The 2022 Model 3 benefited from lithium 12V batteries, the Ryzen MCU3 processor (5× faster than MCU2), and the most refined version of the Classic generation. These cars represent the best balance of technology, reliability and value in the used Model 3 market.
2021 and early 2022 "refresh" models with heat pumps can experience a loss of heating in winter. This is often caused by faulty refrigerant pressure sensors (Recall SB-22-18-002) which can fail and prevent the compressor from operating correctly.
The front upper control arms frequently develop a loud squeaking or "old bed spring" creaking noise due to water ingress into the ball joint. This is very common in the UK due to wet weather and road salt.
Water ingress into the rear light clusters is common, often leading to visible condensation and eventual failure of the LED units.
The paint on Model 3 is known to be relatively soft, making it highly susceptible to stone chips and "sandblasting" on the rocker panels and sills.
