I just picked mine up last week (built in May). I went through a 4 page PDI checklist I put together. I couldn't find any major issues, nor nothing even minor. I had an MY Performance (aka MYP) on order but changed it about 2 weeks after ordering to go with the long range (MY LR) version. There are some good thread to compare the real world differences.
We got rid of an Acura RDX Advance version (latest gen) for the MY LR. Prior to that we had an MDX as well. I was also considering the new 2022 MDX. I can tell you some things I hated about the 10 speed transmission Acura put in the RDX and seems similar to the one now in the MDX. There is a lot of lag before you get full power off the line. It seems to wait a half second before you get full power (like they were trying to keep the torque from killing the tranny) If you take off, and then ease up, and then accelerate again, there is what seems like a massive delay ALL the time. Also that POS trackpad for the infotainment system should be thrown away. After 2 years with it on my RDX, I never ever was happy with it. Since there is no touch screen, you are stuck with it. The latest MDX has it as well.
While this is subjective, the Acura has a more premium feel inside than the MY. At the same time, it seems overly busy too. The leather is far better on the Acura than the MY but by comparison it isn't as good as that on my MB or past Audis.
I would encourage you to conider another option than the MYP. The 21" wheels are heavy and curb rash magnets. Many people try and resell them and go with something else. That was my plan originally. After some research here, I found there is a potentially a better option than the MYP depending on your needs. That is to go with the MY LR and acceleration boost after you buy it.
Tesla has not made it easy to compare the acceleration times between the MYP and MY LR. Basically if you were to use the same methodology, they are closer in acceleration that it seems at first glance. From a roll they are much closer than you would think. Adding acceleration boost (a 2k option after you buy) knocks .6 seconds off the 0-60 time. Using the same standard of measuring, that puts the MYP at about 3.8 seconds 0-60 vs about 4.2. From a roll they are going to be very close.
I can say while I appreciated my Acuras, after just a week with my MY LR, I couldn't go back. Even the slow version is so much quicker than any of the Acura SUVs and very good space utilization, I don't think I could go back. One area I liked better on my RDX was the electronically adjustable suspension. It was far better than the suspension on the MYP. Tesla still has a long way to go on the MY and M3 to get their suspension up to the standards of the rest of the class. You do have an option though to buy aftermarket coilovers to improve that.
In summary, I'd say don't worry too much about the build quality. I found a good SA who I trust here and he said he hasn't seen any major issues pretty much since the updated 2021s came out. He had no reason to lie to me as I'd already taken delivery of the car. He had been very helpful in smoothing out some of the big bumps I had along the way. I am not the ultimate Tesla fanboi but I can say so far the car was worth the wait.
