Some 2020-2021 Escape vehicles equipped with a HF45 transmission may exhibit a rattle noise on cold start up only when the engine is running. This noise may be more prevalent in cold weather conditions, typically at or below 0C (32’F). This may be due to the software in the secondary on-board diagnostic control module C (SOBDMC). To correct this condition, follow the Service Procedure steps to reprogram the SOBDMC.
