The contact owns a 2016 Ford Fusion. The contact stated that while the vehicle was stopped, the engine started to rev. There was no warning light illuminated. The contact drove into a gas station and the vehicle shut off while parking the vehicle. The contact’s brother arrived at the scene and restarted the vehicle; however, the revving persisted. The contact was informed by another owner of a similar vehicle that the failure was related to the fuel system. The vehicle continued to rev, and the contact opened the fuel tank which allowed fumes and air pressure to be released from the gas tank. The vehicle resumed normal operation while the contact drove home; however, the failure returned the next time the contact drove the vehicle. The vehicle was taken to an independent mechanic where a diagnostic code reader showed a defect with the evaporative canister vent solenoid. The vehicle was advised to stop driving the vehicle and the vehicle was towed back to the residence. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 158,000.
