Reply to "Toyota Engine Oil Sludge/Failure"

Where to find information on the Toyota engine sludge problem:

Here you can find announcement of sludge program, copy of the letter that was to be sent to 3.3 million owners, and acknowledgement by Toyota that this is just an issue with two specific Toyota engine designs. Toyota says it is not a design problem, but an owner maintenance issue, yet limits the policy to two specific engines over a given range of time.

The information on this site is not readily available except to mechanics, however, one of their announcements addresses the problem. In this announcement they discuss the problem of sludge in properly maintained engines (something that Toyota says is an impossibility).

This government-run web site includes owners’ report of sludge engine failures by year and by auto make and model. Search under “Problems and Issues” heading. NHTSA opened an investigation into the sludge problem in 2002 but closed the investigation in a matter of a few months because of Toyota’s announcement of the sludge policy.

MSN Autos site:

The above link is for the Avalon, but all the models covered by the sludge policy are reported to have significant engine problems. These ratings are based on reports from independent garages (not ones that are manufacturer affiliated) so they give an unbiased picture of problems that these garages see in vehicles.
