“Engine failure. While traveling at 75mph on the highway, the vehicle lost power and threw a check engine light. I pulled over to the side of the road and shut off the vehicle and attempted to restart it. The vehicle did not immediately restart, but did so on the second try. I drove away and approximately a mile down the road, the vehicle began to knock and make banging noises, I pulled over once again and called a tow tuck. Vehicle was later diagnosed with failed rod bearings and required a full rebuild. Vehicle had 125k miles at the time of failure.”
