411 reportsI PREVIOUSLY FILED A REPORT ABOUT THE ELECTRONIC STEERING WHEEL COLUMN, POOR STEERING, STICKING PRIOR TO HAVING IT FIXED ON THIS DATE. I HAD NOT FOUND THE PAPERWORK FOR IT UNTIL AFTER I SUBMITTED THE REPORT. THE TRACKING # 11300634.
I HAD THIS CAR BUILT AND AM THE ONLY OWNER. INITIALLY, STILL UNDER WARRANTY, THE CAR NEEDED A NEW CONVERTIBLE TOP. AFTER THAT, FOR YEARS, I HAD A 'STICKING' WHEN I WOULD STEER THE CAR MAKING THE CAR VERY DIFFICULT TO CONTROL OR TURN.

I HAD THIS CAR BUILT AND AM THE ONLY OWNER. INITIALLY, STILL UNDER WARRANTY, THE CAR NEEDED A NEW CONVERTIBLE TOP. AFTER THAT, FOR YEARS, I HAD A 'STICKING' WHEN I WOULD STEER THE CAR MAKING THE CAR VERY DIFFICULT TO CONTROL OR TURN. THIS DETERRED ME FROM DRIVING THE CAR AS MUCH AS I WANTED, AND CERTAINLY FROM TAKING IT ON ANY DISTANCE TRIPS....BASICALLY ENJOYING THE CAR. INITIALLY I THOUGHT THE CAR MAY NEED NEW TIRES OR AN ALIGNMENT, BUT IT WAS DIAGNOSED AS THE ELECTRONIC STEERING COLUMN. FROM READING BMW CHATS AND FORUMS, I FOUND THIS WAS A VERY COMMON PROBLEM. I TRIED TO CONTACT BMW DIRECTLY, BUT TO NO AVAIL. I FINALLY HAD TO PAY FOR THE REPAIRS MYSELF, COSTING OVER $3000. THE OTHER PROBLEM THAT HAS CONTINUED IS THE ABS BRAKE LIGHT WILL ILLUMINATE FOR NO APPARENT REASON. I HAVE HAD MY MECHANIC LOOK AT IT, BUT CAN'T SEEM TO FIND A DEFINITIVE CAUSE. OFTEN WHEN THE CAR IS TURNED OFF, AND THEN RESTARTED, THE LIGHT GOES OFF...BUT WILL SOMETIMES, NOT ALL THE TIME, COME BACK ON AGAIN, BOTH AT HIGHER SPEEDS AND ALSO DURING CITY, LOW SPEED DRIVING. I BABY THIS CAR SO MUCH, ONLY DRIVE IT SEASONALLY, AND IT SEEMS TO SPEND MORE TIME IN THE SHOP BEING REPAIRED OR MAINTAINED. I THINK IT WAS A 'LEMON' FROM THE ONSET. BMW WAS NEGLIGENT IN HELPING COVER SOME EXPENSES THAT MANY OTHERS HAVE REPORTED!
POWER STEERING IS INTERMITTENT. ALMOST NEVER WORKS WHEN FIRST STARTED BUT AFTER DRIVING FOR 20-30 MINUTES, IF I TURN THE CAR OFF AND BACK ON AGAIN, IT WORKS AND THE DASH LIGHT GOES OUT. I CAN EVEN DO IT WHILE DRIVING, SHIFTING TO NEUTRAL, TURN CAR OFF AND THEN BACK ON AND THE POWER STEERING COMES BACK ON. VERY FRUSTRATING TO …

POWER STEERING IS INTERMITTENT. ALMOST NEVER WORKS WHEN FIRST STARTED BUT AFTER DRIVING FOR 20-30 MINUTES, IF I TURN THE CAR OFF AND BACK ON AGAIN, IT WORKS AND THE DASH LIGHT GOES OUT. I CAN EVEN DO IT WHILE DRIVING, SHIFTING TO NEUTRAL, TURN CAR OFF AND THEN BACK ON AND THE POWER STEERING COMES BACK ON. VERY FRUSTRATING TO DRIVE LIKE THIS ... AND DANGEROUS TOO!
1)IT KEEPS PULLING TO THE LEFT, OR TO THE RIGHT. IT REQUIRES CONSTANT ADJUSTMENTS SO THAT I COULD KEEP THE CAR ALIGNED, OR CENTERED. 2)I EXPERIENCE SUDDEN JERKS TO THE LEFT, OR TO THE RIGHT WHEN THE ROAD SURFACE IS SLIGHTINGLY UNEVEN.

I CAN NEVER PREDICT WHICH WAY THE CAR PULLS ME. I STRUGGLE A LOT TO KEEP THE STEERING CENTERED WHEN STOPPING AT ANY RED LIGHTS. 3) SOMETIMES, THE STEERING FEELS LIKE IT IS STUCK. AFTER REVIEW ONLINE, THIS SEEMS TO BE A VERY COMMON PROBLEM.
THIS IS A REOCCURRING PROBLEM WHICH I HAVE ATTEMPTED TO ADDRESS THROUGH BOTH LOCAL MECHANICS AND BMW WITH NO RESULTS. ESSENTIALLY, WHILE MOVING AT SLOW SPEEDS OR STOP AND GO TRAFFIC, THE ELECTRICAL SYSTEM "SHUDDERS", ALL INSTRUMENT LIGHTS ILLUMINATE, THE TRANSMISSION SHIFTS TO NEUTRAL, AND THE ENGINE SHUTS DOWN THEN RESTARTS.

THIS IS A REOCCURRING PROBLEM WHICH I HAVE ATTEMPTED TO ADDRESS THROUGH BOTH LOCAL MECHANICS AND BMW WITH NO RESULTS. ESSENTIALLY, WHILE MOVING AT SLOW SPEEDS OR STOP AND GO TRAFFIC, THE ELECTRICAL SYSTEM "SHUDDERS", ALL INSTRUMENT LIGHTS ILLUMINATE, THE TRANSMISSION SHIFTS TO NEUTRAL, AND THE ENGINE SHUTS DOWN THEN RESTARTS. THE FAILURE OCCURS ON AN IRREGULAR BASIS, AFFECTING PRIMARILY THE EPS LIGHT, BUT MAY ALSO AFFECT ALL LIGHTS IN THE INSTRUMENT CLUSTER. LIKEWISE, IT MAY OR MAY NOT MOVE MY TRANSMISSION TO NEUTRAL AND IF THAT HAPPENS, MAY OR MAY NOT ALLOW MY TO PLACE IT BACK IN DRIVE WITHOUT SHUTTING THE VEHICLE DOWN FOR SEVERAL MINUTES. TO DATE, BOTH THE ALTERNATOR AND THE IGNITION SWITCH HAVE BEEN REPLACED, NO RESULTS. A BRIEF SEARCH OF POPULAR BMW FORUMS FINDS SIMILAR DESCRIPTIONS FROM OTHER OWNERS.
AFTER STARTING CAR, EPS LIGHT COMES ON AND STEERING IS VERY TIGHT, NEAR IMPOSSIBLE TO TURN OR MANEUVER IN PARKING LOTS, ETC.
WHEN DRIVING AT HIGHWAY SPEEDS AND MORE SO WHEN THE TEMP IS WARM OR STEERING COLUMN HAS WARMED UP THE STEERING BECOMES "STICKY", IN THAT IT TAKES AN EFFORT TO OVERCOME THE SPOT IT IS IN AS OPPOSED TO SMOOTHLY MOVING/STEERING LEFT OR RIGHT.

WHEN DRIVING AT HIGHWAY SPEEDS AND MORE SO WHEN THE TEMP IS WARM OR STEERING COLUMN HAS WARMED UP THE STEERING BECOMES "STICKY", IN THAT IT TAKES AN EFFORT TO OVERCOME THE SPOT IT IS IN AS OPPOSED TO SMOOTHLY MOVING/STEERING LEFT OR RIGHT. IT IS UNCOMFORTABLE TO STEER WITH ONE HAND (6 SPD MANUAL TRANSMISSION) AS IT FEELS LIKE YOU ARE GOING TO OVER CORRECT THE STEERING WHEN TRYING TO MAKE MINOR ADJUSTMENTS TO MAINTAIN DRIVING DOWN THE CENTER OF YOUR LANE. ESPECIALLY WHEN DRIVING IN HEAVY FREEWAY TRAFFIC! I35W MINNEAPOLIS, MN
STICKING STEERING WHEN WARM WHILE DRIVING
THE VEHICLE HAS INTERMITTENT LOSS OF POWER STEERING WHICH MAKES IT VERY DIFFICULT TO DRIVE, STEER AND CONTROL WHEN IN MOTION. I WAS ABLE TO AVOID SERIOUS ACCIDENTS BY LITERALLY CRAWLING ALONG THE SIDE OF THE ROAD WITH FLASHERS ON SO OTHER DRIVERS WOULD STAY CLEAR. THIS HAS HAPPENED ON MORE THAN ONE OCCASION.
Official recalls
104V182000 · Fuel System, Gasoline:delivery:fuel Pump
Apr 12, 2004
ON CERTAIN PASSENGER VEHICLES, UNDER CERTAIN ENVIRONMENTAL CONDITIONS, A VAPOR LOCK IN THE FUEL PUMP COULD OCCUR CAUSING THE ENGINE TO STALL. IF THIS WERE TO HAPPEN, THE ENGINE WOULD NOT BE ABLE TO BE RESTARTED FOR APPROXIMATELY 15 TO 20 MINUTES.
Consequence & remedy
Consequence: IF STALLING WERE TO OCCUR, THE DRIVER WOULD BE UNABLE TO MAINTAIN VEHICLE SPEED OR ACCELERATE, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL INSTALL A RESISTOR IN THE ELECTRICAL LINE POWERING THE FUEL PUMP IN ORDER TO PREVENT AN OCCURRENCE OF VAPOR LOCK. THE RECALL BEGAN MAY 11, 2004. OWNERS SHOULD CONTACT BMW AT 1-800-831-1117.

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.
