#2115 of 3687 Possessed minvan needs an exorcism
Aug 21, 2002 (10:05 pm)
1999 Toytota Sienna minivan. Possessed! it locks the doors by itself, sometimes it unlocks, then locks the doors repeatedly, even when nobody is in it! It started a few months ago, then quit for a while and is now back with a vengeance. The good news is that I do not have to ever lock it! But when I unlock the doors, with a remote or the key, it activates the "theft deterrent system". 1999 Toyota Sienna minivan. Possessed! it locks the doors by itself, sometimes it unlocks, then locks the doors repeatedly, even when nobody is in it! It started a few months ago, then quit for a while and is now back with a vengeance. The good news is that I do not have to ever lock it! But when I unlock the doors, with a remote or the key, it activates the "theft deterrent system". This always gets looks in the parking lot. No help in the owners manual or from the dealers (on the telephone).
Please advise on what may be causing it, how to fix it, or at least how to temporarily "deactivate" the alarm system.
Sure I can take it into the shop, but I am asking for help BEFORE I take it in so I do not have to pay an excessive labor charge to pinpoint the problem.
I am sincerely grateful for your help, thanks!
#2116 of 3687 Our Sienna's First Road Trip

We took our 2001 XLE six hundred miles round trip. 100+ degrees, both A/C blasting. No problems what so ever. The three liter has more than enough passing power. Even with a 6% grade, the van would go 80 MPH. The temp gage never moved. Our van is coming up on its first birthday, with just 3200 miles on the clock. Rudy
#2117 of 3687 Sienna Sun Visor Piviots are too loose
Aug 23, 2002 (12:50 am)
Has anyone else had this problem with their sun visors.
On my 2001, when the sun visor is down and to the side - that is when blocking sun coming in the side window, the visor pivot is too loose. When I make a left turn, the visor swings around and hits me in the head. On one occasion making a hard left at a traffic light, my head was in just the right position where the visor swung around, knocked my clip-on sun glasses off, and knocked my eye glasses out of position. It's lucky that the shock and sudden reduction in vision due to suddenly looking out the wrong part of my glasses lens didn't cause me to mess up the turn and plow into the curb.
The passenger side has the same problem, though at least it only hits the passenger during right turns and is less of a safety hazard.
I did see any other entries on this subject in this message board, but with over 2,000 messages, it would be easy to miss, so if this is "old news" I appologise.
The dealer, Miller Toyota in Mannassas VA, has said that they will order new visors and replace them (no argument there), but the service folks do not think that will solve the problem as all of the new Sienna's on the lot seem to have much the same problem.
While this is not a busted suspension, fire hazard, etc., it would seem like a potential safety recall issue as the distraction and potential for knocking a driver's eye glasses off their face could potentially cause the driver to mess-up a turn and take out a pedestrian or another car.
It would also seem like a simple thing to fix - less lubrication, a tighter pivot tube (or however the pivot works), or maybe even a little goop stuffed into the pivit to increase friction.
Any comments, thoughts, suggestions?
I will probably have the dealer replace the visors as I did not notice the problem until the van was > 1 year old, so maybe the new visors will work better for a year. Then I may have to consider a home-grown solution such as trying to clog the mechanism with dust or using a tiny piece of velcro to hold the visor in place with pushed against the door frame area.

Let me guess... there is a non-Toyota alarm installed in this van right? I'm betting that is the culprit in your possessed van. Exorcism will require removing the offending hardware.

cliffy1, i have a question for u and its got nothing to do with siennas. coz u work for a dealer so i'm asking u! hope it's ok.
i was told that toyota is limiting its dealers as to how many vehicles the dealer can order each month and this is creating a very long wait list for customers! the vehicles i'm referring to are the 03' corolla and matrix.

Dealers have never been able to tell Toyota how many cars they want. Well, we can but it doesn't do much good. Toyota builds as many vehciles as they think there is a demand for or, as in the case of the Matrix and Corolla, as many as they can and allocates them to the dealers based upon each dealer's turn rate and units available. If a dealer has had a very slow turn rate relative to the rest of the region on Corollas, they will get very few allocated to them.
This is not a new situation. The Siennas used to be like this, as did the '96 and '97 4Runners. Toyota built them as quickly as they could but demand out paced production. Smaller dealers and dealers that didn't turn them quickly ended up with virtually nothing to sell.

Hi, thanks for your reply, I wish it were an aftermarket alarm, but it came from the Toyota factory-- do you know how to "disarm" the factory alarm?
Thanks again, Flyrod

Are you sure its a genuine Toyota alarm? The reason I ask is because if you live in the Southeast, the regional distributor is not owned by Toyota and often installs aftermarket equipment. This equipment is included on the MSRP label so it looks like factory stuff. It isn't.
If not, I'm as stumped as you are.

thanks for the info.
#2124 of 3687 Sun visor pivots are too loose
Aug 23, 2002 (4:30 pm)
I know what you mean. Our 2001 Sienna is my wife's daily driver, and I only drive it on the weekend. One time I drove the van with the visor deployed to block the sun coming in from the driver side window, and my wife warned me about the visor being loose enough to swing over in a turn. Being an all-knowing guy that I am, I immediately replied, "Nah, that CAN'T happen." Well, the visor swung over and hit me on the side of the head as soon as I made a turn! It did kind of startle me, but it didn't knock off my glasses. I don't if the passenger side visor does this since I've never used it. Somehow we never thought of getting that fixed.
