Problems with 2004 Toyota Sienna ENGINE AND ENGINE COOLING

Tl* the contact owns a 2004 toyota sienna. while driving approximately 55 mph, the contact heard a loud noise and lost steering control. the vehicle was pulled over to the side of the road and towed to the contact's residence. the vehicle was later taken to an independent mechanic where it was diagnosed that the crankshaft pulley failed and needed to be replaced. the vehicle was not diagnosed or repaired. the manufacturer was notified of the failure. the failure mileage was 96,321.

Fan belt started squealing upon engine start, took to dealer and replaced serpentine belt. several months later groaning noise started coming from engine, suspected misaligned belt or bad pulley. took vehicle to the dealer and they found wear on the exterior of the timing belt cover caused by the partial separation of the crankshaft pulley. several reports online of owners experiencing this problem with toyotas. checked with dealer and toyota customer service and they claim my vin is not covered by the recall they issued in 2011 for the very same failure i am experiencing (11v539000). how is it possible that a known defect in their vehicles can be excluded because their experts have made the determination that the "cause" was a problem at one factory or part supplier when other owners that don't fall into the specific parameters have had the very same problem and were forced to pay for repairs out of pocket? *tr

While driving there was a very loud screech from the motor, on and off, then the power steering went out, very hard to turn steering wheel, luckily i was able to force it the few miles left home. then i noticed the a/c was not cold, this was intermittent, now, no a/c at all. just hot air. this stalled of failed while in traffic, i could have had serious problems like getting hit because i could not turn the vehicle readily, or easily. *tr

There is a crack in my toyota sienna 2004 radiator and the coolant is leaking. i received a letter from toyota with information that they had received reports of cracks in radiators in 2004 and 2005 toyota siennas. as a result of these reports toyota was extending the warranty on these radiators to 6 years or 72,000 miles from the in-service date. since i noticed the crack in the radiator in my 2004 toyota sienna when it had 85,000 miles, toyota has refused to pay even a % of the cost of replacing the radiator. i bought the toyota sienna and paid the higher price because of toyota's reputation for using very high quality parts in its cars. i previously owned a toyota camry and had almost 200,000 miles on it. i did not have any problems with the radiator in my toyota camry. i called toyota's customer service department about this problem and they refused to do anything about it, saying that the car is out of the warranty period since it has 85,000 miles. clearly, the crack in my 2004 toyota sienna is directly due to the defective ...

I was driving my van when i noticed the a/c was not blowing cold air, it was more cool than cold. then it would blow hot air on occasion then it would eventually blow cold air again. eventually the air wasnt cold at all and it would constantly blow hot air. this was very unconfortable due to the fact that it was summer and i live in florida. i took it to a mechanic and he told me it was the compressor, so i had it replaced. the ac was blowing cold again, this lasted for about 12 months. the same issue started to happen again. first cool air then on and off hot air and now nothing but hot air. i took it back to my mechanic and he told me it might be the relays, i replaced both of the relays and the air is still not cold. i then found out that it was the compressor again. i cannot afford to replace the compressor and im afraid to replace it if the problem will just continue. i feel a recall for the faulty part is in store. ...

My 2004 sienna has leak in water pump with 66k mile. *tr

2004 toyota sienna - air conditioning compressor blows causing alarming noises while driving. *tr

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! *tr

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. *tr

The sliding automatic door on my 2003 toyota sienna frequently closes without warning and several times it has closed on my daughter. it is suppose to have a sensor that would prevent it from completely closing if something or someone is in the way but it doesn't work. i've had to pull my daugher way from the door as it was pressing against her. this is a real safety concern. the van has also recently begun to "automatically" lock without warning.

Engine code p2241 come on several times. toyota should cover this under emission warranty. it happen 3 times, in 07/10/2007, then in 2008 and now again. *tr

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 ...

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 ...
