I have a 2014 C-Max Hybrid I bought new in 2014. It's currently sitting at Ford for the 3rd time for the same issue & they want to send it back today again un-repaired claiming the can not find an issue. The last TWO times they did this is failed again as soon as we got it home & in the immediate days following it & the dealership has been VERY unresponsive to our calls to the shop manager despite opening a case with FORD. It is driven almost every day of the week & currently has approximately 64,000 miles on it. The problem initially began about 3 months ago when in randomly began starting on engine in always first thing in the morning when I got in & showed the battery was empty (nothing was left turned on or plugged in). This was random & happened about 50% of the time, always in the am. After the 3rd time of doing this we took it in. They ran diagnostics & charged us for a battery they said was not covered under the warranty stating they could not preform diagnostics if this was not replaced -- $300 bucks down the drain-. They then claim diagnostics showed the car was 100% in working order, updated software & sent us on our way. We were not happy with this but were assured there was nothing was wrong with the car. We got it home, turned it off, turned it back on & it started on engine. Drove it right back to the dealership & they said all the mechanics had gone for the day & we would need to call the shop manager for an appointment. Took 1 month & the case from Ford for them to return our calls. In the mean time the car continued to start randomly on battery now not only in the morning but randomly during the day now about 85% of the time. Car went back a 2nd time, they ran diagnostics, checked the battery & said nothing was wrong, another call to Ford - Ford said to tell them they could consult with their technicians?? Car came back with nothing done to it. Now we are back a 3rd time & about to repeat the 2nd visit. I am at my whits end & don't know what to do or where to go. I DID love this car but am ready to trade it in for a Prius & I have been a LOYAL Ford gal for 25 years :-( Hoping SOMONE has seen this issue before.
