Hyundai EV battery fires, lost power and rollaway recalls explained
⚠ 4 carry a park-outside (fire risk) advisory.
Fire risk around high-voltage batteries is the thread running through Hyundai's electrical recalls. Kona Electric (2019-2020) and 2020 Ioniq Electric were recalled twice for lithium-ion cells that can short-circuit; 2025-2026 IONIQ 5 and 2026 IONIQ 9 for improperly tightened high-voltage bus bars; and 2023-2024 Ioniq 5 for misaligned battery electrodes that can ignite while parked or driving. A second pattern is lost drive power: the Integrated Charging Control Unit on 2022-2025 IONIQ 5 and 6 and Electrified Genesis models stops charging the 12-volt battery, and that recall was reissued as 24V-868. A third is unintended acceleration on 2017-2019 Ioniq Electric and 2021-2023 Elantra Hybrid. Smaller ones cover 12-volt cable chafing on 2024 Kona and Park-shift rollaway on 2025 Tucson and Santa Cruz.
Warning signs to watch for
- Reduced acceleration and power, or the car dropping into fail-safe mode (Ioniq Electric)
- The vehicle accelerating after you release a pedal (Ioniq Electric, Elantra Hybrid)
- Loss of drive power while moving, or signs the 12-volt battery is not charging (ICCU recalls)
- Being able to shift out of Park without pressing the brake pedal (2025 Tucson, Santa Cruz)
- Several battery recalls give no warning at all — a short or misaligned cell can start a fire while the car sits parked
Is it safe to keep driving?
No recall here tells owners to stop driving. Four come with parking instructions. Hyundai asks owners of 2019-2020 Kona Electric and 2020 Ioniq Electric, 2025 IONIQ 5 with the loose bus bar, and 2023-2024 Ioniq 5 with misaligned electrodes to park outside and away from buildings until the repair is complete; the 2023-2024 notice also limits charging to 80 percent. For 2025 Tucson and Santa Cruz, use the parking brake every time you park. The rest can be driven until the repair, but the fire and power-loss recalls deserve the earliest appointment you can get.
What the free repair involves
Repairs split by cause. For the battery recalls, dealers update Battery Management System software, inspect the lithium-ion battery, tighten or replace bus bars, or replace the entire high-voltage battery assembly. For the ICCU recalls, they inspect and replace the ICCU and its fuse and update its software. Elsewhere it is software (EPCU, motor control, HPCU), wiring sheathing, rerouted console wiring, or a reinstalled starter terminal cover — always free.

Common questions
I already had the ICCU recall done — do I need to go back?
Yes if your repair was done under the earlier March 2024 recall. Hyundai replaced that recall with NHTSA number 24V-868, and the notice says vehicles already repaired under it must still have the new remedy completed.
Why does Hyundai want my Ioniq 5 charged to only 80 percent?
That instruction comes with the 2023-2024 Ioniq 5 recall for misaligned battery electrodes, which can lead to a fire while parked or driving. Until the high-voltage battery assembly is replaced, Hyundai asks owners to cap charging at 80 percent and park outside.
Can these problems hit while I am driving, not just parked?
Yes. The ICCU recalls describe a loss of drive power while the vehicle is moving, and the Ioniq Electric and Elantra Hybrid recalls describe unexpected acceleration after a pedal is released. The 2023-2024 Ioniq 5 battery fire can begin parked or driving.
