2004 BMW Z4 Problems

Twice this month, while operating the vehicle, the power steering completely stopped functioning, causing the vehicle to be almost uncontrollable. No prior warning light. When I purchased the vehicle in 2018, the same problem occurred and the dealer replaced the steering column under warranty. In researching online I find that this is a common problem with this model. I am surprised to find that there is no recall notice for what is a major safety concern.

Power steering wheel went out of power during a trip at about 70mph. Yellow light at the dashboard went ON then so, car became imposible to drive or so.

THEY DO NOT WORK

PASSENGER SEAT OCCUPANCY DETECTION MAT HAS A DEFECTIVE SENSOR. IT INDICATES THAT A CHILD'S WEIGHT IS IN THE SEAT AND THEREFORE WILL NOT PERMIT THE AIR BAG TO DEPLOY. THE FAULT CODE CAN BE RESET, THE LIGHT GOES OUT; STAYS OUT FOR WEEKS AND LIGHTS UP AT RANDOM AGAIN! CLEARING THE FAULT CODE IS BURDENSOME AND DISABLING THE AIR BAG INAPPROPRIATELY IS A SAFETY DEFECT.

REOCCURING ISSUE: -DOOR LOCKS NOT FUNCTIONING BY REMOTE OR CENTRAL BUTTON -WIPERS NOT FUNCTIONING -TRUNK RELEASE NOT FUNCTIONING BY REMOTE OR BUTTON -WINDOWS NOT FUNCTIONING -LIGHTING OF INTERIOR NOT WORKING, TO INCLUDE GAUGE CLUSTER -TOP NOT FUNCTIONING ISSUES INTENSIFY ON DAYS OF LOW/HIGHER TEMPERATURES. SEEMS TO RESET BY DISCONNECTING BATTERY AND RECONNECTING AFTER SEVERAL MINUTES. ISSUES POINTS TO GM5 MODULE BEING FAULTY/FAILING THIS IS NOT DISCOVERED UNTIL YOU START THE CAR, SEEMS TO BE A RANDOM OCCURRENCE, BUT HAPPENS AT LEAST ONCE WEEKLY. SOMETIMES IT IS MULTIPLE TIMES A DAY.

I HAD THIS CAR BUILT AND I AM THE ONLY OWNER AND DRIVER. I HAVE HAD A PERSONAL MECHANIC TAKE METICULOUS CARE OF IT OVER THE YEARS AND THE CAR IS STORED FOR APPROXIMATELY 6 MONTHS/YEAR BECAUSE I DO NOT DRIVE IT IN THE SNOW, AND FRANKLY, HARDLY DRIVE IT EVEN WHEN RAINING. HOWEVER, IT NEVER FAILS THAT EACH YEAR SOME WARNING LIGHT GOES ON FOR NO APPARENT REASON. LAST FALL IT WAS THE ABS LIGHT AND THE BRAKE LIGHT. MY MECHANIC PUT THE CAR ON THE COMPUTER, AND FOUND NO ISSUES. NOW AGAIN, THIS SPRING IT STARTED OUT AS NOT BEING ON, BUT WITHIN 5- 25 MINUTES (VARIES EACH TIME WHEN I START THE CAR UP AND DRIVE) THOSE TWO LIGHTS COME ON. EVERY YEAR THERE SEEMS TO BE NEW LIGHTS THAT COME ON FOR NO APPARENT REASON. I HAVEN'T DRIVEN THE CAR MORE THAN A FEW TIMES BEFORE A LIGHT COMES ON. IT'S COST ME SO MUCH IN DIAGNOSTIC TIME. ALSO ANOTHER PROBLEM IS THAT OFTEN THE RADIO DOESN'T TURN ON. WHEN THIS HAPPENS, THE SCREEN ALSO DOES NOT POP UP. I HAVE TO STOP THE CAR, TURN IT OFF AND THEN RESTART. MOST TIMES THE ELECTRICAL SYSTEM SEEMS TO 'RESTART' ITSELF SO THAT THE RADIO TURNS ON AND THE SCREEN POPS UP. THE ELECTRICAL SYSTEM IN THIS CAR HAS NEVER BEEN RIGHT. *TR

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.

THE STEERING IS THE ONLY PROBLEM BUT YOUR WEB SITE INSISTS ON MY SELECTING AT LEAST 3 AFFECTED PARTS. IN ANY CASE, THE STEERING RECENTLY BECAME JERKY AND NOTCHY WHILE DRIVING. AFTER SEVERAL DAYS OF THIS, I TOOK IT MY LOCAL FOREIGN CAR REPAIR SPECIALIST AND THEY DIAGNOSED A PROBLEM WITH THE ELECTRONIC POWER STEERING. ULTIMATELY, THEY REPLACED THE ENTIRE STEERING COLUMN AT A COST TO ME OF $4100. THIS WAS A VERY UNSAFE CONDITION MAKING MY CONTROL OF STEERING TENUOUS AT BEST AND ONE THAT YOU HAVE RECEIVED NUMEROUS COMPLAINTS ABOUT. *TR

GM5 MODULE FAIL. WHEN THE GM5 MODULE FAULS WINDSHIELD WIPERS WON'T WORK (THIS COULD BE A BIG PROBLEM IF IT RAINS!), INTERIOR LIGHTS WON'T WORK, WINDOWS WON'T GO UP OR DOWN, NO ALARM FUNCTIONS AND OF COURSE NO AUTOMATIC DOOR LOCK CONTROL (DOORS CAN MANUALLY BE LOCKED AND UNLOCKED AS LONG AS THE DOUBLE LOCK IS OPEN.)

I LEFT MY BMW IN THE SUN ALL DAY AND NOW MY LOCKS WONT WORK. MANY RESOURCES LINK THIS PROBLEM TO THE GM5 WHICH CONTROLS THE LIGHTING AND LOCKS. BAD LOCKS CAN BE A SAFETY AND SECURITY ISSUE ON PARKED CARS BUT ALSO FOR MOVING CARS AS CHILDREN MAY OPEN VEHICLE DOORS IN TRAFFIC.

MY BMW 2004 Z4 DOOR ON THE PASSENGER SIDE WOULD NOT OPEN. THE INSIDE AND OUTSIDE HANDLES WOULD NOT OPEN THE DOOR. SHORTLY AFTERWARDS THE DRIVERS SIDE DOOR HANDLE BEGAN TO FAIL INTERMITTENTLY. I WAS LOCKED INSIDE MY VEHICLE WITHOUT THE ABILITY TO GET OUT. *TR

I 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. 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!

I OWN A SUSPECTED Z4 WITH A NHTSA REPORTED "STICKY STEERING" ISSUE I CAN TELL YOU A LITTLE MORE ABOUT IT. THE PROBLEM HAS NOTHING TO DO WITH THE BOOST. WHEN THE CAR GETS HOT (SUMMER HOT) THE STEERING GETS NOTCHY IN THAT WHEN YOU PUT THE CAR IN A SLIGHT TURN, LIKE CHANGING LANES OR GOING AROUND A SLIGHT CORNER, THE STEERING LITERALLY STICKS IN THAT POSITION CAUSING THE DRIVER TO APPLY OPPOSITE PRESSURE TO "BREAK" THE WHEEL LOOSE FROM THE TURN FOLLOWED BY ANOTHER STICK WHEREVER THE WHEEL IS BROUGHT BACK TO. PROBLEM IS THAT IT CAUSES MASSIVE OVER STEERING ISSUES AT HIGH SPEED UNLESS YOU ARE LOOKING FOR IT. EXTREMELY DANGEROUS AT HIGHWAY SPEEDS! BMW KNEW ABOUT IT AND RELEASED MULTIPLE PUMAS (THEIR EQUIVALENT OF A TSB) AND EVEN REDESIGNED THE SUSPECT COLUMN, BUT REFUSED TO REPLACE THE OLDER ONES OUT OF WARRANTY. THESE ARE $3000 BEFORE LABOR AND BMW HAS FLAT OUT TOLD ME THAT THEY WON'T COVER A SINGLE DOLLAR OF IT. I GUESS WE WILL SEE NHTSA FORCES THEIR HAND! I AM SCARED TO DEATH TO DRIVE THE VEHICLE I HAD TO JERK TO OUT OF ANOTHER LANE SEVERAL TIMES AND YOU MUST WORK EXTREMELY HARD TO KEEP IT STRAIGHT. PLEASE DO SOMETHING BEFORE SOMEONE GETS HURT. *TR

PASSENGER'S AIRBAG INDICATION LIGHT IS MALFUNCTIONED. THE INDICATION LIGHT OF PASSENGER'S AIRBAG SHOWS ALWAYS OFF. THEREFORE IT CAN'T TELL THE AIRBAG IS ON OR OFF. *TR

WE PURCHASED THE VEHICLE USED LATE SUMMER 2013. UPON HAVING THE VEHICLE INSPECTED WE DISCOVERED THAT BOTH REAR COIL SPRINGS WERE BROKEN. WE WERE TOLD BY MULTIPLE RESOURCES THAT THIS IS A COMMON PROBLEM WITH BMW. WE REPLACED THE SPRINGS. I WANT TO KNOW WHY THIS IS NOT A RECALL. OTHER BRAND/MODELS WITH CRACKED/BROKEN REAR COIL SPRINGS HAVE HAD RECALLS. THIS IS A SAFETY ISSUE. HIGH SPEED CORNERING COULD CAUSE SPRINGS TO SEPARATE FROM VEHICLE. *TR

TL* THE CONTACT OWNS A 2004 BMW Z4. THE CONTACT STATED THAT UPON ENTERING HER VEHICLE AND STARTING IT, SHE WAS UNABLE TO SHIFT THE VEHICLE INTO ANY GEAR. THE VEHICLE WAS INSPECTED BY A DEALER WHO INFORMED THE CONTACT THAT SHE WOULD NEED TO REPLACE THE AUTOMATIC MANUAL TRANSMISSION. THE VEHICLE WAS REPAIRED YET THE FAILURE RECURRED WITHIN 32,000 MILES. THE MANUFACTURER WAS CONTACTED AND INFORMED THE CONTACT THAT THEY WERE UNABLE TO ASSIST WITH REPAIRS. THE FAILURE MILEAGE WAS APPROXIMATELY 41,900.

STEERING HAS A "NOTCHED" OR "STICKY" FEEL TO IT WHEN TRAVELING ON HIGHWAYS AT SPEEDS AROUND 50MPH AND HIGHER. WHEN THE NEED TO TURN ARISES AND THE STEERING WHEEL "STICKS" IN THE 'NOTCH", IT REQUIRES EXTRA EFFORT TO GET THE WHEEL OUT OF THE NOTCH, CAUSING "OVER STEER" WITH DIFFICULT RECOVERY. I WON'T LET MY WIFE DRIVE THE Z-4 AS I FEEL THIS IS A DANGEROUS CHARACTERISTIC THAT COULD RESULT IN AN ACCIDENT. MY DEALER WAS NOTIFIED OF THE SITUATION BUT WAS "UNABLE TO DUPLICATE" THE FAULT; (PRIOR TO MY WARRANTY RUNNING OUT). ON THE FOLLOWING SERVICE, WITH MY RENEWED COMPLAINT, THE DEALER WAS ABLE TO DUPLICATE AND IDENTIFY THE PROBLEM. MY BMW WARRANTY WAS EXPIRED, BUT I HAD PURCHASED AN "EXTENDED WARRANTY", HOWEVER THE "STEERING" PROBLEM WAS NOT COVERED UNDER THE NEW WARRANTY. THE COST FOR REPAIR WAS IN EXCESS OF $3000.00! I HAVE PARKED THE CAR EXCEPT FOR LOCAL SLOW SPEED, COOL DAY RIDES. I UNDERSTAND THAT THE NHTSA HAS LOOKED INTO THE PROBLEM. I HAVE NOT HEARD ANYTHING FROM MY BMW DEALER YET. ??? A COMPUTERIZED "BRAKE SENSOR" LIGHT HAS BEEN ON FOR MANY YEARS AND HAS BEEN UNABLE TO BE REMEDIED. THE DEALER CHECKED THE BRAKES AND THEY ARE FINE, JUST CAN'T GET THE "SENSOR LIGHT" TO STAY OUT. *TR
