I took my 2014 Zero S in to my dealer for its 600 mile inspection today and on the way there I noticed (for the first time) that the instrument display had a large, but somewhat indistinct, "V" rainbow covering most of the panel. It shows up both when the bike is on and when it is off. I had the shop technician look at it and he agreed that it wasn't just my eyes. So I had them make a note of that issue on the work order. While it is noticeable, it is not interfering with viewing the display. But I sure am going to keep an eye on it to see if it gets any worse. Today it was dry and sunny with the morning temperature at 50 degrees F. I sure hope this isn't a design or component selection issue.
The inspection cost me $100, which I believe is the shop's minimum labor charge. Other than checking things over I was told that the only adjustment performed was adjusting the belt tension.
