I bought this car in September 2020 and drove it till October end with no issues. Started facing issue of vibration and engine shut off after switch to CNG. After multiple visit to service center and complaining to Hyundai, vibration issue is better but CNG remains. I have to drive 6-8 km before resolving this issue. This is my first car and I am very much shattered with the performance. If I can get my money back by returning this car, please help me. Thanks and Regards
