MY Z4 HAS ABOUT 70,000 MILES ON IT AND I JUST GOT IT BACK IN 6/20015 AND I NOTICED WHEN STEERING THERE IS A SORTA STICKING PROBLEM WITH IT AND IT KIND A WANT TO DRIFT SIDE TO SIDE ? NOW THE STEERING INDICATOR LIGHT COMES ON AND ITS LIKE A OLD TYPE STANDARD STEERING CAR. AND WHEN RESTARTED IT WORKS FOR A LITTLE WHILE AND THEN ALL OF A SUDDEN IT DOES IT ALL OVER AGAIN. THIS WOULD BE A REAL PROBLEM FOR A OLDER PERSON IF THIS WOULD HAPPEN , MAY CAUSE A SEVER ACCIDENT . I DID SOME INTERNET RESEARCH AND I DON'T THINK THIS IS A SOLO EVENT FOR ME. I DID ASK MY LOCAL DEALER AND THEY SAID THERE WAS NO RECALL ON THIS CAR. AS FAR AS I CAN TELL I AM THE 2ND OWNER ?

AFTER SITTING IN HOT DIRECT SUN FOR OVER TWO HOURS, THE STEERING ON THE CAR IS DIFFICULT TO MANAGE. THE STEERING GETS EXTREMELY LOOSE AND YOU HAVE TO HOLD TIGHTLY TO THE STEERING WHEEL TO KEEP THE CAR FROM SWERVING. THERE IS NO ISSUE ON A COOL DAY, NOR IS THERE AN ISSUE ON A HOT DAY IF THE CAR IS PARKED IN THE SHADE. THIS HAS BEEN HAPPENING FOR THE LAST 3 YEARS TO MY 2003 Z4. THE CAR IS GARAGE KEPT AND STORED IN THE WINTER. IT HAS NEVER BEEN IN THE RAIN OR SNOW AND IS WELL-MAINTAINED. AS OF SEPTEMBER 2015, THE CAR ONLY HAS 12,000 MILES, SO IT SHOULD NOT BE A WEAR AND TEAR ISSUE. THERE HAVE BEEN OVER 300 COMPLAINTS FILED ABOUT THIS ISSUE SINCE 2003. THE INVESTIGATION DONE IN 2010 WAS CLOSED IN 2011, AND YET HUNDREDS OF COMPLAINTS REMAIN UNANSWERED. IT SHOULD BE CONFIRMED WHETHER OR NOT THE INVESTIGATION INCLUDED TESTING THE CARS AFTER THEY HAVE BEEN IN THE DIRECT SUN ON A HOT DAY FOR SEVERAL HOURS. IF THE TESTING WAS NOT COMPLETED UNDER THOSE CIRCUMSTANCES, THE TEST WOULD BE FLAWED AND THE INVESTIGATION SHOULD BE REOPENED. IT IS UNACCEPTABLE THAT HUNDREDS OF PEOPLE ALL HAVE THE EXACT SAME ISSUE, AND A SAFETY ISSUE, AND NOTHING IS BEING DONE ABOUT THIS.
