Air bags
8 reports
“TL* THE CONTACT OWNS A 2008 BMW Z4. THE CONTACT STATED THAT FOR SEVERAL MONTHS THE AIR BAG WARNING INDICATOR WAS FLASHING. THE CONTACT STATED THAT THE AIR BAG WARNING LIGHT WAS CONSTANTLY ILLUMINATED. THE VEHICLE WAS NOT TAKEN TO THE DEALER OR AN INDEPENDENT MECHANIC FOR A DIAGNOSTIC TEST. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 60,000.”
Steering
5 reports
“VERY ERRATIC STEERING. CROSSING THE CROWN OF A ROAD WILL PULL ONE WAY AND THEN QUICKLY PULL IN THE OPPOSITE DIRECTION UNLIKE ANYTHING I HAVE EVER DRIVEN. ALSO SAME EFFECT WITH TRYING TO STAY IN LANES WITH ANY COMMON DEVIATION. THIS IS WORST AT HWY SPEEDS BUT DOES OCCUR AT LOWER SPEEDS AS WELL.”
Engine and engine cooling
2 reports2 related recalls
“The contact owns a 2008 BMW Z4. The contact received notification of NHTSA Campaign Number: 22V119000 (Engine and Engine Cooling) however, the part to do the recall repair was unavailable. The local dealer was contacted and confirmed that the part was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.”
Electrical system
2 reports
“WHILE TURNING ON A CONSTANT RADIUS CLOVER-LEAF ON-RAMP (RIGHT OR LEFT), A SUDDEN CHANGE IN STEERING ANGLE WAS REQUIRED TO AVOID AN OBSTACLE. AS THE ELECTRICALLY-ASSISTED STEERING WAS QUICKLY ADJUSTED, A FLAT SPOT (OR A HEAVY SPOT OR A DELAY IN BOOST) IN THE STEERING WHEEL/FEEL WAS ENCOUNTERED. IN OTHER WORDS, MORE FORCE WAS REQUIRED THAN EXPECTED TO QUICKLY CHANGE THE STEERING ANGLE. IF THIS IS NORMAL, IT COULD INTERFERE WITH EMERGENCY MANEUVERS TO AVOID OBSTACLES. PERSONALLY, I FIND IT TO BE UNSAFE AS THE STEERING FEEL IS UNPREDICTABLE. THIS UNPREDICTABLE STEERING FEEL OCCURS ANYTIME I NEED TO MAKE AN ABRUPT CHANGE IN STEERING ANGLE. *TR”
Service brakes
1 report
“This complaint is regarding a large number of 2008 BMW cars exhibiting the ABS failure light. Mine is a Z4 with @ 65K miles and was diagnosed by a certified mechanic as the ABS module failure - a high ($3000-$4000) cost repair. If you use this search term - "how common is bmw 2008 ABS module failure?", you will see that a multitude of cars from 2008 (and in other years and models using the same module) are affected by and exhibit this dangerous issue. What has to happen for BMW to be forced to repairing this chronic, safety-compromising, and widespread issue? This is not something that happens to other cars as a result of age. This is a design flaw that directly affects safety. Now I would like to sell the car, but I can't afford to fix it and, in good conscience, I cannot sell it if it is dangerous.”
