2024 Hyundai Ioniq 5 Brakes Problems

“While stopped at a red light my 2024 Hyundai IONIQ 5, the car moved forward slowly the brake pedal became completely unresponsive and would not slow or stop the vehicle. I had to turn off the engine to bring the car to a stop. This is a complete brake system failure on a vehicle with only approximately 10,000 miles that was purchased new on September 28, 2024. This is a critical safety defect that put myself and others at serious risk.”

On [XXX], I was in New Jersey waiting for my mother to finish shopping. In an effort to preserve battery life, I turned off the engine while waiting. Upon her return, I placed my foot on the brake pedal and started the car. As soon as I shifted the gear into "Drive," the vehicle made an unusual sound and began to roll forward. At no point did I remove my foot from the brake pedal, and I immediately applied more pressure. However, the brakes did not respond. Panicked by the fact that a parked car was directly in front of me, I quickly shifted the gear into "Park" to engage the emergency brake. Fortunately, this action brought the vehicle to a stop, and no damage occurred. I turned the vehicle off and restarted it after which the brakes functioned properly. The experience was extremely alarming. This is not the first time I have experienced this issue. On [XXX], a similar incident occurred while I was stopped at a red light. At that time, I assumed I may not have applied sufficient pressure to the brake pedal. The car rolled forward and made contact with the vehicle in front of me, resulting in a minor accident and a cracked front headlight. Given that this has now happened twice, I am concerned about the possibility of a recurring brake system failure and am worried for my safety and the safety of others. - Brake Failure, it is available for inspection upon request - if I didn’t act quickly and pressed the emergency brake, it would have resulted in an accident. Damage to my car and damage to the car In front of me. And could have resulted in injury to myself. -I have not taken the vehicle to the dealership or service center yet as I have not driven it since the incident. However, I have scheduled an appointment for this upcoming weekend. -there were no warning lamps messages or other symptoms prior to the failure.

My wife was parking the 2024 ioniq and it lurched forward at a high rate of speed and slammed into another car parked in our driveway and drove that vehicle through our home garage door. She feels certain that her foot was on the brake, but even if she accidentally slipped and appleid the brake the forward collision system should have prevented the accident additionally the impact occurred with such force it is unlikely due to human error as it pushed our very heavy 4Runner back 3 feet and thorough a closed garage door.

1. Brake Failure: recently when my brakes stopped responding while driving.The pedal went all the way to the floor, and I barely managed to stop the car. 2. Knocking sound when braking: I started to notice a clunking/knocking sound that would occur when braking and just about coming to a stop.
