NHTSA Complaint #10731482 — 2004 BMW Z4

I HAVE NOTICED ON WARM DAYS THE STEERING BECOMES STICKY AS IF THE POWER STEERING IS COMING ON AND OFF. THIS CAUSES A OVER CONTROLLING OF THE CAR AND MAKES IT DIFFICULT TO DRIVE. I FELT VERY UNSAFE. I TOOK THE CAR TO BMW ROADSHOW AT MEMPHIS AND WAS TOLD THE PROBLEM WAS THE ELECTRIC STEERING UNIT AND WILL COST $4000 TO REPAIR. I RESEARCHED THE INTERNET AND WAS SHOCKED AT THE NUMBER OF COMPLAINTS GOING BACK AS FAR AS 2009. I CALLED BMW CUSTOMER SERVICE AND WAS TOLD THAT IT WAS NOT THEIR PROBLEM. SOMEONE IS GOING TO GET HURT IF IT HAS NOT ALREADY HAPPENED. BMW KNOWS OF THIS PROBLEM AND HAS CORRECT IT IN LATER MODELS AND THEY KNOW HOW IT FIX THE ISSUE. IT APPEARS THIS IS AN AGE RELATE ISSUE, NOT MILEAGE, AND THESE CARS,2003-2005 ARE OUT OF WARRANTY. IN MY RESEARCH I SEE THAT NHTSA IS AWARE OF THIS PROBLEM BUT HAS CLOSED THE ISSUE. THIS IS A SAFETY ISSUE AND THIS INVESTIGATION NEEDS TO BE REOPENED.
