TPMS failures
We hear constantly about the wonders of TPMS systems . Anyone ever have a failure ?

Ok..so now I am a little confused, as well.....Trying to keep an open mind and I am a bit of a tool / gadget nut so I'm interested here.....
Why the heck does the monitor scan though the sensors every few seconds AND it appears to give an instant alarm if it looses the signal, but yet the info being brought out here says the sensor only sends out a PSI reading every 2 minutes??? That makes no sense at all in my mind that the monitor connects and "sees" the sensor every few seconds but doesn't take an actual reading.
Then we get into how often CAN it connect / send a reading and not use up the battery in the sensor? Well that to me is a tough one too.....I know a couple of things relating to it: The sensors are triggered on the motion of rolling along down the road and turns itself off when sitting still. Usually by the time I hit 25MPH or so the monitor is reading pressure of all sensors. So no battery life lost while parked.
My cars wheels sensor also run on batteries, though I am not sure how often they "talk" to the monitoring system built in to give me a warning on the dash. Those batteries are 6 years and 190K miles old and no failures yet. I do know that it takes about 2 minutes of driving after I fill a low tire for the light to go back off, so maybe teh 2 minutes to read thing is right.
All this in consideration, I would expect TST to use similar components and technology.
Again, TPMS is just and extra aid, not a total fix for a problem, IMO....I still do visual / manual inspection often before and during trips.
