I was driving to work when I heard a loud knocking noise in my engine shortly after beginning my trip. My vehicle then lost all acceleration power as I was making a left turn at a light. Then, the check engine and oil pressure warning lights activated simultaneously. Had the driver behind me not been maintaining a safe following distance, I certainly would have been rear-ended. After having the vehicle towed to a mechanic approved by my insurance company, I was told that the issue was possible engine failure. There were no warning lights or symptoms before this issue arose, and I still had 400 miles before I was due for another oil change.
