Service brakes
15 reports
“The Auto Hold and EPB orange warning lights have been a recurring problem with our 2022 Hyundai Ioniq. We first noticed the car exhibit a jerky/jolting hesitation after accelerating from a complete stop which was reported to the dealership with confirmed paperwork at ~52K miles. The Auto Hold and EPB orange warning lights have been documented via photographs and video on been active at mileage ~58K and 72K, but the dealership could not reproduce (or scan the codes?) the warning light signature or jerking motion. Additionally, the car indicated that is was trying to either activate or deactivate the Auto Hold function even when the car was in motion and is never turned utilized by any driver of the vehicle. Even though this problem was described as hazardous and may cause the brakes to lock leading to an accident. Finally at ~88K miles the dealership was capable of properly diagnosing the problem and replaced the left rear caliper with CPB motor.”

7 reports2 crashes
“Forward collision warning light appears on, when there is no noticeable event immediately. "Glitch-like" flash across the dashboard appears. Vehicle continues to display wheel misalignment after two alignment procedures, values indicate possible safety concern.”
Lane departure
2 reports1 crash
“I was in an accident on October 7, 2022. There was almost $5,000 in damage. Repairs were made, but several repairs were left unattended and I am put at risk of safety. The Seat Tracking was out of alignment and could not be verified by mechanic, although it was verified by the body shop. The Forward Collison Warning light comes on intermittently, as do other gauge lights, after the accident.”

No warning lights illuminated. The vehicle was taken to a local dealer, where it was diagnosed; however, the failure was not identified. The manufacturer was made aware of the failure. The failure mileage was approximately 300.”
Power train
1 report
“The contact owns a 2022 Hyundai Ioniq Hybrid. The contact stated that while operating the vehicle with the Smart Cruise Control activated, the EPB (Electronic Parking Brake) warning light activated. Additionally, while stopped, the EPB erroneously deactivated, causing the vehicle to drive forward, and the driver had to manually depress the brake pedal to stop the vehicle. The contact stated that the vehicle almost struck a pedestrian during the failure. The vehicle was taken back to the dealer who was unable to determine the cause of the failure. The contact stated that on another occasion, while driving at an undisclosed speed, the vehicle suddenly lost automotive power and was towed to the local dealer who diagnosed that the transmission was faulty and needed to be replaced. The vehicle was not yet repaired. The failure mileage was 40,000.”
