Monoprice Select Mini Y Direction Movement Issues

I owned a MP Select Mini V1 for three months and had absolutely no issues until the power supply went out and I had to get a replacement unit from MP.  I received a V2 and it has had issues from the start (I am currently in the process of trying to get another replacement through MP, but I'm not sure yet if they are going to go through with it).

 

So here's the problem-when I am printing a larger object that requires the printer to move the print bed near the maximum Y location, as the printer moves the bed back, it seems that it gets stuck.  As it is stuck, it extrudes globs of material in a single location then continues the print, but because it got stuck, it is in the wrong Y position and the rest of the print is a disaster. 

 

Does anyone have any suggestions about what I should replace to fix this problem?  Any help would be appreciated.
