At 107,000 miles while driving the motor just cut off. Then would not start. I always have changed the oil at every 3000 miles. Now my mechanic says that the camshaft broke. There can be no other answer than that this engine was a sludge defective motor from the manufacturer.
Engine sludge @ 25000, oil changed every 3000-5000 miles, Toyota not honoring warranty, contacted attorney.
Another Sienna sludge victim. Toyota answers rehearsed. Did not even question owner about maintenance history; therefore, obviously irrelevant to them. Contacting attorney to inquire about class action lawsuit. No safety defect listed in summary.
Consumer was pulling up in driveway and noticed that there was white smoke coming from underneath of vehicle. She took it to gas station, and mechanic told her that oil was less than three quarts low. Dealership was aware of problem.
The engine produce clouds of grey/white smoke for 5 to 10 seconds after a cold start up. Upon checking, found the engine oil 1. 5 to 2 quarts low. Added oil and drove vehicle for a few days with similar symptoms - smoke after cold start of after being parked for more than 2 hours. On 7/3/01 brought the car in to dealer for diagnosis. The dealer looked under only one camshaft cover, found evidence of sludge and - even though I had receipts and proof of three prir oil & filter changes at 5800, 11000, and 16595 miles - declared my engine warranty null & void and made no other attempt to diagnose the problem. I am currently trying to get toyoata to honor my warranty and to have another dealer or mechanic diagnose the problem. However, research on the web indicates that Toyota is stonewalling many customer like myself.
Transmission went out at 75 mph/tachometer went to zero, and engine kept running. Dealer informed consumer that she was # 49 on waiting list for a transmission which was on back order.
Have been told I have sludge build up in my engine due to lack of maintanance. I have receipts for 3 oil changes in the first 19000 miles, but they then tell me it must have been inferior oil. Have found this to be problem with people nation wide, and Toyota will not stand behind its warranty. There is no way that this problem has been caused solely due to a lack of maintanance to all the people having the same problem. Toyota wants to rebuild the engine on a one year old van with 19000 miles for $2200, though it was properly maintained. Will not accept receipts for service done as proof of maintanance. What else are we supposed to have to ensure proof?.
No summary listed for above vehicle.
Told by Toyota that sludge in the engine is our fault despite regular oil changes. We don't have all our recepts but changed the oil at least 4 times since we owned the car. Impossible to believe that we were neglectful, especially when I am seeing so many other cases with the same thing happening. There needs to be an investigation here soon.
We have to wait for the part(s) because every Sienna has the same problem.
Several t/c defects on the 2000 Toyota Siennas. . . Why arent they not being recalled by the manufacturer?.
Engine sludged at 11,105 miles in spite of correct oil changes. Tires need replacement at 13,100 miles.
While driving engine just all of a sudden lost power and vehicle started to slow down in the middle of traffic, possible engine or electrical malfunction.
Sludge problem started at 11111 miles - also tires needed realignment and replacement at only 13115 miles. The van blows blue smoke upon startup. We have been blamed for the sludge problem. We have receipts for oil changes and have done some ourselves. Now we are told, by the service dpt. That we have to change our oil every 1000 miles and check the oil every two days. Been doing a lot of reading on this, and have talked to others - this is a defect in the Sienna and other cars, Lexus being one. Was told the engine would seize eventually and I would have to put out $5000 - $8000 for a new one. This isn't covered under warranty either.
Engine sludged at 29,080 miles . All oil changes were performed as required per warranty maintenance agreement. An entire engine overhaul is now required.
I believe engine sludge complaints are ficticious.
