Ultrex Expert

On my 3rd trip out with my new ultrex, trolling motor function worked perfectly. Got to my first place I wanted to fish, tapped the spot-lock button and nothing. Reached down and tried to engage it with my hand, nothing. I then discovered the north button below it wasn’t working either. The trolling motor pedal and the motor worked as it should with no steering or speed issues. I’m calling Minn Kota tomorrow, just curious if any other Ultrex owners have experienced this issue? Thanks for any advise given.
