   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.

I have brought this into the dealer, but they said it is normal. In 30+ years of driving cars, I have never had a car mirror do this.

   When braking to a stop at low speed (stopping at stop sign or at light), then car accelerates forward even though my foot is on the brake attempting to slow the car down. This unintended acceleration is dangerous and can cause an accident.
