NHTSA Complaint #10598893 — 2006 BMW Z4

I PICKED UP THIS CAR USED WITH 57000 MILES ON IN MAY 2013. THE STEERING HAS ALWAYS BEEN 'TOUCHY' BUT THE DEALER TOLD ME THAT IT'S BECAUSE IT'S A SPORTS CAR. WHEN DRIVING CAR IN TEMPERATURES AROUND 85 AND UP THE STEERING GETS REALLY 'JERKY' . THIS STARTED IN JUNE 2013 AS THE WEATHER WARMED UP. IT'S MY 2ND CAR SO DON'T DRIVE IT EVERY DAY AND DID NOT NOTICE THIS PROBLEM UNTIL THE WEATHER TURNED HOT . HIGH 80'S INTO THE 90'S. I DIDN'T USE IT MUCH DURING THE REALLY HOT WEATHER LAST YEAR. BUT THE PROBLEM WAS THERE. I THOUGHT IT WAS THE TIRES, HAD THEM CHECKED AND HAD NO ISSUES. TOOK THE CAR IN FOR AN ALIGNMENT IN THE SPRING. THESE PAST FEW DAYS THE WEATHER HAS TURNED REALLY WARM. I DROVE THE CAR TO WORK, LEFT AT 4PM YESTERDAY WITH THE TEMP OVER 90 AND THOUGHT I WAS GOING TO HAVE AN ACCIDENT! THE STEERING WHEEL WOULD NOT GLIDE SMOOTHLY LEFT OR RIGHT. IT'S LIKE IT GETS STUCK, YOU PULL IT BACK CAUSING YOU TO OVERSTEER, YOU PULL IT BACK THE OTHER WAY. I FOUGHT THIS ALL THE WAY HOME FOR 23 MILES. THE TEMPERATURE AND THE ERRATIC STEERING WAS SO BAD YESTERDAY THAT I WILL NOT DRIVE IT. IT IS SITTING IN MY GARAGE TODAY. I CALLED THE DEALER, TOM BUSH BMW IN JACKSONVILLE FL, TO INQUIRE ABOUT THE SERVICE BULLETINS I FOUND AND THIS WEBSITE WHERE OTHERS ARE REPORTING IT. I ALSO CALLED BMW NA AND THEY TOLD ME I HAD TO GO TO THE DEALER FIRST. I HAVE LEFT 2 MESSAGES AND I HAVE A FEELING I WILL HAVE TO KEEP CALLING. THEY ARE AWARE OF THIS ISSUE. YOU CANNOT KEEP THE CAR GOING STRAIGHT WITHOUT JERKY IT BACK AND FORTH WHEN OUTDOOR TEMPERATURE IS ABOVE 85. THIS CAUSES YOU TO OVERSTEER AND DRIVE ERRATICALLY. IT'S VERY HARD TO CONTROL THE CAR. I LIVE IN FLORIDA. THIS IS A SAFETY ISSUE! WHY IS THERE NO RECALL? DOES SOMEONE HAVE TO DIE FIRST? THERE HAVE BEEN NUMEROUS COMPLAINTS, WHAT HAS THE NHTSA DONE TO INVESTIGATE? *TR
