2004 Toyota Sienna. Original radiator replaced due to leak @ 21K miles. Radiator replaced a second time due to leaks at top L & R sides, near end tanks @ 80K miles. Radiator is now in need of another replacement @130K miles due to leaks at the same location. All radiators have been replaced by Toyota dealer.
Engine overheated on numerous occasions, slow loss of radiator coolant noted, and 2 engine thermostats replaced before cracked radiator was discovered. While owner was investigating problem, it was discovered that Toyota issued a couple of years ago a tsb and a limited warranty extension to replace radiators from this year (2004) and the next (2005) of the Sienna van. However, we have been only owner of this van and have received every other notice from Toyota regarding this model year of van including the bad door hinges (replaced under warranty), gas struts on rear hatch (replaced under warranty), and bad seat belt bezel (replaced under warranty) - but we never received any notice of the radiator issue - our radiator is now damaged beyond repair and needs replacement and Toyota will not replace even though this is apparently a well known issue at Toyota. There should be a full recall on this item given the amount of known bad radiators out there. This is a safety issue as the radiator is prone to sudden and catastrophic failure. The only known repair is to replace the radiator. There is extensive online documentation of this issue - but Toyota continues to stonewall most owners on this problem due to the expense (this is much more expensive to fix than the bad hinge, gas strut, and seat belt bezel that did have safety bulletins issued on them. www.carcomplaints.com/Toyota/Sienna/2004/tsbs.shtmlwww.canadiandriver.com/forum/index.php"topic=58487.0 www.edmunds.com/maintenance/recalltsb.html?type=tsb&styleid=100458140&zip=#18 www-ODI.NHTSA.dot.gov/cars/problems/tsb/tsbresults_drilldown.cfm?start=1&searchtype=drilldown&type=vehicle&year=2005&make=Toyota&model=Sienna&&typenum=1&submit=retrieve+recalls&printversion=yes townhall-talk.edmunds.com/webx"ed_searchresults@@.F0B4803!keywords=allin%3amsgtext%20limit%3A.F0B4803%20radiator&count=20&skip=20.

My air conditioning failed on my Sienna Toyota van. I had my mechanic unplug it. I did not have any damage but can no longer use ac. On line, I found many other Sienna 2004 owners with similar complaints. Some had cars stopping. Toyota never issued a recall but did a bulletin. The cost is tremendous to fix.
The air conditioning in our 2004 Toyota Sienna le stopped blowing cold air at 75,000 miles. It sometimes remains cold for a minute or so and then goes right back to just warm air. It occurs every time the car is started.
Check engine light came on in 2004 Sienna le, called dealership for appt, the next day, the air conditioning went out. I live in phoenix, AZ, where it is routinely 115 in the summer. Took car van to dealership where price to fix is $4200. Compressor exploded and sent shards of metal throughout entire A/C system. Toyota is aware of this problem, as posted in their tsb AC003-05, but refuses to cover their defect under a recall as it's not life-threatening. Let me tell you, riding in a car for any length of time in 115 degree weather is life-threatening. A/C is not a luxury in AZ; it is necessary for survival. Upon contacting Toyota customer service, they deny any culpability; however, there are plenty of forums, including toyotanation.com, in which people have routinely had this problem with this vehicle. Would like Toyota to issue a recall for their defect and take care of their customers. They are aware of the problem and to deem it non-life-threatening is a mistake. Most people who own mini-vans are transporting children and it doesn't take much for children to overheat in a non-air conditioned car, not to mention the mild heat exhaustion that comes from being in the car for 15 minutes. Car is still not fixed due to exorbitant cost and it is well over 100 here still in September.
I bought a 2004 Toyota Sienna ce in ottawa, Ontario, Canada, from a dealer, new, off the lot in August 2004. By the first winter, both back sliding doors would freeze shut, especially the passenger side, and would not open until the vehicle got really hot inside. The dealer had no solution, offered no solution. In addition, by the second year we had three radiators installed, and had both front doors repaired for rusting under a general recall. Also, the rear fan has been going on and off, even with the switch in the "off" position. We have taken this issue to the dealer many times, but they do not have an answer, nor a strategy to figure out why it does this. Finally, this vehicle has rattled inside from day one and is unpleasant to drive. I find the Toyota dealers not interested in you once you buy the car, but after three years to the day the called me wanting to know if I'd buy a new one. I will not buy another Toyota.
