NHTSA Complaint #10370887 — 2007 FORD F-150

I BOUGHT A USED FORD 2007 F-150 SUPER CREW CAB 4X4. NEW TIRES WERE PUT ON BY THE DEALER. I HAVE HAD THREE SEPARATE INCIDENTS OF THE TIRE VALVE STEMS BREAKING AND CAUSING DEFLATION WHILE IN MOVEMENT. AFTER TWO BREAKING I WENT TO THE DEALER AND COMPLAINED. I WAS TOLD THEY HAD NO REASON OR COMPLAINTS OF THIS OCCURRING.WHILE TRAVELING OUT OF STATE I HAD A THIRD STEM BREAK. EACH TIME I HAD NEW STEMS REPLACED. I BEGAN RESEARCHING FOR MYSELF AND FOUND AN ARTICLE WHICH STATED THAT FORD HAD COMPLAINTS OF DEFECTIVE VALVE STEMS ON ALMOST ALL THEIR VEHICLES INCLUDING MERCURY'S. AFTER TWO ATTEMPTS AND COMPLAINTS TO MY DEALER I WENT TO A LOCAL TIRE DISTRIBUTOR AND THEY RECOMMENDED REPLACING ALL RUBBER VALVE STEMS WITH BRASS HIGH PRESSURE VALVE STEMS. AFTER DOING THIS I HAVE NOT HAD A PROBLEM. THE COST FOR RUBBER STEMS ARE AROUND $1.50 EACH AND I PAID $6.00 EACH FOR THE GOOD STEMS. THIS IS A SMALL PRICE TO PAY FOR YOU AND YOUR FAMILY'S SAFETY. MY DEALER STILL HASN'T CONTACTED ME WITH A SUGGESTION AS TO CORRECTING THE PROBLEM. FIRST INCIDENT WAS AROUND APRIL 5, 2010 AND SECOND INCIDENT AUGUST 24, 2010 AND THIRD WAS OCTOBER 18,2010. *TR
