Upon inspection of the vehicle, the mechanic informed her that coolant had leaked into the oil cylinder and they referred her to a dealer for assistance. The contact then had the vehicle towed to the dealer where they diagnosed the vehicle with a defective water pump as well as engine failure. The manufacturer was also notified of the failure and stated that the failure was caused due to poor maintenance. No further assistance was provided. The vehicle had yet to be repaired and remained in the possession of the dealer. The failure mileage was approximately...
