2001 Toyota Sienna Problems
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.
Sludge can build up in the engine because Toyota did not recommend frequent enough oil changes. Lexus will sometimes offer a discount on cleaning the engine if necessary. Owners who changed their oil every 3,000 miles did not experience these problems. This sludge build up can lead to excessive oil consumption.

2001 Toyota Sienna Reviews
Best car I've ever owned. Just went over 200,000 miles last week. No problems other than standard maintenance. ...although I think the air compressor is starting to go out. Also, have a check engine light that is due to an improper setting - says it's the cadalatyc converter, but have been told it's fine. I also agree that the door handles are made of cheap plastic. Just hit a deer 2 weeks ago at 60 MPH, with minimal damage. 3rd deer I've hit. First two deer just cracked the plastic grill. Most recent deer hit did more damage, but only body damage. My biggest complaint about this car is it's turning radius. It can feel like parking the Queen Mary sometimes. Still love this car, and think it can probably make it easily to 300,000 miles. Engine is great. Transmission is great. Very comfortable on long road trips.
Most reliable vehicle that we have ever owned. Runs smooth and quiet. Very versatile carrying people and things. Have 84,000 miles at almost 8 years and replaced a single light bulb other than tires, brakes and a battery.
