I have a panoramic sunroof and the sunshade retracts when the switch is pressed but the shade bunches up and stops before fully retracting. It appears from online searches that it’s a well known problem with Lexus and can result in a very costly repair that’s caused in no part by the owners of the vehicles. A recall of this manufacturing defect needs to be issued.
The driver-side mirror shakes noticeably while driving making it hard to see what's on your left, specially at night. Even though I'm reporting in 2024 w/ 55k miles, I just bought this l-certified cpo Lexus 1 week ago, so the problem was likely there before. There are a couple of other signs that this car doesn't handle the south florida heat very well and my guess is the adhesive on the mirror has started to fail. There is a service notice on late model nx to address this that replaces the entire mirror assembly and they'll likely do this as well when I take it in, but it is a fairly simple issue to resolve yourself following some youtube videos even if they're not specific to this make/model.
