the car has abruptly applied braking while driving. I took the car to get checked after that and i was told that there was nothing wrong except that the pads will need to be change sooner than later. I mechanic did tell me that it could be a safety issue because it was an uncontrollable. I than took the car to the Hyundai dealer for them to diagnose the car. They proposed that i change everything, including the brake pedal, which to me, sounded very fishy. One week ago, while driving, the car suddenly jammed on the brakes again. This particular time, it was also emitting smoke, either from the front or the bottom.
