Thanks for the response guys.
Well its a 2007 IS250, I bought it second hand.
It has 140000km's on the clock, which is roughly 90 000 miles
The clutch was slipping when I bought the car and the dealer replaced it, along with the flywheel and throw out bearing with what he said was original Lexus parts(Dealer being Toyota), and since he did that replacement I only did about 1000 miles, then this happened.
I live in South Africa and the law here states that ALL "defects" shall be covered by warranty for 6 months from purchase date, except for "wear" items, such as clutch, brakes, battery etc.
i.e. All I need to know is if a broken bellhousing can be classified as "wear", to me it seems like it is a defect.
