Vehicle brakes sound and feel rough when pressing them. And when backing up the vehicle spotted another car turning in and hit brakes automatically. Car jerked hard as if I hit something. Very rough. Made a scrubbing sound. Does the same when pressing the parking button. It perks and makes the scrubbing sound. Just purchased Vehicle 2weeks ago. No inspection on it yet. A warning light about the approaching car but didn't know it was going to hit on brakes by itself so forcefully. Car wasn't near the vehicle just in the scenery of the camera.

The panoramic sunroof/front movable glass panel on my Hyundai Sonata N Line appeared to spontaneously shatter while driving on the highway. Weather conditions were clear and normal at the time of the incident. There was no traffic around the vehicle, no bridges or overhead objects nearby, and I did not observe any object strike the roof before the glass failed. The vehicle has approximately 20,000 miles. The glass suddenly developed widespread cracking and a large opening in the panel. The glass also appeared to lift/bulge upward around the damaged area. There was no obvious impact point or bullseye pattern visible that would clearly indicate an object strike. The failed component was the panoramic sunroof/front movable glass panel. The damaged component is still available for inspection. This created a serious safety concern because shattered glass could have entered the vehicle while driving at highway speeds and could have caused distraction, injury, or loss of visibility/control. The vehicle has been inspected by a Hyundai dealership. I was informed the panoramic roof assembly may require replacement. I am filing this complaint because the failure appeared spontaneous and may indicate a defect or structural stress issue with the panoramic roof glass. There were no warning lights, alerts, or prior symptoms before the failure occurred. Photos of the damage are available for inspection.
