Some 2016-2018 Model Year Focus RS may exhibit inaccurate Outside Air Temperature(OAT) readings with intermittent Air Conditioning(A/C) function. Instrument cluster will display 0 degrees F(-18 degrees C) until the vehicle is driven above 20-30 mph for minimum of 1 minute. Concern can occur when engine is running(Key On Engine Running-KOER) and ignition is cycled Off and On again within 1 second. Do not replace Powertrain Control Module(PCM) or ambient air temperature sensor for concern. Sensor is contained within the right hand outside mirror, and is not serviceable separately . Engineering is currently investigating. To assist with the investigation use Report A Vehicle Concern link at the bottom of the Oasis report and submit a Global Concern Report (GCR). Continue to monitor OASIS for future updates.
