No fix for TPM errors?

[f5fstop]

Is the system crap or is the dealer technician under qualified for the repair. Seems to be, even on this forum, more H3s with systems that are working versus systems that are NOT working. In addition, this forum is a very (and I mean very) small sample of those owning Hummer H3s.
My dealer's service manager, two weeks ago, told me he had seen a few come in with the low pressure warning and one was a bad sensor, the remainder were low tire pressure in one or more tires. At this time, this is a joint service department that also services Buicks, and he was referencing all the vehicles that use this same system, including Buick.
So I ask, is the system crap, or is the dealer's technicians crap? (There is a technician on this board who mentioned in another thread a few weeks ago, he has never seen a system he cannot repair.)
