2022 Hyundai Ioniq 5 Reliability Score & Common Problems

Owners of the 2022 Hyundai Ioniq-5 frequently report issues related to the Integrated Charging Control Unit (ICCU), which can fail unexpectedly, leading to the vehicle becoming inoperable or entering a "limp mode" with limited driving capability. Symptoms often include warning messages such as "Check vehicle electrical system" and a noticeable drop in speed, sometimes resulting in the vehicle stopping completely. Some complaints also mention charging problems, where the vehicle's charging process stops prematurely, and issues with the brake lights not activating during deceleration in "i-pedal" mode. Safety implications include potential risks of being rear-ended due to sudden power loss or lack of brake light warnings. These issues appear to occur at various mileage ranges, with some vehicles experiencing problems shortly after purchase.

Owners report frequent issues with the Integrated Charging Control Unit (ICCU) in the 2022 Hyundai Ioniq 5, often leading to sudden power loss and vehicle shutdowns while in motion. Symptoms typically include warning messages such as "Check EV Connection" or "12v Battery Critical," followed by a complete loss of vehicle power and inability to operate hazard lights or steering. These failures occur without prior warning and have been noted in vehicles both on highways and local roads, posing significant safety risks, particularly if occurring at high speeds or in traffic. Complaints also mention that the ICCU failure is often accompanied by a blown fuse, and repairs are delayed due to parts being backordered. Prospective buyers should be aware of these issues, as multiple complaints highlight the potential for dangerous driving situations and extended vehicle downtime.

Owners of the 2022 Hyundai Ioniq-5 frequently report issues with the vehicle speed control systems, particularly involving the smart cruise control and accelerator functions. Common symptoms include sudden deceleration on highways and the car becoming unresponsive, necessitating a restart to resume normal operation. These issues often occur without warning, and one report involves a crash due to a shifter control unit failure, resulting in the vehicle rolling away while parked. Several complaints also highlight problems following a recall repair, with decreased acceleration in certain drive modes. These problems are reported at various mileages and can pose significant safety risks, especially in high-speed or busy traffic situations.

Owners report several issues with the forward collision avoidance system in the 2022 Hyundai Ioniq-5. Commonly, the system either fails to activate during potential collisions or triggers false alarms, leading to unexpected deceleration. Two incidents involved crashes, one where the system did not engage and another where the vehicle spun out of control, possibly due to a lack of ABS activation. Complaints frequently mention error messages related to radar alignment and blocked radar sensors, with some owners noting these issues can occur at various mileages. These problems can pose safety risks, including sudden deceleration in traffic and failure to prevent collisions.

Owners of the 2022 Hyundai Ioniq 5 report issues related to the service brakes, with several complaints highlighting problems with the vehicle rolling backwards when parked on inclines, suggesting potential failures in the parking brake system. Additionally, some owners describe the vehicle rolling backwards after coming to a stop on a slight incline unless additional brake pressure is applied. Another common issue involves the regenerative braking system, where brake lights do not activate during significant deceleration in i-pedal mode, potentially increasing the risk of rear-end collisions. Complaints also mention electronic system errors resulting in limp mode activation, requiring increased pedal force for braking. These issues occur at various mileages, with some problems appearing soon after purchase, and they present safety implications such as near collisions and potential loss of control.

Owners of the 2022 Hyundai Ioniq 5 report issues with the vehicle rolling away when parked, even when the gear shifter is in the park position. Complaints frequently mention that the vehicle, after being parked and turned off, begins to roll, particularly on inclines, and in one instance, resulted in a crash into a wall. The reported incidents occur at mileages of approximately 700 and 25,000. These issues can pose significant safety risks, as evidenced by the crash incident, and may be related to a known recall, although not all vehicles appear to be covered. Buyers should be aware of these potential parking brake malfunctions when considering this vehicle.

Owners of the 2022 Hyundai Ioniq 5 report issues related to unexpected power loss while driving. One complaint describes the vehicle losing power when the "EV Start Stop" button is accidentally pressed, resulting in a sudden inability to accelerate, particularly noted at speeds of 15-20 mph. Another owner details a rapid decrease in speed from 55 mph to 22 mph, accompanied by dashboard warnings such as "check vehicle system" and an orange battery icon, with the vehicle ultimately stopping completely. These incidents, which occur without warning, highlight potential safety implications due to the abrupt loss of vehicle control. No mileage patterns are specified in the complaints, but the safety impact of these issues, particularly at highway speeds, is a concern for potential buyers.
