Affected Component: POWER TRAIN

Summary
Some 2020-2021 Mustang GT500 vehicles built on or before 30-June-2021 may exhibit a no crank/no start with no powertrain control module (PCM) communication condition if the oil level is approximately 1 or more quarts low and the oil life is at or less than 20%. This may be due to various parameters within the PCM. To correct the condition, follow the Service Procedure to reset and reprogram the PCM.
