“The contact owns a 2005 Saturn L300. While driving approximately 40 MPH, the vehicle stalled without warning. The vehicle was taken to an independent mechanic where it was determined that the serpentine belt had fractured and entered into the engine compartment. In addition, the mechanic noticed a large hole in the engine cover, which allowed the drive belt to enter into the engine. The vehicle was not repaired. The manufacturer was made aware of the issue and referred the contact to the dealer. …”
