The valve stem issue is random, but has occurred on all 4 wheels. I find out there is an issue when I go out to my car and see a flat tire. This last time I was actually driving down the road (in town thank goodness) and my tire suddenly went flat. I'm worried that this might occur while I'm driving on the interstate sometime.

This is the third time in nine months, you go to leave, tire is completely flat. You have to change the tire, take the flat tire in to have it repaired and installed, you usually end up late because after all, you were heading out the door to go somewhere …

Tired of the stems on my Dodge breaking, leaving me stranded. The air is immediately gone. Has happened 2 times in 2 different tires.
