NHTSA Complaint #11232676 — 2017 FORD F-350

THE TRUCK EXPERIENCES AIR LEAKING FROM ALL OF THE ALUMINUM WHEELS AT THE VALVE STEM. THIS VEHICLE HAS BEEN TO THE DEALER SEVEN (7) TIMES FOR TIRES LOSING AIR. IT HAS REQUIRED SIX (6) VALVE STEM REPLACEMENTS. SOME HAVE BEE REPLACED TWICE. MY UNDERSTANDING IS THAT THE METAL VALVE STEMS USED ON THE 2017 SUPER DUTY TRUCKS WITH TIRE PRESSURE MONITORING SYSTEM FAULTY WHERE THE STEM MEETS THE ALUMINUM RIM RESULTING IN CONTINUAL LOSS OF AIR. THE STEEL WHEELS (DUALLY) ON THE INSIDE REAR DO NOT LEAK AIR. ALTHOUGH THERE IS A MONITORING SYSTEM, AIR MAY NOT BE AVAILABLE RESULTING LOSS OF AIR IN THE TIRES AND DRIVING UNDER LOAD (THE TRUCK IS DESIGNED FOR TOWING HEAVY LOADS - WE TOW A 5TH WHEEL TRAILER) WITH UNDERINFLATED TIRES. INTERNET RESEARCH SHOWS THIS IS A COMMON UNADDRESSED PROBLEM FOR 2017 AND NEWER F350 DUAL WHEEL TRUCKS USING 17"X6.5" POLISHED ALUMINUM 8 LUG 5 HOLE WHEELS. THE PROBLEM STARTED APPROXIMATELY 10 MONTHS AFTER THE TRUCK WAS BOUGHT NEW AT 5,000 MILES AND CONTINUED EVER SINCE.
