Nah, my 07 has been flawless. People seek out forums like this to complain, you always hear the worst-case scenarios.
How many people hop on the internet to say "no problem here" on their vans? Noone. Only existing members who subscribe to the threads already, and good samaratins trying to help.
#59 of 109 2010 1st oil change
Oct 20, 2009 (3:53 pm)
so i just passed 1,000 miles on my 2010 le and i am thinking of doing a quick oil change to get out " the fine bits"
when did you do your 1st oil change and did you take it to the dealer or your "local guy"?
did you use regular oil or synthetic and are you happy or do you wish you did the opposite?
thanks for your advice

I did my first at 5k miles and the oil really wasn't that dirty. No metal shavings on the magnetic drain plug, either.
I'm using regular dino oil, thin stuff - I think 5w20.
#61 of 109 07 Sienna LE not starting
Nov 28, 2009 (4:14 pm)
I have an 07 Sienna LE with 32K on it. I have had no trouble with it starting until today. We got out of a store and it would try to turn over but couldn't start unless it was jumped. After shutting it off for a few hours I had to jump it again. The battery says it is fully charged and when I turn the key the lights, radio, windows, etc all work fine. Once it is running it runs well. Any suggestions? I bought it used and it is still under the 90 day/3500 mil warranty from the dealer. Would this be covered?

I'd have the dealer check out the battery strength. Personal experience is that once the battery runs down to the point it doesn't want to start our Sienna takes a few hours of driving to bring it back to full strength- this is after a couple dealer trips where they tell us the battery is good, but low on charge.
These vans have a lot of accessories to drain the batteries. They also drain the batteries if the the doors left open for extended periods (ours was a few days in the garage) even with the lights off.

Remove the battery posts/connections and clean and burnish them.
Corroded battery terminals will often easily supply low level current flow for lights/radio/etc but NOT the 100 plus amps needed to turn the starter over fast enough for the engine to fire.

I too have the annoying hum at 2500 rpms on my 2008 Sienna. I previously owned a 2005 with the 3.3L engine. It was a sweet car and had no such problems. I loved the 2005 so when trade in time came I went for the 2008 Sienna. What a fool I was not to test drive it first. As soon as I drove it out of the dealership I felt the difference with the 3.5L. The numbing drone appears when the gas pedal is feathered at slow speeds or when the vehicle downshifts from 5th to 4th on a long high speed incline. You feel it in the steering wheel, drivers seat, and floor under the driver. The dealer tells me I'm not the first to complain of it and when Toyota Motor Corporation was notified by myself all I got was BS. I've owned new cars and old tin cans but never had an annoying sound like this in a vehicle. This was my 5th Toyota and last because of their lack of response and help. They claim no one else has complained of the issue. Judging from what I've read on the web concerning this problem they don't care and won't be of much help unless the Center For Auto Safety gets involved. Hey Toyota, if you don't think that what happened to GM with Pontiac, Oldsmobile, and Saturn can't happen to you guys...better think again.

FWIW my 07 has no such problems. The engine made Ward's 10 Best, too, for the combination of power and efficiency. Bonus - no timing belt to change, like the old 3.3l V6.
I'll pick the 3.5l any day, twice on Sunday.
#66 of 109 Motor noise at cold engine start up
Feb 19, 2010 (5:33 am)
we have a 08 Toyota van and it seems to me to have excess motor noise at cold start up. My last toy van with 123K miles did not have this noise when i traded it in.
new van has 48K miles,
has anyone else had this problem or is it a problem.
I plan to change oil and filter and maybe add some lucas oil stablizer to motor. Hopefull this will quiten it down some. After motor is warm it run fine.

The timing chain on the 07+ Sienna is a little bit more noisy than the belt on the 06 and prior models, FWIW.
Toyota added insulation to the firewall to compensate, but outside you'll hear more noise.
