Two ICCU recalls, five open safety recalls total. Ioniq 6 power loss or MOSFET failure may qualify for a California buyback. Free case review.
The Hyundai Ioniq 6 arrived as the aerodynamic sibling to the Ioniq 5 — a sleek electric sedan designed to stand apart in a crowded EV market. What it shares with the Ioniq 5 is something no owner signed up for: a defective Integrated Charging Control Unit (ICCU). Every 2023, 2024, and 2025 Ioniq 6 uses the same E-GMP platform as the Ioniq 5, and every one of them carries the same ICCU MOSFET defect that has now triggered two federal safety recalls. The failure mode is alarming. The ICCU's internal metal-oxide semiconductor field-effect transistor — the MOSFET — can fail under electrical overvoltage events that occur at the start or end of the 12V battery charging cycle, or under thermal stress during normal driving. When it fails, the high-voltage ICCU fuse opens. The 12V auxiliary battery stops receiving charge. The vehicle detects the fault and enters a design-intended fail-safe mode: it warns you with escalating dashboard messages — 'Check Power Supply,' 'Power Limited' — and then progressively reduces drive power until the car is completely inoperable. Steering, brakes, and airbags remain functional during this window, but owners report having as little as 22 to 45 minutes from the first warning to total loss of propulsion. Hyundai's first ICCU recall (24V-204, March 2024) covered 18,017 Ioniq 6 vehicles and offered a software-only remedy. That fix was proven insufficient. In November 2024, Hyundai filed a second, expanded recall (24V-868) covering 28,932 Ioniq 6 units — including vehicles already repaired under the first recall. A class-action lawsuit filed in 2026 alleges that even replacement ICCU units carry the same defect and are failing again. On top of the ICCU issue, 2023-2025 Ioniq 6 owners face a range of additional safety recalls: a charging port door that can fly off at highway speeds, front seat belt anchors that can detach after routine service, and a rear driveshaft fracture issue on certain early-production AWD models. California's Song-Beverly Consumer Warranty Act gives you the right to a repurchase or replacement when a manufacturer cannot fix a safety defect after a reasonable number of attempts. If your Ioniq 6 has been back to the dealer for ICCU events, power-loss warnings, or other recall repairs, your service record may already tell the story.
The issues owners report most, ranked by severity — each one verified against a cited NHTSA source.
Dashboard warning lights ('Check Power Supply,' 'Power Limited'); car enters limp mode with progressively fading power; vehicle eventually unable to drive; 12V battery dead after ICCU fuse opens.
Sudden loss of motive power while driving with no warning; vehicle may stop accelerating unexpectedly.
Charging session stops unexpectedly or charges at much lower speed than expected when plugged into a 240V Level 2 charger; charging restarts on its own or requires unplugging and replugging.
Charging port door flies off or detaches while driving at highway speeds; door panel missing after driving.
Seat belt anchor visibly loose or detached from seat frame after vehicle serviced; seat belt does not remain properly attached; belt may pull free from anchor point.
Loss of drive power while driving; differential locks up; vehicle may stop moving or handle erratically.

Dashboard warning lights ('Check Power Supply,' 'Power Limited'); car enters limp mode with progressively fading power; vehicle eventually unable to drive; 12V battery dead after ICCU fuse opens.
Loss of motive power is a substantial impairment of use and safety. Recall 272 superseded Recall 257; some vehicles required repeat service — multiple repair attempts support a lemon-law claim. Post-recall ICCU re-failure documented in class-action filings.
ICCU software update; ICCU fuse inspection and replacement; ICCU unit replacement if DTC P1A9096 detected.
Sudden loss of motive power while driving with no warning; vehicle may stop accelerating unexpectedly.
Sudden loss of drive power is a safety defect affecting drivability. Small population (913 units) but defect is manufacturing-origin and confirmed by NHTSA.
Dealer replacement of both rear inner driveshafts at no charge.
Charging session stops unexpectedly or charges at much lower speed than expected when plugged into a 240V Level 2 charger; charging restarts on its own or requires unplugging and replugging.
A BEV that cannot reliably complete a home charging session is substantially impaired in its primary use. Multiple failed charging events before the TSB fix, or continued failures after, strengthen a lemon claim.
VCMS software update (Service Campaign 9B5 / TSB 24-01-051H) enabling self-restart so charging resumes at full speed once connection stabilizes.
Charging port door flies off or detaches while driving at highway speeds; door panel missing after driving.
Detached body panels at highway speed create road hazard for other drivers. Secondary lemon-law issue; most relevant when combined with other defects.
Dealer applies adhesive to charging port door assembly at no charge.
Seat belt anchor visibly loose or detached from seat frame after vehicle serviced; seat belt does not remain properly attached; belt may pull free from anchor point.
Unrestrained occupant in crash is a severe safety defect. Particularly compelling where vehicle has had multiple service visits; anchor damage occurs at dealership — Hyundai-caused defect.
Dealer inspects anchors and installs reinforcement insert in retainer clip or replaces anchor assembly. Redesigned production anchor implemented by March 2026.
Loss of drive power while driving; differential locks up; vehicle may stop moving or handle erratically.
Sudden drive-power loss or drivetrain lockup is a serious safety defect. Very small population (2 US units) but confirms manufacturing quality-control failures on E-GMP drivetrain.
Dealer replaces complete gear drive unit assembly (part 44000-18NB0) at no charge.
open
Snap-on seat belt anchor retainer clip can be damaged during routine maintenance, allowing the seat belt anchor to detach from the seat frame.
open
Charging port door and outer panel retaining hooks may not be sufficiently engaged during assembly; inadequate adhesion can cause panel to separate from vehicle when exposed to highway-speed air pressure.
open
ICCU MOSFET may fail under overvoltage or thermal stress, opening ICCU fuse and disabling 12V battery charging; vehicle enters fail-safe mode with progressive power reduction until total loss of drive power.
open
Differential gear bolts in the rear gear drive unit may not be properly torqued during manufacturing by supplier Hyundai Transys, risking bolt loosening under load.
superseded
ICCU may be damaged by electrical load conditions, stopping 12V battery charging and resulting in loss of drive power.
open
Rear inner driveshafts improperly heat-treated due to manufacturing defect at Hyundai WIA supplier (quenching oil contamination on induction coil), leaving shafts susceptible to fracture.
Every item below comes from this vehicle's documented defects. The more you recognize, the more a free case review is worth your time.
California's Song-Beverly Consumer Warranty Act — commonly called the lemon law — entitles you to a repurchase or replacement vehicle when a manufacturer cannot fix a defect after a reasonable number of attempts. For safety defects like sudden loss of drive power, California presumes that two repair attempts may be sufficient to trigger your rights. For non-safety defects, four attempts or 30 or more cumulative days out of service during the warranty period can trigger the same presumption. If your Ioniq 6 qualifies, you may be entitled to a full vehicle repurchase (your purchase price including taxes, registration, and finance charges, minus a mileage offset), a replacement vehicle of comparable value, or a negotiated cash settlement. Under Song-Beverly, Hyundai pays your attorney fees if you prevail — meaning most California lemon law cases cost the owner nothing out of pocket. The Ioniq 6's ICCU defect history is particularly relevant: two successive recalls for the same safety-critical component, the first fix proven insufficient by NHTSA's own findings, and a 2026 class-action alleging replacement parts carry the same flaw. Owners who were repaired under Recall 24V-204 and then experienced another ICCU failure have documented evidence of multiple repair attempts on the same safety system. The above is general information only and is not legal advice; every case turns on its specific facts, dates, and warranty coverage.
“Could not duplicate” doesn't mean the defect isn't real. Here's exactly what to do to protect a potential California lemon-law claim.
Document the moment it happens. Photos, video, and screenshots of any warning lights — with the date and the mileage.
Get a repair order every visit — even “found nothing.” That paperwork is the foundation of a claim.
Check your VIN at nhtsa.gov/recalls. Note any recall that has no available remedy yet.
Track your out-of-service days. California law counts the cumulative days your vehicle spends in the shop.
Keep loaner & rental records. Alternate-transport paperwork during long repairs matters.
Save everything in one place. Symptoms, dates, repair orders, and every repeat visit — the intermittent ones especially.
Dealers sometimes close Ioniq 6 repair orders as 'unable to duplicate' — particularly for ICCU-related power-loss symptoms that clear temporarily when the 12V battery is recharged or when the car sits off overnight. Here is what to do if that happens: 1. Before the dealer visit, document everything. Note the exact dashboard messages displayed, the date, time, outside temperature, how long you had been driving, and whether the car had recently finished a charging session. Photograph any warning lights. Write down how many times you have seen the same warning. 2. Request a printed DTC report that includes stored and historical codes, not just active codes. The critical diagnostic code for ICCU MOSFET failure is P1A9096. Under Recall 24V-868, if P1A9096 appears in stored or historical data, the ICCU unit must be physically replaced — not merely software-updated. A dealer who clears codes without checking history may miss the required hardware replacement. 3. Ask specifically whether the full Recall 272 (24V-868) procedure has been completed: GDS scan for P1A9096, ICCU replacement (if DTC confirmed), fuse replacement in the correct order, and ICCU software update per TSB 24-01-086H. Also ask whether the companion VCU update (TSB 24-01-088H) was performed at the same visit. 4. If your vehicle was previously serviced under Recall 257 (24V-204), which covered 18,017 Ioniq 6 units in March 2024, confirm whether the current Recall 272 work has also been completed. Vehicles remedied under the first recall still require the second recall's hardware procedure. 5. Keep every repair order, including UTD visits. Under California lemon law, a UTD visit still counts as a documented repair attempt. The accumulation of visits for the same symptom is precisely the evidence a lemon law claim is built on.
The Ioniq 6's ICCU problem is the same defect as the Ioniq 5 — same platform, same part, same failure mode. Hyundai issued a first recall in March 2024, confirmed the fix was insufficient by November 2024, and issued a second recall. As of 2026, a class-action is proceeding with allegations that replacement ICCU units are failing again. If you own a 2023, 2024, or 2025 Ioniq 6 that has been serviced for power warnings or loss of drive power — or if you have been to the dealer for any of this vehicle's five active recall campaigns — pull your repair orders and have a California lemon law attorney review your situation. The consultation costs you nothing.
— The Margarian Law team
Have you taken your Ioniq 6 in for a 'Check Power Supply' or 'Power Limited' warning, a loss of drive power, or any of the vehicle's five open recall campaigns? If your 2023, 2024, or 2025 Ioniq 6 was serviced under either the 2024 ICCU recalls — or if it failed again after being repaired — your service history may already qualify for a California lemon law buyback. The consultation is free. Find out where you stand.
The ICCU recall addresses a defect in the Integrated Charging Control Unit that can cause the internal MOSFET to fail, open the high-voltage ICCU fuse, and cut off charging to the 12-volt auxiliary battery. Without 12V charging, the vehicle enters a fail-safe mode that progressively reduces drive power until all propulsion is lost — a safety risk if it occurs at speed. If you own a 2023, 2024, or 2025 Hyundai Ioniq 6, your vehicle is included. Recall 24V-868 (Hyundai internal Recall 272, filed November 2024) covers 28,932 Ioniq 6 units produced between December 14, 2022 and the recall filing date. It supersedes an earlier recall, 24V-204 (Hyundai Recall 257, March 2024), which covered 18,017 Ioniq 6 units with a software-only fix that proved insufficient. Vehicles repaired under the first recall also require the full hardware procedure under the second. Check your VIN at nhtsa.gov for current open recall status.
These are the ICCU fail-safe warnings — the vehicle is telling you its 12V auxiliary battery is losing its charging source because the ICCU's internal MOSFET has likely failed. The car will progressively slow and can lose all drive power within approximately 22 to 45 minutes of the first warning. Steering, brakes, and airbags remain operational during this window, but you should not continue driving to a destination. Signal and move to the shoulder or a safe stop as soon as possible. Do not attempt to drive to the dealership. Call for roadside assistance. Note the exact warning messages, the time, mileage, outside temperature, and whether you had recently completed a charging session. Photograph the instrument cluster. When the vehicle reaches the dealer, ask them to check for Diagnostic Trouble Code P1A9096 in stored and historical codes — not just active codes. If P1A9096 is present in any form, the full ICCU unit must be replaced under Recall 272 (24V-868), not merely software-updated. Keep a copy of the repair order.
Yes. This is an active and documented concern. The first ICCU recall (24V-204, March 2024) used a software-only remedy — a soft-start logic change intended to reduce the overvoltage spikes that trigger MOSFET failure. NHTSA confirmed this fix was insufficient when new ICCU failures continued to occur in vehicles already remedied under 24V-204. That finding prompted Hyundai to issue Recall 24V-868 in November 2024, requiring physical ICCU and fuse replacement for affected vehicles. As of 2026, a class-action lawsuit alleges that even the replacement ICCU units supplied for Recall 24V-868 carry the same underlying design defect and are failing again in service. If your vehicle failed again after an ICCU recall repair, you have documented evidence of multiple repair attempts on the same safety system — exactly the repair history that supports a California lemon law claim. Save every repair order from every visit, including the recall service records.
Yes, it is a confirmed safety recall. Recall 25V-606 (Hyundai Recall 282, September 2025) covers 31,042 Ioniq 6 vehicles from model years 2023 through 2025, produced between December 14, 2022 and December 26, 2024. The charging port door and its outer panel have retaining hooks that may not be sufficiently engaged during assembly. Inadequate adhesion causes the panel to separate from the vehicle body when exposed to air pressure at highway speeds. The detached panel becomes a road hazard for other vehicles. Six US detachment incidents were confirmed at the time of the recall filing; no crashes or injuries were reported. The remedy is adhesive application to the charging port door assembly, performed at the dealer at no charge. You can check whether your specific vehicle is included by entering your VIN at nhtsa.gov. If the charging port door has already detached from your vehicle and you have had other recall or defect-related service visits, this event may factor into a broader lemon law analysis.
Recall 26V-218 (Hyundai Recall 298, April 2026) covers 35,149 Ioniq 6 vehicles from model years 2023 through 2025, produced between December 14, 2022 and May 16, 2025. The front seat belt anchor uses a snap-on retainer clip that can be damaged when it is forcefully removed during routine maintenance or service — for example, during an oil check, interior repair, or any procedure requiring seat movement. Once the retainer clip is damaged, the seat belt anchor can detach from the seat frame. In a crash, a detached anchor cannot properly restrain the occupant, significantly increasing the risk of injury. The remedy — inspection and installation of a reinforcement insert in the retainer clip, or full anchor replacement — is performed at the dealer at no charge. Owner letters were mailed beginning May 29, 2026. Importantly, if your vehicle has had any dealer service work since purchase, the anchor may already be at risk. Ask your dealer to inspect the seat belt anchors on your next visit.
It may. California's Song-Beverly Consumer Warranty Act presumes a vehicle is a lemon when a safety defect has not been fixed after two or more repair attempts, or when any substantial defect persists after four attempts, or when the vehicle has been out of service for a cumulative 30 or more days during the warranty period. All days at the dealer — including parts-delay wait time and 'unable to duplicate' visits — count toward the 30-day threshold. For the Ioniq 6, the ICCU defect is the strongest basis for a claim: two separate recalls for the same safety-critical component, NHTSA confirmation that the first fix was insufficient, and ongoing post-recall failure reports. An owner who had the 24V-204 recall completed and then experienced another ICCU failure has documented multiple repair attempts on the same safety system. Combined with any other recall service visits — driveshaft, charging port door, seat belt anchors, Level 2 charging interruptions — the cumulative out-of-service days can add up quickly across this vehicle's five recall campaigns. Gathering your repair orders and consulting a California lemon law attorney is the right first step. If you prevail, Hyundai is responsible for your attorney fees.
