Unless you haven't had it do it again, no, but if it has i would get it checked out.
I have a 2003 Honda Rancher ES (Electronic shift) with less than 400 miles on it. I've had it almost a year and have experienced no problems with it until now. This morning while planting food plots, it got stuck in 3rd gear and would not let me shift up or down. The shift indicator on the digital disply was continually flashing the number 3. I finally turned the key off and turned it back on. Everything worked fine then and continued to work fine. Is this something I should be concerned about?
