Hesitation every time you step down on the gas when a down shift is involved.
No spare.
No power passenger seat.
No memory drivers seat.
The hesitation makes for an unsafe condition in traffic.
I find it hard to believe that any company, especially Toyota, would manufacture a car with no spare.
Mistakes happen. Toyota is not immune.
It's true, they have a spare tire kit available for the AWD model; but they are equipped with run flat tires.
You placed it under the wrong year. XLE Limited AWD is under 2004.
Toyota is investigating the hesitation issue. do a google search for Higlander hesitation and you will find a Dec. '04 Post-Gazette article on it. I would think that whatever problem you have in Sienna is the same as the Highlander and Lexus mentioned in the article.
