2022 Hyundai Ioniq 5 brakes problems

Filed Sep 5, 2026 · Acceleration, Brakes · WA

This report is an addendum to report 11762283 that was made yesterday. The vehicle allows driving with the rear liftgate ajar, however under some circumstances it engages the EPB when the vehicle comes to a stop while the gear state is still Drive. The gear state of the car remains in Drive when the EPB engages. This presents the driver with the choice, in the middle of the road and possibly in the middle of an intersection, of either exiting the vehicle and rearranging contents of the vehicle to allow the rear liftgate to close, or activating the accelerator to continue driving with the traction motor overpowering clamped EPB. Neither option is safe. I have attempted to reproduce this unsafe state of the vehicle and was successful in one case and unsuccessful in another. My hypothesis for the differentiating factor is the top speed reached prior to decelerating to a stop: in the first case, 13mph, and in the second, 15mph. I have attached a single frame from one of two videos, of the successful case. The instrument display shows gear state is Drive, the car is moving, high torque is being applied by the traction motors (but typically the screen center shows ADAS state, and there is no indication of instantaneous traction torque), and the EPB is engaged. The car is in the middle of an intersection at the time.

After coming to a stop at a stop sign, and while the gear state was in Drive, the vehicle auto-applied the electronic parking brake because the tailgate was ajar. Gear state remained in Drive. Upon accelerator input, the parking brake did not release, and the vehicle delivered propulsion torque overcoming the parking brake. As a result, the vehicle accelerated and drove several blocks with the rear brakes fully clamped, which was only effectively indicated by a smell and smoke emitted from the rear wheel wells. An irritating repetitive audio and large flashing visual alert in the display cluster indicating the tailgate state distracted from any additional indications that may have been displayed. That distracting indication was continuously active from when gear state was first switched to Drive and did not correlate with EPB engagement.

Unknown. It just happened in November and i called Hyundai but they didn't want to fix it. I haven't been able to use my car properly since then.

I am writing to report a serious safety incident involving my 2022 Hyundai Ioniq 5 and to request a thorough investigation and guidance on next steps. On Jan. 3, 2026, at approximately 6:15 p.m. on a snowy day, we parked our car in the driveway of a weekend rental home near Lake Tahoe, CA. The driveway had a slight slope toward the house, and we backed the car down the driveway with the rear of the car facing the house. My husband turned off the car, then all five occupants exited the vehicle, closed the doors, and began unloading items from the trunk. The car began rolling backwards toward us and the house. It only stopped after pinning my husband into a snowbank created by a snowplow. The other three adults and our [XXX] niece narrowly avoided being struck. While pinned behind the vehicle, my husband had to dig out some snow to reach into his pants pocket and retrieve the key fob. I then moved the car forward a few feet to free him. Although he was pinned in the snow, my husband was (thankfully) not seriously injured. After freeing my husband, I put the car in Park and turned it off. In this model, the parking brake engages automatically; there is no separate parking brake button or lever. A few minutes later, without anyone in or near the vehicle, the car again rolled backwards down the driveway into the same snowbank. Tracks in the snow clearly indicate that the wheels rotated and the car rolled; it was not sliding on ice with the brakes applied. In other words, the parking brake and/or Park mechanism failed to hold the vehicle in place in sub freezing, snowy conditions. The temperature at this location and time was in the mid 20s °F. After returning home from our trip, we took the car to our Hyundai service center, which has performed all maintenance since we purchased it in 2022. The service center performed all standard diagnostics but was unable to replicate the failure conditions. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When coming to a stop on a slight incline, the vehicle will come to a full and complete stop and occasionally begin to roll backwards after half a 2nd without changing brake pedal position. If the brake pedal is not push further down, the vehicle will continue to roll backwards. I have tested this on multiple IONIQ 5 models with the same result (2022 and 2023). This could cause a collision if there is another car behind the problem vehicle. No warning lamps. Both vehicles have done this since new. Nothing is wrong with either of the vehicles according to multiple dealers.

The contact owns a 2022 Hyundai Ioniq 5. The contact stated that after the vehicle was parked on a slight incline on the road, the gear shifter was shifted to park(P), and the vehicle was turned off. The contact stated that while exiting the vehicle, the vehicle started to roll backward. The contact was able to jump back into the vehicle and depress the brake pedal to stop the vehicle. The contact stated that the vehicle was still in park(P); however, when the brake pedal was released, the vehicle started rolling away again. The contact had not engaged the parking brake. The contact stated that the vehicle was turned off and restarted and was able to shift into park(P) and the vehicle remained stationary. The contact stated no warning light was illuminated.

When you place the car in park a recall was done so that the emergency parking brake automatically engages. Well between 30 seconds to a minute after the car is in park, the brake disengage. When you go to set it manually after it disengage, it will still disengage.

Driving down I95 at 75mph. Heard loud "thunk" and car lost both power and brakes. Warning lights on the dashboard said to check brake system. I was unable to pull onto the shoulder due to construction barricades in place. The car slowed to 10mph and continued until I was able to pull over onto the shoulder. This was very dangerous given the highway traffic speeds, construction zone with limited emergency pull over space, and due to it being night time. Turning it off and on again restored power but it happened 4 more times before I was able to make it to an exit. This seems to be a common issue with this model. I have already performed the ICCU recall that was supposed to address this

The car gave an warnings of “Check Electric Vehicle System@ and started slowing down in the middleman of the road. I could have been easily rear ended or got into a serious injury. After googling, it seems almost all if not most of ioniq 5 are having this issue after certain mileage

In stop and go traffic on freeway, car was moving at about 5 miles an hour but car kept moving, collision warning and automatic braking did not activate. Had to turn off car and coast to a stop. Nearly collided with vehicle in front
