I HAVE MAJOR PROBLEMS WITH THE STEERING WHEEL OF MY 2005 BMW Z4 3I, PURCHASED AS A CERTIFIED PRE-OWNED CAR FROM A BMW DEALER. IT HAD ABOUT 11K MILES ON IT. SINCE THEN I HAVE BEEN EXPERIENCING THIS PROBLEM DESCRIBED BELOW. I HAVE NOT HAD ANY ACCIDENT WITH IT, BUT THIS IS A COMPLAINT THAT THERE MAY ME A SAFETY ISSUE WITH THE STEERING WHEEL OF THE CAR. 1)IT KEEPS PULLING TO THE LEFT, OR TO THE RIGHT ESPECIALLY AT LOWERS SPEEDS SAY BELOW 60 MI/HR. IT REQUIRES CONSTANT ADJUSTMENTS SO THAT I COULD KEEP THE CAR ALIGNED, OR CENTERED WHILE DRIVING. 2) THE CAR PULLS ME TO THE LEFT, OR TO THE RIGHT SUDDENLY WHEN THE ROAD SURFACE IS SLIGHTINGLY UNEVEN, ESPECIALLY IN LOWER SPEEDS. I CAN NEVER PREDICT WHICH WAY THE CAR PULLS ME. IT CAN BE VERY STRUGGLING TO KEEP THE STEERING UNDER CONTROL WHEN STOPPING AT ANY RED LIGHTS BECAUSE OF THESE SUDDEN JERKS IN THE STEERING, OR PULLS IN THE STEERING WHEEL. 3) SOMETIMES, THE STEERING FEELS LIKE IT IS STUCK, OR LOCKED IN A WAY THAT I FEEL LIKE I COULD NOT CONTROL IT. THIS USUALLY HAPPENS WHEN THE WEATHER IS HOT, OR AT HIGHER HUMIDITY. 4) I TOOK THE CAR TO THE DEALER TWO YEARS AGO WHEN I STILL HAD THE WARRANTY, AND THEN THEY REPLACED THE STEERING COLUMN AND ALIGNMENT WAS MADE AFTER THE REPLACEMENT. HOWEVER, THE SYMPTOMS DID NOT GO AWAY AT ALL. I TOOK THE CAR TO ANOTHER DEALER; I WAS TOLD THAT IT JUST REQUIRED AN ALIGNMENT WHICH WAS ALREADY DONE AFTER THE REPLACEMENT OF THE STEERING COLUMN. SO, THERE SHOULD NOT BE AN ALIGNMENT RELATE PROBLEM. IF THE ONLY PROBLEM WAS THE ALIGNMENT PROBLEM, THE CAR SHOULD HAVE PULLED EITHER TO THE LEFT, OR TO THE RIGHT, NOT TO THE BOTH DIRECTIONS. 5) I BELIEVE IF ANY ELDERLY PERSON, OR SOMEONE WITH SLOWER REFLEX, TRIES TO DRIVE THIS CAR WITH SUCH PROBLEMS MAY END UP HAVING A CATASTROPHIC CRASH. MAINLY BECAUSE, THE DRIVER MUST PAY LOTS OF ATTENTION TO KEEP THE CAR CENTERED, OR THE STEERING UNDER CONTROL. OTHERWISE, AT ANY SECOND YOU MAY FIND YOURSELF SOMEWHERE OFF THE ROAD. *TR

I'M EXPERIENCING VERY STIFF OR STUCK STEERING. IT SEEMS TO ONLY OCCUR DURING THE SUMMER MONTHS, BUT MAINLY WHEN MY CAR IS LEFT OUT IN THE SUN AT WORK, THE DRIVE HOME IS QUITE AN ADVENTURE. KEEPING THE CAR DRIVING STRAIGHT IS NO EASY TASK, TRYING TO MAKE A SMALL CORRECTION RESULTS IN THE STEERING WHEEL MOVING A GREAT DISTANCE AS ONE HAS TO APPLY MORE FORCE TO THE STEERING WHEEL TO OVERCOME THE "STUCKNESS". THIS RESULTS IN A OVER CORRECTION OF STEERING AND PUSHES THE CAR TO OPPOSING LANES AT THE EXTREME, OR OTHERWISE JUST MAKES THE CAR JERK FROM SIDE TO SIDE. I'VE HAD NIELLO BMW OF SACRAMENTO LOOK AT THIS, AND THEY FOUND NOTHING NOR ADMITTED THIS WAS A PROBLEM. AS THE SUMMER MONTHS COME AROUND, MY STEERING IS GOING BACK TO IT'S USUAL JERKINESS. *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.
