STEERING
IN HOT WEATHER THE POWER STEERING GETS EXTREMELY STICKY AND WHEN MAKING A TURN SUCH AS ON AN EXIT RAMP THE STEERING WHEEL HAS TO BE PULLED TO RETURN IT TO THE STRAIGHT POSITION WHICH RAISES THE DISTINCT POSSIBILITY THAT THE CAR COULD GO RIGHT OFF THE RAMP IF NOT CAUGHT. THIS PROBLEM ALSO CAUSES SWERVING WHEN MAKING SMALL STEERING CORRECTIONS ON THE HIGHWAY, THE CAR CAN SWERVE INTO ANOTHER LANE. DEALERS ARE UNWILLING TO ADDRESS THIS ISSUE AND THE ON-LINE Z 4 FORUM INDICATES THAT THIS IS A VERY COMMON PROBLEM APPARENTLY DUE TO DESIGN FLAWS. *TR

STEERING
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 PREDICTABLE. SPOKE WITH MY BMW DEALER WHO STATES THEY HAVE NOT HEARD OF THIS PROBLEM. THIS SEEMS UNUSUAL GIVEN THE NUMBER OF COMPLAINTS I CAN FIND ON LINE. THIS EVENT OCCURS EACH AND EVERY DAY WHERE THE AMBIENT TEMPERATURE GETS ABOVE 75 AND WILL NOT CORRECT ITSELF UNTIL THE CAR COOLS DOWN. CLEARLY A TEMPERATURE RELATED ISSUE. *TR
