Bar-None, the best van we have owned
I will be replacing the lower ball joints this weekend. Other than that, it's been trouble free.
The one issue which really isn't important, is the exhaust noise when the engine is cold on start up. It sounds like a diesel, but quiets down once it is warm.
For the size of this vehicle, it gets excellent gas mileage. We average 22 city and 24 highway. The engine performs fantastically and has incredible torque and power. You would think it is a V8. Smooth and strong throughout the RPM range.
These Siennas are very roomy and great for long distance traveling.
I use synthetic oil and added a transmission cooler at 60,000. I would suggest you add a cooler to yours.
The transmission shifted poorly at 60,000 miles, but a good fluid flush and transmission cooler fixed that problem. Toyota claims WS trans fluid never needs changing. Don't believe them. Newer models don't have a drain plug, but 2008 and older models do.
I was worried that we would have terrible tire wear, but our tires are still good 35,000 miles later. It must have been an AWD issue.
If you are interested in a transmission cooler, you can see my install here:
Would you buy another car from this manufacturer? Yes
