Hyundai Motor India — Creta break free @ 120km/hr

Address:	Guna, Madhya Pradesh, 473001

Hello Sir/Ma'am,
I purchased CRETA 1.4 BASE model on 13th August 2015. From the beginning this complaint was found in the car. As soon as the car reaches the speed of 100 to 120 km/hr on rough and patchy road, during overtaking a vehicle the brakes go free for a few seconds (3 - 5 seconds). We I have already tried to take care of this with the service centers but they are unable to solve this problem. The car has been delivered for service thrice in last 7 months. When asked for service engineering contact information, they did not provide any.
Please take care of this problem.
Regards,
Rajeev Jain
