2001 Toyota Sienna LE 3.0L 6 cylinder from North America


Best value family and stuff hauler out there


Check Engine Light (CEL) illuminated once at about 150k miles; code readout was the one suggesting catalytic converter or downstream sensor as the root cause; CEL went out on its own after a month, not to return.

General Comments:

We love it. It's reliable and steady to a fault.

It comfortably hauls our family of 6: two adults, two small kids, and two large dogs.

Sufficient engine power for our needs (i.e. it doesn't tow anything), but does carry lots of stuff inside and on the roof rack.

Soft suspension.

2001 Toyota Sienna 6 cylinder from North America


Very reliable family transportation


The oxygen sensors and catalytic converter were replaced at 80,000 miles. They were NOT replaced again between 80,000 miles and 403,000 miles.

The water pump was replaced at 300,000 as a preventative measure, as it was still in good working condition.

Various seals and gaskets began leaking oil at around 100,000 miles. Replacing seals and gaskets did not stop all of the leaks. Between 200,000 miles and 403,000 miles, began adding quart of oil every 2,000 miles, and we no longer replace the leaking gaskets and seals.

General Comments:

The Sienna was designed for hauling eight people plus a lot of cargo, or five people and a LOT of cargo. It does that job very well. It is a smooth highway cruiser, and makes long weekend trips a pleasure.

Its large size makes it harder to park. Many indoor parking lots are designed for smaller vehicles, so it is sometimes necessary to hunt for a large parking space.

The view to the rear is poor, so we always walked behind the Sienna before backing out of the driveway to make sure no kids were nearby. The newer Sienna's have an option for a rear view camera, which would solve that problem.

The first two rows of seats are comfortable for long trips. The third row is really designed more for kids than adults, and adults would not like riding in the third row for more than an hour or so.

The gas mileage has been good for such a large vehicle. We averaged around 21 mpg for the first hundred thousand miles, and between 100,000 miles and 403,000 miles averaged closer to 22 mpg. About 90% of the miles are highway miles, cruising at around 70 miles per hour.

It will soon become a "backup" vehicle, but we hope to keep it to at least 500,000 miles.

2001 Toyota Sienna LE 3.0 1mzfe from North America


Could be better


ECM at 77K.

Transmission issue at 77K.

General Comments:

1998-2003 CE, LE, XLE, 1mzfe motor.

Faulty ECM ends in 60, the replacement version ends in 63, warranty is 96 months or 80K miles, whatever comes first. This is a TSB and the number is 012508 (TSB - Toyota Service Bulletin).

The issue's you may notice are, pinging or knocking, you are running too lean; this causes engine failure eventually.

Motor may run rough.

Power surges or power loss at certain times, climate also makes the issues vary.

Transmission may hang when cold.

2001 Toyota Sienna CE 3.6 gasoline from North America


A great family car


Over its first 330,000 miles, the most common problem was the "Check Engine" light would come on. Eventually, we figured out that the problem is the light itself, it comes on when there is nothing wrong with the car. So, I personally check the oil level and fluid levels once a week, but ignore the "check engine" light.

When I tell the staff at the Toyota dealer to ignore the fact the "check engine" light was on, they smile, as they also know the light, not the engine, is the problem.

After 330,000 miles, the engine and transmission both function like new, and have only needed routine scheduled maintenance.

General Comments:

After 330,000 miles, the car runs like new. The engine has great acceleration, and we get 20 mpg in the city, and 23 mpg on the highway. The Sienna makes 500 miles trips as comfortable as sitting in the living room.

Thanks for the mention of the CEL quirk. Here's why I appreciate it: at about 150k miles (2012) on mine that I've owned since 90k miles (2007), the CEL illuminated. The code readout was the one suggesting catalytic converter or downstream sensor as the root cause, depending on source. While I was mulling over further diagnostic and repair options for about a month, the light went out on its own, never to re-illuminate. That is, until last week when it lit up for the 2nd time since I've owned it. However, I found the root cause: a faulty auto-shutoff sensor/switch on a gas pump I used had allowed gas to overflow during a routine fill-up; apparently the excess pressure resulting from the overfill triggered it. Once I used that tank of gas and bought gas at another station, the CEL went out again.
