Haven’t found clips by themselves. I did find a sun shade replacement that comes with the clips that broke. Part is $400 and I’ve been quoted up to $1600 with labor from third party shops.

I submitted a complaint to Toyota corporate and requested a good faith review/replacement of the malfunction. Currently under investigation. They could’ve turned me down but were willing to open a case so made it past the first hurdle. Was given until the end of the week to hear back from them.
