The Sienna leaves a lot to be desired in the exterior construction - namely door handles that break off. I have had 3 door handles basically disintegrate on this vehicle. They literally break off the door. Poor design and or weak materials. I have never in my life owned a car with door handles that break apart. This is a definite design flaw which they should correct.
This van is simply amazing. At 180K received letter from Toyota asking if while driving you hear a humming noise, bring it in. The following week dealer installed a brand new transmission, free of charge. Now going on 350K. Changed radiator, timing belt twice, brakes and oil. Van should be good for another 200k, at least! Extremely satisfied.
Acceleration and ABS.
Doors handles could have been made sturdier for Canadian winters.
We're now at 135,000 miles and it's simply unraveling. We just had the inner tie rod replaced ($300). A rear hub assembly had to be replaced ($600). We were told that there are leaks in the transmission, engine, power steering and a rear shock. The suspension is awful and it rattles like crazy. We keep leaving puddles of fluids wherever we park. We need to sell it or it's going to burn a deeper hole in my pocket with all the repairs it needs.
It's roomy for our family of five. It's easy to get in and out for everyone.
Trunk space is tiny. I would say reliability, but perhaps we just have a lemon considering most people have had good experiences with reliability.
Purchased the car new because we have 3 kids and needeed space for all their stuff when traveling. The transmission went in the first 9 months, was replaced with a new one and haven't had a problem since. Very few repairs besides the usual upkeep.Air conditioning system needed repair after 5 years. Has over 150,000 miles and the ride is still smooth and the kids have grown in 10 years and they all still fit comfortably in the van. We'll keep this until it no longer wants to go.
