My family loves this truck. We haven't had any real problems.
We did repair brake drums/rotors. At about 30,000 miles the truck developed a pretty severe vibration during braking. Dealer looked and found that there was warping of the rear brake drums/rotors. I don't know a great deal about mechanics, but evidently that put additional strain on the front. Toyota was wonderful and replaced all 4 brakes and rear drums under warranty.
Only other thing (which was probably our fault) was that the driver's side rear window latch broke off- so the side window did not open properly. I suspect that this had something to do with my son in the car-seat by the window! Regardless, Toyota replaced this too under warranty.
The service department I visit has the "Satisfaction Guarantee" program and has alway gone above and beyond. We do own another Toyota vehicle as well.
