Here are few i faced and most users are facing.
Passenger side seat rattling... no matter what you do, it remains the most frustrating noise. I got it replaced in warranty without any noise reduction.
Washer nozzles sprinkle water on the sunroof and mess up the whole car, even in a stand still situation. There is not solution as it's across all units.
Android unit is by far the worst i have seen in any car after civic X turbo being the worst... Lags, stucks, and does nothing good. Stock speakers are crap... even vs other craps we have in the market.
the dashboard rattles on almost all bad roads.. the average road noise in car is 85+ DB, the highest of any PKDM segment C car.
Handling is worst for the power engine delivers... we have to agree, yes its comfy but it floats, due to 176mm clearance handled purely by springs..
Now on Features, only 1 auto window and there is no back lit buttons on other doors.... even in grande X.
Mine was a brand new November 2018 FL model.
