NHTSA Complaint #11388544 — 2013 AUDI Q7

I WAS DRIVING AND THE CAR GRINDER TO A HALT. THE BRAKE LIGHT CAME ON AFTER THE GRINDING. I CALLED A TOW TRUCK AND HE FOUND A BOLT ON THE GROUND THAT WAS HOLDING THE CALIPER/HUB TOGETHER. MY SPEED WAS AROUND 30 MPH BUT IF I WOULD HAVE BEEN ON THE HIGHWAY OR AT A HIGHER RATE OF SPEED I WOULD HAVE BEEN IN TROUBLE BECAUSE THE CAR WOLD NOT MOVE. MY BRAKES WERE JUST REPLACED 3 MONTHS BEFORE. ACCORDING TO MY MECHANIC THE HOUSING FOR THE BOLT THREADS WERE STRIPPED. THE BOLT HOLDS THE CALIPER AND HUB. A MACHINIST IS NOW TRYING TO RETHREAD IT. IT WILL BE A WEEK TOMORROW WITHOUT AS HE FIXES ANOTHER BOLT HOUSING IN THE HUB THE SAYS IS STRIPPED ALSO. MY MECHANIC SAID THAT THIS IS SOMETHING THAT SHOULD NOT HAVE HAPPENED ON A CAR LIKE THIS. THIS IS MY 2ND Q7-- SAME CAR ALMOST EXACTLY EXCEPT IT WAS A 2009 AND IT HAD 110000 MILES ON IT WHEN I SOLD IT AND HAD NO O PROBLEMS WITH IT.
