Gasoline Engine Problems of Toyota Sienna - part 2

Engine sludged at 35000 miles, and again at 79000 miles. Warranty coverage was denied even though we presented evidence of regular maintenance. We were recently offered reimbursement for the first repair by Toyota in the amount of $2300. They denied reimbursement on the second repair in the amount of $7100 because the vehicle was no longer under warranty. The engine has sludged twice in spite of regular oil changes. Total repair and incidental costs have exceeded $10,000.

Accepted for arbitration by wa state atty general.

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.

Consumer states that an indicator illuminated stating that there was an engine malfunction with transmission and stated consumer needed to stop driving immediately, dealer replaced the vehicle with a new one.

Our dealership has one person doing the work which three did at my girlfriend's old dealership; they keep telling us to "keep a log" of problems. She went in and told them the car had to be fixed; they said okay, and it sat for a week while they ordered parts which we thought they already would have in, due to our previous/numerous complaints. So now it's going _back_ in Monday morning, although they continue to insist they don't think they have parts for the inside door locks; she's going to ask them about it. It is very frustrating to have the dealership say "we don't have the parts" and/or "keep a log" when Toyota must have the parts -- it's their vehicle!! -- and we don't need to. 1 qt. Of oil per every 100 miles travelled for the last six-twelve months is insane. And Toyota continues to insist that it's from "lack of maintenance" when the oil changes were done primarily at dealerships in mi and FL . . . Does not sit well with me. Please contact me any developments pertaining to the Sienna . . . Thanks!! -- george seger, (231) 932-9501.
