I took my 2012 fusion to the dealer with the tsb202142 (that they never heard about) for the Reduced electric vehicle Operation . They say they reset the pcm and becm. When i got the vehicle back it was like new again. But sadly it didn't stick. A day later it was back to not staying in ev mode. Anyone else that has taken their car to the dealership for this have this problem or did it work for you?
