Toyota Sienna 2004+



  • Does anyone have any information on when the build date starts on the 05 Sienna? I'm in the market, but don't want to buy an 04 now and have the 05 come out a few months later, making it a model year old already. I know it will be the same vehicle, because it was just redesigned.

    Thanks in advance.

    I have been looking for an LE with package 7 (disc brakes, stability control, etc.) in So. CA, but the dealer I talked to does not have any LEs with #7, only with #4.

    Are the disc brakes and stability and traction control indispensible for such a large van? Anyone's got good experience with the standard brakes (disc front and drum rear) without traction control?

    take a 9v bat to a cig lighter plug and put it in disconnect then you still have enough power to keep memory up and running that's what theMB dealer does.

    i wonder what will change for next fall as far as option packages, groupings and pricing that would make 18 months with no changes, so something is due........

    The 05 model year vehicles will begin being built in late July and at dealers in late August to the first of September.
  • Others have reported that disconnecting the battery is exactly the method used to cause the computer to forget and then relearn to adjust to your driving habits as stated in the owners manual. On the Honda Odyssey disconnecting the battery causes much of the computer memory to be lost.

    However, not being a Sienna owner, I have no manual to read for confirmation. You might want to check yours, though. It is also possible that this is not a "normal" owner responsibility and it might only mention this in the maintenance manuals used by the techs (no mechanics anymore, eh?).
  • Most aftermarket DVD players are installed under the 2nd row removable seats, not on the front dash. Since the Factory Odyssey dvd player is on the front dash, the dealer can also install one on the front dash, but it costs $2000 plus tax. As you can see, the dealer's installed dvd player is more expensive than the factory installed dvd player, which costs $1,500.
    But no, aftermarket dvd players will not void the warranty on your Odyssey, but I don't know about the Sienna.
  • Car and Driver has selected the '04 Sienna as one of its five best trucks, winning the minivan category. I concur, having had an LE with option pack 7 for over a half year now. Never thought I would say that a vehicle this big is a pleasure to drive, but it is.

    aren't particularly important on a FWD car, since the front brakes do about 90% of the work. Even so, disks are better performing than drums, especially in the wet.

    The real reason they add rear disks is that they work better with the stability control feature (really a glorified ABS system), since they react quicker than drums.

    If nothing else, disks look better with alloy wheels, since you see the brake components!

    Drum brakes are a LOT less subject to loss of braking in wet weather than disks.

    VSC/Trac is a highly desireable option especially for FWD vehicles.

    Having the tires break loose from the roadbed and spin freely isn't very dangerous in a RWD car since you still have front traction for steering/recovery if needed.

    In a FWD vehicle once the drive wheels break traction with the roadbed all control is lost until you lift the throttle lightly and the tires regain traction. Also, if you happen to be traveling in a straight line and lose traction with FWD you may not realize what has happened before you lose control completely.

    VSC/Trac will instantly prevent driven wheel slippage, front or rear WD, and for FWD will similtaneously/instantly dethrottle the engine.

    Having driven many rear wheel drive and front wheel drive vehicles in the upper midwest(snowy winters) for nearly 40 years now, the reality is that it is much, much, much easier to lose control of a rear wheel drive car in winter conditions than it is a front wheel drive vehicle. Get that rear end going sideways on a rear wheel drive vehicle and it is much more difficult to get it back under control.

    You can argue all you want about the theoretical inferior dynamics of driving with the same wheels that are steering, but in the real world with real world drivers, there is absolutely no doubt that front wheel drive vehicles are much more forgiving and provide the average driver much more stability and forgiveness.

    I would argue that VSC and Traction control are much more necessary for rear wheel drive vehicles than for front wheel drive vehicles. In fact, I would never consider going back to a rear wheel drive only vehicle if it did not have some of these advanced features, as it would be too unstable without them.

    Thank you all your comments! Since I put safety ahead of anything else I think I will get the rear disc brakes with VSC and traction control.

    I have lost complete control on snow before in a FWD car and survived simply because the opposite traffic was stopped at a red light at the moment of the accident. Still shudder a lot whenever thinking back....

    OK. I've browsed through the manual, and have not found any references to the adaptive transmission (ECT-I).

    That's strange, because, for example, VW manual screams of it. They even have an 'instructional' video where they mention the 'learning tranny'. I'll have to browse through that manual and see if the learned stuff disappears when the juice is off.

    It does seem that the discharged/dead batteries would occur more often in the minivans/SUVs (more power usage, lights devices to forget to turn off, power sliding doors, radio, DVD, etc). It never is fun not to be able to start your car, but when your car doesn't drive as it used to after a battery replacement, it may add another ounce of frustration, IMHO.

    Anyway, that's not a big deal to me since I only drive Sienna on occasions, so it won't learn my driving habbits. But it is nice to know that dead battery might = different driving characteristics. I'll just have to warn my wife.

    Are there any tools/devices made that allow you to replace the battery and preserve information (other then 9v battery to the power port)?

    Thanks for all of the replies and corretions.

    I try to use after market alloy wheels. At market, it will cost about $250 to buy four alloy wheel. If with four new tires, it will cost about $450. To buy OEM four alloy wheel will cost $800. My van has tire warning gauge. Do any one know how this work? does there have any sensors on the OEM steel wheels now? Does the sensors can be moved to the after market alloy wheels? Thanks.
    Old question, does any one have installed OEM fog lights on LE trim?

    who believes in the advantages of AWD and/or 4WD doubt that FWD or FWD biased AWD is inherently unsafe?

    If it's a good, even excellent, idea to distribute engine drive torque across all four contact patches then why isn't allocating drive traction to one set of tires and directional control traction to another a much better, and clearly safer idea, that asking a single set of contact patches to handle both drive traction and directional control traction requirements?

    What would the argument be if we had FWD cars with rear wheel steering?

    I don't believe FWD is inherently unsafe.

    We've had this thread with you several times now Willard. No more. Enough. Finished. The end. Capice?

    You are missing the fact that the available traction(friction)is much less on the rear tires of a car than the front. With the weight bias to the front of any car or van with the engine up front, the traction available up front is much more than the traction available in the rear. Thus you can lose traction and the rear end can slide out of control quickly on rear wheel drive cars. Two wheel drive rear wheel drive only pickup trucks are the most notorious for this due to the extremely light rear end if they are carrying no cargo.

    You put all the engine torque to the rear where you have little traction and the rear end of your vehicle will easily swap ends with the front on slippery roads. When I was a teenager, we did it on purpose, making donuts this way to have fun in empty slippery parking lots. I also did it once, not on purpose, when on a freeway bridge that had iced up before the rest of the road. My rear wheel drive '72 Chevy paid the price at the end of the bridge as I slid into a highway sign sideways. My rear wheel drive right side rear axle, rear fender and rear window and my insurance company paid the price.

    Get into a front wheel drive car where you have the weight up front and directional steering control of the applied torque and it is difficult to even get the vehicle to spin out.

    I do believe wwest, that you apparently have never experienced a serious amount of winter driving in hazardous conditions, or you would not take the position that front wheel drive cars are somehow more unstable than rear wheel drive cars in slippery winter driving conditions.

    Back to Sienna, I will respond no more as I know it is useless to convince wwest otherwise. I just hate to see other people being misled by misinformed postings.

    Search for "wwest" if you must have more.

    I agree. You posted your cease and desist order #1556 while I was composing my response to Willard. Case closed.
  • Hi, I'm planning on buying a Sienna LE with option #7 and I'm trying to get quotes from three dealers. What fees are legit and not legit when all is said and done? Are there really document fees? I've done a ton of research on the van but not so sure of what to expect when it's time to sign the papers. I just need some good advice on this part about what's real and what's garbage.

    I still remember driving my all drum brake Duster through a large puddle, and then right through a stop sign since I had zero braking ability, so you will be hard pressed to convince me that drums are better in the wet.

    I fell better now, so carry on.
