I have a 2004 Sienna bought in 2003 with 188000 miles on it. Starting to have some repair issues - strutts, lower control arms. What is the highest mileage recorded on a Sienna of this age that is still running? If they have a record of lasting up to 250000 miles or beyond, it may be worth it to invest the $$. The monthly payment on a new Sienna or even a pre-cert used one is high. Anyone know of 2004's with very high mileage?

I don't know of any personally.
But I see taxi-spec 2nd gen siennas all the time, they got to be in the multiple 100K miles driving around all day.
The engines are solid, and all cars will have suspension failures eventually. Take care of your transmission with frequent fluid changes and don't let small problems accumulate.
My previous 2005 sienna needed new struts and shocks all around at 110K miles if it makes you feel better.

My '04 has about 211K miles. Ball joints still tight, LCAs will need replacing in a year or two. Already replaced struts. Tranny needed rebuild at 205K. Otherwise going strong. Minor issues start popping up as it gets older, but will keep it for a couple more years probably.

Go ahead and replace the wear items, if you take care of the tranny and the other wear items as they come up it should last you 250K and some.

Siennacanuck, those are serious miles. We have an '04 LE FWD with 153000 miles that's still going strong. I recently put new tires on and had the front end alignment checked. They said the alignment was spot on and needed no adjustment at all. I read about a guy up in Minnesota that has a Sienna with over 400000 miles and he's still on the original motor and trans. They will go a very long way if you take care of them.

The key to longevity is maintenance. If fluids are changed as directed in the owner's manual, you should have very little problems with your Sienna. If the maintenance has been neglected than expect the repair cost to go up as the van ages. Ignoring a problem because the van is still running will cause more problems down the road. For example, if you have a check engine light on you should determine why the light is on. It could be that the computer has noticed that the air-fuel mixture is a little too rich. Running an engine with a rich mixture will eventually cause the catalytic converters to overheat and melt and become clogged.

I just replaced a catalytic converter. Thermostat was worn out, opening slightly too soon. Engine ran just a few degrees too cool. Not enough to be noticeable on the temp gauge or to trigger an engine light. Had I pulled the codes, perhaps for an emissions test, probable would have seen some "not ready" lines. Engine never made it to normal operating condition and therefore was running rich, lowering the mpg significantly (which was the only symptom I initially noticed). Once I replaced the thermostat, a $20 part, engine made it to normal operating conditions and the computer was finally able to complete operation checks, that's when the engine light came on. I kept clearing the codes for a while but finally broke down and replaced the cat.
She's getting old and wearing out, but good otherwise so it was worth it. In the end we still have our family minivan that we love, and even with a repair as expensive at a cat, way cheaper than a new car payment!

Good info. I'm planning to get a used 2007-2010 Sienna. The resale value is much higher when compare to a Odyssey at the same year. I have a small SUV and I want something bigger with more rooms for road trips. My SUV has the same engine as the Sienna. 6 year with the SUV, no issue what so ever. Would a 2007 with 150K miles XLE selling for $8K a good deal?

My 2004 xle limited (also purchased in 2003) past 250k miles last year. Other than a few rattles when going over rough roads, its holding up very well. I had the front lca, along with struts, strut mounts, ball joints and tierods at about 200k miles. I've also had replaced flex pipe , blower motor, rear shocks, rear suspension bushings, a/c compressor and condenser. I purchased it in 2008 with 110k miles.

Had bought my 2007 XLE (to replace our 2004 XLE with 248000kms.) in 2015 from a Nissan Dealership where i was working as a tech at the time for $9K, $11 with taxes with 78k miles, i had thought it was in KMS but i looked at the speedometer and it was in miles and the car proof showed that it was imported to Canada in 2013. Not bad considering it was more loaded than our 04' which we bought in 2008 for $23k with 76000 KMS at a Toyota dealership.

Now just passed 120K miles and i replaced both lower control arms and ball joints with MOOG parts, front struts and stabalizer links at 117K miles.

Also replaced the rear suspension around the same time ONLY because we renovated the bathroom and we loaded up everything for 1 trip and the tiles were extremely heavy which left the van sitting higher in the front.

Minor things that i have to keep notice of - Ignition coils are failing one by one - replaced 2 already. Common problem with the 2GR-FE engine, as well as the VVT-I oil line is still rubber-steel-rubber but no signs of cracking. The driver's door makes a loud clunk/pop when accelerating or coming to a stop - might be the 04-06 problem that had seam welds coming loose

Easy things to maintain the van at home that i do - Air filter change, cabin filter change, Throttle body clean, brake service etc.

Bought ours new in 2004 - daily driver still going strong at 290,000 miles. Other than normal wear items the door holder, disk changer, seat heaters, and the dreaded sticky cracked dash pad (replaced under warranty) only failures. Regular maintenance, oil/filter/rotate every 5K; belts, plugs, other filters as recommended. Returns about 21 mpg on regular unleaded in mixed driving, doesn't burn any oil, and holds 6 teens for the school carpool. Can't ask for more.

my 2000 toyota sienna has over 320k miles and still going strong. siennas are great cars, 10/10 would recommend. the key to longevity in cars is the maintenance, so be careful with how you treat your car. i would suggest changing the oil yourself and replacing worn down parts as needed, which is unavoidable, to maximize the mileage you can get on your car. the toyota sienna has lasted longer than any of my other cars, both in years and miles. if you see another good deal on a newer model, don’t waste much time considering it because it is worth it.

If you find a high mileage vehicle, any vehicle, you've found an owner that does their own maintenance. Most cars are killed by their owners ignoring minor signs til it just won't move anymore. My theory is folks don't trust mechanics. Often they're right.
The ever growing complexity of cars requiring proprietary information for the simplest task will shorten their life. Financially prohibitive.

I am at about 250K on a 2006 . Cars start to need parts if you have some mechanical skills - you can save some bucks and DIY and keep the thing going for a long long time. Replace your VVT screens, change oil often. Change your plugs and plug wires,Knock sensor wires, thermostat outlet pipe. pcv valve.

I have a 2004 Sienna bought in 2003 with 188000 miles on it. Starting to have some repair issues - strutts, lower control arms. What is the highest mileage recorded on a Sienna of this age that is still running? If they have a record of lasting up to 250000 miles or beyond, it may be worth it to invest the $$.
