Hey everyone. I used to post in the "old" forums when I bought my wife's Dark Blue Sienna XLE Ltd. in 2006. Glad to see that everyone made it to the new forums....myself included.

Our Sienna has 50,150 miles on it, but is just shy of being 3 years old...so, of course...the warranty has run out on "non powertrain" issues. Well the 60/40 power third seat is acting up. The "40" part works fine, but on the "60" side, you push the button...the seat raises out of the storage area and locks into place...but the seat back won't go up. We took it to the dealer and paid a $50 diagnostic fee and they told us that there is something wrong with the track and that it will need to be replaced. The cost? $849 + tax!! I think it sucks that it broke before the 36th month, but the mileage is what put us out of warranty. The car has made a couple of trips to Florida but we hardly put the seats up and down. I guess an extended warranty would have been the way to go....but that's life...huh? That seat should have lasted at least 5 years without acting up, and the worst part about it....you can't manually use the seat...or we would do it! :mad:

Anyway....we decided to trade it in on a new 2010 Salsa Red Sienna XLE Ltd and the dealer is giving us a fairly good deal. What do you think?

They are offering us a fully loaded 2010 Sienna XLE Ltd with Power everything..including back up camera, RSE, NAV, Bluetooth and pretty much every option that our current van has, for $35,000. They are throwing in Sirius radio. (I had a "brain" installed into our current model after purchase for around $500) They are giving us $18,500 for our trade (our vehicle is very clean), and since we are trading...the tax on the deal is only $1,250. Our payoff is $14,781...so after all is said and done, we are financing $33,000.

That is the same amount we financed when we traded our 2000 Lexus RX300 in on the 2006 Sienna XLE Ltd. BUT...we got 1.9$ financing for 60 months then....

NOW the best they can do is 5.9 for 63 months. The payment is about $612 monthly...and we were paying $579...with only 2 years to go. We are getting the new one for peace of mind, and to have a "new" vehicle. Since the payments are similar, it is not like we are going way out of our price range. Also, this is a simple interest loan, so we can refinance any time after the first year and pay off the existing loan without penalty.

HOWEVER....We are LOSING laser cruise (which is no longer an option) and HID headlights, as the new one will have neither. Also...we like the wheels on our 2006 model better.

What I guess I am getting around to asking is: Does anyone have the 2010 Ltd...and are they very happy with it? I realize it is basically the same car that I already have, but am hoping that they have made some minor adjustments for the better. I understand the headrests are now "active headrests" and will move forward in the event of a crash to secure the head of the passengers, so that safety feature will be good to have. Also, I am pretty sure they have addressed the issue with the rear tailgate, as we had the recall done on our 2006 model.

Sorry for the long post...but wanted to get all the information out and questions asked. Looking forward to your comments and tips.

Thanks,
Haze

Re: 2006 Sienna XLE Limited...third row problems.

That's interesting. I had a similar (not exact) with the 40 side where the 3rd row seat wouldn't come out of the storage area. I found out that if I pushed down on it, it came out. What I discovered was that the carpet that was over the latch obstructed it. Once I moved it out of the way, the problem went away.

Re: 2006 Sienna XLE Limited...third row problems.

You can still get the Laser Cruise and HID here in Colorado on 2010 models. In fact, they are in the same package. Personally, I would just pay the repair bill and be happy, but that's just me...

Re: 2006 Sienna XLE Limited...third row problems.

Welcome to the new neighborhood! :)
Sorry about the broken seat. :'(

Well.....we all have our own individual priorities and budgets.

Personally, if I had "extra" money I might go with a new car. But.....
It generally does not make good economic sense. In the long-run, it is usually less expensive to keep a car as long as possible....within reason....until the repair bills start piling-up regularly and it costs substantially more to fix it than it is worth and/or you don't have any viable alternatives, or there are some BIG improvements in a new model, or a truly debilitating component failure occurs that affects the primary usability factors, or an important safety feature is compromised.

$850 vs $33K??? ??? ???
Or, just "live with it" until something else "major" requires attention and then decide at that time what to do.
How often do you really "need" to use the broken seat, or change its configuration???

You might also try "complaining" to Toyota corporate. USA Customer Experience Center: +1-800-331-4331.

Do what's best for you.

YMMV.
Good Luck!! 8)

Re: 2006 Sienna XLE Limited...third row problems.

Didn't want to start a new thread on this. Our Sienna (06 Ltd) has the same problem with the powered third row seat as the OP (although our options don't include buying a new one ;) ).

We do have a 2006 Limited Fwd with Limited Package #3 (i.e. with powered, split 60/40, third row seat) with 55,000 miles on it. Same as OP, the "40" part works fine, but on the "60" side, you push the button...the seat raises out of the storage area and locks into place...but the seat back won't go up. Dealer estimate says $435 for the "60" seat sub frame, $347 for the "40" seat sub fram and $736 for labor (estimate was for both sides, although the "40" works just fine).

Has anybody else experienced this?

Why is it necessary to replace the sub frame, if only a switch (!!!!) is broken?

Is there a way to DIY anything in regard to this?

Is there a way to fix it cheap?

Re: 2006 Sienna XLE Limited...third row problems.

Sounds like they may have a problem with the seat sub frame?? Why do they want to replace both if only one is defective? IF there is an updated seat sub frame then I'm quessing there was a problem with the original set-up. See if the dealer can search for a TSB on this? Extended warranty?

Re: 2006 Sienna XLE Limited...third row problems.

I have *exactly* the same problem with almost the same price estimate - on my 2006 Sienna Limited. However - the price the dealer wants is only for the '60' side.

The funny thing is I don't use my power seats all that often. I can't believe this is an isolated incident - I'm also wondering what part could possibly be that expensive and break. I mean is this something that can be bent back into shape?

I was thinking of calling the Toyota customer support line to see if this was a common issue.

Re: 2006 Sienna XLE Limited...third row problems.

If you are out of warranty and are a little bit mechanically inclined... I suggest you check out alldata.com Toyota's manuals are there (for the sienna) along with tsb's etc. It could give you an idea of what is wrong... The subscription is around $30 for the year...

cheers,

Re: 2006 Sienna XLE Limited...third row problems.

At ALLDATAdiy.com, a subscription for a single vehicle is US$26.95 for one year, but the real deal is US$44.95 for five years, which is what I bought. I have two current vehicles for which I want technical information, and additional vehicles are only US$16.95 for one year and US$29.95 for five years.

While the ALLDATAdiy material is not as nicely presented as the genuine Toyota manuals (e.g. scans instead of native PDF documents), I think it is well worthwhile for anyone intending to work on their own vehicles... especially if they have more than one. I bought 5 years for each of our two most recent vehicles (the Sienna and a Ford Focus) - total, US$75.

I have not yet used the TSBs in ALLDATA, but if I had this sort of problem I would be checking them!

Re: 2006 Sienna XLE Limited...third row problems.

I'm reluctant to subscribe unless I know there is a section specifically on the 3rd row power-assisted deployment system. I actually downloaded the service manuals from a different site, and they only included the manual 3rd row seats.

I also checked the service bulletins - and there doesn't seem to be one on the 3rd row seats - so perhaps this isn't that wide of a problem - or there are so few Sienna limiteds that Toyota hasn't chosen to do anything about it.

I'm at my wits end just looking at it visually and looking at the digram for the manual 3rd row seat. If one of you guys has a subscription to alldata, could you take a peek to see if there are diagrams for the power-assist 3rd row (that's in the Sienna limited).

Thanks.

Re: 2006 Sienna XLE Limited...third row problems.

I would be very happy, if I would be able to get that information as well!!

From what I've been told, it is a switch, which is broken (or just non-functional), but it is the whole sub-frame, which needs to be replaced. Reason for this still missing... In essence this means, I will have to pay more than 1,000 US-$ for a 5-bucks piece of equipment to be broken!!! Is that true ?!?

If there is anything to be DIY-able about this, I REALLY would like to know!

Problem in my Limited still exists - I'm just hesitant to shell out this much money for that small piece to be broken.

Re: 2006 Sienna XLE Limited...third row problems.

What exactly did they tell you? Because if it's a tiny switch that needs a replacement electronic part - I have no problems soldering a new capacitor/transister/circuit element in.

I am assuming you and I have exactly the same problem. So to reiterate, it's my '60' portion of my 60/40 third row. The entire element comes out of the bay, but the seatback won't deploy (it stays folded) - and the unit beeps - and my 3rd Row Seat light is on in my dash.

Since I don't have a diagram of the motorized version of the 60/40 3rd row seat, I'm not sure what element I need to get at and where. I took a peek at the bottom - and I think all of that stuff on the bottom of the seat is for pulling the entire seat out of the bay. I suspect that the motor/electronic elements are in the seat back because I can hear a click in there when it's trying to unfold that portion.

I have started to pull the covering off the back of the seat back - you unscrew the screws on the plastic bag hanger, the pull very carefully on certain parts of the leather seat cover - it uses plastic tabs to hold it on - got to be careful not to break them. Next step is to remove the metal retaining rings that hold the seat cover together. In the Toyota manual it mentions to cut these off - and to replace them when reassembling with new rings. Problem is I don't have a bag of these rings to reattach them, so I might just use some pliers to get them off - and then back on again later.

Haven't got much farther than that. Would like to get more information before I proceed any further - because at this stage, I can pretty much reverse everything I did pretty easily.

Thoughts?

I checked in ALLDATAdiy; the subscription is specific to year (2004) and drivetrain (2WD in my case), but not to trim level. For instance, my LE does not have a power hatch, but the provided information includes at least detailed component placement for items specific to the power hatch. Strangely, under "Seats" there is detailed information for the power driver's seat (which is typically only in LE trim and higher), but no mention of powered third-row seats. This may be a problem, but if the power third-row seats did not appear until after 2004, then my view of the material would not tell us anything useful.

Re: 2006 Sienna XLE Limited...third row problems.

I forget what year, but POWER 3rd-row came after 2004....maybe 2006 or 2007ish??? ??? ???

A quick glance at Wikipedia ( http://en.wikipedia.org/wiki/Toyota_Sienna ), shows 2006.
Scroll approx 1/2-way down the page to the section that says [Model Year Changes].

Sorry, I was just so baffled by the pricetag, that I didn't listen carefully enough. No more info though (at least yet).

...as is the very exact same problem (and symptoms) in my car...

Not really. But I amable to use a soldering iron as well, so if you are able to dig out some info, that would be very much appreciated.

Re: 2006 Sienna XLE Limited...third row problems.

Frank,

I found this website: http://www.toyodiy.com

You can get a really detailed diagram of the seat. I downloaded a PDF of it...which I'll try to post somewhere.

My guess is the dealership doesn't try to fix the actual broken part, and replaces most of the seat - primarily part #79202, which according to this site is a $510 part!

There's a cover part under the rear seat - part #72955A - I think the electronics may be under that part that controls the seat. I'm going to check under that panel this weekend and let you know what I find.

Re: 2006 Sienna XLE Limited...third row problems.

Here are the diagrams - on second thought, I think the problem might be these computers - part #89715 - a $228 computer. Both seats have them. I'm thinking of trying to remove the one in the broken seat - and inspecting it for burnt out capacitors, etc. The computer in the other seat is the same part - so I might remove the other one and swap them to see if its the culprit.

Re: 2006 Sienna XLE Limited...third row problems.

Sorry to spam with more info - but I found the part at my local Toyota dealer's parts website - the specific electronic component for the left side seat - and it appears to be cheaper than the price I mentioned from the other website. Here is the info:

It shows up in both the electrical and collision catalogs - note that they show both left and right in the catalog - but the part numbers are exactly the same:

Item Number MSRP Core Price Price
8971508010 $205.43 $0.00 $160.55
Electrical - Body electrical - Power seats - Control module
Control module, rear folding seat, sienna 2006 - 2007

8971508010 $205.43 $0.00 $160.55
Seats and tracks - Rear seat components - Control module
Control module Left - Third row, left side seat W/power seat 2006 - 2008

I guess that all that is left is determining if this is indeed the part that is broken. This is substantially cheaper than the initial amount quoted by the dealer.

Re: 2006 Sienna XLE Limited...third row problems.

WOW...great find and sleuthing ;D 8)....hopefully it is the solution to this problem that seems to be plaguing some Siennas with power 3rd-rows....and that Toyota is being a tight-wad about. ??? ::) :eek: :mad: :mad: :mad:

Most dealership techs are trained to REPLACE entire systems not "fix an individual component". This is common for most brands, foreign or domestic. And these days it is getting more and more difficult to even find individual components because many things are "packaged" together and manufactured/sold as a complete system. :mad: :'( :'( :'(

Let us know....

YMMV.
Good Luck!! 8)

Re: 2006 Sienna XLE Limited...third row problems.

Ug. I got most of the leather covering on the back of the seat taken off (and it looks easy to get back on)...but I can't get at the computer because the seat back is folded down. The computer is on the other side of the (looks like aluminum) seat back frame. Anyone have an idea how to ratchet the seat back up? The dealership actually closed the seat back at my request a while back so I could stow the seat.

Looks like the seat back uses some kind of motorized gear to raise and lower. If I could find the motor connections, I might be able to apply power to the motor to raise the seat back.
