Toyota Sienna, Van
#975 of 3687 1998 transmission failure
May 22, 2001 (10:33 am)
At about 41,500 miles our van required a tow to the dealership. Symptoms were no power to the wheels and loud noises from under the hood. About a week earlier, I had scheduled a service appointment due to a gear whine noise at low speed and a high pitched noise at highway speeds. The Sienna broke down a day before the service appointment.
Toyota replaced the transaxle and torque converter under warranty. I was told the problem was not the harmonic balancer that plagued some '98s but the dealership did not know what component failed. This van made a few long trips (1,000s of miles) but otherwise nothing unusual. The dealership had serviced the transmission at about 18,000 and 35,000 miles.

Thanks go out to Wolverine and his post on "sliding door creak noise reduction"
Toyota TSB # BO003-33 issued 2-99.
I took my 99 Sienna XLE in today and got the job jone at no charge. The dealership replaced 2 junction boxes and also put in a noise kit. Total parts 209.49 and total labor 105.00 on the invoice, but a big no charge on my end. So far, very quiet and door functioning smoothly. Once again, thanks to the Wolverine. Feel free to e-mail me at tnovismsn.com if you have any questions about this issue.
#977 of 3687 ALL OWNERS WITH POWER SLIDING DOORS!

I am posting this for a second time. If I get anywhere the response the "whistling noise" post got, I would be thrilled!
Take your power slider in the "open" position, place yourself like you are getting into the van closest to the "B" pillar. Let the power door slide closed. Does it immediately reverse back like a elevator, or does it exert high pressure before reversing??
If you wave your hand in front of the "B" pillar optical device, does the door reverse itself and re-open?
Please post your findings!!!!

Where is the optical device?

As I am to understand, it's high up on the B pillar, looks like grey plastic. Some years of Sienna I believe do not have it.
So, try out your door(s), and let me know the results of the test.

I am unaware of any such optical device. I do not believe any of the manufacturers offer this. I could be wrong about this, but in my various test drives of different vans a feature such as this was never demonstrated. All power doors (Toyota and others) were "demoed" as reversing when encountering an obstacle. Power doors are kind of a "catch-22"...the motor needs to produce enough "force" to close and latch the door securely, but this same amount of force will be a bit uncomfortable (to a person in the path of the door) before the excessive "load" causes the door to reverse. My salesman described it very accurately "it will be uncomfortable (may even cause bruising), but should not cause any damage such as broken bones, and or smashed fingers."
Regarding the comparison to elevator doors...most (if not all) reverse via a mechanical switch, not because of an excessive load on the door motor. The "switch" is the black (usually black) piece on the end of the door. When this piece is pushed in a switch is triggered and the motor reversed.
I have tested the power door by placing my arm in the door while closing to see how much force was required before the door reversed. It was a bit uncomfortable, but not too bad. I've also had the door close while standing in the opening. A firm push on the door reversed it immediately.
Could the power doors be improved upon? Yes, of course, but the more complicated/sophisticated the electronics/mechanicals the greater the potential for problems with reliable operation. There are already complaints of the power doors not operating properly.
On a final note of this rambling post, We love our power door and would buy another van with them in a heartbeat. Also it may possible to adjust the amount of force required to reverse the motor. Ask your dealer.
#981 of 3687 power sliding doors issue
May 24, 2001 (4:23 pm)
Here we go again. 99xle with power passenger door. just recently took it back to dealership and they "reset" the computer for the doors and supposedly took care of the problem. Took it in again for the creaking and that was taken care of. now the door will open automatically, however it will not close. just makes a click. anyone else had this problem?

I'm the one that prematurely praised my Toyota service guy for fixing my squeaking, rattle-prone rear sliders with a little lubrication. Five days later the rear doors are louder than ever, "creaking" every time I start or stop and pretty much rattling the rest of the time. The only good thing is I've stopped noticing the minor-by-comparison dash and window rattles.
I don't have or know anything about the other problems listed here. I repeat (as in my previous posts) the car drives and rides beautifully; but what is the deal with Sienna's body structure? It is clear to me the problem is as my service advisor implied....too many big doors and not enough strength in the body.
It may be that my Sienna will be squeaking along, trouble-free, with the same timing belt and spark plugs twenty years from now; but for me a $32k XLE that after 6 months rattles like a 10 year old car is unacceptable.

I disagree that it's just a problem of the body design since I haven't experienced any of the squeaks and rattling. I've had my 2000 LE for almost nine months and have over 10k miles.
Cliffy, what do you think? Dardson, what if you asked for a test drive on the lot with the service guy - I'm sure their other cars don't squeak & rattle - thus disproving the "they all do that" explanation? I think the dealer needs to fix this for you.

Dardson1 We've had our Sienna since April of last year and we don't have any squeaks,rattles etal-so I don't think your problem is intrinsic to the Sienna as a van
