Now on my 4th Jazz EX, if i remember correctly, all had TPMS and I can't say I've had much problem with any of them.
In 10 years maybe 2 or 3 issues when the warning light has come on.
It's important to follow the correct procedure, as detailed in the manual, when resetting the system and drive a few miles on relatively straight roads, after resetting, so that the system 'learns' the new setting.
There are better TPMS systems around, but I would rather have it, than not and accept the odd false alarm.
