2008 Toyota Sienna Minivan LE 8-Passenger 4dr Minivan (3.5L 6cyl 5A)
Bad Rear A/C line, low quality tire, and bad rear most mirror molding
 Bought Toyota Sienna 2008. Today is July 6, 2012. About ~4.25 year and 39000 miles, and facing following problems already:1) Rear A/C line leaks. Dealer said it was due to rust after leak test. Then I request to see myself and saw oily residue on rear passenger side tire area. No rust at all. Dealer said, originally, line will have to be replaced. Then I think he had a slip of tounge and said leaky o-ring. Whatever it is. The cost to repair is $900. I went ahead with the repair since dealer (Elmhurst Toyota, IL -chicago area) scared me that it could damage the compressor if oil keep leaking.2) both sides vent window molding falling $85 each to repair3) original tires lasted only 30k.
