#3502 of 3687 Re: Glass scratches [gbtw]
Mar 13, 2006 (12:41 pm)
My 2001 also has many scratches on the front windshield. Toyota blames sand. But I've been driving for 20 years never had this problem. It appears to me that the windshield wasn't properly tempered. Also I have a scratched driver side window. It appears every Sienna that model year has these scratches. When I brought it up to Toyota during the 36,000 warrenty they blamed sand. We all know better now. Defective glass. One reason I will probally not buy another Toyota. They act like they never seen these problems before. I'm amazed they havent fixed the problem in the 2005's. It astounds me.

Tell me the scratches in the drivers door glass are at eye level, about 1/4 the way in from the latch side. And are about 7" tall and 2 1/2" wide. I've seen this on a few Siennas.
Our 2000LE came with a defect in the door frame that has caused the weatherstripping to bind tightly against the glass. This has caused grit to accumulate, rather than be brushed off by design, and scratch the glass.
Toyota dealer in Wellesley MA denied this possibility since day one. They did replace the glass and weatherstripping under warranty when new, but the probem persists because of the improperly made door frame.
#3504 of 3687 Trailer Wiring
Mar 15, 2006 (7:36 pm)
Backed into the river last year without disconnecting trailer lights, and since then the rectangular box that converts the cars wiring to the trailer wiring hasn't carried a signal for the brake lights. Other lighting functions work fine.
Can't buy just the converter box, and the wiring assembly is kinda expensive.
Does anyone know what the box does electronically? Is it possible to jumper the brake light wires and, if so, what kind of inline protection should I be adding?

Any update for this dash bulb?
My 99 has the same bulb out.
#3506 of 3687 2001 Sienna XLE with rusting muffler
Mar 20, 2006 (4:28 am)
I also noticed the muffler has many small rusting spots after I noticed the rusting drops on my garage floor. I complained to toyota about it. They ignored me. It had less than 50,000 miles on it when I noticed it. I went to auto zone and bought some heat-resistant paint. I tried to clean it with sand paper and then painted with this ceramic heat-resistant paint. These small holes/spots have not busted yet at this time. I am just wondering anyone has noticed the same problem.
#3507 of 3687 Suspension Problems on a 2002 Sienna
Mar 20, 2006 (2:17 pm)
Have had to have both front arm suspension units replaced on our 2002 Sienna (88000 kms)Minivan due to the rubber bushes breaking away from the metal component arm. The dealer claims its due to driving over rough terrian but this has not happened. ANybody had experience with a problem like this? Seems like it could be a faulty part??

Now that's timely.
Oh yeah I have experience with this.
Took my hitherto flawless '03 Sienna to a trusted independent shop to do a "k" service. It's at 46k miles -- 74,000 km -- so I figured we'd do the 30k "severe" schedule and all inspections.
Sure enough, I need new lower control arms left and right, for $144 each (dealer item), because the $10 rubber bushings have failed. They aren't available separately, of course.
My control arms aren't removed yet, but they appear to have failed in exactly the same way yours have; the mechanic showed me how you can push the arm up and down and the metal sleeve moves around the piece of rubber. Pretty stupid design.
I think the dealer is right on with his diagnosis; the part is not strong enough to withstand use in a 4,000+ lb minivan. I don't think you ruined the suspension over rough roads, 'cuz I know we didn't. It used to be my car before the wife took it over, and neither one of us particularly beats up on cars.
I'm gonna keep the old parts.
As a friend of mine said, "it's a Toyota, so you know there are 150,000 minivans driving around with the exact same problem. It's a car chassis trying to do a truck's job."
I think he's right; I think it's not the end of the world; I think that in a year or three, there will be a way to rebuild these because more and more will fail.
If I hadn't asked to check out a weird noise my wife mentioned, I doubt they would have found it. I bet someone will come up with a way to fix 'em cheaper, and then I'll have my original ones redone.
Thanks for your information and commiseration,

Thanks Mathias - You are the first to have the same problem I've seen -where are you located? So your dealer admitted it was a design problem?

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.
