Normally I'd say spark plugs but it's too soon for an 08 to be needing those.

For the benefit of anyone who encounters this same issue, they finally brought in a specialized technician from Toyota, who authorized the replacement of the 6 fuel injectors (on warranty) and bingo, the problem is solved! After 6-7 visits to the Toyota dealership and a lot of time lost...

Oh let's see. There is clearly an electrical problem. I have an 08 sienna with 14k miles. Once or twice over last year...display on radio went out. Still playing and came back on during the ride or next time. Over the last few weeks, the car was hesitating when starting; almost like the battery was going. Unplugged the Garmin and all else to make sure nothing draining. Last night, car took 3-4 times to start even after it was used for 6 start/stops running and dropping the kids everywhere. Popped the hood, cleaned off the corrosion [bright blue by the + battery terminal]....car started fine. Checked it this morning. Started at 7 ....at 8 when I went to leave...NOTHING. At 9:30 tried again and after 3-4 tries, it started. Clock has also reset now 2 times on its own. Dealer claims battery is fine and that alternator, starter etc are fine. HELP!

it is settled...despite the "reading" that said my battery was fine, it started leaking bright blue [I assume acid] and after some complaining, they replaced it. No problem since then. Dealer is East of Pgh.

I have a 07 Sienna Van and I love it, but it is driving me crazy because sometimes it cranks without any problems and then others it just keeps going and the engine does not start. I have already had an ignition switch put on and thought that was it, but the problem started again this week. The mechanic said he could wiggle the key and make it do it and then he could make it start good. Help! I love my van but scared to drive it a long distance!!!!!!!!!!!!

Valid concerns. Hmmm...
Have you ever seen a check-engine light? I'd be surprised if you haven't. If you have I'd try to read those codes to find out what it was. Even if the light goes out, the fault should be recorded.
Is it just when starting, or does it run rough at times?

------mcloutier, as you mentioned
My 2008 Sienna is having the identical excessive cranking issues and everything else you described.
No codes are coming up and the dealership I took it to shows no TSB or tips to correct the issue.
Can I please have the name of the dealership that ultimately took care of the problem, so my dealership can contact them for proof of this problem and repair advise.
