I PURCHASED MY 2005 BMW Z4 3.0I LAST YEAR IN THE MIDDLE OF WINTER. INTERESTING TIME TO SELL A CAR WITH A MAJOR STEERING DEFECT THAT IS TEMPERATURE DEPENDENT. AS THE AMBIENT TEMPERATURE INCREASES THE ABILITY TO STEER AND CONTROL MY 2005 BMW Z4 BECOMES MORE DANGEROUS. AT HIGHWAY SPEEDS ON A DAY ABOVE 75 DEGREES THE WHEEL APPEARS TO BE STUCK. WHEN IT FINALLY DOES MOVE THE RESULT IS RAPID LANE SHIFTING, NOT SAFE TO DRIVE WHILE DOING THIS. IN FACT I AM UNCOMFORTABLE DRIVING THE VEHICLE ON HOT DAYS AND LEAVE IT HOME, THE STEERING IS NOT PREDIC…

Owner report 10240250 · 2008-08-29 (August 29, 2008)
ON AUGUST 7, 2007 I TOOK MY CAR TO STERLING BMW IN NEWPORT BEACH, CA BECAUSE I NOTICED THE AIRBAG MALFUNCTION LIGHTS WERE ON ALONG WITH OTHER ELECTRICAL ISSUES. AFTER THEY HAD INSPECTED MY VEHICLE FOR THREE DAYS I WAS INFORMED THAT THE AIRBAG/ELECTRICAL PROBLEM WOULD NOT BE COVERED BY THE BMW FACTORY WARRANTY, AND THE SERVICE DEPARTMENT RECOMMENDED THAT I FILE A CLAIM WITH MY INSURANCE CARRIER. OBVIOUSLY MY INSURANCE COMPANY DENIED THE CLAIM, BECAUSE AUTOMOBILE INSURANCE DOES NOT COVER LOSS DUE TO WEAR AND TEAR, MECHANICAL OR ELECTRICAL BREAKDO…

The front headlight wiring harness is flaking off and could cause a short and lose your lights at night and cause a accident. there has been no recall and it's happening to all of the bmw cars that had this environmentally friendly insulation. It is a hazard because you can lose both headlights without notice and have a accident. It has been going on for years according to several mechanics I've spoken too. It also is a huge expense to replace.
