While I doubt this is relevant to forum members at this time, I thought it was worth documenting: SSM 44252 - Hybrids In Taxi Service - HF35 Transmission Bearing Noise Some 2013 C-MAX Hybrid and 2013-2014 Fusion Hybrid vehicles operating in taxi service may exhibit a metal-on-metal scraping-type sound from the transmission. This noise will be present in all gear ranges including neutral when the vehicle is moving, but will not be present when the vehicle is stationary or in park. The current transmission assembly (7000) service parts incorporate design improvements to enhance durability under the unique operating conditions of taxi service.
