- A fairly reliable engine unless it has been tuned;
- Watch fuel quality: there are already cases of pistons destroyed by detonation, and the plasma-sprayed cylinder walls suffer from bad petrol;
- Change the oil as often as possible: turbocharger life depends heavily on it;
- Components of the 48-volt mild hybrid system cause a lot of trouble.
