I have a sienna le 2001. 118,000 miles. We have been the only owners since we bought it. We have no perfect record of oil changes but we have done it periodically. About 3-4 months ago, it was running ok, but it blew out white-ish/ blue-ish smoke occasionally (usually when first starting, it didn't seem to make a difference if it was hot or cold). It also had little and occasional power loss when accelerating from a stop. I took it to the dealer where we bought it, and they said they just took off the top cover of the engine and it looked like it was gummed up with oil. I have changed the pcv valve, I took it to a place for an oil and oil filter change, I am concerned the damage will continue to the engine. The dealer said I need a new engine, costing around $8000. I asked a second opinion of the mechanic that has worked on our cars, and he thinks he would need to take apart the engine and figure out he problem, costing around $2000-$3000, he also mentioned the possibility of a new motor. Honestly, I do not recall receiving information about the "special policy adjustment" from toyota or dealer regarding check-replace the engines that are or could be damaged from sludge. I will appreciate your input and support.

The engine failed and had to be replaced at a cost of $5,000 due to oil sludge buildup. Traveling on I-4 from tampa to orlando the check engine light appeared then we heard a tapping from the engine,. I pulled off the road and aaa towed the vehicle and a rental car company picked us up. I had two elderly passengers (in their 80's) with walkers who had to traverse the grass along the interstate to get to the rental car and were nearly blown over by passing trucks. Toyota refused to honor a claim for repairs although they had agreed in a recent louisiana lawsuit to cover said repairs for 8 years from date of purchase. My failure was 8 years and 10 months from purchase. The sludge took much longer than 8 months to build up but toyota refused to honor their stated commitment to assist all affected by oil sludge damage (over 3,000 complaints). Their product was defective and dangerous and their denial to assist was dishonorable.

2001 toyota sienna le, purchased new, started having problems. "check engine" light came on when vehicle had approximately 25,000 plus/minus miles. Under warranty, toyota dealership replaced the oxygen sensor without a charge. However, during this process, the "beep" signal you hear when locking-unlocking the vehicle with remote key was disappeared. This is also fixed under warranty. The "check engine" light came on again when the vehicle had about 35,000 miles. Toyota dealership said it is due to a dirty vacuum hose, they cleaned it with a charge little over $100.00. The next day the "check engine" light came on again, this time the toyota dealership said they need to replace the charcoal canister (parts free, but we have to pay labor--about $100.00). This thing causes extreme mental distress, time, money, security etc.

The engine of my toyota sienna 2001 with an identified oil sludge problem seized while driving at highway speeds. Vehicle could not be controlled and my toddler threw up in fear as we tried to avoid being smashed into while the car coasted to a stop. Mechanic repeatedly said cam seized, metal filings found, and "could not think of any other reason but the sludge problem." toyota refused to repair the vehicle under unlimited mileage, 8-year warranty. Car is presently with dealer and may be examined by engineers from the federal safety agency (dealer agreed on 12/22/05). This failure was predicted by another dealer. Car always smoked--blamed on "new engine break in", "lack of maintenance", etc. Later toyota sent letter about the issue. This time dealer agrees maintenance was excellent.
