I'm not sure why anyone expected a new facelift would improve sales. It's clear the overall decline is associated with Musk going full mask-off fascist, given this, driving around in a car that looks unlike any previous Model Y just makes it completely obvious that you knew this and decided to buy one anyway. If they want to bolster sales, maybe they should have kept producing the pre-facelifted versions for a while.
Full disclosure, I used to own a Model 3. I had it for 5 years and was generally very happy with it - it was a great daily driver, cost very little to run and maintain, and (aside from a few issues later in my ownership, which was one of the reasons I decided to sell it) in general it was very easy to live with.
There are clearly some very skilled engineers at Tesla who know how to build a great product. It is a shame their efforts are being undermined by a fascist lunatic with a narcissist complex.
The main issue was a catastrophic failure of the VC_FRONT module which is one of the critical onboard computers that manages things like the 12v battery and low voltage power distribution (basically a "smart" fuse box). Without it the car is bricked and cannot be driven.
That took several weeks and some back and forth around the extended warranty to resolve, and then even after that module was replaced, on my first drive after the repair it went straight into limp mode and then spent another week at the service centre having that diagnosed.
During this time I decided it might be time to start looking for a new car, ended up selling it a few months later and took delivery of a new Polestar 2.
