Vehicle

2009 Toyota Sienna XLE 7-Passenger 4dr Minivan AWD (3.5L 6cyl 5A)

Review

Very distressed at the fuel economy. Driving around Henderson, NV local driving average fuel economy is less than 8/9 mpg. On the freeway at constant speed i.e. 70 mph, fuel economy 14 mpg is the norm. My 1999 Yukon with the 350 gets 18/19 mph hwy. Overall the car is exceptional in ride and quality. Severe power limitations with Toyota battery. Insufficient reserve power to start car after door or other accessory has been on. I routinely have to jump start or charge the battery. I have been back to the dealer twice to check battery drain or if defective batteries.

Favorite Features

Interior layout and cargo capacity with the 2nd row out and 3rd row folded down. When we travel, cargo is in back and two 90lb labs take up the middle.

Suggested Improvements

Increase size of battery. It is severely limited in capacity considering everything on my vehicle is electrical and there are many courtesy lights on when door(s) are opened.
