I'm in MI.
Dealer? I took it to an indy I've been going to for years. And there's nothing to "admit", the darned things aren't supposed to fail... if it's a lousy design, they're all going to go bad early... if it's just a lousy part, it's just yours and mine.
Don't forget that minivans often don't get serviced all that well... mommy's too busy and all that. This failure isn't going to be found on a cursory inspection.
As far as "admitting" anything... admit hell -- the darned thing's out of warranty, it's on my nickel, lousy design or no.
I don't like it, but I accept it, and I certainly won't try to get any money out of either Toyota or the local dealership... I don't trust the mechanics there, so I never go and have no rapport.
The fact that my ATF was black after only 46k bothers me more than the stupid bushings. Maybe I should sell it; at least resale is stellar on these things.
#3511 of 3687 A/F sensor replacement
Mar 21, 2006 (6:24 am)
I see online that replacing these sensors is common for the Sienna, and other Toyota models as well.
Have they been covered under an emmissions or goodwill program yet? At $300+ a pop, these are becoming an expensive item to maintain on our 2000LE.
We've replaced the two sensors on the engine manifolds already, and now need to replace one again.

Same here brought to dealer prior to 36,000 and he looked confused. I knew that it was something wrong mechanically. All he told me was that sand got down there and scratched the glass in the exact same place as others said.
Denied the fact that this happened too all of the siennas I've seen. They never replaced my weather stripping or window. Just blew the sand out with air. The front wind shield also of low quality glass and scratches very easily. Also the passenger window motor died right after warrenty was up. I've seen this on other Siennas.
This an a few other things, will force me not to purchase another Toyota product.

We had the scratched glass too - window was replaced - fortunately covered under warranty
#3514 of 3687 2004 Sienna with check engine light constantly on
Mar 21, 2006 (6:14 pm)
I bough a 2004 Sienna on June, 2003. Today my unit has 49500 miles. Last week my unit turns on the check engine light. When I went to the dealer, they told me that the computer was registering codes P0301, P0302, P0303, P0304, P0305 but the unit does not show any signal of malfunction. They reset the signal light, but 2 days after the signal turns on again. I return the unit to the dealer and after 5 days with the vehicle in the dealer they gave me back the van saying that they donít found any malfunctioning. Today (two days after) the light turns on again. Do you have any idea?

maybe there is a TSB on it, for example i found this:
there may be another more recently issued TSB.
see if the VIN is in the expected range for this TSB.
even if not, this suggests the manufacturer had a problem with the coil packs produced and installed in a number of vehicles. your codes indicate misfiring (in every one but one cylinder? you sure you didn't omit code 0306?).
sounds like all they are doing for you is resetting the CEL (check engine light). are they going through all the diagnostic steps to deduce misfiring?
you could have an intermittent wiring problem to/from the coil pack or defective coil pack. then again, it might be something they aren't seeing because perhaps it is occuring when it is raining outside with moisture being kicked up into the engine compartment? ask if there is something they might do to rule out something that occurs as a result of excessive mosture (spray bottle test).
print out the TSB (all the pages of it), and bring it back to them.
hope it helps.

#3517 of 3687 Suspension Problems on a 2002 Sienna by bpendergast

If any 2001/2202 Sienna owners get a chance to inspect the rubber bushings in their suspension assembly (as seen on attached photos) in their Siennas it would be appreciated. Bear in mind we did not have any warning that there was a problem - no vibrations or bumps. It was only found when the dealer was dealing with the front brake pads at 88000 kms. A previous maintenance inspection at 72000 kms did not reveal any problems. We were told this was potentially dangerous to drive with this condition.

I just found your post.
we have the same thing on our 2000 sienna since new.
i think that this causes the van to wander and other things.
what did you do to fix the problem?
