One of worst product of Hyundai

I had a issue in breaks, when I approached the dealer they said it’s manufacturing defect and also 3rd gear car vibrate like a hell. It’s can be much better for that budget feel like Maruti 800 is far better than this in terms of driving comfort too, I have sold this car 6months back since I’m not satisfied. When I did the service Hyundai dealer changed my car back number then escalated to top officials and then got replaced.
