Run flats are flat
 The run flat tires on Sienna 's  have a history of problems back to 2006. I had spoken with the  San Francisco Toyota dealer who assured me this was resolved. Yes, indeed, by 19,000 I was purchasing a new set so they resolved it, in favor of Toyota and Bridgestone.  We took into the snow with 4,000 miles on it and about 5 inches of snow, the AWD performed poorly, as compared to the 2008 Sienna AWD we used to own, both with Bridgestone run flat tires.   Further, the brakes warped by 12,000.  Toyota did replace those brakes after a lot of complaining.  We have had Toyota sienna's before. But paying so much for this limited AWD sienna vehicle and disappointments with safety features of tires and Brakes, have made me question Toyota's claim of listening to the consumer.  This will  be our last Sienna.
