On July 5, 2009 while driving my Mercury Mariner the passenger side rear tire went flat. Cause was a bad valve stem; on September 4, 2009 I had the same problem with the driver side rear tire. The auto tech at wall mart showed me the valve stem was dry rotted and had to be replaced. I also had him replace both valve stems on the front tires, which also showed signs of dry rot.
In July 2008 , "check tire pressure" light became present. Upon placing air in left-rear tire a crack/ leak in valve stem became present. Valve stem was replaced. In August 2008 same issue occurred with right rear stem. Today, October 26th 2008 the issue occurred with the right front valve stem. All valve stems on my vehicle have now been replaced.
