2009 BMW Z4 Complaints

ALUMINUM WHEEL (STYLE 296) CRACK ON THE INSIDE BEAD. CAR HAS 22,000 MILES ON 1/23/14 AND 3 WHEELS CURRENTLY HAVE CRACKS. THE CRACKS PREVENT THE TIRES FROM MAINTAINING AIR PRESSURE AND LOWERS THE STRUCTURAL INTEGRITY OF THE RIM, CAUSING A SAFETY HAZARD. BMW IS ONLY OFFERING TO REPAIR ONE WHEEL UNDER WARRANTY BECAUSE THE RUNOUT ON THE OTHER 2 WHEELS WAS 0.059" WHICH THEY ARE CLAIMING INDICATES THAT THE WHEELS ARE DAMAGED DUE TO A ROAD HAZARD BUT OFFERED NO VISUAL EVIDENCE OF DAMAGE. ONLINE RESEARCH INDICATES THERE IS A HIGH RATE OF FAILURE OF THE 296 STYLE WHEEL AND CONTRIBUTING FACTORS INCLUDE THE DESIGN OF THE 19" WHEEL, THE USE OF 30 SERIES (REAR) OR 35 SERIES (FRONT) RUN-FLAT-TIRES AND THE NEGATIVE CAMBER. THE NEGATIVE CAMBER PUTS THE MAJORITY OF THE FORCES AND LOAD FROM THE ROAD ONTO THE INSIDE BEAD OF THE RIM. THE RUN-FLAT-TIRES HAVE EXTREMELY STIFF AND SHORT SIDEWALLS TO ALLOW THE TIRES TO BE DRIVEN WITH NO AIR, WHICH TRANSMITS THE FORCES FROM THE ROAD DIRECTLY TO THE RIM WITHOUT THE NORMAL CUSHION OF A STANDARD TIRE. THE DESIGN OF THE RIM DOES NOT ADD ADDITIONAL STRENGTH TO THE INSIDE BEAD TO MAKE UP FOR THE ADDITIONAL LOADS CAUSED BY THE CAMBER AND RUN-FLAT-TIRES. *TR

I HAD A SLOW TIRE LEAK SO I TOOK MY CAR IN TO GET CHECKED. TURNS OUT MY 2 REAR WHEELS ARE CRACKED.THIS IS COMMON PROBLEM FOR OWNERS WITH THE 296 WHEEL ON THE Z4. *TR

MY REAR RIMS HAVE DEVELOPED CRACKS WHILE DRIVING RESULTING IN QUICK LOSS OF TIRE PRESSURE AND IN SOME CASES DESTROYING TIRE. THIS HAS HAPPENED TO BOTH THE LEFT AND RIGHT SIDES, HOWEVER THUS FAR HAS ALWAYS BEEN ISOLATED TO THE REAR (MODEL 296 19") RIMS. IN THE 16 MONTHS I HAVE OWNED THIS VEHICLE, THIS HAS HAPPENED SEVERAL TIMES INCLUDING ON 5/11/2012, 9/9/12, 4/12/13 AND 5/23/13. EACH TIME I HAVE PURCHASED A NEW RIM OR HAD THE EXISTING RIM REPAIRED AT THE DISCRETION OF THE DEALER. IN NONE OF THESE CASES HAS THERE BEEN ANY IMPACT OR DRIVING CONDITION THAT EXPLAINS THE FAILURE. *TR

I HAD TWO OF THESE RIMS BEND AND CRACK ( MODEL 296) I HAD THE RIM AND TIRE WARRANTY THAT I PAID EXTRA FOR AND BMW COVERED A REPLACEMENT FOR ONE AND PAID TO HAVE THE OTHER STRAIGHTENED. *TR

BOTH REAR WHEELS DEVELOPED CRACKS. THESE WERE 19 INCH BMW STYLE 296 WHEELS WITH RUN-FLAT TIRES. *TR

I AM LEASING A 2009 Z4 BMW, THE ENGINE CAR STALL WHILE DRIVING THIS HAPPENED TWICE IN A PERIOD OF 2 WEEKS, I ALMOST HAVE A CAR CRASH BEHIND IN BOTH OPPORTUNITIES, THANKS THAT THE TRAFFIC WAS VERY SLOW, THE SECOND TIME I HAVE TO GO OUT THE ROAD. I BROUGHT THE CAR THE FOR SERVICE, THEY WERE ABLE TO REPRODUCE THE FAILURE, AFTER ONE WEEK AT THE SHOP THEY SAY IT WAS A COMPUTER FAILURE, THEY REPLACE THE COMPUTER HOWEVER AFTER 2 WEEKS THE CAR STILL IN THE SHOP I HAVE CALL SEVERAL TIMES TO CUSTOMER SERVICE AND THE SERVICE SHOP BUT I DON'T GET ANY SPECIFIC ANSWER OF WHAT IS GOING ON, I FEEL I DON'T HAVE ANY RIGHTS AS A CONSUMER AND IN THE OTHER HAND I AM CONCERNED FOR MY SAFETY SINCE THEY SAID THEY DON'T GUARANTEE THIS WON'T HAVEN AGAIN EVEN IF THE CAR IS FIXED. DO I HAVE ANY RIGHTS AS A CONSUMER OR I HAVE TO ACCEPT THIS SITUATION. *TR
