SHOULD) BUT DEVELOPS A "DETENT" AT STRAIGHT CENTER. THE FASTER THE SPEED, THE MORE EFFORT NEEDED TO OVERCOME THE DETENT RESISTANCE, TO THE POINT THAT IT BECOMES EASY TO OVERSTEER THE CAR. THIS CAN BE REAL SCARY DURING AVOIDANCE MANEUVERS AND QUICK LANE CHANGES. I HAVE HAD MY CAR WORKED ON FOR OTHER SERVICE AND THE MECHANIC ALSO NOTICED THE ISSUE AS IT WAS DRIVEN TO HAVE THE WHEELS ALIENED.

STIFF STEERING WHEN THE TEMPERATURE RISES. THERE IS RESISTANCE TURNING LEFT OR RIGHT OFF CENTER. OFF RAMPS SEEM TO BE THE MOST DANGEROUS BECAUSE ONCE I TURN RIGHT OFF CENTER THE VEHICLE WANTS TO CONTINUE TURNING RIGHT. THIS HAS HAPPENED EVERY TIME I'VE DRIVEN THIS VEHICLE WHEN THE TEMPERATURE IS ABOVE 85 DEGREES.

AFTER THE CAR IS PARKED OUT IN THE SUN ON A HOT DAY (80F OR HIGHER) THE CAR IS DIFFICULT TO STEER IMMEDIATELY WHILE IN FORWARD MOTION. THE DIFFICULTY CAN BE DESCRIBED AS TRYING TO TURN THE STEERING WHEEL EITHER LEFT OR RIGHT REQUIRES SO MUCH FORCE THAT ONCE IT TURNS YOU OVER STEER AND NEED TO TURN THE WHEEL THE OTHER DIRECTION TO STAY WITHIN THE LANES ON THE ROAD. ANY BEND IN THE ROAD IS DIFFICULT TO KEEP THE CAR CENTERED IN THE LANE SINCE TURNING THE WHEEL REQUIRES SO MUCH FORCE THAT OVER STEERING IS CONTINUALLY HAPPENING. THIS CONDITION DOESN'T APPEAR WHEN THE CAR IS COLD OR PARKED IN A GARAGE ON A HOT DAY THEN DRIVEN FOR 30 MINUTES. LATER THOUGH IT MAY START TO OCCUR AFTER 30 MINUTES OF DRIVING ON A VERY HOT DAY IN THE SUN AS THE CAR GET HOT.

I BOUGHT A 2005 BMW Z4 ABOUT A MONTH AGO. THE FIRST COUPLE OF WEEKS, EVERYTHING WAS FINE. HOWEVER, AS THE TEMPERATURE OUTSIDE ROSE, I NOTICED THAT THE STEERING STARTED STICKING, MAKING IT HARD TO DRIVE. FOR EXAMPLE, YESTERDAY, AS I WAS CHANGING LANES ON A LOCAL HIGHWAY, I HAD TROUBLE CHANGING LANES, AND ALMOST HIT ANOTHER CAR BECAUSE OF THE STICKING PROBLEM. BASED ON WHAT I'VE HEARD, I BELIEVE THIS PROBLEM IS BEING CAUSED BY A DEFECTIVE BEARING IN THE STEERING COLUMN.

STEERING COLUMN EXPERIENCE SUDDEN JERKS TO THE LEFT, OR TO THE RIGHT RANDOMLY MAKING THE CAR REALLY DIFFICULT TO DRIVE SAFELY. IT'S WORSE WHEN DRIVING ON A HIGHWAY. ALL TIRES PSI ARE NORMAL AND TIRES JUST BRAND NEW. CAR WAS ALIGNED TO DISCARD EVERYTHING. EVEN WITH MANY SIMILAR ISSUES FROM OTHER CUSTOMERS BMW IS NOT ACCEPTING THIS FAILURE AS ONE TO RECALL. BUT WHEN I GETS INTO THE DEALERSHIPS THEY DIAGNOSE THAT THE HOLE STEERING COLUMN NEEDS TO BE REPLACED AT MY EXPENSE. MY CAR HAS ONLY 86,000 MILES AND THIS IS BEEN HAPPENING SINCE VEHICLE HAD 80,000 MILES.

AFTER THE CAR IS PARKED IN THE HOT SUN ALL DAY, THE STEERING OF THE VEHICLE GETS "STUCK". IT IS HARD TO STEER AND STAY SMOOTH IN THE LANE BECAUSE YOU ARE STRUGGLING TO GET THE STEERING UNSTUCK AT 70MPH DOWN THE INTERSTATE. THIS IS A VERY SERIOUS AND DANGEROUS PROBLEM THAT NEEDS TO BE REVISITED. MY CAR ONLY HAS 31K MILES ON IT.

ABOVE 30 MPH STEERING STICKS AND REQUIRES GREATER EFFORT TO TURN. AT ANY HIGHWAY SPEED THIS REQUIRES OVERCORRECTION AND IS VERY DANGEROUS. THIS REQUIRES IMMEDIATE ATTENTION AND REMOVES OF THOUGHT OF "PLEASURE DRIVING"

STEERING FEELS LIKE IT IS IN A GROOVE AND IT TAKES DRAMATIC EFFORT TO MAKE A STEERING CORRECTION TO STAY IN A LANE. ONCE CORRECTED THE CAR SWERVES UNTIL YOU CORRECT AGAIN. THE CAR IS VERY UNSAFE TO DRIVE IN THIS CONDITION. REVIEW OF COMPLAINTS AND AVAILABLE INFORMATION CONFIRM THAT THIS IS A BMW ISSUE WORTHY OF A RECALL. THERE WILL BE INJURIES AND DEATHS IF THIS PROBLEM IS NOT CORRECTED. THE COST OF THE REPAIR PROHIBIT MOST PEOPLE FROM OBTAINING DEALER ASSISTANCE TO CORRECT THE ISSUE.

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.
