I got mine at the end of 2018 (Dec 31 I think) so not the first batch but an earlier batch compared to the more recent Feb shipments. I have had the rack off for a month now but I will be carefully inspecting the clips when I re-install and this concern may keep me from using it at all. It would be helpful to know whether there is a correlation with the broken clips being a later batch but either way, not confidence inspiring.Sounds like you had a great time with skiing and using the roof rack. I am wondering if the affected J-bolts are from a certain batch of the roof racks. I ordered mine on 2/7 and received it on 2/11. I noticed the foot pad stickers look smaller than ones I've seen in roof rack installation videos, so I'm wondering if Tesla made some changes in the recent batch of roof rack orders which went out recently.
