I purchased a beautiful used 2013 with the panoramic roof. After a few weeks of ownership, the shade came loose from it’s moorings. I was given an estimate of $1,065 for repair, including about 800 for the part. I ordered the part for under $500 from a discount OEM supplier. I’ll DM you the address if you’re interested.
It’s due to be installed on Tuesday. I’ll let you know how it goes. I’m thinking of saving the old parts and repairing the shade myself. If I do that, I’ll probably be interested in selling the part for a good price.
