Tire Valve Problems of Mercury Grand Marquis

I have had two flat tires, one front and one rear. Both happened while the vehicle was parked. Once in my garage and the other in the parking lot of home depot. Both about a year apart. Both tires were inspected by my mechanic and both tires he had to replace the valve stems as they failed. I am glad it happened while the vehicle was parked. I notified Ford motor CO. Of my problems with the tires and received no satisfaction. The vehicle now has 35000 miles on the michelin tires and I can't wait to change tires and valve stems. I read somewhere that the 2007 Mercury Grand Marquis was one of the Ford products that has a defective tire valve stem made in china. It should have been a recall back in 2007.

The next day I went to my Mercury dealer, they inspected the blown out tire and told me that I was driving on an improperly inflated tire and Ford motors would not do anything for me ,but they offered to sell me a new tire and mount it at no charge. I left the dealership and went to a tire dealer that I have used on other occasions for tires for other cars,when he went to remove the blown tire from the rim he found that the valve stem was cracked and could have been the cause of the tire failure,I told him about the low pressure in the right rear tire he pressed the valve stem slightly side ways and the air leaked out, he did the same to the other 2 tires and they seemed ok. He removed the right rear tire it shows several worn spots inside and he recommends changing it also.
