Some 2010-2012 Fusion hybrid electric vehicles (HEV), 2010-2011 Milan HEV and 2011-2012 MKZ HEV vehicles may experience reduced electric vehicle operation and increased gasoline engine operation around 10 years of vehicle age and beyond. This may be due to software in the battery energy control module (BECM) and the powertrain control module (PCM). To correct the condition, follow the Service Procedure to reprogram the BECM and PCM.
