Purchased a C-max SEL(302a) 2013 on April 7 of 2014 (built on Nov 24, 3013). Mon, May 12, went out to start car and everything was dead. Called Ford and got a jump start. Called the dealer I got it from and they said to get it in to service ASAP to have it checked out. Service said they could get the battery to fail for them also and they ordered a new battery. Did not have one in stock and will have it installed on Monday. Have had a problem with the radio not coming on using the dash button, since the car was new. This usually happens first time I use the car for that day. Have to go through voice command to get it to work. Many times after that, on same trip, the dash button might work. The Service manager said the radio worked fine for him. This is because I had had it on when I drove there. Service does not seem to believe about the radio unless he can get it to not work also. When I drive it in to get a new battery, I will be sure to not turn the radio on so they can become believers. I know this is very minor, but wonder if it could be connected to the battery problem, somehow. Anyway after reading all these posts about the battery problem, I am feeling mighty discouraged about the battery being the 'final" fix. Has anyone had the battery problem fixed with just a change of batteries? My husband and I are in our 70's and not "handy" with cars, so all the information from these posts has helped big time.
