Key battery drain is a thing if the key is kept within 6 feet of the vehicle. My original fob battery lasted about 1 year. Second fob was only used a couple of times and was still good after ~2 years. (MY2021 4/21 production)
Have not heard good things about clearplex but I have STEK and it works well. One thing you must do with it is use silicone wiper blades. OE/pure rubber blades streak the film.
Heads up: race tex/alcantra steering wheels aren't awesome after a while of daily use. Some can clean up with HI-TECH extra foamy but with heavy use they look crappy. Of course one can just use driving gloves every time they drive. ;)
If if your drive unit is faulty like mine was on my 21 RWD you'll be glad you have extended warranty. It's ~$40K to replace. Replaced and first gear noise came back after a short while. I sold the car a couple months ago due to concern of repair costs outside of warranty.
Sold my 21 RWD a couple months ago. 2 years in and with no drive unit issue resolution from PCNA it had to go. My concern was excessive $ in repairs post warranty.
I had no software issues - it's the drive unit/transmission. It's not limited to early models, I know of 21 and 22 owners complaining of the same problem that plagued(s) mine - 1st gear whine.
Similar feelings for me and sold mine a couple months ago. After my troubles PCNA would not do anything for me and my concern was big $ failures post warranty.
None. My 2021 still smells new. The key to keeping new car/natural smell is: NO food, no drinks, no pets, no dirty/smelly clothing, no foreign heavy odor matter inside the cabin. Whenever I would have fresh food or take-out it always goes in one of the trunks - preferably the front.
It's more pronounced in sport since first gear is held longer and first gear is the problem. Mine was very noisy 50-60mph - especially when deceleration with regen/recoup on.
