Brake, electrical, and steering issues are among the top complaints to the NHTSA from vehicle owners
The all-new 2022 Hyundai IONIQ 5 earned a lot of excitement from the EV community when it was first released. After all, the automaker boasted it was full of “Hyundai quality you can trust.” Yet, there are some less than trustworthy aspects to this model. These include defective service brakes, electrical malfunctions, and steering column issues.

Most Common Problems
A total of 88 complaints were filed with the National Highway Traffic Safety Administration (NHTSA) between April 7 and June 22, 2023. Of these, 5 report that their 2022 Hyundai IONIQ 5 crashed because of various malfunctions.
Over half (56) of the complaints are listed under Electrical System, which is disturbing since this is Hyundai’s first dedicated EV line. These range from problems charging these electric vehicles to faults with safety warning systems and a key fob failing to open car doors to ICCU failure.
There are 12 complaints listed under Service Brakes and another under Parking Brake. Additionally, there are another 2 complaints that mention brake problems. All 3 of the complaints listed under Forward Collision Avoidance involve faulty braking.
The problems run even deeper with a recall signifying trouble with the brakes on all IONIQ 5 models. Without a transmission, the parking brakes are electronic and needed to keep the vehicle from rolling away. When voltage fluctuations occur with the vehicle off and in a parked scenario, the signal can inadvertently disengage the parking brakes momentarily, but it’s enough for the car to roll away. A software update to the Shifter Control Unit (SCU) is required to fix the problem. But the car must be brought to the dealer for repair, which doesn’t make sense since it can get over-the-air updates.
This problem, which potentially affects 10,729 IONIQ 5s, isn’t helping anyone rely on the “Hyundai quality” that is pushed so heavily. Disturbingly, there are already several complaints to the NHTSA reporting that cars crashed because of shifter control unit failures.
Other components and systems mentioned in complaints are the powertrain, structure, and vehicle control. Although there are no NHTSA complaints listed under Airbags. But two of the complaints that involve crashes state that the airbags did not deploy.

Electrical Systems Issues
It’s always disconcerting when the majority of complaints about an electric vehicle are about the electrical system. Even more so when they relate to charging the vehicle.
DC Fast-Charging Problems
There are 2 NHTSA complaints that describe how the deadfront (a plastic cap) on the charging pin becomes dislodged after DC fast-charging at public charging stations.
Both complaints say that the owners now can’t find the cap. This is a major problem because the cap is supposed to cover the conductive part of the pin. With it missing, the person charging the IONIQ 5 may be exposed to potentially harmful electric current, which is highly dangerous.

Safety Warning System Faults
A Hyundai IONIQ 5 owner from Delaware states that after 5 warnings one rainy day, most of the systems involved triggered a fault. The warning lights that came on were: check battery, lane assist warning, the antilock braking system (ABS) warning, parking brake warning, forward collision warning, and blind spot collision avoidance.
What was more disconcerting was that driving to the dealer, “my brakes became steadily lighter and lighter with the manual brake even clicking at times. My braking distance was doubled by the time that I got there. Other owners are seeing the same issue. It sounds quite similar to the Kona Electric recall (20V-748). My car is unsafe to drive.”
A New York owner tells a similar story after the stop vehicle and check brake system and the check engine light warning went on. The Hyundai dealer “fixed” the issue “by removing a component that is unrelated to the braking and security systems and the car became drivable again.” But not for long. About 300 miles later, “the braking system still functioned, but all electronic features were disabled by the car and braking involved a lot of force on the brake pedal to get the car to stop.”
This complaint also mentions that the “Check automatic lane change system” warning sometimes flashes when the car is turned on. “The car is now back with the dealer who ‘fixed’ the issue originally but their EV tech isn’t always there to look at cars, even though the issue is not necessarily EV related as all cars (should) have brakes.”
Problems with the Brakes
Brake problems are a major issue with the Hyundai IONIQ 5. All 5 crashes recorded in complaints to the NHTSA relate to faulty brakes. And, as you can see, the two complaints mentioned above under Safety Warning System Faults both mention brake issues.
One NHTSA complaint says, “The regenerative brakes had an error go off, which caused the brakes to stop working properly. This error went off twice, once in my driveway upon starting my car, then it reset itself. And again while driving, in which I nearly rear ended the car in front of me due to the brakes not working. Hyundai confirmed the error codes but could not reproduce (them). Hyundai eventually replaced components of the brakes, but I do not trust that it won’t happen again. I wanted out of my lease but they refused and made me drive it again, even though I’m terrified of it happening again.”
This IONIQ 5 owner has every reason to be afraid. Here are a couple of complaints that show why. An owner from Arizona was involved in a minor collision. When he rear-ended another car accelerating from a stop light at low speed:
- Forward collision warning did not activate.
- Auto braking did not activate.
- No airbag deployed.
A Florida driver also rear-ended another vehicle, but this time it was because the emergency hand brake didn’t work. It happened while driving at 80 mph. He “was pressing on the brakes while approaching a red light” but “the vehicle would not stop. The complaint goes on to say that “he pulled on the hand emergency brakes to stop the vehicle but the vehicle would not stop.” He rear-ended it, causing the car in front “to lose control and hit another vehicle.” There didn’t appear to be any injuries, but they filed a police report.
Shifter Control Unit Software Error
The first complaint about an SCU error was lodged with the NHTSA in April 2022, before the May 4 recall was announced by Hyundai. The driver, aiming to exit his driveway, tried to put the car in reverse while in park, but the gear shifter didn’t work. As he got out of the car, with the gear shifter in park, the vehicle accelerated into his garage. The garage door and pillar, and the driver-side door, were all damaged. The airbags didn’t deploy on impact, but luckily the car owner wasn’t injured.
His New York dealership inspected the vehicle, which had only 494 miles on the clock. They claimed the failure “was a result of human error.”
Nearly 2 months after the vehicle was repaired, it happened again. Though the gear shifter did eventually move after multiple attempts. By this time the recall was in place and the owner was instructed to take the car to the dealer for the software update.
An owner from California was lucky not to be in the IONIQ 5 when it crashed. The vehicle was parked and unattended at the time. The shifter control unit failed and the vehicle rolled away just as described in the recall notice. The front of the car was damaged in the crash.
Worn Steering Columns
Controlling a vehicle is just as important as being able to keep it parked. Yet, the IONIQ 5 is also suffering from serious steering problems. Even though there are no complaints to the NHTSA about steering (yet), it’s worth mentioning since the problem has been acknowledged by Hyundai in a manufacturer communication.
The notification, a service bulletin, was issued in April 2022. It is only one of two manufacturer communications sent to dealerships about the IONIQ 5 prior to November 2022.
One Edmunds user says, “Purchased the IONIQ 5 Limited last Thursday, 3/24. Over the next couple of days, I noticed that while driving between 60-70 mph that the steering wheel was shaking excessively. I brought it into the dealer on Monday 3/28 and it has been there for 5 days and counting. Now I am stuck paying for a brand new car that I can’t even drive. Was looking so forward to it but am now so disappointed. Please test drive the car multiple times at highway speeds before buying.”
Service Bulletin #22-ST-005H discusses how the vehicle can end up with a bearing noise that’s coming from the Motor Driven Power Steering (MDPS) column worm shaft assembly. When this noise occurs, the worm shaft bearing has to be replaced to fix the issue.
This is one problem that doesn’t only affect the IONIQ 5. It affects 16 models and a total of 51 Hyundai products with model years ranging from 2017-2022. This means that even brand new vehicles may be affected.
