| Description of the problem | I have 2 different complaints. Driver side seat heater burned legs of 3 different drivers before complete failure. Heat was not adjustable. Driver and passenger heaters stopped working at same time. Took to dealer, recommended new heating element ($1000+). Opted not to fix. 2nd complaint, check engine, vsc, and trac off lights illuminated. The van has been sent to the dealer on at least 3 occasions. Gas cap has been replaced several times, spark plugs changed. Will go off for brief periods, but always to return. This has been going on for at least 30,000 miles. I could live with the check engine light on, but if the other lights are illuminated, that indicates these components are not working-kind of important-skid control & traction control!! There are many complaints out there on blogs, doesn't look like anyone has filed any reports with your office regarding this same problem, which is too bad because it's obviously a problem not with just sienna but several other models as well. Extremely frustrating when even the dealer can't determine what the problem really is!! We purchased this vehicle because of the safety features. Not so sure about it if their safety features malfunction! |
