Ugh. My wife's 2014 Ford CMAX just started making this noise and it is getting louder. A call to the dealer told us the power train was out of warranty at 5/60k. And becasue we bought the car used at Carmax it wasn;t covered to 100k like some. So now we are facing a $4000+ repair of the transmission of a car that doesn't even have 100k on the clock. I'm taking it into the local dealer here in Durham to see if I can shame them into calling ford to try to do something for us. So far the climate control has broken too about 3 years ago so the car has no heat in the winter when my wife drives it in electric mode. (she lives very close to work and she plugs it in every night). WE took it to the dealer for that and that was going to cost about $2000 and they would have to replace the whol climate control module. It was out of warranty then. So far this car has been a huge lemon!
