#56 of 63 Any ideas? by kat2800 Oct 02, 2009 (12:47 pm)
I am having the same noise when I go between 50-65mph. If I take my foot off the pedal it stops immediately. Seems to be more when I am accelerating like on an incline or on ramp to the highway. I just bought this 07 LE 7pass Sienna - literally 48 hrs ago. I didn't drive it on an incline when I test drove it. Should I ask them to look at the heat shield and see if it is lose?

Replying to: ateixeira (Sep 30, 2009 11:52 am) I'm glad it is only a rhetorical question--I'm hoping for a long life for this vehicle, which, so far, has been the best I've ever owned. From the looks of some of the posts here, my '01 might be better than a new version. Replies to this message: ateixeira (Oct 05, 2009 11:17 am)

Replying to: oldnslo1 (Oct 02, 2009 6:29 pm) 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.

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 Replies to this message: ateixeira (Oct 23, 2009 9:23 am)

Replying to: islandvan (Oct 20, 2009 3:53 pm) 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 63 07 Sienna LE not starting by kat2800 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?

Replying to: kat2800 (Nov 28, 2009 4:14 pm) 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.

Replying to: kat2800 (Nov 28, 2009 4:14 pm) 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.
