NHTSA Complaint #10460099 — 2005 BMW Z4

I JUST PURCHASED THIS CAR ON 5/26/12.DRIVING HOME, I NOTICED THE STEERING WHEEL FELT AS IF IT WAS STICKING. UPON ARRIVING AT HOME, MY HUSBAND WHO HAD BEEN IN FRONT OF ME ON THE WAY HOME, SAID I HAD BEEN WEAVING. I EXPLAINED THE PROBLEM TO HIM AND HE LOOKED IT UP ONLINE. I HAVE FOUND THIS WEEK THAT WHEN THE CAR IS COOL, THE STEERING IS GREAT. IT'S ONLY AFTER THE CAR HAS BEEN SITTING IN THE SUN AND BEEN HEATED. ON COOL MORNINGS OR EVENING, THE STEERING IS FINE...FLUID, RESPONSIVE,JUST AS IT SHOULD BE. BUT WHEN IT HAS BEEN SITTING IN THE SUN, IT FEELS AS IF THE STEERING WHEEL STICKS RANDOMLY. SOMETIMES VERY HARD, SOMETIMES LIGHTER, BUT IT MAKES STEERING THE CAR VERY DIFFICULT. AS I PULLED OUT OF MY BUSINESS YESTERDAY I VEERED OVER ALMOST OUT OF CONTROL DUE TO IT STICKING. IT IS REALLY DISTURBING AND WORRISOME SINCE THERE'S NO WAY TO PREDICT WHAT IT WILL DO. *TR
