Egads! Hadn't thought to check this thread in quite some time and logged into TMC by chance today...
I have not checked my clips to see if still intact - I just completed a 1,000 km road trip on the weekend and probably have about 5 - 6,000 km of highway driving with the pod installed (though mostly secondary highway, 100 km/h or slower). I'll give my rack a shake when I go to the car in the next few minutes.
I did a
consumption comparison test New Year's day, which involved taking off the rack and re-installing it - at that time, I used a kitchen scale and some maths to determine 4 Nm. That was quite a bit tighter than I initially installed it at, and I definitely would not have felt comfortable going to 8 Nm.
Edit: just finished reading the other replies to this thread and I'm concerned enough that I'm going to remove the roof box and just leave the naked rack on for the moment until Tesla gives an official response to this. Those photos of snapped hooks looks like cheap casting. I now want something milled or forged, gee whiz! While they are at it, they can fix the stupid design of using an Allen nut; should just be a 'regular' hex nut with a special notch in it for the locking mechanism. I'll be sending them that feedback as well in my email.
