2024 Hyundai Palisade brake problems

Two times my car has lost its ability to break, and when I try to break it feels like the break pedal was very hard to push down. The car was very lurchy but finally came to a stop when the breaks finally engaged. The feeling is like when you press on the breaks when you are sliding on ice.

At slower speeds, while braking or coming to a stop, if a bump or uneven surface in the road is encountered the car will violently shake. The steering wheel will shake left and right and braking action is lost.

Car begins to shake if brake is applied when diving over uneven terrain. Acts like ABS is applied but car does not slow as it should. No lights or indicators flash when this occurs. Fortunately was able to stop before rolling into intersection as I was already traveling at slow speed.

Traveling in a slow lane of traffic. Brakes malfunctioned when I began to brake over broken/ not smooth road. Car began to shake hard and loud. Brakes locked but car was still rolling. I was unable to control the vehicle almost rear ending the car in front of us. I didn’t know what to do or how to stop us before we crashed.

When driving at a slow speed on dry uneven pavement, such as repaired asphalt around potholes, and the breaks are applied, the abs system kicks on and launches the car forward, sometimes in a series of occurances, before the car will stop. We brought the car to the dealership service department.
