My 2015 STI suffered
My 2015 STI suffered connecting rod #2 bearing failure after 3 months of new ownership and no mods. Subaru replaced the Long block under warranty. There is currently a class action lawsuit for 2015+ STI owners who had similar bearing failures and lost money when they paid for repair at dealerships or traded in the car without fixing it. The issue was real. Used buyers should be wary of this model range if the engine has not yet been rebuilt with upgraded aftermarket bearings.
