Some of the version 1s developed an internal ribbon cable issue that was expensive to have Canon repair. There were a zillion of these lenses sold, and probably only a small percentage developed the issue, but it is a known problem. i’ve had my version 1 for 4-5 years with no issue.
I had read this as well, however mine didn't suffer from that, just lens creep. Mine was also 6-7 years old and after having read and researched the reviews on version II, I simply upgraded.
