Not sure about 2010 model but on mid 2010s this is a common issue, fixed by replacing the shift knob. My 2013 had the same issue but I didn't bother fixing it as I rarely used the manual mode. On the 2013 and similar the shift knob pulls straight up and off, but it is extremely hard to do according to others who posted her about it. If you do a search there are other threads about this.
