Consumer Description

I turned on my minivan to drive my kids to school when I heard a sudden loud metal shredding/knocking and shut my van off. All maintenance was performed regularly on the van and no lights were on. I have a hole in my engine block now caused by a thrown rod, and no mechanic can explain why this happened. Oil was in good condition, and nothing indicated this should have happened.
