2006 BMW Z4 Problems & Complaints

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.

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.

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.

TL* THE CONTACT OWNS A 2006 BMW Z4. THE CONTACT STATED THAT THE AIR BAG WARNING INDICATOR REMAINED ILLUMINATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOISED THAT THE OCCUPANT PROTECTION MAT WAS DEFECTIVE AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REAPIRED. THE VEHICLE WAS PREVIOUSLY REPAIRED UNDER NHTSA CAMPAIGN NUMBER: 13V564000 (AIR BAGS). THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 65,000.

PASSENGER SEAT OCCUPANCY SENSOR FAILURE. 2006 BMW Z4. SENSOR MAT FAILED WITHOUT STRESS ON THE SEAT. IT APPEARS TO FAIL OVER TIME. PASSENGER AIRBAG DEFAULTS TO OFF CONDITION. IF AN ACCIDENT OCCURS WITH A PASSENGER IN THE CAR THE PASSENGER AIRBAG WILL NOT DEPLOY. 2005 AND EARLIER MODELS HAVE BEEN OFFERED A 10 YEAR EXTENDED WARRANTY TO COVER THIS PROBLEM WITH THE SAME PART. NO ADDITIONAL WARRANTY HAS BEEN OFFERED FOR 2006 MODELS.

FRONT PASSENGER AIR BAG SENSOR WARNING LIGHT ON - PASSENGER AIR BAG WILL NOT FUNCTION IN EVENT OF COLLISION. PASSENGER AIR BAG SENSOR WARNING CODE CAN NOT BE RESET. THE CAR AIR BAG SYSTEM HAS NEVER BEEN ACTIVATED BY COLLISION. THE FRONT PASSENGER AIR BAG WARNING LIGHT FIRST APPEARED WHEN STARTING THE CAR IN GARAGE AND IS NOT ASSOCIATED WITH ANY COLLISION EVENTS. IT APPEARS TO BE LINKED TO SIMILARLY REPORTED BMW MODELS RECALLS INVOLVING THE FRONT PASSENGER SEAT AIR BAG SENSOR MAT FAILURES, WHICH REQUIRES SEAT AIR BAG SENSOR MAT REPLACEMENT. THE PROBLEM IS IT IS NOT CLEAR IF CURRENT AIR BAG SENSOR MAT RECALLS INCLUDE AND COVER THE BMW 2006 Z4 PASSENGER AIR BAG SEAT SENSOR MAT REPLACEMENT. THE CAR WAS PURCHASED FROM BMW DEALER AS A PRE-OWNED CERTIFIED CAR UNDER FULL WARRANTY. THE DEALER WOULD NOT ADDRESS REPAIRS UNDER THE CURRENT RECALLS.NEED YOUR HELP, THERE ARE NOT THAT MANY Z4 ON THE ROAD AND THE NUMBER OF OWNER REPORTED FAILURES IS LIKELY TO BE A SMALL NUMBER BUT THIS DOES NOT DIMINISH THE FACT THAT THE SEAT SENSOR MAT IN A Z4 ARE THE SAME EQUIPMENT BEING RECALLED FOR OTHER BMW MODELS. PLEASE EXTEND THE FRONT PASSENGER SEAT AIR BAG SENSOR MAT RECALL TO INCLUDE THE 2006 Z4 MODELS. THANK YOU, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

PURCHASE THE LISTED VEHICLE IN POMPANO BEACH, FL WHICH IS OVER 250 MILES FROM OUR HOME. TEST DROVE AND EVERYTHING APPEARED TO BE WORKING IN A NORMAL MANNER. ABOUT 50 MILES FROM HOME, THE PASSENGER AIR BAG LIGHT CAME ON LOCATED ON THE CONSOLE, AS WELL AS ON THE DASH. THE DEALER WHERE THE PURCHASE WAS MADE WOULD NOT DO ANYTHING ABOUT IT UNLESS WE BROUGHT THE VEHICLE BACK TO THEM OR ONE OF THEIR OTHER FACILITIES, THE NEAREST ONE OVER 100 MILES AWAY. WE WERE TOLD THAT THE AIR BAGS WOULD STILL DEPLOY PROPERLY EVEN WITH THE AIR BAG LIGHT BEING ON. ON 06/18/14, I WENT ONLINE TO SEE HOW THE AIR BAG SEAT SENSOR COULD BE REPLACED. LO AND BEHOLD, I FOUND A LETTER FROM NHTSA STATING THAT THE SEAT SENSORS COULD CRACK AND AFFECT THE PROPER AIR BAG DEPLOYMENT IN CASE OF AN ACCIDENT. MY VEHICLE YEAR AND MODEL WAS LISTED AS AN AFFECTED MODEL. WE VISITED THE BMW DEALERSHIP IN OCALA, FL TODAY AND SHOWED THE NHTSA LETTER TO THE SERVICE ADVISOR AND HE STATED HE HAD NO HISTORY OF A RECALL. BMW WANTS TO USE THE VIN # AS A DETERMINING FACTOR. ALTHOUGH THE NHTSA LETTER DOES NOT SAY A WORD ABOUT VIN'S, BUT RATHER, JUST YEAR, MAKE AND MODEL. IT ALSO CLEARLY INDICATES THAT ALL SEAT SENSORS COULD CRACK AFFECTING THE SAFETY OF THE AIR BAG DEPLOYMENT IN CASE OF AN ACCIDENT, THIS INDICATES TO ME THAT THIS COULD HAPPEN, NOT THAT IT HAS HAPPENED. BMW DOES NOT WANT TO DO A THING ABOUT IT UNLESS I PAY THEM $159.95 FOR A DIAGNOSTIC TEST AND I CONSIDER THIS AS BEING TAKEN ADVANTAGE OF AS A RESULT OF BEING A 79 YEAR OLD SENIOR CITIZEN. CAN YOU HELP ME WITH MY DILEMMA? FOR THE RECORD, THE VEHICLE WAS OFFERED FOR SALE BY LEXUS OF CLEARWATER ON 02/06/14. ASSUMING IT DID NOT SELL WITH THIS DEALER, THEN MERCEDES OF POMPANO ACQUIRED THE VEHICLE AND OFFERED IT FOR SALE ON 03/06/14. I MADE THE PURCHASE ON 04/02/14. ALL OF THESE DATES ARE CLOSELY RELATED TO THE MIDDLE OF THIS RECALL TAKING PLACE. *TR

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.

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.

CHANGING A HEADLIGHT BULB ON DRIVERS SIDE NOTICED FLAKING INSULATION ON WIRING HARNESS. IN THE PROCESS OF REMOVING HEADLAMP, INSULATION ON ALL THE WIRING ALMOST COMPLETELY DISINTEGRATED. I CAN ONLY ASSUME THAT THIS SAME CONDITION EXISTS ON THE PASSENGER SIDE. THIS WOULD SEEM TO PRESENT A FIRE HAZARD AT WORST AND A LOSS OF LIGHTING AT THE LEAST. I UNDERSTAND FROM READING VARIOUS FORUMS THAT THIS IS A PROBLEM ACROSS MANY BMW MODELS. FURTHER, IT APPEARS THAT BMW USED A SOY BASED INSULATION PRODUCT ON THESE WIRES. ISN'T SOY BIODEGRADABLE? WHY WOULD THIS BE USED IN A WIRING HARNESS.

ON MY 2006 BMW Z4 3.0I, WHILE REPLACING A BLOWN HEADLIGHT BULB I DISCOVERED THAT THE INSULATION ON THE LOW BEAM HEADLIGHT WIRING WAS CRUMBLING OFF AND IN PARTS HAD BARE COPPER WIRE SHOWING. AS THIS IS THE MAIN HEADLIGHT WIRING AND BOTH THE + AND - WIRES WERE SHOWING BARE COPPER A SHORT CIRCUIT AND OR FIRE COULD BE POSSIBLE. THIS WIRING IS WITHIN THE HEADLIGHT HOUSING IT'S SELF. UPON DOING RESEARCH ONLINE I AM NOT THE ONLY PERSON AFFECTED. I REPORTED THIS ISSUE TO MY LOCAL BMW DEALER WHO SAID THERE WERE NO RECALLS AT THIS TIME AND I COULD CALL BMW NA. I CALLED BMW NA WHO REPEATED THAT THERE WAS NO RECALL AND SAID THEY WOULD MAKE A NOTE OF IT BUT OFFERED NO OTHER HELP. *JS

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.

THE BATTERY ON THE VEHICLE WAS DEAD AND REPLACED. AFTER THE BATTERY WAS REPLACED, THE VEHICLE IS IN "TRANSPORTATION MODE". UNDER THIS MODE, THE AC, FAN AND REAR DEFROSTER DO NOT WORK. THE VEHICLE NEED TO BE RETURNED TO THE DEALER TO REINITIALIZE THE SOFTWARE TO REMOVE THE TRANSPORTATION MODE. *TR

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.

THE PASSENGER SEAT AIRBAG SEAT MAT SENSOR SHORTED. *TR

REFERENCE DEFECT INVESTIGATION EA08001, NHTSA CAMPAIGN ID NUMBER: 08V384000; PASSENGER SEAT OCCUPANCY PAD CRACKED CAUSING AIR BAG LIGHT THAT REMAINS ON. UNCLEAR WHICH (IF ANY) AIRBAGS ARE OPERATIVE. REFERENCE CAMPAIGN FOR THE SAME ISSUE DID NOT INCLUDE THIS YEAR VEHICLE. BMW PROVIDED FOR EXTENDED 10 YEAR WARRANTY ON 2004-2005 Z4 VEHICLES AS PART OF THE RESOLUTION TO REFERENCE CAMPAIGN. *TR

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.

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...

MY CAR HAD APPROXIMATELY 65K MILES ON IT WHEN THE LIGHT ON THE DASHBOARD INDICATED AN ISSUE. IT WAS MANUFACTURED IN 08/06. READING FROM THE COMPUTER INDICATED A PASSENGER OCCUPANCY MAT FAILURE. BMW EXTENDED THE WARRANTY FOR 10 YEARS THROUGH MODEL YEAR 05 BUT WON'T DO ANYTHING FOR 2006. I CALLED BMW USA AND ESCALATED IT. THEY CALLED ME BACK AND STATED IT WILL NOT BE COVERED. I AM CONCERNED THAT THIS MAY PREVENT THE AIRBAG FROM OPERATING IN CASE OF A COLLISION FOR THE PASSENGER. THERE ARE MANY COMPLAINTS ABOUT THE 2006 MODEL OCCUPANCY MAT WITH THIS MY AND I THINK BMW SHOULD BE FORCED TO COVER THIS SAFETY HAZARD. THE CAR WAS PURCHASED FROM BMW DEALER AS A PRE-OWNED CERTIFIED CAR UNDER FULL WARRANTY. THE DEALER WOULD NOT ADDRESS REPAIRS UNDER THE CURRENT RECALLS. THIS SHOULD BE COVERED THE SAME WAY AS PREVIOUS MODEL YEAR Z4 VEHICLES. ACCORDING TO RECALL 13V-564 THIS SHOULD BE COVERED BUT BMW SAYS NO!

SPRING IN STEERING WHEEL THAT IS PART OF AIR BAG CAUSES WARNING LIGHT. LESS THAN 50 K MILES ELECTRICAL ISSUES. HAVE HAD 2 REPLACE THE BATTERIES TWICE IN 5 YEARS. HAVING TO REPLACE THE BLOWER MOTOR TWICE, AND THE CONSOLE CONTROLS FOR AIR CONDITIONER AND HEATER. LASTLY, WHEN THE ENGINE IS WARM AND YOU COME TO A STOP LIGHT, THE ENGINE SURGES DRASTICALLY. BMW SERVICE CLAIMS THAT IT IS NORMAL. AND

DRIVER'S SIDE MIRROR FELL OF MOUNT. THERE WAS NO ACCIDENT OR DAMAGE TO THE MIRROR MOUNT. I HAVE CHECKED BMW WEBSITE AND FOUND THAT IT IS DUE TO POOR GLUE/GLUING. THIS DEFECT CAN CAUSE ACCIDENTS DUE TO FLYING GLASS, AND IMPAIR DRIVER'S REAR VIEW. *TR

TL* THE CONTACT OWNS A 2006 BMW Z4. THE CONTACT STATED THAT THE VEHICLE SUDDENLY ACCELERATED INDEPENDENTLY. THE FAILURE WAS EXPERIENCED SEVERAL TIMES WHILE DRIVING AT VARIOUS SPEEDS. THE CONTACT BELIEVED THAT THE CRUISE CONTROL CAUSED THE VEHICLE TO SUDDENLY ACCELERATE BECAUSE ONCE THE VEHICLE DECELERATED TO NORMAL SPEED, THE VEHICLE CONTINUED TO ACCELERATE GRADUALLY AT A HIGHER SPEED. THE VEHICLE WAS TAKEN TO THE DEALER WHERE A DIAGNOSTIC WAS PERFORMED THAT WAS UNABLE TO LOCATE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE VEHICLE WAS LEFT WITH THE DEALER FOR FURTHER INSPECTION. THE FAILURE MILEAGE WAS 44,000 AND THE CURRENT MILEAGE WAS 54,000.

THE STEERING WHEEL INTERMITTENTLY LOCKS UP AT HIGHER SPEEDS (50-70 MPH). USUALLY THE ISSUE HAPPENS WHEN THE TEMPERATURE IS ABOVE 85 DEGREES. *TR

PASSENGER AIRBAG DEACTIVATION LIGHT ALWAYS ON (SINCE 20,000 MILES APPROX) TOGETHER WITH DASHBOARD AIRBAG WARNING LIGHT. GARAGE DIAGNOSED FAULTY PASSENGER SEAT PRESSURE MAT AND ADVISED PASSENGER AIRBAG WOULD NOT DEPLOY IN THE EVENT OF AN ACCIDENT. BMW NORWELL MA, WHO SOLD THE CAR TO US, STATED NO RECALL ON 2006 MODEL (CONVERSATION WITH THEIR SERVICE DEPT. OF 10/21/2011) ALTHOUGH ALL Z4S UP TO 2005 WERE RECALLED FOR MAT REPLACEMENT. BMW WERE CLEARLY STILL FITTING DEFECTIVE PRESSURE MATS IN THE 2006 MODELS AND WOULD APPEAR TO BE NOT ONLY JEOPARDIZING OUR SAFETY BUT ALSO AVOIDING THEIR RESPONSIBILITIES. *TR

TL*THE CONTACT OWNS A 2006 BMW ROADSTER Z4. THE CONTACT STATED WHILE DRIVING 40 TO 70 MPH THE STEERING WHEEL PULLED TO THE RIGHT WHICH MADE IT DIFFICULT FOR THE CONTACT TO CONTINUE MOVING IN A STRAIGHT LINE. THE VEHICLE WAS TAKEN TO THE DEALER WHO INSPECTED THE FAILURE AND CONFIRMED THAT THE VEHICLE WAS FUNCTIONING NORMALLY. THE VEHICLE WAS ALSO TAKEN TO ANOTHER MECHANIC WHO STATED THE VEHICLE NEEDED AN OIL SEPARATOR TO AVOID A YELLOW LIQUID FROM FORMING WITHIN THE OIL. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 54,000.

THIS REPORT CONCERNS A SAFETY ISSUE WITH A 2006 BMW Z4 WITH A 3.0 ENGINE AND AUTOMATIC TRANSMISSION. THE VEHICLE HAS AN INTERMITTENT PROBLEM THAT BEGAN EARLIER THIS YEAR. THE VEHICLE WILL BEGIN ACCELERATING WITHOUT DEPRESSING THE ACCELERATOR AND WILL SOMETIMES MAINTAIN A CONSTANT SPEED WHEN THE FOOT IS TAKEN OFF THE ACCELERATOR. IT WILL ACCELERATE WELL PAST 100MPH WITHOUT STOPPING. THE THREE WAYS THAT STOP THE SUDDEN ACCELERATION IS TO 1. APPLY THE BRAKES, 2. PUT THE GEAR SELECTOR INTO NEUTRAL, OR 3. TAP THE 'OFF' POSITION ON THE CRUISE CONTROL LEVER. CRUISE CONTROL HAS NEVER BEEN UTILIZED WHEN THE VEHICLE HAS EXPERIENCED THIS UNINTENDED ACCELERATION. THERE ARE NO FLOOR MATS IN THE VEHICLE THAT COULD IMPEDE THE FUNCTIONING OF THE ACCELERATOR. THIS VEHICLE HAS BEEN TAKEN TO THE DEALER FOR SERVICE ON MULTIPLE OCCASIONS. A TECH WORKING ON THE VEHICLE STATED THAT HE BELIEVED IT WAS A CRUISE CONTROL SENSOR, BUT THE SHOP FOREMAN DETERMINED THERE WAS NOTHING WRONG. BMW OF NORTH AMERICA INSPECTED THE CAR AND HAVE STATED THAT 'THEY WILL STAND BY THEIR PRODUCT AND THAT NO DEFECT EXISTS.' I HAVE PROVIDED VIDEO DOCUMENTATION OF THIS ISSUE TO BMW. *TR

HI, MY DESCRIPTION IS TOO LONG , I WILL EMAIL IT SEPARATELY TO NHTSA. *TR THE CONSUMER STATED THE VEHICLE HAD RUN FLAT TIRES AND THE VEHICLE ALSO HAD A TIRE PRESSURE MONITORING SYSTEM. WHILE DRIVING DOWN THE HIGHWAY, ONE OF THE TIRES SUDDENLY COLLAPSED AND SHREDDED. BECAUSE THE TIRES WERE RUN FLAT, THE CONSUMER STATED HE SHOULD HAVE BEEN ABLE TO DRIVE 50 MILES AFTER LOOSING PRESSURE, YET IT GAVE WAY COMPLETELY IN AN INSTANT. EVEN AFTER THE BLOWOUT, THE TPMS DID NOT INDICATED THAT THE TIRE WAS LOW EVEN AFTER THE TIRE WAS COMPLETELY OFF THE RIM WITH ZERO PRESSURE. IT WAS LATER CONFIRMED THAT THERE WAS A NAIL IN THE BLOWN TIRE PROVING THAT IT HAD BEEN LOOSING AIR FOR SOME TIME AND WAS DRIVEN ANYWAY DUE TO THE TPMS NOT WORKING. UPDATED 04/04/08
