 I've had this van since 50K miles, now has 66K.  First at 50K the rear main engine seal needed to be replaced... major job!  Now at 66K the engine oil light is on. It will be in the shop for awhile, at minimum will need a new oil pump ($800) and it may need an entire new engine!  I really expected much more from Toyota. What good is having the Toyota name if I need to get a different engine?? Very disappointed!
