Do you have the Hotwire for it? Updated recently? If it has not been updated that is one thing you can do to make sure every operation is working its best. Aside from that it could be alot of things. Your best bet is to read thru one of the official RS pages under electric on or off road and see if anyone else has had the same issue, or call or email Tekin. They should be more than willing to help you get it working to your satisfaction.
