Everything great except for the ABS

Everything great except for the ABS

Bought elite i20 asta 2 months back ... drove about 1800 km and got the first service done .. m satisfied with the car in all ways except for the ABS .. its not just my car but in general elite i20 has issues with abs .. 1. it gets activated even on small potholes and bumpy breakers making very bad grinding noise .. feels as if a iron rod is been rubbed against a concrete block ... 2. break gets stuck many a times at low speed 10-15 kph making it impossible to break unless u release and apply break again ... if u dont do this quickly u might hit some one ahead of u .. if u google u'll get many people complaining about these 2 issues and everyone got the same reply from their respective service centers tht abs noise is normal with new hyundai cars and they cannot detect any issue with the break and abs .. apart from these 2 issues everything else is just great abt the car ...
