The electronic steering has failed several times while driving. This makes it very difficult to maintain a lane and avoid other vehicles. This problem continues intermittently. Thousands of Z4 owners have reported the same issue in online forums.
In hot weather, the steering binds, making keeping the car in the correct lane extremely difficult. The car will dart from one side to the other. The car will be nearly impossible to keep in the correct lane.
I have just found out that my 2006 BMW Z4 Convertible has serious wiring issues. The wires for example on my front headlights the insulation is falling off the and leaving bare wires. I am very concerned this could be a fire safety issue that could result in bare electrical wires shorting together and starting a car fire. My research shows that many people who have 2006 BMW Z4 Convertibles are having this same issue. This seems to be a real issue with BMW using cheap wiring harnesses material and over time due heat and cooling is cause the insulation to fail and resulting in this issue.
When the car gets hot (parked in the sun) the steering becomes knotchy or sticky and the car becomes difficult to control. No problems whatsoever when the car is cool or on a cooler day. This problem has been witnessed by a BMW technician and there are no warning lights. This appears to be a fairly common issues with these cars.

The Steering wheel gets Hard, looks like power steering gets disabled automatically while driving, making it almost impossible to steer. This has started to happen after hot weather had started few months back. I have tried to reproduce this issue several times, but it happens randomly and Not all the time. I don't drive the car much. But this is definitely a serious issue, I checked the BMW community and a lot of people are facing this issue. Not Sure how many have filed a complaint here. But this definitely should be addressed by BMW as this is not just one person facing this issue, there are hundreds and thousands of them. Level of severity is high, as someone who might have not faced this issue yet might suddenly face it on the highway could result in an extremely fatal accident. Havent reported to BMW yet, But found this issue is being faced by alot of people I thought to file my complaint here. I will soon get it repaired or replaced. There were no Warning lamps or messages prior to this. It started happening in September 2021.
When the outside temperatures are warmer (mid 80's and above) the steering wheel will stick in the center position and require it to be jerked a bit to keep control. This occurs at all speeds, but does not seem to be the case when stopped. since it requires the steering wheel to be jerked to correct, it can cause the car to swerve. I have had the car for several years began noticing the issue once the weather got warmer. The date entered below is today's date, but I have had the issue for perhaps 5 years.
During warm weather the steering will momentary stick while driving which requires additional force to overcome. This happens at all speeds but is more noticeable at highway speeds while trying to maintain vehicle in driving lane. There are numerous complaints of this on the NHTSA site. I have written to BMW North America about this safety problem and mentioned the multitude of similar complaints but they refuse to address the problem and suggest I purchase a new steering column at $2500+!
THE CONVERTIBLE TOP ON THE 2006 Z4 BMW HAS A MECHANISM THAT RAISES AND LOWERS THAT FAILS. IT'S LOCATION IS SUCH THAT IT IS EXPOSED TO THE ELEMENTS. WHEN I BOUGHT MY CAR (USED)I WENT TO A BMW MECHANIC THAT TOLD ME THAT IF I DID HAVE HIM FIX IT IT WOULD HAPPEN AGAIN. TALKING TO OTHER BMW MECHANICS I GOT THE SAME INFO.
VEHICLE STEERING BECOMES "STICKY" AFTER VEHICLE HAS BEEN EXPOSED TO WARM TEMPERATURES. THIS CAUSES THE STEERING TO CENTER AND REQUIRE GREATER THAN USUAL FORCE TO OFF CENTER THE WHEEL, CAUSING THE CAR TO BE DIFFICULT TO CONTROL ESPECIALLY AT HIGHWAY SPEEDS.
WENT TO CHANGE MY HEADLIGHT BULB AND NOTICES ALL OF THE WIRES WERE BARE. THE SHEATHING AROUND THE WIRES HAVE ALL CORRODED. THIS IS FOR THE COMPLETE HEADLIGHT ASSEMBLY. EVERY SINGLE WIRE HAS CORRODED. SEEMS LIKE A FIRE HAZARD.
ABOUT 9 YEARS (2015) AFTER PURCHASING VEHICLE THE AIRBAG WARNING LIGHT BEGAN ILLUMINATING CONSTANTLY. THE VEHICLE WAS PURCHASED NEW AND HAD APPROXIMATELY 55K MILES WHEN ISSUE BEGAN. VEHICLE HAS NEVER BEEN IN A MINOR OR MAJOR ACCIDENT. VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, BUT DIAGNOSIS COULD NOT BE DETERMINED. CONTACTED BMW ABOUT ISSUE, BUT WAS TOLD MY VEHICLE WAS NOT COVERED UNDER ANY OF THE AIRBAG RECALLS THEY'VE INITIATED. NO ACTION WAS TAKEN BY ME TO DETERMINE ROOT CAUSE AND CONTINUED TO UTILIZE VEHICLE WITH AIR BAG LIGHT ALWAYS ILLUMINATED. IN FEBRUARY 2018, RECEIVED A LETTER FROM BMW REGARDING WARRANTY EXTENSION TO 15 YEARS FOR FRONT PASSENGER SEAT OCCUPANCY MAT (OC3) FOR AIR BAG SYSTEM. BELIEVING AIRBAG ISSUE WAS DUE TO OC3 MAT, BROUGHT MY VEHICLE TO LOCAL BMW DEALER TO GET REPAIR. BMW DIAGNOSED THE ISSUE AS A "RESTRAINT PASS LOWER BELT UNIT FAULTING" AND NOT OC3 MAT. HAD REPAIR PERFORMED SUCCESSFULLY.
THE INSULATED WIRING INSIDE THE HEADLIGHT HOUSING HAS HARDENED AND THE INSULATION HAD CRACKED AND FALLEN OFF. THIS ALLOWS THE WIRES TO SHORT AND CAUSES UNEXPECTED FAILURE OF THE HEADLIGHTS, PARKING LIGHTS, TURN SIGNALS AND OTHER ITEMS INSIDE THE HEADLIGHT HOUSING. THE LIGHTS FAILED UNEXPECTEDLY AND INTERMITTENTLY.
VERY STICKY STEERING, DANGEROUS IN HOT WEATHER, THIS HAPPENS AT ALL SPEEDS. IT SOMETIMES REQUIRES SIGNIFICANT EFFORT TO CORRECT IT. THIS IS A SERIOUS SAFETY ISSUE.
MY BATTERY IS IN GOOD CONDITION BUT I CAN'T START THE ENGINE.-700KM OIL SERVICE WARNING LIGHT DISPLAY ON MY DASH.FUEL PUMP IS WORKING.THEM OPEN THE KEY LIKE THAT SOUND GAP GAP IS COME OUT...PLS HELP ME...
STEERING APPEARS TO BE STICKING OR STAYING AT A CERTAIN POINT IN THE STEERING RADIUS. I ALMOST VEERED INTO ONCOMING INTERSTATE TRAFFIC. I COMPENSATED IMMEDIATELY, BUT IT RELEASED ITS "STICK" AND TURN TO MUCH AND ALMOST VEERED INTO TRAFFIC I WAS IN. VERY SCARY, VERY DANGEROUS. THERE WAS A POSSIBILITY OF MUCH INJURY OR DEATH BECAUSE OF THIS ISSUE. BAD
RECURRING PROBLEM WITH STEERING INPUT EFFORT WHEN DRIVING ON HIGHWAYS. THE STEERING STICKS WHEN IN THE CENTER POSITION. RESISTANCE IS FELT AND IS DIFFICULT TO RETURN BACK TO THE CENTER POSITION. STICKING PROBLEM SEEMS WORSE AT HIGHER SPEEDS AND WITH WARM OUTSIDE TEMPERATURE ABOVE 80 DEGREES. THE FASTER THE SPEED, THE MORE EFFORT NEEDED TO OVERCOME THE DETENT RESISTANCE, TO THE POINT THAT IT BECOMES EASY TO OVERSTEER THE CAR. THIS CAN BE REAL SCARY DURING AVOIDANCE MANEUVERS AND QUICK LANE CHANGES.
THE CONVERTIBLE TOP FAILED 2011/30229 MILES, STILL UNDER CPO WARRANTY. THE DEALERSHIP ONLY TOPPED OFF THE HYDRAULIC FLUID AND CLAIMED NO LEAK FOUND. IT FAILED AGAIN 2014/45809 MILES. THIS TIME SEALS WERE REPLACED AND HYDRAULIC LINES. GOODWILL REPAIR WITH 50% OUT OF POCKET. IT FAILED AGAIN EARLIER THIS YEAR 2018/62112 MILES. THIS TIME I WAS QUOTED $2,938 TO $3,658. I HAD IT DIAGNOSED IN MAY AND WAS WAITING FOR AN ANSWER OF THE SERVICE MANAGER ABOUT BMW ASSISTING WITH THE REPAIR AND HAD NOT HEARD BACK. I INQUIRED AGAIN TWO DAYS AGO AND GOT A REPLY THAT BMW WOULD NOT PICK UP ANY OF THE REPAIR COST. IT APPEARS THAT IT WAS A SLOWLY DEVELOPING DEFECT. WHERE WOULD HAVE THE FLUID HAVE GONE AT THE FIRST REPAIR? ALSO DOING SOME RESEARCH TURNED UP A LOT OF THE SAME TROUBLE FOR OTHER OWNERS. APPARENTLY IT IS A DESIGN FLAW. WATER NOT DRAINING BECAUSE OF CLOGGING AND CONSEQUENTLY CAUSING DAMAGE TO THE HYDRAULIC SYSTEM.
THE VEHICLE WAS PARKED IN A GARAGE AND SET ON FIRE, RESULTING IN A HOUSE BEING BURNED DOWN AND THE FATALITY OF MY FATHER. THE FIRE MARSHAL'S REPORT WAS INCONCLUSIVE AS TO HOW THE FIRE STARTED.
STEERING IS EXTREMELY NOTCHY AND UNPREDICTABLE, ESPECIALLY ON HOT DAYS. WHEN IN MOTION, THE STEERING WHEEL REQUIRES FORCE TO TURN, AND SOMETIMES WILL TURN SLIGHTLY WITHOUT DRIVER INPUT. IT APPEARS THAT THE POWER ASSIST STEERING IS ACTUATING WHEN IT SHOULD NOT BE, CAUSING EITHER RESISTANCE TO STEERING INPUTS, OR APPLYING FORCE WHEN NO STEERING INPUT HAS BEEN APPLIED. WHEN THE ENGINE IS NOT RUNNING, OR AT VERY SLOW SPEEDS, NOISE CAN BE HEARD FROM THE POWER ASSIST MOTOR. IT ACTUATES WHEN NO STEERING INPUTS ARE BEING APPLIED. WHEN STEERING INPUTS ARE APPLIED, TOO MUCH RESISTANCE CAN BE FELT AND THE MOTOR MAKES ADDITIONAL NOISES. I PURCHASED THE CAR IN FEBRUARY OF 2016, AND THIS HAS BEEN HAPPENING SINCE APPROXIMATELY SPRING OF 2016. IT HAS BEEN GETTING PROGRESSIVELY WORSE.
DURING WEATHER ABOVE 80 DEGREES, THE STEERING BECOMES "TWITCHY" OR "NOTCHY," NO LONGER SMOOTH, BUT REQUIRING ADDITIONAL EFFORT TO TURN THE STEERING WHEEL, AT WHICH POINT, THE TIRES MOVE MORE THAN NEEDED, REQUIRING A STEERING ADJUSTMENT THE OPPOSITE DIRECTION. AT THE SAME TIME, THE CAR DOES NOT HOLD A "LINE" AS WELL, REQUIRING A SERIES OF SMALL LEFT AND RIGHT STEERING CORRECTIONS.
ON WARM DAYS THE STEERING ON MY 2006 BMW Z4 BECOMES UNRESPONSIVE AND UNPREDICTABLE. ON HOT DAYS IT IS DOWNRIGHT DANGEROUS. I HAVE READ IN MANY PLACES THAT THIS IS DUE TO A DESIGN DEFECT IN THE STEERING COLUMN. ONE SOURCE WHO IS AN ASE-CERTIFIED MASTER TECHNICIAN SAYS THAT THE "BMW Z4 STICKY STEERING IS RELATED TO A MANUFACTURING DEFECT, THAT HAS BEEN RECTIFIED AS OF 2007 AND UP. THERE IS A BEARING LOCATED IN THE MIDDLE OF THE STEERING COLUMN THAT IS NOT SEALED. WITH TIME AND WHEN HOT, THE LUBRICANT GETS DRY AND GUMS UP. TO MAKE MATTERS WORSE, THERE IS NOT A RACE FOR THE BEARING TO RIDE IN ' THE INNER RACE IS ACTUALLY THE STEERING SHAFT ITSELF, WHICH IS A POOR DESIGN". MY VEHICLE WAS BUILT IN 2006 AND HAS ONLY 54,000 MILES ON IT. BMW APPARENTLY WAS AWARE OF THIS PROBLEM AND CORRECTED IT THE FOLLOWING MODEL YEAR. THERE ARE MANY COMPLAINTS ON THE NHTSA WEBSITE ABOUT THE SAME PROBLEM, WHICH COULD GET WORSE OVER TIME. BMW SHOULD ISSUE A RECALL BEFORE SOMEONE GETS SERIOUSLY HURT.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
