This page covers 11 recalls, 247 owner complaints and EPA fuel economy for the 2025 Hyundai Ioniq 5.
114 MPGe combined
Small Sport Utility Vehicle 2WD
Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted.
The 2025 Ioniq 5 draws a notably concentrated complaint picture, with electrical system issues dominating owner reports by a wide margin. The most frequently described problem involves the integrated charging control unit (ICCU) failing, owners report hearing an audible pop followed by a "Check Vehicle Electrical System" warning, after which the vehicle loses the ability to charge at home, shuts down entirely, or becomes undriveable. Some owners describe the failure happening with no prior warning at relatively low mileage. The propulsion system is the next most-reported area, with owners describing sudden loss of power, speed limiting to well below posted limits, and complete vehicle shutdowns requiring a tow. A smaller but recurring pattern involves the steering system behaving unexpectedly, owners describe the car making sudden lateral corrections or pulling toward another lane, with an accompanying warning light and noise.

By System
The 2025 Hyundai IONIQ 5 has 11 recalls, the most serious being a high-voltage battery connection that can short-circuit and cause a fire, along with a braking software defect on IONIQ 5 N models where activating the left-foot braking feature can reduce stopping power and allow the vehicle to continue accelerating.
The braking issue on N models has been the subject of multiple repair attempts, and an earlier software fix did not fully resolve the problem, requiring a second repair. On the chassis side, rear suspension fasteners can loosen and detach, causing loss of vehicle control, and separately, rear suspension alignment bolts on certain vehicles may not hold proper tension, reducing stability control. Both issues raise the risk of a crash. There are also occupant safety concerns: front seatbelt retractors may not be securely mounted and could fail to restrain occupants in a crash, and a wiring fault in the rear floor can prevent the rear side airbags from deploying. Rounding out the list, the right-side headlight on some vehicles carries an incorrect aim label, which can result in poorly aimed beams that reduce road visibility at night.
