Especially after unfolding from the floor. There is no way a normal person can pull the head rest in and out.
I am not sure if WD-40 will help?
just want to see if anyone has the same problem.
Thanks
All sienna owners should check their head rests because most of them might not use the 3rd row in order to notice the problem.
Best wishes
It is too precarious a situation to override indefinitely, or to trust to anyone other than the factory trained who have probably seen this in the course of their work. This is one of the very few times I would reccommed the dealer over a reputable independent repair facility.
If you have children or unwitting adults as passengers there could well be an unintentional opening of the door when least wanted.
Be safe.
Ford has the answer.....!
From the new 2007 Ford Edge PR..
"The electronically shift controlled transmission also features a variable displacement pump, which matches the amount of fluid that gets pushed through the transmission to driver demand, making it more efficient."
At full lift-throttle all of the FWD Toyota/lexus vehicles begin an upshift just as the engine RPM drops to idle. With the engine at idle the upshift will exhaust/use most, or possibly all, of the pressurized ATF.
Now if you happen to re-apply foot pressure to the accelerator pedal just as the upshift begins the engine/transaxle ECU will "know" to delay the onset of engine until the low engine "idle" RPM can build enough ATF pressure to complete the corresponding downshift.
The most obvious answer would be to increase the volume of the fixed volume ATF pump so enough pressure/flow could be provided for two sequential QUICK shifts with the engine at idle. But then most of that added volume would be bypassed, disapated as heat, as the engine RPM rises above idle.
Ford's answer, apparently, is to have a variable displacement ATF pump so it can be switched to high volume when quick/SOLID shifting is required with the engine at idle. Makes me wonder if that allowed them to eliminate the ATF pressure bypass relief spring/valve also.
That would REALLY increase transaxle efficiency.
A second option would havre been to have an ATF pressure storage accumulator (like the ABS pumpmotor asembly). But putting one of those in an already "crowded" six-speed transaxle is probably out of the question.
Anyone know if any of the newer Toyota/Lexus transaxles have either? Absent one or the other the delay/hesitation issue will undoubtedly continue.
Thanks for the information. Having Mechanical Engineering background, I also was remotely suspecting such design issues as a possible cause of the hesitation problem but without solid understanding. I am wondering if you can provide the source of the information, particularly on the Toyota related information. I would like to get some more in-depth technical information if possible. Thanks for your help.
But I only discovered that after realizing that was what my RX300 was doing that resulted in a somewhat odd seat of the pants feeling at times.
Thanks.
it's kind of a clear fluid.
I used to own a AWD Town and country and I had the same problem. Not sure if it is common to AWD
The brakes totally fails, the pedal goes to the floor and it does not slow down, so I coast until I stop. However, when I release the brake pedal and then reapply the brake it works fine. The dealership is unable to finds error codes and brakes work fine when it is their hands. It has happen 3 times in 18,000 miles, I scared that the brakes will not work the next time I reapply the brakes.
I was badly injured by a defective hatch on my 2005. The dealership and local reps denied problems. I filed an incident report to nhtsa and engaged them in some dialog. As it turned out, Toyota had issued a technical service bulletin for the problem 1 year before my accident. I would encourage you to file an incident report as it may help keep the automakers honest and us safer.

I brought my data from Edmunds and my laptop. The salesperson said that they had a 2007 XLE Limited AWD demo and asked whether I was interested. I answered, "depends."
The car had 4,000 miles on it. While I was looking at the car I noticed a nine inch by one inch scrape (like a side-swipe) on the panel before the rear tire. I pointed it out to the saleman.
During the negotiation portion the salesman quoting MSRP and I said 'any Demo car with damage we don't talk discounts from MSRP, we talk discounts from invoice price.' We settled on $30,780 minus the current $1,500 rebate - which I thought was great.
However, once I returned to the dealer with the bank check I noticed the invoice said "FWD" not "AWD." Upon further inspection, I noticed it said "XLE" not "XLE Limited." I then checked the car itself and sure enough, it was an XLE with the #3 package not a Limited.
Essentially, the dealer was giving me the car for a few hundred off invoice cost, which may be an OK deal but not a great deal. The manager wouldn't go any lower. I voided the transaction.
Did I do the right thing?
However, the issue is if a car has 4,000 miles on it and has body work damage invoice price is still too high.
I'm not sure about your area, but in most areas you should be able to get 2007 below invoice or at invoice.
Yes.
That this dealership tried to sell you a 6,000 mile 2007 "demo", with body damage at MSRP is laughable. ha ha ha. Run away!
The damage knocks another $800 (at least) off of that.
The dealer was DREAMING, no way it's worth that much. It's used and abused, literally. :sick:
I must disagree. Siennas are significantly better than Chrysler minivans or Chevy Uplanders.
According to Consumer Reports' survey of owners, 79% of Sienna owners would buy the car again compared to 49% of Chrysler Town & Country owners and 36% of Chevrolet Uplander owners.
In terms of reliabilty, only the Sienna ranked "better than average." Honda and Kia ranked "average" and Chrysler Town & Country, Dodge Grand Caravan, Dodge Caravan (V6), Ford Freestar, Nissan Quest, Buick Terraza, Chevrolet Uplander and Saturn Relay all ranked "below average."
Whether $30K is a good deal or not for THIS CAR is the subject of this topic. Obviously, Siennas in general are worth $30K because Toyota doesn't seem to have trouble selling brand new ones. In fact, the easiest sells seem to be XLE Limits that sell close to $40K.
run the engine check the fluid see if the fluid cerculate if not then the pump not working
Stopped turning hard. Will see how long it lasts.
