I had the same problem. I found that da.plot.pcolormesh('lon', 'lat', shading='gouraud', infer_intervals=False) does work. Would be nice if shading='gouraud' worked by default though.

I guess the problem is that 'gouraud' needs the coordinate positions at the grid points, and I assume infer_intervals=True is creating coordinate values at the grid-cell corners (so an n x m DataArray is plotted using coordinates with lengh (n+1) and (m+1). I haven't looked into what infer_intervals actually does though. Would it be safe to just turn it off if shading='gouraud' is used?
