I pulled over to the side of the freeway and opened my hood and saw my harmonic balancer/pulley laying on my skid plate as well as a broken bolt. I researched it and found out it happens alot on the vehicle and that its very common. I use the vehicle to drive to school and to work never abuse it and now I am stuck paying more then I bought the car for.
