I have about 43,000 miles on my 2004. The only major problem that I've
encountered was a failed multifunction display unit (data fields were blank,
no navigation, no climate control controls). It died after the car was out
of waranty. The unit costs $4,600 but a call to the Toyota 800 number
resulted in Toyota paying for the part and me paying $190 for labor to
replace it. My unit was one of the old style ones and there is a service
bulletin out on it, although no recall. If your INFO button does not toggle
your screen between the "Consumption" and the "Energy" screens, you have the
old style unit and may someday experience the problem. I understand that
there is no issue with the newer units.

We have some fleet reports from the Dept. of Energy and Canada that show
the earlier model, the NHW11, is good for in excess of 160,000 miles.
About your vehicle, the only problem is it is the first year of a new
model. There are a number of problems found in that model that were
corrected in subsquent years.

Check Ebay and you'll find enough to satisfy. My NHW11 has 64,000 miles
of which I put 15,000 on it. I'm getting better than 51 MPG.
