Plastic trouble
 We purchased our Sienna from the dealership, but the dealer drove it first, it was a used car.  It was spotless, nice, we thought a step up from our 99 Odyssey.  The car has mechanically been OK, we now have just over 50,000 miles.  Our biggest problem is with plastic bits.  The interior rattles constantly, and has since just after we bought it.  The weather stripping broke on one sliding door (wind noise), on the other it actually fell off (hanging like a rope).  Even with 100K mile warranty, the dealer considers this "trim" and will not fix.  They were quite nasty about it, too, accused us of trying to steal from them, we should be happy to pay.
