Hyundai Recalls 54,337 Elantra Hybrids Over a Fire Risk

Hyundai is mailing recall notices this week to more than 54,000 Elantra Hybrid owners after finding a transistor inside the car’s hybrid power system can overheat under heavy electrical load, in rare cases sparking a fire.

What Is Wrong With the Elantra Hybrid

The recall covers 54,337 Hyundai Elantra Hybrid vehicles from the 2024 through 2026 model years, built between October 31, 2023 and December 31, 2025. The defect sits inside the hybrid power control unit, the component that manages electricity flow between the battery and the electric motor. A metal-oxide semiconductor field effect transistor, known as a MOSFET, inside that unit can overheat when the system is placed under high electrical load.

Hyundai estimates roughly 1 percent of the 54,337 vehicles in the recall population carry the active defect. In most cases, a driver will notice a no-start condition or the car will drop into a reduced-power limp mode with the malfunction indicator lamp lit on the dashboard. In a smaller number of cases, the overheating has been severe enough to cause localized thermal damage to the power control unit and surrounding components, raising the risk of a fire. Hyundai has confirmed four reported incidents tied to this defect, including one that resulted in a fire.

The Fix and the Timeline

Unlike many recent recalls that require a hardware replacement, Hyundai’s fix for this defect is a software update to the hybrid power control unit, performed free of charge at any Hyundai dealer. The software revision adjusts how the system manages electrical load to keep the transistor within a safe operating range.

Owner notification letters are scheduled to begin mailing July 13. The fix is software-based rather than a parts replacement, so dealers should be able to complete most repairs in a single service visit without waiting on parts to arrive, a faster turnaround than owners typically see with recalls involving physical components.

Part of a Broader Pattern at Hyundai This Year

The Elantra Hybrid recall is the latest in a string of Hyundai safety actions in 2026. In June, Hyundai recalled 96,310 Tucson, Tucson Hybrid, and Tucson Plug-In Hybrid models after finding the instrument cluster display could intermittently reboot while driving, temporarily blanking the speedometer and fuel gauge. Separately, Hyundai and sister brand Kia told owners of certain Ioniq 5 and EV6 models with 2023 and 2024 model year high-voltage batteries to park away from structures after identifying misaligned battery electrodes that can create an internal short circuit, with dealer notification letters for that issue going out July 6.

Hybrid and electric power electronics have become a more common source of fire-risk recalls across the industry as automakers push more hybrid and electric models into showrooms. The Elantra Hybrid case follows a familiar pattern: a component operating within its normal design range under everyday conditions, but failing to shed heat properly under the higher electrical loads that come with hard acceleration, sustained highway driving in hot weather, or stop-and-go traffic that cycles the hybrid system repeatedly.

Why the Power Control Unit Is Central to the Defect

The hybrid power control unit is one of the most electrically demanding components in any hybrid vehicle. It sits between the battery pack and the electric motor, converting and directing current at high speed every time the car accelerates, brakes regeneratively, or switches between gas and electric power. That conversion happens dozens of times over a typical drive, so the transistors inside the unit are engineered to handle repeated heating and cooling cycles without degrading. A transistor that overheats under high load, as Hyundai found in this case, represents a fundamental design or manufacturing tolerance issue rather than a part simply wearing out over years of normal use, which is why the fix here targets the software controlling electrical load rather than asking owners to replace the physical unit.

Conditions that place the heaviest load on a hybrid power control unit include hard acceleration from a stop, sustained highway driving in hot weather, towing, and stop-and-go traffic that repeatedly cycles the system between gas and electric power. Elantra Hybrid owners in warmer climates, or those who do a significant amount of stop-and-go city driving, may be somewhat more likely to encounter the symptoms Hyundai has described, though the defect can theoretically appear in any affected vehicle regardless of how or where it is driven.

A Growing Category of Hybrid and EV Fire Recalls

As automakers sell more hybrid and electric vehicles, fire-risk recalls tied to power electronics and battery systems have become a larger share of overall recall activity across the industry, a shift that reflects both the newer technology involved and the intense electrical loads these systems handle compared to a traditional gas engine. Traditional combustion vehicles rarely see recalls tied to overheating semiconductors, given they do not rely on power electronics to move the car. Hybrid and electric vehicles do, and as the vehicle population shifts further toward electrified powertrains, drivers should expect this category of recall to remain a regular feature of automotive news rather than a rare event.

What Elantra Hybrid Owners Should Do

Owners of a 2024 through 2026 Elantra Hybrid should check their vehicle identification number now at nhtsa.gov/recalls rather than waiting for the mailed notice to arrive, as letters can take one to two weeks to reach owners after mailing begins. The VIN lookup will confirm immediately whether a specific vehicle falls within the affected build window.

Drivers who experience a sudden loss of power, a car that will not start, or a malfunction indicator lamp illuminating on the dashboard should have the vehicle inspected by a Hyundai dealer as soon as possible rather than continuing to drive on the assumption the issue will resolve itself. Given that Hyundai has confirmed at least one fire linked to this defect, any unusual smell of burning plastic or electrical components from the engine area warrants pulling over and shutting the vehicle off immediately.

Owners can schedule the free software update at any Hyundai dealer once notified, and do not need to wait for a specific appointment slot tied to their notification letter. Calling ahead to confirm the dealer has the current software package ready to install can help avoid a wasted trip, especially in the days immediately after notification letters go out and demand for the fix spikes.

Where to Get Help

Hyundai owners with questions about this recall can contact Hyundai customer service directly or reach out through their local dealer’s service department. For general recall information across any make or model, NHTSA’s Vehicle Safety Hotline at 1-888-327-4236 can confirm open recalls and provide guidance on next steps. Drivers can also sign up for free VIN-based recall alerts through NHTSA’s SaferCar app, which notifies owners as soon as a new recall is filed rather than waiting for a mailed letter.

With three separate safety actions tied to hybrid and electric power systems in the past month alone, Hyundai owners across multiple model lines have reason to check their VIN this week even if they have not yet received a notification letter in the mail.

Hyundai has not indicated that this recall will affect the Elantra Hybrid’s fuel economy, driving performance, or warranty coverage once the software update is installed. The company has also not announced any plans for a temporary loaner vehicle program tied to this specific recall, unlike the park-outside instructions issued for some other automakers’ battery fire recalls this year, as Hyundai’s guidance for the Elantra Hybrid does not restrict where or whether owners can continue driving the vehicle before the software fix is applied. Owners who are uneasy about continuing to drive before the update is installed can still request an expedited service appointment by explaining the recall notice number to their dealer’s service advisor when scheduling.
