Sample complaint excerpts
12V Auxiliary Battery
- [2022] The ICCU has failed for the 2nd time in a year requiring lengthy repairs. The car cannot be driven with a faulty ICCU. The ICCU is responsible for converting AC power to DC for and stepping it up to 800 volts to charge the primary battery. It is also responsible for keeping the secondary 12 volt battery charged.
- [2022] While driving my IONIQ 5 it flashed a power limited warning, went into turtle mode, and then experienced a total loss of power. The 12V battery was dead.
- [2022] Q: What component or system failed or malfunctioned, and is it available for inspection upon request? A: ICCU failed - Not available for inspection (at least at this time, but willing to try and make it work). Q: How was your safety or the safety of others put at risk? A: The ICCU (Integrated Charging Control Unit) is a safety-critical component subject to federal recalls 24V-204 and 24V-868. (
Electric Propulsion
- [2022] ICCU failure occurred while vehicle was operating at 30 MPH, after being charged the night prior and unplugged in the morning at 100% capacity. A sudden pop was heard, and the vehicle indicated that an electrical fault would require the vehicle to be shut down as soon as safely possible. The vehicle went into limp mode and would not exceed 25 MPH.
- [2022] While driving my IONIQ 5 it flashed a power limited warning, went into turtle mode, and then experienced a total loss of power. The 12V battery was dead.
- [2022] ICCU failed at ~27,000 miles. Loud pop came from the under the vehicle. Afterwards, car could only accelerate to 35 mph. Dashboard error message told driver there was an electrical issue and advised us to pull over. Car had to be towed. Currently at the dealer awaiting a replacement. Dealership said it could take "weeks or months" to get a replacement part. Sudden loss of propulsion is a safet
High-Voltage Battery
- [2022] I am filing this complaint regarding Hyundai Motor America's failure to complete a vehicle repair in a timely manner on my 2022 Hyundai Ioniq 5 (VIN: [XXX] ), which has been at Hyundai of Leander, an authorized Hyundai service center in Leander, Texas, since September 2025 — more than six months — awaiting a replacement high-voltage battery. (Case No. XXX) I purchased this vehicle in September 20
- [2022] The Integrated Charging Control Unit (ICCU) has intermittent failures. During the last failure, my wife was on a busy freeway (Interstate 5 near Hwy 120 northbound) in heavy but fast moving traffic. She was driving in the #2 lane (of 4 lanes) when she experienced sudden loss of propulsion. The vehicle slowed to 5 MPH in traffic that was moving 70 to 80 MPH. She had to traverse through the #3 a
- [2022] Car died due to 12v battery failure due to ICCU not working properly in Oct 2023. Did ICCU recall and safety updates with dealer and they installed a new 12v battery. Oct 2025, car dies again due to 12v battery failure to to ICCU. Car has been at dealer for over 2 months waiting for new ICCU part to arrive and be installed. The ICCU system on this vehicle and related vehicles in the Hyundai/Kia li
Charging System
- [2022] For the past few days, our 2022 Hyundai Ioniq 5 (approx. 83,000 miles) has been unable to charge using AC charging (Level 1 or Level 2). The failure is repeatable and consistent across multiple chargers: two separate home Level 2 chargers, the Hyundai-provided Level 1 charger, and a neighbor’s Level 2 charger. In each case, charging either fails to start or stops shortly after initiating. DC fast
- [2022] My 2022 Ioniq5 left me stranded late at night in a freezing rainstorm in March of 2024 when I was 75 miles from home at it failed to charge both D/C fast charging and A/C level 2 charging, despite my trying several different chargers. The car gave me the dreaded "Check E/V System" warning when it failed to charge. It turned out to be the notorious ICCU but also the AC inverter, which had to be r
- [2022] The component that malfunctioned is the Integrated Charge Control Unit (ICCU) and related high-voltage charging system in my 2022 Hyundai Ioniq 5. The ICCU controls AC (Level 2) charging, DC fast charging functions, and power delivery. The ICCU assembly and charging components were serviced and replaced by an authorized Hyundai dealer and are available for inspection through service records. This
Regenerative Braking
- [2022] This is an electric vehicle that features “iPedal” driving, what Hyundai refers to as one-pedal driving. The main safety issue is that when you decelerate using one pedal, which is a fairly aggressive deceleration, the brake lights do not come on unless you lift your foot entirely from the accelerator or apply the brake pedal (which one would rarely do in iPedal mode). Hyundai needs to rethink the
- [2022] The IONIQ 5, like other electric vehicles, uses regenerative breaking. Regenerative breaking can be set at level 1, 2, 3, or i-pedal mode. This determines the strength in which the car will engage regenerative breaking automatically when the position of the accelerator petal is raised above the current speed. i-pedal mode is full one-pedal driving, allowing the driver to slow to a stop without use
- [2022] When using the car in "i-Pedal" (one-pedal driving) mode — the highest brake regen setting — the car can come to a complete stop whenever I lift my foot off the accelerator pedal, without touching the brake. While in this mode, when I fully lift my foot off the accelerator, the rear brake lights illuminate as expected, however, I often slowly reduce pressure on the accelerator pedal to come gent
Hybrid Drivetrain
- [2023] The contact owns a 2023 Hyundai Ioniq 5. The contact stated that the recall repairs for NHTSA Campaign Number: 24V868000 (Electrical System) and 24V204000 (Electrical System) were completed; however, the repairs failed to prevent a failure from occurring shortly afterwards. The contact stated that while attempting the charge the hybrid battery, the vehicle failed to charge to full capacity as inte
- [2025] For the HYUNDAI Ioniq 5 XRT, the ICCU, fuse and perhaps hybrid battery malfunctioned. We were in a disabled car on a 4 lane highway with traffic: On February 10, 2026, as we drove out of our home we heard a loud pop. As we got out onto a large 4 lane road near our house, the notice “Check Electrical System” came on and the car’s power was drastically reduced. We made a U turn and drove (20 mph) b
- [2025] I leased a 2025 Hyundai Ioniq 5 (VIN: [XXX] ) on September 16, 2025 from Route 1 Hyundai in Monmouth Junction, New Jersey. Since I bought the vehicle, I have had to return it to the dealership a total of one time. My vehicle has been out of service for repairs since November 19, 2025 for a total of 35 calendar days. The current mileage on my vehicle is 3,026 miles. My vehicle has been in service a
Source: classified from NHTSA complaint and recall data. "Battery-related" includes high-voltage propulsion battery, charging system, hybrid drivetrain, electric propulsion, regenerative braking, 12V auxiliary battery, and thermal-event complaints. Other complaints (suspension, steering, brakes, infotainment) appear in the engine and vehicle-level sections. Rates are absolute counts, not normalized per-VIN — high-volume models naturally produce more raw complaints than low-volume ones. Self-reported death and injury counts are capped per complaint to limit form abuse.
