I have to say that I absolutely hate these TPMS monitors, It should have never been mandated that car companys be required to use them..The biggest problem is that they tend to leak and it seems like nobody in my town carries the gaskets for them..I haven't called Mazda to see if they have them yet...but I think if laws are passed that they be used, they also need to pass a law requiring every tire store to carry replacement parts. Thanks to all those lazy people out there that never checked there tire pressure and having accidents due to there own negligence. Im done!!
