I'm with you Sir. That TPMS is nothing but pain. I've replace at least 6-7 of them between broken valve stems(which is a great reason for the rubber) and breaking for no apparent reason. What I also love is when that damn light starts blinking then the only option to as Chris puts it buy all 4 if costs you a trip to the dealer because they seem to be the only folk that can diagnose WHICH one is bad.
