Anyone know where I can find instruction on how to replace the Antenna Assembly and Fin on a 2021 NX 300?
I believe I am going to have to remove some interior cabin items, but I don't know how to locate the hidden clips and replace them.
My wife backed out of the garage and some how, the garage door did not open fully before she backed out of the garage.
Here is a picture of the damage:

I have the factory instructions for removal, but I do not think you will be pleased with the cost or amount of work if they are followed..
These vehicles are designed to minimize manufacturing cost and maximize repair cost . Both translate to more profit for Lexus and their dealers.

As mentioned in the message thread inked by End1ess, removing the headliner is required, for which the factory instructions have 69 separate steps (they are numbered from 1 to 69).
Post #11 in the linked message thread suggests a possible alternate approach.

Update:

I was able to access the 10 mm bolt for the Antenna through the Child Seat. I did not remove the Child Seat Hook. Once the bolt is loose, I was able to pull the antenna up through the roof just enough to disconnect the cable.
I hope someone finds this information helpful.

I wish there was a way to resize this pictures.

This is what comes with the new Fin. I used the existing Antenna assembly and just cut away the deformed plastic and it works fine for the moment. The Antenna Base is bent, so id does not sit flat on the roof. I am working to find the correct replacement Antenna Assembly.

I had the same exact thing happen to my NX 300h (2020). I took to a couple of shops and they told me it would be over a thousand dollars pre-tax for them to do it and that I should consider just doing it myself. I found this forum which led me in the right direction and used @tparrish 's very helpful photos as a guide. I was able to *very awkwardly* rig out the screw bolting the fin to the roof through the center seat hole thing but couldn't unplug the wire for the life of me and more importantly had no clue how on earth I would rebolt and rewire it in the future (the shark fin was literally hanging on by a wire).

Sooo, after scouring on Youtube I found

this video

which explains the exact process for removing enough of the headliner to access the shark fin antenna. Note that their car is an older NX 200 from 2016 but the build / instructions are the exact same as my 300h from 2020. Only ended up needing 2 tools: a 10mm socket ratchet and a plastic automotive pry bar kit from Amazon. Note you don't have to remove the "assist handles" (the grab handles over the rear door windows) as he shows in the video (in the video they are trying to remove the roof rails as well to vinyl-wrap the car which isn't necessary here).

I've also attached photos of the denting to my roof once I got the fin removed. The next step was to get the denting repaired which cost me $65 and then I rebolted the fin and sealed it up like brand new. All in I paid $77 for the new fin plus shipping from Lexus parts + $18 for the Amazon auto pry bar kit + $65 for the dent repair (which I feel like was kind of a rip off in that they literally just took a hammer and dolly for 2 minutes) for a grand total of $160 (already had a socket ratchet). Hardest part was calming my nerves that I was going to do even more damage to the car by removing panels and such (which literally every one of my family and friends told me I was going to ruin my car but I persevered lol).




The damage (once I removed the carbon fiber case which was cracked)



The denting once I removed the bolt and cord – this is why the new fin casing wouldn't sit flush


All done / good as new
