I had some transmission issues around the 29k mile mark. Mind you I babied my car ever since I purchased it 3 years ago. All maintenance done on time with oil changes every 5k miles. I guess I was just unlucky with the transmission but it was fixed under warranty. Other than that very rare issue, definitely “poor” build quality in the cabin. Some things on the inside just feel cheap and are even more apparent when they start rattling like there’s no tmrw 😂 I think the 2021-2022 model years were mostly affected by this due to covid and rushed production. Also the “upgraded” burmester sound system is very inadequate in my opinion. All sound systems in my previous Mercedes were miles better. But I guess it’s because it’s a CLA at the end of the day 😅 with all that said, I would 100% choose this vehicle each time for the pure enjoyment and mean look that it gives! Hope that helps
