End of March 2019 after driving home from work on a Friday evening the car smelled like exhaust fumes (rotten eggs) when I parked the car in the garage. I called dealer and made an appointment to take the car in. Over the weekend both inside and outside the car the smell was terrible. Took car to Ford dealer for repair. They suggested I needed a new battery (9 months old battery - was told battery causing smell). Picked up car and drove home. Once again upon parking car still smelled like exhaust. Car was returned to dealer. Dealer replaced pcv valve. Picked up car - drove home - car still smells like exhaust fumes. Car has gone into dealer 4 times for same problem. Can no longer park car inside of garage at home due to exhaust smell and potential safety issues. Dealer says they have done everything pursuant to Ford's instruction and their hands are tied. Dealer admits the car smells of exhaust fumes outside of car. Inside the car I am keeping the recycled air on to try to prevent the exhaust from coming in the car. Car needs to be fixed by Ford as the exhaust smell is a safety hazard and should not be happening to a 3 yr. Old car.
