Caution for Hyundai Aura users and buyers

We bought this car in 2020, initially it went well but from the start we identified that when we switch from petrol to CNG it shows engine button and car slows down. We immediately rushed to workshop they mentioned that it's a system update. But now after 3 years car also started giving jerk and stopping very often. Extremely disappointed with the car Hyundai Aura performance.
