At 10,000 miles the tire pressure sensor valve stems began leaking while the truck was stationary or driving causing low tire pressure. I have had the truck in to have them replaced 11 times and the issue still persists. Ford responded saying the problem was a dealer issue not theirs.

Right side rear outside dual rim will not hold air. Took vehicle to sakelaris Ford in camdenton, mo. First visit they replaced the valve stem with a new one. A week later the wheel was still leaking. Took vehicle back and they said they could not find anything wrong. Wheel continued to leak. Service manager failed to initiate a claim with Ford and has since quit the dealer. Now the dealer's general manager refused to submit a warranty claim for this problem. The slow leak is well documented on various Ford forums on the internet. Most have the same results; the dealers do not want to handle the situation. 2017 is the first model year that TPMS sensors were used on F350 Ford. There is a corrosion problem around the rim opening which leads to the slow leak. I have checked the tire pressure both stationary and while driving using the TPMS monitor.

Valve stem leakage problem on wheels. Corrosion between valve stem and wheel due to dissimilar metal of wheel and stem. Causes sudden loss of air pressure in tires.

The tire valve stems leak. I have replaced 8 valve stems and I have owned my trust approximately 1 year. In some instances the leak rate was very significant, requiring frequent stops to re-inflate the tires. Ford has not addressed the problem - the company simply replaces the valve stems and leaks resume within 2-3 months. This was a major safety issue recently when we were towing a large load in the mountains of Colorado. Ford has refused to acknowledge the problem and have refused to correct the root cause. / the vale stems leak under all conditions - while driving, while towing a load, while parked.

Sudden loss of tire pressure due to leaking TPMS valve stems. This is the sixth similar failure since the vehicle was new in 3/2017. The five previous occurrences resulted in warranty replacement of the TPMS/valve stem unit. There is a sudden loss of 20 to 30 pounds of tire pressure, followed by loss of 20 pounds per day. This has occurred both while driving, and while parked.

The contact owns a 2017 Ford F-350. While the vehicle was stationary, it experienced a series of slow leaks and corrosion between the alloy wheels and the valve stems. The contact took the vehicle to an independent tire facility where the failure was confirmed. The repair facility replaced the front passenger wheel and the rear outside driver side wheel. The contact stated that the failure later occurred with the rear outside passenger side wheel, which was replaced. The manufacturer was made aware of the failures. The failure mileage was approximately 81,000.

At 21000 miles my 2017 Ford F350 drw had two wheels with TPMS sensors leak air at the stems. Both were aluminum rims. Both started leaking on the same day while stationary and under our shelter with no damage of foreign body coming in contact with stems or rims. Both stems were removed by a professional tire dealer and found that replacing gasket didn't solve this problem. There were no replacement stems available for this vehicle in stock or for order because of demand for by other owners needing replacements also.

DRW ALUMINUM WHEELS HAVE A CORROSION FAILURE WHERE THE TPMS STEM MAKES CONTACT WITH THE RIM. THIS CAUSES AIR LEAKS AT THE STEM. IN MY CASE THE LEAKS HAVE BEEN SLOW HOWEVER I FEAR USING THE VEHICLE TO TOW AS A RAPID LOSS COULD CAUSE AN ACCIDENT. I'VE HAD BOTH REAR STEMS REPLACED AND NOW THE FRONT IS STARTING TO LOOSE PRESSURE.

This is a problem with duel rear wheel trucks the high pressure valve stems are failing causing rapid air loss to front and rear outer wheels ( aluminum rims ) this will cause tire failure resulting in crash and or roll over this has happened in motion and stationary
