A/C went out April 2012. Blows hot air. According to online forums this happens a lot in Sienna's - 2004 to 2006 models. We have 5 children in the vehicle and cannot take them very far even with the windows down or they could possibly get heatstroke. They are sweated wet by the time we get from point a to point B. we open all windows and the rear ones that only open 2 inches as well. Forum link where I found this info (same issue as our Sienna) is www.toyotafans.net/2004-Sienna-ac-problems-T2523-ST20.htm -the seat belts in our Sienna lock up, found the recall on this site so will be taking it to the dealer for that. Not just the middle row seat belts though. It is rear seatbelts as well as front driver and passenger seat belts. -the tail light works when it decides to. Sometimes it is off so we get pulled over - until the police officer taps it, and it decides to come back on. On a side note - the left speaker system does not function either unless it wants to. Same as the tail light. One minute it is off (most of the time) and the next minute the sound is blaring.

On December 5, 2007, I came out of costco to find the fire department had already put out the engine fire on my 2005 Toyota Sienna - absolutely no warning. It happened after I had gone in to shop so the engine was completely off with no person in it.

Vehicle has excessive spark knock at low speeds, starting from a stop and at normal driving speed when engine is under a load. Spark knock worse when engine is warmed up and during warm weather. Changing octane level does not help spark knock. This has been happening since vehicle was bought in April 2005. Vehicle has been back to the dealer several times to try to fix the issue to no avail.
