I have the 27mm lens, and I too started to see these 'Turn off and on ..." type of problems. This was after I fitted a 37 to 58 mm filter thread converter plus a 58mm uv filter. The reason for me doing this was no standardise the filter threads on all my lenses. It seems to me from other's contributions that the tiny motor struggles when there is too much excess weight it has to move, and malfunctions. I took the filter/converter off, and it was happy again.
