Toyota Sienna Problems
Problem With Door Mechanism in Electric Sliding Doors
Models with electric sliding doors can develop problems with the door mechanism. The cable in the door becomes frayed, which will damage the electric motor.
Cracks on the Upper Dash Board Surface
Multiple cracks may develop on the upper surface of the dashboard. At this time, the only suggested repair is to replace the dashboard.
Check Engine Light Due to Failed Oxygen Sensor
One or more oxygen sensors may fail resulting in illumination of the Check Engine Light.
Cleaning May Correct Faulty Mass Air Flow Sensor
The mass air flow sensor on higher mileage cars occasionally needs to be cleaned or replaced if sluggish acceleration is experienced or the Check Engine Light is illuminated with a mass air flow meter sensor fault code stored.
Check Engine Light Due to EVAP System Fault
The Check Engine Light may illuminate due to an evaporative emission (EVAP) system fault. Our technicians tell us these EVAP system faults can be difficult to diagnose but it is not uncommon to find a failed charcoal canister or a loose or worn gas cap.

Hi, I was wondering do Siennas have a warning light for the timing belt? I am looking at buying one, and the owners are not sure if it has been replaced. Or is there some other way I can tell? Thanks!
Because the horn and airbag are identified as 1 unit to repair the horn I'm told I have to replace the airbag, too.
Anyone have a better fix?
How do i change my AC, Power steering and other belts

It takes me a long time to get to 3,000 miles. How many months should elapse for an oil change
Toyota Sienna Reviews
2002 Sienna bought new. 113k right now. Tires are a problem; you will not get 1/2 rated of life of any tire, front end is too heavy. Other than that a great vehicle. Tires, brakes, change fluids, and you are good to go. No exhaust replacement yet. Manual and electric door works fine @ 11 yrs old. Keep them lubed. Change trans and coolant at 80k. Wife doesn't want to go to anything else.
I am extremely disappointed in our 2005 Sienna XLE AWD. Once it reached 100K everything started falling apart. We had to replace both sliding door mechanisms long time ago. It's nice that Toyota decided to re-imburse the sliding door expenses - apparently too many people had these issues. Now, check engine light is on - catalytic converter died. And before that the check engine light was on - Oxygen sensor died. Transmission leaking, front differential issues - by now I had to pay $6,000 in all repairs, thinking that I will try to squeeze another 50K out of this car. I am not sure anymore... And yes, we did all regular maintenance, and all the recommended replacements (like timing belt).
Cheap parts and many repairs. We will not be buying another sienna.
Purchased under Toyota Certified Pre Owned program. Limited AWD. Bought it in 2012, just a few short months ago. Van had little over 40K on it. Had everything we wanted in a van; AWD, navigation, tri zone climate control, and all the bells and whistles. Noticed a scrubbing noise during the test drive, but thought cant be anything wrong, or that certification process would have caught it, so I just carried on, and made the purchase. After a month @41000 miles, I felt something was not quite rite about the noise, and how it only made it at about 30-40 MPH, and no accelerator pressed, and no break pressed. Took it to local dealer, and they were able to duplicate it, with me driving. First thought it was center differential, then found huge metal slices inside auto transmission. So ok, good fix the problem. Noticed some clear coat peeling on rear bumper area, and had local dealer look at it. It seems it was not paint from Toyota on the bumper and someone should have caught the huge runs in the paint on the bumper during the certification process. Called Toyota corporate, let them know that one of their dealerships is not inspecting cars correctly, and my transmission had to be replaced, my bumper that has paint runs and clear coat falling off. They had such a non caring demeanor it was totally awful. So corporate does not care if one of their dealers certifies a vehicle, and with known problems. Strike one Toyota. When you start the van first thing in the AM, you hear a knocking noise. Now that the weather is getting colder, its getting worse. Went to Toyota dealer, and was told this was piston slap or cylinder slap. Normal for an aluminum block car to do this until warmed up. We will keep and eye on it, let us know if it gets worse. (I have a 97 Continental and it makes NO noise during start up, and its an all aluminum block as well. So once the nice cold cold winter sets in, I will trek back to Toyota and let them hear the nasty knocking. I may at the next oil change (which is in a few days) take the paper element filter, and save it, along with some oil for an analytical report for metals in the oil and caught on the filter media. So this is my fantastic Toyota Sienna story. Never will I purchase another Toyota. This was our first. Will be our last. I scratch my head all the time at how our 2007 Ford Escape Hybrid can be and has been more reliable than a Toyota. It has over 87000 miles. Trouble free! My advice: If you are buying a Toyota beware. Be even more aware if its a Certified Pre Owned Toyota. Buyer beware!
Bought mine brand new in 2004. It has 120k miles now. So far only two unscheduled maintenance/repairs. One is the A/C which was not getting cold at all. Fixed that under warranty. Now its in the shop getting the front wheel bearing replaced. After reading the reviews here, I guess its pretty common for the wheel bearings to go out at around 100k miles. My other vehicle, Honda Accord, is 5 years older with 170k miles. Zero unscheduled maintenance/repair.
