IllustrationAT HIGH AMBIENT TEMPERATURES THE STEERING STICKS. IT SOMETIMES IS JUST A DISTRACTION, WHEN IT IS AT IT'S WORSE I BELIEVE IT IS DANGEROUS, NOT SO MUCH ON WIDE OPEN ROADS, BUT VERY MUCH SO ON NARROW ROADS. WHEN IT IS AT IT'S WORSE THE CAR MAY DART AS MUCH AS TWO FEET. *TR

BOUGHT USED 2004 BMW Z4 IN AUG 2012, STEERING SEEMED FINE, IT HAD 39K MILES ON IT. NOW AT 44K MILES THE STEERING HAS BECOME NOTCHY, WOBBLY FEELING AND THE CAR DARTS AROUND. HAD ALIGNMENT DONE IN JAN 2013 BUT STILL A PROBLEM. LOOKING AT THE NUMBER OF COMPLAINTS FILED ALREADY, I AM NOT ALONE. I WOULD BE HAPPY TO PAY OUT A SMALL AMOUNT TO FIX THIS BUT IT SEEMS TO BE A 3K-4K FIX FROM WHAT I'VE READ. BMW NEEDS TO RECALL OR ELSE COME UP WITH A FIX THAT DOESN'T INVOLVE REPLACING THE WHOLE STEERING COLUMN. WHAT DO YOU SAY BMW? *TR
STICKY STEERING PROBLEM, THIS WAS REPLACED IN 2006 UNDER WARRANTY BY BMW, AT ABOUT 2000 MILES. NOW FEB,2013 I HAVE THE SAME PROBLEM. I HAVE LESS THAN 12000 MILES ON VEHICLE. I FEEL THIS IS UNSAFE BECAUSE IT WILL CAUSE YOU TO JERK THE WHEEL THINK YOU NEED TO STEER HARD. *TR

THE STEERING WHEEL GETS STUCK WHILE DRIVING AND CAR DOESN'T STAY IN LANE INFACT NEEDS CONSTANT SIGNIFICANT ADJUSTMENTS TO KEEP IT FROM ACCIDENTALLY GETTING INTO ANOTHER LANE. THE ISSUE HAS OCCURRED MULTIPLE TIMES AND WAS AN INCONVENIENCE SO I DIDN'T PAY A LOT OF ATTENTION BUT IT'S MORE LIKE A SAFETY ISSUE NOW WITH CONTROLLING THE CAR BECOMING MORE AND MORE DIFFICULT ON FREEWAYS. NHTSA HAS IDENTIFIED THIS ISSUE PE10020 AS NOT SIGNIFICANT AND I SINCERELY HOPE THEY INVESTIGATE IT FURTHER AND TAKE SOME SERIOUS ACTION BEFORE IT CAUSES IRREPARABLE LOSS. BMW NEEDS TO OWN UP TO A MANUFACTURING DEFECT AS ITS NOT WEAR AND TEAR AND FIX THIS. *TR
WHILE DRIVING THE STEERING LIGHT COMES ON AND THE STEERING LOCKS IN PLACE. WHEN U TRY TO FORCE IT THE CAR STALLS OUT AND THE STEERING STAYS LOCKED .. EXTREMELY DANGEROUS!!! *TR
FOR SOME TIME MY BMW Z4 2004 HAS BEEN HAVING A "NOTCHY" FEEL TO THE STEERING. TODAY IT CAME TO A HEAD AS THE STEERING COMPLETELY LOCKED ON ME.

FOR SOME TIME MY BMW Z4 2004 HAS BEEN HAVING A "NOTCHY" FEEL TO THE STEERING. TODAY IT CAME TO A HEAD AS THE STEERING COMPLETELY LOCKED ON ME. I WAS 2 BLOCKS FROM HOME AFTER JUST EXITING A MAIN HIGH WAY I DRIVE EVERY DAY TO AND FROM WORK. I AM SO LUCKY I WAS ALREADY OFF THE MAIN ROAD OR A MAJOR ACCIDENT WOULD HAVE HAPPEND. NO STEERING, COMPLETELY LOCKED. I HAVE DONE MANY INTERNET SEARCHES AND APARENTLY I'M ONE OF MANY THAT HAVE HAD THIS ISSUE. FIX THE ISSUE BMW!!!!!!!!!!!!!!!! *TR

I RECENTLY BOUGHT THIS CAR AND THE DEALER TALKED ABOUT A STEERING ISSUE WITH THE Z4 MODELS WHERE THEY DON'T FEEL LIKE THE STEERING WILL CENTER. I DIDN'T HAVE A CHANCE TO PUT MILES ON THE CAR UNTIL TODAY WHERE I FOUND OUT WHAT HE WAS TALKING ABOUT AND HAD TIME TO RESEARCH IT. THIS IS A VERY WELL KNOWN ISSUE AND IT LOOKS LIKE YOU HAVE INVESTIGATED IT PREVIOUSLY BUT IT STILL IS A VERY REAL PROBLEM AND MAKES THE CAR UNSAFE TO DRIVE. WHILE DRIVING AFTER THE CAR IS WARMED UP THE STEERING WILL FEEL AS THOUGH IT STICKS AS YOU TRY TO DRIVE A STRAIGHT LINE. AT AROUND 40+MPH THE CAR WILL PULL RIGHT OR LEFT WITH THE STEERING NEARLY IMPOSSIBLE TO ADJUST TO CENTER. YOU CAN HAVE THE CAR PULLING TO ONE SIDE, SAY TRAVELING AT 60MPH, IT WILL PULL YOU TO THE RIGHT AT A RATE OF 2 FEET FOR EVERY SECOND. YOU HAVE TO NUDGE THE STEERING WHEEL AS IT IS NOT FLUID (FEELS LIKE IT IS STUCK) BACK TO THE LEFT AND THEN IT WILL PULL LEFT AT THE SAME RATE. IT IS A BATTLE OF CONSTANT ADJUSTMENT TO FIGHT IN TRYING TO CENTER THE CAR. IF YOU HAVE TRAFFIC AROUND YOU IT COULD BE AN ACCIDENT WAITING TO HAPPEN. I REQUEST THAT THIS ISSUE IS RE-OPENED AS A SAFETY RECALL. I HAVE REVIEWED THE INFORMATION YOU RECEIVED FROM BMW REGARDING STEERING WARRANTY CLAIMS AND WITH JUST OVER 12,000 BMW Z4'S PRODUCED AND NEARLY 10% (1,1XX) OF THEM HAVING A FILED CLAIM REGARDING STEERING ISSUES, ONE WOULD SEE THAT THIS IS A MAJOR FLAW. WARRANTY WORK IS NOT ALWAYS REQUESTED, THUS WHY THERE ARE STILL MORE ON THE STREET THAT NEED HIGH COST REPAIRS AND CAUSING UNSAFE DRIVING CONDITIONS FOR THE DRIVER/PASSENGER AS WELL AS SURROUNDING VEHICLES. *TR

TL* THE CONTACT OWNS A 2004 BMW Z4. THE CONTACT STATED THAT THE STEERING WHEEL SEIZED WITHOUT WARNING. THE CONTACT HAD TO WIGGLE THE STEERING WHEEL BACK AND FORTH IN ORDER TO CORRECT THE FAILURE. THE CONTACT TOOK THE VEHICLE TO THE DEALER AND WAS ADVISED THAT THE STEERING POWER ASSIST FOR THE STEERING NEEDED TO BE REPLACED. THE FAILURE MILEAGE WAS 20,000 AND THE CURRENT MILEAGE WAS 31,000. UPDATED 12/11/12*LJ UPDATED 12/12/12
WHILE DRIVING AT NORMAL SPEED THE STEERING BECAME STICKY AND MADE IT DIFFICULT TO MAINTAIN CONTROL OF THE CAR. MINOR STEERING ADJUSTMENTS ARE NEAR IMPOSSIBLE WITHOUT JERKING THE CAR FROM SIDE TO SIDE. THIS CAR IS EXTREMELY UNSAFE TO DRIVE WITH THIS CONDITION. *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.
