IN WARM WEATHER, AT HIGHWAY SPEEDS THE POWER STEERING STICKS AND THE WHEEL DOES NOT RETURN TO THE NEUTRAL POSITION ON IT'S OWN. AT TIMES THE WHEEL SEEMS TO TURN ON IT'S OWN AND YOU MUST CONSTANTLY HAVE A FIRM GRIP ON THE STEERING WHEEL READY TO CORRECT ANY UNWANTED MOVEMENT. *TR

1. THE VEHICLE WAS PARKED ALL DAY OUTDOORS ON A HOT SUNNY JULY DAY IN TEMECULA, CA. WHILE DRIVING IT HOME ON I15 AT APPROXIMATELY 70 MPH, THE STEERING WHEEL BECAME MUCH MORE DIFFICULT TO TURN AND WOULD NOT STAY ON CENTER, MAKING IT CHALLENGING TO SIMPLY STAY WITHIN MY LANE. THIS LASTED FOR 10-15 MINUTES, THEN THE STEERING RETURNED TO NORMAL. FORTUNATELY, THIS SECTION OF FREEWAY IS RELATIVELY STRAIGHT AND THE TRAFFIC HAPPENED TO BE MODERATE. 2. THIS FAILURE HAS OCCURRED ONLY ONCE IN THE 6 WEEKS I HAVE OWNED THE VEHICLE. 3. I HAVE NOT YET TAKEN STEPS TO CORRECT THE FAILURE. HOWEVER, I HAVE SEARCHED ONLINE FOR STEERING ISSUES WITH THIS YEAR, MAKE AND MODEL AND LEARNED THAT MANY OTHER OWNERS HAVE EXPERIENCED EXACTLY THE SAME ISSUE. THOSE WHO HAVE ATTEMPTED TO HAVE THE ISSUE CORRECTED BY THEIR LOCAL DEALERSHIP SAY THE REPAIR REPORTEDLY INVOLVES REPLACING THE ENTIRE STEERING COLUMN AT A COST OF NEARLY $4000. MY VEHICLE HAS UNDER 20,000 MILES BUT IS BEYOND THE 48 MONTH WARRANTY PERIOD. HAVING READ RECENTLY IN THE NEWSPAPER THAT NHTSA IS INVESTIGATING POWER STEERING ISSUES IN 2003-2005 BMW Z4'S, I AM TRYING TO FIND OUT IF THERE IS A KNOWN SOLUTION TO THIS PROBLEM THAT IS LESS COSTLY OR THAT IS COVERED BY THE MANUFACTURER BEFORE COMMITTING TO A $4000 REPAIR ON A LOW-MILEAGE USED VEHICLE THAT I ONLY RECENTLY PURCHASED. *TR
IN HOT WEATHER, STEERING GETS STICKY AND CAR BECOMES MORE DIFFICULT TO CONTROL. HAD REPAIRED ONCE BUT PROBLEM CONTINUES. VEHICLE HAS LESS THAN 10,000 MILES. *TR
MY COMPLAINT IS THAT THE STEERING WHEEL FEELS LIKE IT BINDS WHEN TURNING AND ALSO FEELS NOTCHY AND WILL NOT RETURN TO CENTER WHEN TURN IS COMPLETED. MOSTLY WHEN OUTDOOR TEMP IS WARMER THAN 80 DEGREES. *TR
WHEN MY Z4 HAS BEEN SITTING IN DIRECT SUN FOR A WHILE THE STEERING BECOMES STICKY. MAKING IT VERY DIFFICULT TO DRIVE. CAUSING THE CAR TO SWERVE INTO OTHER LANES. BMW HAVE QUOTED 3500 TO REPLACE THE STEERING COLUMN, I'M CURRENTLY NEGOTIATING WITH THEM TO REDUCE THIS COST. *TR
STEERING IS SOMETIMES "STICKY" -- WHEN THE STEERING WHEEL IS TURNED FROM ITS CURRENT STATIC POSITION, HIGHER THAN NORMAL RESISTANCE TO TURNING IS FELT.

STEERING IS SOMETIMES "STICKY" -- WHEN THE STEERING WHEEL IS TURNED FROM ITS CURRENT STATIC POSITION, HIGHER THAN NORMAL RESISTANCE TO TURNING IS FELT. ONCE THE INITIAL RESISTANCE IS OVERCOME, THE RESISTANCE LESSENS, RESULTING IN A TENDENCY TO TURN THE WHEEL FURTHER THAN WAS INTENDED. THIS MAKES IT DIFFICULT TO SMOOTHLY STEER THE CAR ON ITS INTENDED PATH AND RESULTS IN THE CAR WANDERING FROM SIDE TO SIDE. THE PROBLEM IS INTERMITTENT AND SEEMS TO HAPPEN ONLY IN HOT WEATHER. NO REPAIRS HAVE BEEN IMPLEMENTED YET TO THE VEHICLE (I HAVE ONLY RECENTLY ACQUIRED IT). *TR

2004 BMW Z4 STICKY STEERING WHEN IT'S HOT OUT. SOMETHING WITH THE POWER STEERING OR SOME OTHER STEERING COMPONENT MAKES IT SO THAT THE STEERING WHEEL TAKES EXTRA FORCE TO INITIATE A CHANGE IN THE POSITION OF THE WHEEL. THE EFFECT IS MOST NOTICEABLE AT SPEEDS 35MPH OR HIGHER, IT'S MOST PRONOUNCED AT HIGHWAY SPEEDS WHERE MINOR CORRECTIONS ARE IMPORTANT AND SHOULD NOT TAKE MUCH FORCE. THIS COULD EASILY RESULT IN TOO MUCH STEERING FORCE BEING USED IN THE WRONG SITUATION. *TR
2004 BMW Z4. MY POWER STEERING IS "STICKING" AS PER THE PE 10-020 INVESTIGATION. VERY DISCONCERTING WHEN EFFORT IS NEEDED TO "BREAK IT LOOSE" TO TURN THE WHEELS. RESULTS IN A "JERK" OF THE CAR IN THE DIRECTION OF THE TURN. *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.
