 The transmission never shifted into Drive properly. There was a delay in shifting then the transmission would slam into Drive.  Mechanics said it needed a PCM software update. The PCM and the TCM software was updated and it didnt change anything. This started occurring within one month of vehicle purchase (New). This is a known problem and will eventually lead to a Valve Body Replacement or full transmission rebuild which would be very expensive. There was constant problems with the software. The GPS was often off by several hundred feet. It would show you driving down the road except the GPS line of travel would be off to the left of the actual line of travel. The car often refused to start even with a full battery, constantly acting like it was in remote start mode where the engine is running but the power is off. Except the engine and power would both be off but the car "brain" would think differently. Because many of the systems require power to b in sleep mode, many times the battery would be dead after just a couple of hours sitting. Diagnosing a parasitic drain showed the drain was normal, but the battery that came stock with the car was not enough to stay charged with the parasitic draw that is in fact normal. Battery replacement was mandatory for a new car and should not have been. But it did fix the problem. There are many videos online with people with the same problem with the Fusion and Focus.  Sitting still the glass in the sunroof cracked. The temperature was in the 70's and the car was not moving with no trees, other cars or anything else around. It simply cracked. The glass in these roofs is made to shatter. Others have complained about the same problem. This occured within about two months of purchasing the vehicle. As I was told, "It isn't Fords problem". Well it is now since we went back to Kia. After buying three new trucks and three new cars in five years we thought we would give Ford a try since we did like the Fusion Titanium when we test drove. However, that experience with Ford, attitudes in service whenever we brought it in for service and the complete 180 from our experience with Kia had us completely ignore Ford when we were looking for a new car. Bottom line. Thirty seven years of car buying and ovr 20 new cars and 10 new trucks that was our first Ford and it will be our last Ford.
