Ford Explorer 2007 eb. Tire light would come on. Had Ford dealer check. Adjusted air pressure. Continued to occur. Dealer would try to retrain sensors. Never helped. Said they think it might have something to do with an aftermarket charger for the cell phone affecting the computer. They said it is happening in a lot of cars. Problem continued after sensor retrained even if phone had not been plugged in. New tires installed Nov. 2012 at sam's. they made a notation on the invoice about sensor showing fault. Went several times to dealer and they would retrain sensors. Never helped. Would start again. Finally in Oct 2013 asked dealer to check all four sensors for cracks or damage. They broke down tires, inspected TPMS and no cracks found. Retrained sensors again. Nothing they have tried has stopped the problem. Sometimes now it will say tire sensor fault then change to tire monitor fault. I just hit the reset button until the next time it does it, which is usually just a little farther down the road. Light turns off when engine is turned off, but does it again the next time I'm on the road. Ready to just have the sensor disconnected. Frustrating.

Valve stems on 2 tires leaking without any notice causing tire to go flat. Two times within the last 12 days on two different tires. Upon review of the stem air leaks from the stem when moving/pushing on it to certain locations.

The valve stems on my tires are causing constant low tire pressure, to the point that one of my tires now has a hole in the side wall. The dealership will not help, and I have under 12K miles on it. I've been there 4 times for this problem and it has not been resolved!
