I recently experienced what a lot of other 2004 TSX owners on this forum have experienced in which my piston rings failed, causing oil to burn at an extraordinary rate. After about 4k miles between oil changes, and only 80k miles total on the engine, my engine seized up and I needed to replace my engine. I complained to Acura USA, that this shouldn't have happened given the mileage on my vehicle (80K) and maintenance records (everything done at Acura dealership). They offered to pay for 25% of the repair cost for a brand new engine. Clearly this has been a problem with other 2004 TSX owners and Acura USA has accepted some blame in that they're offering me some repair assistance. I was just wondering if anyone has heard of a class action lawsuit for this issue. The Acura maintenance shop assured me that the new engine I will be receiving will not have the same issue as the 2004 engine in my TSX.
