-Stock 2014 wrx
-failed rod bearing
-warranty to rescue
Took it in this morning after an awful tapping started yesterday. Got a call back this afternoon that it was indeed rod bearing #4, and they'll be replacing short block and at least one head.
Completely stock (except axle back muffler delete) with 12,500 ish miles. They asked for oil chance receipts (which I had in glovebox, 4000 and 9100miles) and asked if I ever had a tune on it (which I didn't). They assured me that they can tell if ecu was tuned, but I have nothing to hide. Glad I didn't get the accessport I so wanted to get! Anyways, manager said everything looks good for warranty covering obviously.
Mind is just blown what caused it. I don't drive like a grandma, but I'm not an idiot either. This isn't common is it? Factory defect?
