There are 50 owner-reported steering complaints for the 2003 BMW Z4in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Steering is binding up, very hard to steer and control. Car starts out running fine after parked in hot weather and restarted it is almost uncontrollable. Looking for corrective action. Only 39,920 miles on car. Would like to use it or sell it, can do neither in current condition. Steering column needed or components
When outside temp is 80degrees or higher it becomes difficult to maintain the vehicle in the correct driving lane due to a stickyness in the steering wheel. I will not allow anyone to drive the vehicle when the temp is over 80 degrees ... sucks to have a convertable that you can't drive in warm weather!
My girlfriend, [XXX] , purchased a used 2003 BMW z4 2.5i. It is pristine with 47K original miles. Always maintained, garaged and never driven in foul weather. I, [XXX] , drove it home for her and noticed the steering to be "sticky". This showed on the highway traveling at 65 MPH. It was very unsettling to feel the car want to track in a direction that i could not control. I used "more force" to pull the steering wheel to get tracking correctly and stay in my travel lane. Lucking I did not overcorrect and lose control or cause and accident. Once it happened it continued to happen the balance of the drive on the highway and back roads. I've owned and driven many different makes and models of vehicles from Dodge, Renault, Toyota, GMC, Chrysler, Volvo, Geo, etc. and never has "steering" been an issue. Once we got home I looked up "sticky steering" issue for the 2003 Z4 and this is a known issue. Driving this BMW was unsettling and unsafe. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Upon starting the car, power steering does not work making car unmanueverable.
Sticky steering steering wheel hard to turn and stops intermittently when outside temperature is hot
The steering in this BMW Z4 gets "sticky" in warm or hot weather. It drives fine in cold weather. The steering has to be constantly corrected as it pulls to the left. It will not track in a straight line and needs constant corrections from side to side to compensate for the problem. If you do not pay close attention and correct the steering input, you will go off the road. On a warmer day after driving for a while I suddenly experienced a unexpected binding of the steering and almost ended up steering into oncoming traffic. This car is not safe to drive. The 2003 model has electric power steering. There are no codes or warning lights. I took the car to the local mechanic and he was easily able to reproduce the issue when he drove it less than 1 mile. This issue not only puts me at risk but others because of the constant correction of the steering to keep a straight. If you drive this car in warm or hot weather distances more than 20 miles then shut if off, then attempt to restart there is no steering at all. Please view the 2 websites listed below from BMW owners. https://automotivesblog.com/e85-e86-bmw-z4-steering-problems-how-to-fix/ https://www.carproblemzoo.com/bmw/z4/steering-problems.php One website had almost 700 complaints with the steering. I dare not let my kids behind the wheel of this car. It is not a question of "if" someone gets killed, but "when." BMW North America would only say there are no recalls. When I asked if there have been issues reported, they declined to give me that information. Please help. It would be interesting to know how many accidents were listed with the steering being the cause of the MVA. I would gladly allow someone with the NHTSA drive this car in warm weather. Then you would see how dangerous the steering is in these vehicles.
STICKY STEERING AFTER CAR WARMS UP. STEERS LIKE A BOAT. DANGEROUS AT HIGHWAY SPEEDS OR WINDING ROAD.
Car has 15,000 miles and always stored in climate controlled garage. Drove it today and within 1/2 mile the electronic power steering failed making it very, very hard to steer. Shut vehicle off and restart and the problem goes away but only for a minute or two and then returns.
During very warm days in the summer the steering wheel tends to stick during turns. It requires extra force to continue to turn the wheel which becomes problematic during a tight turn or on highway on-ramps.
On hot days the steering becomes sticky like there is a catch. It will also pull to one side or the other making it very dangerous to drive especially on the interstate.
I JUST PURCHASED Z4. DID NOT NOTICE ANY PROBLEM DURING TEST RIDE. ON MY WAY HOME DURING PURCHASE STEERING BECAME AN ISSUE. THE CAR WOULD BE DRIVING FINE THEN WHAT I WOULD A DEAD SPOT WOULD APPEAR. THE STEERING WHEEL WILL SUDDENLY SHIFT LEFT OR RIGHT WHAT SEEMS A FEW INCHES. THIS CAUSES DRIVER (ME) TO COMPENSATE TO AVOID GOING IN DITCH OR CROSSING A LANE OR GETTING INTO AN ACCIDENT. THIS HAPPENED MANY TIMES ON MY 70-MILE TRIP HOME.
THE FIRST ISSUE IS THAT THE POWER STEERING WILL GO OUT DURING NORMAL OPERATION OF THE VEHICLE MAKING THE WHEEL HARD TO TURN. ADDITIONALLY, AT RIGHT ABOUT THE STRAIGHT POSITION OF THE STEERING WHEEL THE STEERING WILL STICK (CONSISTENTLY FIGHTING THE WHEEL TO STAY CENTERED). STAYING STRAIGHT IS NEARLY IMPOSSIBLE AS YOU CONSTANTLY BATTLE THE RESISTANCE BACK AND FORTH TO KEEP THE VEHICLE MOVING IN A STRAIGHT LINE. IT IS QUITE DISCONCERTING AND HAS ALMOST RESULTED IN ME SIDE SWIPING ONCOMING VEHICLES ON SEVERAL OCCASIONS. I HAVE LEARNED THAT THIS IS A COMMON PROBLEM THAT BMW NEVER ADDRESSED. RESEARCHING THE MATTER I'VE LEARNED THAT A STEERING COLUMN REPLACEMENT AND LABOR WOULD BE IN THE $3000-4500 RANGE AND THE PROBLEM WOULD LIKELY REOCCUR IN THE FUTURE DUE TO FAULTY DESIGN. WORSE, AS MOST PEOPLE IN MY POSITION ARE UNABLE TO PERFORM A REPAIR AT THAT COST, I'VE FOUND NUMEROUS PEOPLE MANIPULATING THEIR STEERING COLUMNS WITH MIXED SUCCESS ULTIMATELY CREATING AN EVEN MORE DANGEROUS POTENTIAL SITUATION. THESE METHODS INCLUDE DRILLING INTO THE STEERING COLUMN AND ADDING GREASES AND LUBRICANTS THAT WERE NOT DESIGNED TO WORK WITH THE VEHICLE. THIS IS A WELL-KNOWN PROBLEM, WITH NO SHORTAGE OF RECORDS AND ACCOUNTS ESTABLISHING THIS ISN'T A "IF IT HAPPENS", BUT WHEN IT HAPPENS. DRIVE A VEHICLE WITH THIS PROBLEM, I DARE YOU, AND TELL ME IT IS NOT A MAJOR SAFETY HAZARD. DISAPPOINTED. I'D APPRECIATE IF BMW WOULD REACH OUT TO ME AND REMEDY THE ISSUE. THERE IS NO REASON THAT A STEERING WHEEL, ONE OF THE MOST BASIC AND NECESSARY SYSTEMS ON A CAR TO MAINTAIN CONTROL, SHOULD HAVE BEEN PERMITTED TO BE DEFECTIVE WITH NO REMEDY AT THE COST OF THE MANUFACTURER. THE LACK OF ACCOUNTABILITY BY BMW AND "DO IT YOURSELF" REMEDIES WILL UNDOUBTEDLY RESULT IN INJURY OR DEATH IF THEY HAVE NOT ALREADY. BMW SHOULD PROVIDE A FIX FOR THOSE Z4S AFFECTED STILL ON THE ROAD BEFORE SOMEONE IS KILLED.
I HAVE A 2003 Z4 WITH 25K MILES. THE STEERING WHEEL STICKS WHILE DRIVING MAKING IT DIFFICULT TO STEER. SPOKE WITH A BMW MECHANIC AND WAS INFORMED THIS IS A KNOWN ISSUE FOR THIS PARTICULAR VEHICLE AND THAT I WILL NEED TO REPLACE THE STEERING COLUMN TO CORRECT THE PROBLEM. THE COST IS $3000. WHY IS THERE NOT A RECALL??
WHEN THE CAR WARMS UP OR HAS BEEN IN THE WARM SUN THE STEERING STICKS. THIS CREATES A DANGEROUS ISSUE WHERE THE STEERING WHEEL WILL POP OVER RATHER THAN SMOOTHLY TURNING. THE PROBLEM CREATES AND OVERSTEERING THAT IS VERY DANGEROUS AT HIGHWAY SPREED AND IN TRAVERSING CORNERS.
AFTER THE CAR WAS PARKED IN THE SUN FOR 4 HOURS, THE CAR WAS HARD TO STEER. THE STEERING WAS STICKY AND MADE IT FEEL UNSAFE TO DRIVE. WE RESEARCHED ON THE INTERNET AND FOUND THIS IS A COMMON PROBLEM FOR THIS YEAR/MODEL BMW Z4.
OVER THE PAST COUPLE YEARS I'VE NOTICED STICKY STEERING BUT AM JUST REPORTING NOW. AT MOST SPEEDS I'VE HAD THE STEERING STICK AND NOT RETURN TO NEUTRAL. OFTEN NEEDING TO REACT OR OVERCORRECT. I'VE NOTICED AN INCREASE IN OCCURRENCE AND SEVERITY THE WARMER THE AMBIENT TEMP IS. WHEN STEERING AROUND A CURVE THE STEERING WHEEL DOESN'T WANT TO COME BACK TO NEUTRAL WITHOUT CORRECTIVE ACTION. THIS AFTERNOON THE AMBIENT TEMP WAS ABOUT 90F AND WITH OCCURED AT EVERY MOVEMENT OF THE STEERING WHEEL. I FEAR THAT THIS IS GOING TO BE THE CAUSE OF AN ACCIDENT AND REALLY TAKES AWAY FROM THE ENJOYMENT OF DRIVING THIS CAR. I'VE READ MANY COMPLAINTS ON THIS SITE AND ALL OVER THE INTERNET DESCRIBING THE SAME ISSUE. OTHER REPORTS I'VE READ STATE THAT THE DEALERS RECOMMENDED REPAIR IS REPLACEMENT OF THE ENTIRE STEERING COLUMN AT A COST OF $3000-$4000.
RIGID STEERING WITH OVER CORRECTION, USUALLY DURING WARM WEATHER. IF GOING AT HIGHWAY/FREEWAY SPEED, EASY TO LOOSE CONTROL AND MAY CAUSE MAJOR INJURY. EXPERIENCED THIS TODAY DRIVING SPEED LIMIT OF 70 MPH AND DECIDED TO SOUND OFF. I HOPE BMW IS NOT WAITING TO ADDRESS THIS PROBLEM UNTIL SOMETHING LIKE THIS HAPPENS. MANY OTHER OWNERS OF SAME MODEL CAR, AND POSSIBLY ALL, ARE HAVING THE SAME PROBLEM BUT NOT COMPLAINING. IT TOOK TODAY'S EXPERIENCE FOR ME TO WRITE.
I JUST PURCHASED THIS 2003 Z4 FROM A DEALER ABOUT A MONTH AGO. WHEN I TEST DROVE IT, IT DROVE FINE AND THE STEERING WAS SMOOTH AS YOU'D EXPECT. IT WAS A LITTLE CHILLY AS IT WAS STILL IN THE MORNING. BY AFTERNOON, DURING MY 6HR DRIVE HOME FROM THE DEALER, IT GOT HOT OUTSIDE, AS IT IS SUMMER AND ALL, AND THE STEERING STARTED TO BECOME VERY JERKY, CAUSING ME TO SWERVE BACK AND FORTH IN THE LANES. IT HAS NOW BECOME A DANGEROUS CAR. THE INITIAL DEALER FROM WHOM I PURCHASED FROM PLAYED DUMB AND SAID THEY WERE UNAWARE OF ANY PROBLEMS. BEFORE BUYING THIS CAR, WHICH HAS 57K MI ON IT, I DID MY RESEARCH. SEEMED LIKE NO MAJOR PROBLEMS WITH IT. NOT UNTIL AFTER I PURCHASED IT, AND SPECIFICALLY SEARCHED 'STEERING PROBLEMS' DID I DISCOVER THIS HAD BEEN A BMW DESIGN FLAW FROM THE BEGINNING AND COUNTLESS PEOPLE HAVE BEEN DEALING WITH THIS ALMOST FROM THE GET GO. NO RECALL HAD BEEN MADE, AND NOW I'M STUCK WITH A DANGEROUS CAR. GOING FORWARD, I HAVE NOTIFIED FRIENDS AND FAMILY, THAT SHOULD I GET KILLED BECAUSE OF THIS DEFECT, START LITIGATION AGAINST BMW, AS THIS IS NOW DOCUMENTED BY MYSELF, AS WELL AS COUNTLESS OTHERS.
ON WARM DAYS THE STEERING AT HIGHER SPEED GETS HARD TO STEER ; TO THE POINT OF BEING UNSTEADY. AT LOWER SPEEDS AND COOLER TEMPS THE HARD STEERING CAN BS HANDLED BUT IS STILL TROUBLESOME. NEED SOMEONE TO TALK TO BMW.
I EXPERIENCE SUDDEN JERKS TO THE LEFT, OT TO THE RIGHT WHEN THE ROAD SURFACE IS SLEGHTINGLY 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 LIGHT. ALSO MAKE A WEIRD SOUND WHEN A TRY TO TURN RIGHT
