Machan reason for honda dual clutch issue is, as one of the member mentioned here, it is a dry clutch. Not only vezel most of the Hyundai international versions has this same clutch unit and if you sufr youtube you can find the reason for the issue..
What happened in there is a synthetic liquid to maintain the heat of the clutch unit and it get weperized as time goes. Since vezel is originaly made for japan they recommend to change the duel clutch oil every 40000KM.
But this milage limit valid only for japapn. Sri lanka is a tropical country and due to that the liquid get vaparized more frequently. Few months back stafford was telling to replace the same oil every 20000KM.
What i recommend is change this duel clutch oil every service (5000KM) it will cost you aditional 3000LKR but way more cheaper than changing the whole clutch pack for 5laks
