NHTSA Complaint #11673537 — 2022 HYUNDAI TUCSON

The vehicle's brake system intermittently fails after driving over bumps or uneven roads. The brake pedal becomes soft and unresponsive, and the vehicle continues rolling forward for several seconds before the brakes finally engage. This has happened repeatedly while driving home from work. On one occasion, the vehicle rolled through a red light and I had to swerve into oncoming traffic to avoid a collision. This issue first became noticeable in 2022 and has worsened over time. It puts both my safety and the safety of others at serious risk. There are no warning lights or error messages before or during the failure. The vehicle is available for inspection upon request. Independent mechanics have confirmed that brake pads, rotors, and fluid levels are in good condition. They suggested the cause could be air in the brake lines, a malfunctioning ABS system, or a faulty master cylinder—all potentially covered by the manufacturer’s warranty. The manufacturer’s service center initially refused to inspect the vehicle without an upfront diagnostic fee and only offered assistance after I escalated the matter through repeated complaints. The service director later described the issue as “unsettling but normal,” which is not accurate according to independent professionals. The problem has not been resolved and continues to occur regularly. I am requesting that this be formally investigated as a potential safety defect.
