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.

Toyota Sienna Problems
Multiple cracks may develop on the upper surface of the dashboard. At this time, the only suggested repair is to replace the dashboard.
One or more oxygen sensors may fail resulting in illumination of the Check Engine Light.
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.
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.

Toyota Sienna Questions and Answers
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
Toyota Sienna Reviews
I purchased a 2004 Sienna five years ago. So far, the unscheduled problems have been for the 2 rear seat belts not working and sliding doors getting stuck. I had to make the sliding doors manual by cutting the cable so we can open and close them. I called Toyota about the seat belts but they said that the warranty has expired. Are the seat belts supposed to last only 36,000 miles??
Other repairs have been for the front wheel bearings and brake rotors.
After having a Ford Explorer with problems I was hopeful that my 2004 Toyota Sienna would be a better choice for the family hauler. Boy I was wrong there. The quality of this vehicle is marginal at best. The list of problems I have had over the years includes:
- Heated Seats stopped working
- Radiator had to be replaced
- Lights on overhead console are completely out
- Sunroof is constantly loose and rattles
- DVD player/unit had to be replaced (under warranty)
- Weld on drivers side door was poor quality and required an entirely new door
Now one might question about how the vehicle is driven. It is driven in normal daily around town doing the usual thing people who own minivans normally do - haul kids to/from activities, mostly by their mom. Normal oil changes and major maintenance was done on this car.
Suffice to say, this will be the last Toyota I ever purchase. Very disappointed with the quality of this car. Sadly the Explorer I previously purchased was better, which is not saying much.
I bought my Sienna LE in November 2010, it has 55000 miles and only minor problems,low tire light won't go off add rubber at front of windshield curled up on both sides and the rubber by the back doors was coming up , dealer fixed without writing it up, but today I went to get in it and noticed the plastic frame around the driver's seat has broken at the front outside corner I can see where the plastic is broken.
I bought my 2011 Sienna LE in 2010 shortly after they came out. Although I had read commentary about the cheaper plastic interior, I liked the car alot and it came with lots of standard features - even a backup cam. I have now had the car a little over 3 years and with only 27000 miles on it, the liteny of problems I have had seem to show a serious decline on Toyota quality...
After only a few months, I noticed the rubber trim on the roof rack gutter was curling up. Then it happened on the lower corners of the windshield seals. A little epoxy did the trick but clearly the glue adhesives used were no match for tropical sunshine. Then after less than a year I noticed bubbling in the paint on the roof indicating rust underneath. Since then, there have been numerous problems - knocking from the front wheels when going around corners turned out to be related to the brake pads not being properly secured. The rear latch had to be replaced when the sensor went bad giving a constant "door open" light and pinging alert. I have already had to replace headlight and taillight bulbs - I realise these parts fail, but I have 1 2004 Highlander that has never had any problems or failures. However, the latest problem really has me concerned about the lack of Toyota quality in this vehicle - at under 27000 miles, I have a water pump failing. Most of the other stuff is annoying but minor, and for the most part, DIY-able. The water pump is not! According to one dealer, this is a 20 hour job involving completely removing the engine!! Another dealer has said it is possible to do without, but it is still a 3+ hour job. When engine components start failing, you usually think of older well worn vehicles - not a 3 year old lightly driven modern car. At this point, selling it and replacing it with a more proven and reliable vehicle is definitely on the cards. It is a shame Toyota has apparently lost their focus on quality. Interestingly, now the new Siennas have been out for a while, there is more feedback on them and the results have not been pretty. My experience seems in line with this!!!
Had my Toyota since oct 99' first off the line. I changed brakes the first time at 125K Miles. I sent a letter to Toyota TWICE in concern about the brakes lasting so long, just lucky. I've change the timing belt twice, struts, rear shocks, various sensors and lights. Even though the bumpers suck. Nothing unusual at 244K owner miles from oct 99' to aug 2013' this is the best vehicle I've owned and the least expensive in overall repairs..
See how many times A DAY you see a 2000,2001 sienna one road!
