Known issues
Overall
Mixed to positive sentiment, with a clear generational divide. The pre-facelift models (roughly 2019-2021) are praised for their high feature content, including ventilated seats, heated steering wheel, and rear climate controls, but are criticized for a less powerful engine and older transmission. The refreshed models (2022-2023) receive strong praise for the upgraded EA888 Evo4 engine and 7-speed DSG transmission, offering significantly improved performance (0-60 mph/0-97 km/h in approximately 5.0 seconds) and a more engaging, sporty driving character derived from the Golf R.
Best version to buy
2022-2023 SEL Premium R-Line 4Motion: This configuration combines the powerful EA888 Evo4 engine and 7-speed DSG transmission with the highest level of equipment. The 2021 model year is also noted as a "sweet spot" for maximizing feature content (ventilated seats, heated steering wheel, rear climate) before some features were reportedly deleted in later years, albeit with the older powertrain.
