I suggest that you speak with Bruce C. Ertmann at Toyota. He is the one that promised to send out the 3.3 million Toyota/Lexus owner letters to those affected in the engine oil sludge case.
Sure, we know that on the first round of letters he stopped them from being sent out. The first letter was a very customer-demeaning letter that shamed the owners of these iron-clad vehicles. Then, when the second round of letters began, I learned that many Toyota owners still never got their letter! Imagine that...evidence of a problem...and no notification from Toyota! I guess now you understand why these owners all signed on to a class action lawsuit.
There are 3.3 million Toyota and Lexus vehicles included in the sludge campaign initiated by Toyota.
Unfortunately, that is NOT the true number because other models and model years are affected. Toyota has yet to acknowledge this fact.
