Chrome or Metal caps oxidize to the aluminum stem and sieze.....Then turning the cap off to air up the tires will break the stem , and cause all of your air to rush out. Then you cant refill the tire because the stem is broken....

Chrysler has sent us Numerous Bulletins and letters, that they will NOT cover this type of damage to a TPM sensor under warranty.

The quick and easy solution.....USE ONLY PLASTIC VALVE STEM CAPS.

 

Amazing how, as a consumer, we never hear about these things!

Thanks for the tip! My tire woe's are over!
