The line #24, which is one of the two lines to the secondary cylinder just over the passenger side window cracked as a result of repeated stress from opening and closing over 11 years (about 2,000 operations I would guess). The secondary cylinder lines (#21, 22, 23 and 24) are the ones under the most stress on the system.

They are the most prone to fail because of the sharp bend they experience as the top closes. When you watch how the top folds down you can see those lines bend. There is a one particular zip tie holding those lines in place which adds to that stress. That is where mine failed.

Luckily those lines are fairly easy to replace. They don't require removing any part of the top frame or cover at all.

Regarding the Bungee cords, even after 11 years they seem to be doing OK.
