I have had the same problem with the tire pressure light I bought the vehicle in October 2004 after totaling my previous Suzuki Grand Vitara. I recenltly had to change all 4 tires due to wear and they are the same size except that the original was low profile. Does that have some thing to do with the light? The light has only come on once since then. The warranty is long gone.

We had the same problem with the tire pressure light. I think it means that it noticed a change in tire pressure (not necessarily that the tire pressure is low).

We put air into the tires and the light went on, and went on and off randomly over the next few weeks. I think there might be a reset button somewhere, look in the manual (I haven't yet.)

P.S. Anybody have problems with the rear hatch not opening correctly (often not opening at all)?? We fixed it by hand and it worked for a bit, but then stopped opening after a bit. The local Toyota dealer wants $800 (yes, eight hundred dollars) to fix it.

You say your Toyota dealer wants $800 for fixing the hatch? Try stopping by an independent mechanic in your area to see if they charge less. We always take our cars to one when the warranty runs out.

I too have a 2002 Sienna. Got ripped off at the dealer for a 60K miles checkup. They wanted $1190 for all sorts of stuff which they didn't do. I have since maintained my own car. I change oil and filter every 3k - 3500 miles. I change drive belts and iridium spark plugs every 60k miles. air filter every 10 k. all parts bought factory spec and on-line for about 1/3rd the price. I wrote a long blog on how to change the back 3 spark plugs on a Toyota transverse mount V6 (i.e. sienna). I've now done it twice. First time took me 1 hr 15 minutes. The second time, took me just 45 minutes. Folks may want to Google "changing spark plugs sienna" and it's like the first or second link.

Wife broke the back latch also at 105K miles. You can go on-line and find out how to -repair- the latch. I used a thin, long screw, some epoxy and repaired it. Toyota dealers with old databases can actually have a bad part number for the manual latch and want $80 for the part. It's actually $37 in the San Francisco Bay Area and I can't remember the part number, but I found some experts that knew about the glitch in the database and had the part in stock. Two other dealers gave me the run around.

Took me 30 minutes to install the latch with basic tools. Process basically involves working from the inside back of the vehicle and pulling off the center panel screws, carefully pulling off the edges of the big rear cover panel (careful not to break to tear pop rivets), and then removing about half a dozen bolts that hold the latch and locking mechanism in place. Not sure why I removed the license plate, but I did, and then I replaced the latch, put bolts back on, tested the door, and then put the back panel back on. Just had to remember to slip the panel corners under the plastic trim on the left and right side of the windows for original fit. They wanted around $500 to repair at the dealer and "overnight." What phonies! Personally, Toyota should have spec'd a cast metal piece as many cars are having that problem.

As for the tire pressure light, I constantly have to reset since I wear tires like crazy due to lots of road trips. With car stopped, insert key into ignition, and turn on engine but not all the way so it doesn't engage the starter. Hold down reset tire button (left side of dash below steering column) for several seconds until the pressure light blinks a few times, and that means you reset the light. When you start the van again, the light should stay off until you need to check the tires again for wear or pressure.

With exception of getting ripped off at the dealer the first time, and one other time to get my timing belt replaced at 90K miles, I've done everything else. The Sienna works like a champ. And yes, lubing the rails on the power door and cleaning contacts are good suggestions.

I have a 1999 Toyota Sienna, and my problem is the PWR DOOR light keeps coming on, even though all doors are closed.

Once in a while we can clean the sensors on the side doors and close tight, and light will go out.

Last week I noticed the battery getting weak, so I bought a new battery after a tech ran a diagnostic test and there was dead cell. 1 week later, PWR DOOR light comes on and then the battery light, and the new battery was completely dead. Tech put in new battery and ran a new diagnostic, and it said power draining and or alternator problem. How can you tell if it is the alternator or if the PWR DOOR is draining battery? Test was not specific and I do not have money for the dealership to work on it. Any help would be greatly appreciated. I even thought about removing fuse to PWR DOOR, but I don't want to mess up something else. Thanks!

I have a 2000 Sienna with 110,000 miles.

The low tire light has been most of the time.

The van still runs great, even though the only thing I have done to it is oil changes.

It eats tires and has since the day I bought it. It will eat the front tires off in 10,000 miles. I took it to the dealer and they said tire pressure being 6 pounds under caused it. I guess they think everyone is an idiot. I have had the front end aligned at least 4 times and it still eats tires.

It is such a good van other than the tire issue, I just keep driving it and might keep another ten years... I just will never buy another car from that dealer...

Is buying a 1999 Toyota Sienna with 163k worth it? It is a one owner vehicle and supposedly runs great. Asking price is $3950.

I'd say it's a good deal. You'll have trouble finding Toyota's that old with less mileage. Try to talk the price down as low as you can though. Kelly Blue Book states it to be worth only $3350 (For the lowest model CE), $3785 for the mid-class LE, and $4750 for the top of the line XLE (assuming it really is in good running condition, and is free of any major body damage.) If it's a high end model, then yes, it's an excellent buy. If it's a low-end model, then no, the price is too high.

In response "Is buying a 1999 toyota sienna worth 39xx?" That's tough to say... probably yes but talk them down in the price.

I just bought a Toyota Sienna 1999 with 171xxx miles on Saturday for 3500. It's a fully loaded XLE (highest model) and I ABSOLUTELY love it... if you look around, you might find a better deal if they won't go down in price.

I, as well, have a problem with the tire pressure light going on and staying on. Hasn't been an issue. And it drives EXTREMELY nice!!

I have a 99 Sienna with 98000 miles. A garage tells me I need to change the 3 engine mountings because it is worn out and the engine shakes during acceleration. The mechanic said if I don't change it on time, the shaking will end up breaking the wires and it will cost more to fix it. It costs about $600 to change all three mounting. Does anyone have the same problem? Should I trust him?

The tire light has a reset that should be done every time tires are messed with.

The motor mounts should be replaced if the mechanic recommends.

This vehicle is worth repairing small stuff.
