So i bought a brand new 2013 subaru Wrx Sti last august. It had always been a car i wanted to own so i finally order it and drove it right off the showroom floor. The car ran great no problems had the oil changed at 2500 miles like my dealer recommended. I never launched my car or anything too harsh(other than pressing the gas pedal down on the highway). I was driving down the highway friday and noticed a sound coming from the front of it, paniced i drove it home and parked it until the next day when my buddy could listen to it. i turned it on for him and the sound was even louder saturday and my buddy says you need to take it in to the dealership it sounds really bad. I took it to the dealership and the guy listens to it and does some digging around and says he believes its worse than i thought that it threw a rod bearing. Now im no mechanic or anything but why would my car do this if i havent even been that hard on it or anything? subaru of course gave me a rental car and said it could be awhile before i get to drive my car again. One of the guys at the shop said they would probably have to order a new engine and put it in. Is this a common thing for subarus or the STI's in general? im a new subaru owner so im not too familiar with everything. My car has 5800 miles on it at the moment.
