Some 2016 Fusion and Escape vehicles equipped with 2.5L engine may experience a delayed engagement/shudder during a drive to reverse shift. This condition occurs when the throttle is applied during reverse engagement. Reprogram the powertrain control module (PCM) to the latest calibration using IDS release 102.02 or higher. Make sure you are connected to the internet when entering module programming to obtain the latest updates. Calibration files may also be obtained at www.motorcraftservice.com.
