 No one should have to pay 500.00 dollars to change spark plugs EVER.  But that is the cost to disassemble the front of van and to remove the whole fuel intake.  The power doors are horrible.  The dealer tried fixing but it worked about 3 months.  Plus during there repair they busted plastic molding piece and put a little piece of some type of rubber substance thinking it would hold.  It didn't had to break off on freeway so it didn't kill anyone.  The 17" rims on XLE model are impossible to keep in balance tried many different tires.  So if you like a van that you need to balance tires to go on freeway this is for you.  The only redeeming grace is we don't need to drive on freeway to get to work or grocery store.
