 Have nothing but brake problems.  Rear 
brakes hum when stopping - told this 
was "normal noise" for a Sienna.  Very 
irritating.  Had rotors sanded down 
after only 15,000 miles. 1 week later 
had metal crunching sound when 
stopping.  Was told "nothing looks 
wrong".  Was also told by dealer not to 
come back with rear brake noise that 
there's nothing they can do.  Drivers 
side slider door rattles.  Rattle in 
rear seats about drives me nuts Yes, 
it's been in to be fixed under 
warranty.  Still rattles.  Was planning 
to buy it at end of lease.  I'm just 
glad i'm not stuck with it and can turn 
it in and be finished with this lemon 
when the lease is up.
