2022 Hyundai Ioniq Hybrid brakes problems

Filed Sep 1, 2026 · Brakes · NC

The Auto Hold and EPB orange warning lights emerged while commuting to work, which are associated with the brakes. The problem was diagnosed by the dealer because the other car we own is also an Ioniq and we have had two different Auto Hold problems noted with that automobile (the federal safety agency tracking numbers 11761449 and 11761458), therefore we sadly have experience detailing this defect. There were no issues with the car prior to the Auto Hold/EPB warning lights appearing. The vehicle has been inspected by the dealership and the part has been replaced.

The Auto Hold and EPB orange warning lights have emerged for the second time on this vehicle after fixing an initial Auto Hold/EPB problem at mileage ~88-89K (tracking number assigned by the federal safety agency for this issue was 11761449). The mechanic stated this feature can malfunction in the error mode leading to unprompted braking in a previous conversation. After taking it into the dealership for review, it was revealed that a different wheel's braking machinery was compromised and needed to now be replaced making it the second repair of the same part on first the left rear now the right rear wheels. The first occurrence of the second warning light emerged ~94K. Of note, we purchased another Ioniq and have just experienced the same issue for the second times in that vehicle at mileage ~31K and ~34K, so it appears to be a common defect in this automobile.

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.

The Electronic Parking Brake (EPB) on my 2022 Hyundai Ioniq Hybrid has a recurring safety defect. The EPB warning light continues to come on and off intermittently even after EPB components were replaced. Diagnostic Trouble Codes C2416 and C2417 have been detected multiple times. This issue first occurred at around 10,000 miles, while the vehicle was still under factory warranty. At that time, the dealer only performed a cleaning procedure, which did not resolve the problem. Over the years, I returned to the dealer multiple times, but they refused to perform repairs unless the warning light was present during diagnosis. Frequently, the light turned off before inspection, leaving the defect unresolved. At approximately 87,000 miles, the dealer finally replaced EPB components at my expense (out-of-warranty repair). However, even after this replacement, the EPB warning light has continued to reappear, proving that the underlying safety defect was never fixed. This is a serious and ongoing safety concern. The EPB is a critical braking system component, and its failure could prevent the vehicle from safely parking or holding on a slope. Because this problem began during the warranty period, was never properly resolved, and persists even after paid repair and part replacement, I believe this represents a manufacturing defect that requires investigation and potential recall.

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.

The "Auto Hold and EPB" yellow indicator light constantly turns on, which, according to the owner's manual, suggests a sensor issue. When I press Auto Hold after starting the car, the light comes on immediately. Even if I don’t press the Auto Hold button, the light still turns on. Yesterday, after driving approximately 9 miles, the light came on again and began beeping every 7 to 8 minutes while driving.
