Sorry to hear stories of poor service.
We have had our Lux since November 05.
The other day I dropped into Toyota to see if the keys are covered by warrantee as the cover is coming off the buttons, no problem they are replacing both even though one is like brand new.
We have had a few dealings with them as we own 2 Hiace as well and I can say the service department has never let us down. They lent us a car, no charge, when they could not get our Lux through quick enough (slight oil leak in rear shaft bearing), fantastic service.
Nothing is a problem.
