Engine Belts And Pulleys problems of the 2004 Toyota Sienna

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?.

Passenger side sliding door cable snapped and will not open. Passengers can be trapped in the van and not able to get out. This is a known problem with Toyota Sienna minivans with electric doors. In addition, the motor is often known to fail. The the cable has a black sheathing that is inadequate and wears causing it to jam in the pulley and break or exposing it to later corrosion and then it will break as well. Toyota has known of this problem for years and does not issue a recall. You only need to check the Toyota forum to confirm the problem with many owners reports. Repairs run $1,200 to $2,000 at the Toyota dealer.

Tl- the contact owns a 2004 Toyota Sienna. The contact stated that while starting the engine he noticed a squeaking noise. The vehicle was taken to the dealer for diagnosis. The technician stated the crank shaft pulley had detached from the vehicle. There was a recall under NHTSA campaign number: 11v539000 (engine and engine cooling) that could have been related to the failure. The manufacturer was made aware of the failure and stated the VIN was not included in the recall. The vehicle was not repaired. The approximate failure mileage was 110,000. Da.

Complete loss of power while in motion entering freeway. Previously had noticed steering difficulty at times and engine light going on, but had always stopped after a short while. After the failure it was diagnosed as failure of crank shaft pulley. We found that Toyota had done a recall for this issue, but had not included our vehicle in the recall or notified us. Toyota denied coverage of the required repair. Driver and two small children in care at time of failure, just about to enter freeway. Over $800 in repairs.

2004 Sienna hesitates wont acell when releasing gas pedal and reapplying gas just boggs down sits there for secs. And then goes afraid of getting hit when going around turns or pulling out in front of other cars just does not respond. Toyota performed 2 bull. Updates does not fix problem at all. Feel very unsafe in this vehicle have pulled off road a couple times to avoid getting hit by other car catching up very quickly while my car does not reponed to pedal. Note have talked to numerouse other 04 Sienna owners with same complaint concerns.
