2011 Toyota Avalon Sedan Limited 4dr Sedan (3.5L 6cyl 6A)
First Avalon 
 Purchased in April 2010. My first Toyota and hoping the Avalon lives up to it's name. At the present I am experiencing a problem with the back window shade. It goes up and down at random times. Have no idea what sets this off. Any suggestions before I take to dealer?
