Engine Failure problems of the 2002 Toyota Highlander

I was driving my 2002 Toyota Highlander on the highway and was accelerating to pass a car when I heard a loud nosie coming from the engine area, all the lights on my dash came on and my car stalled. I struggled without the power steering and brakes to get my car over 2 lanes of fast moving traffic and get it onto the exit ramp. My auto had drastically slowed due to engine not working and I was almost hit several times as cars flew around and past me. I finally manage to get it off the highway and into a safe spot, but it was extremely difficult because I had lost all power and had no power steering or power brakes. I had it towed to the dealer. I am only the second owner of this vehicle and I know the original owner and he took very good care of this car doing all the maintenance himself and using only Toyota parts. The dealer says my engine is ruined but he never mentioned anything about the problems they have had with these engines and sludge and engine failure. The original owner says he never received anything from Toyota about the class action lawsuit nor any of the fixes for the sludge/engine failure problem. I could have been killed and am lucky I was not. Toyota should have recalled all these engines and fixed or replaced them instead of just secretly fixing them, only when forced to by the customer for only 8 years. Fact is, if the orig owner hadn't babied the car, the engine would have gone much sooner. So because he took good care of it, I am s-o-l because the 8 year extended warranty is up. I guess the real truth is that Toyota make its its cars to last longer than 8 years.
