Well, I have an 05, and let me tell you from experience, it works as advertised.

People that don't own one thinks the alarm keeps going off. Not so. It'll sound one time, then the idiot will stay on. It won't sound again until the system has been reset. No need to pull fuses, or rewire the X. The system works perfectly.

SUVs are top heavy, and more prone to rolling. With the added weight, they are also more likely to roll a tire off the bead. Lots of data online about this topic.

Mine went off once, I had a low tire. Later that day I shot 35 PSI in all of them. Problem solved, alarm reset, hasn't sounded again in a month.

If you haven't read the new regulations, here ya go:

In April 2005, NHTSA issued a rule requiring automakers to install systems in all new passenger cars and trucks by the 2008 model year, beginning a phase-in with 2006 model year vehicles.

All vehicles will have this soon...
