A hairline crack from the engine oil drain plug causing leaking oil. This is a very common issue for this engine. Mine was present when the car was new. My local dealer claimed my car has run over something, which never happened. No dent or damages on the oil pan, just crack on the side of pan. This is very common issue for this engine. Low engine oil level will cause engine failure.
