This morning, after having driven my 2015 C-Max Hybrid for approximately 6 months, upon attempting to start my car, the stop safely now warning popped up. The car was running in EV Mode, but would not move. I attempted to shut if off to no avail. After about 5 minutes, I could turn it off, and reattempted starting it, to get the same exact results. After about another 20 minutes, I tried again and it started fine and drove, although I worried about it and parked it, taking another car to work. Searching the internet gives me several problems that it could be and I have not tried calling my dealer to have it checked and taking it there involves a long drive. Would buying an OBD-II reader give me a better way to find out what the problem could be? Do I need a specific model of ODB reader to work with the C-Max? Any help would be greatly appreciated.
