Hyundai Recalls Over 54,000 Elantra Hybrids Due To Overheating Risk
Table of Contents
Hyundai has issued a new recall for certain Elantra Hybrid sedans in the United States after identifying a problem with the hybrid power control unit, also known as the HPCU. The issue could cause the system to overheat under high electrical loads, which raises the risk of a fire and may also leave the car stuck in limp mode or unable to start.
According to documents filed with the National Highway Traffic Safety Administration, the recall affects 54,337 units of the 2024, 2025, and 2026 Hyundai Elantra Hybrid.
What Is Causing The Recall?
The problem comes from a component inside the hybrid power control unit called a MOSFET, short for metal oxide semiconductor field effect transistor. Under heavy electrical loads, this part can overheat if the software does not cool the system properly.
Hyundai says the current software installed in the affected vehicles may not provide enough cooling protection for the HPCU during certain driving conditions.
If overheating happens, the unit can suffer localized thermal damage to internal components and assembly parts.
That may lead to:
- Reduced power or limp mode
- Check engine warning light turning on
- Vehicle failing to start in some cases
- Increased fire risk in extreme situations
For hybrid owners, limp mode is basically the car’s way of saying, “Something is wrong, let’s not make it worse.” The vehicle keeps running, but performance drops heavily to protect the system.
Which Hyundai Elantra Models Are Affected?
The recall covers selected:
| Model | Model Years |
|---|---|
| Hyundai Elantra Hybrid | 2024 |
| Hyundai Elantra Hybrid | 2025 |
| Hyundai Elantra Hybrid | 2026 |
Not every Elantra Hybrid from these years is affected, but owners can check their VIN through Hyundai or the NHTSA recall database once notifications begin.
What Hyundai Will Do To Fix It
Hyundai dealers will update the HPCU software free of charge.
The updated software is designed to:
- Improve cooling performance for the MOSFET
- Reduce maximum current delivery under high loads
- Lower the chance of overheating in the future
The repair itself is software based, so owners should not expect major hardware replacement unless additional damage is found during inspection.
Hyundai also confirmed it will reimburse owners who already paid out of pocket to repair the issue before the recall announcement.
When Will Owners Be Notified?
Hyundai plans to notify dealers and affected vehicle owners by July 13, 2026.
Owners will receive instructions to schedule a dealership visit for the software update.
Hybrid Systems Are Getting More Complex
Modern hybrid systems deliver excellent fuel economy and smoother city driving, but they also rely heavily on advanced electronics and thermal management systems. When cooling software fails to react properly, even a small electronic component can create a much larger issue.
In this case, Hyundai appears to have caught the issue before reports of widespread incidents surfaced. A software update is also far less disruptive than a full component replacement, which should make the recall process quicker for most owners.

Hyundai Elantra Hybrid Recall FAQ
1Why is Hyundai recalling the Elantra Hybrid? ⌄
Hyundai is recalling certain Elantra Hybrid sedans because the hybrid power control unit, or HPCU, can overheat under high electrical loads. In some cases, that overheating can increase fire risk, trigger limp mode, or stop the car from starting.
2Which Hyundai Elantra Hybrid model years are affected? ⌄
The recall covers selected 2024, 2025, and 2026 Hyundai Elantra Hybrid models. Not every car from those model years is affected, so owners should check their VIN with Hyundai or the NHTSA recall database.
3How many vehicles are included in this recall? ⌄
According to the recall documents, 54,337 units are affected in the United States.
4What part is causing the overheating issue? ⌄
The issue comes from a component inside the HPCU called a MOSFET, which stands for metal oxide semiconductor field effect transistor. Hyundai says the current software may not cool the unit properly during certain driving conditions.
5What symptoms can drivers notice if the HPCU overheats? ⌄
Possible symptoms include reduced power or limp mode, a check engine light, and in some cases the vehicle may not start. In more serious cases, overheating can create a fire risk.
6How will Hyundai fix the recall? ⌄
Dealers will update the HPCU software free of charge. The updated software is designed to improve MOSFET cooling, reduce maximum current delivery, and lower the chance of overheating.
7Will Hyundai replace hardware in the affected cars? ⌄
The recall repair is software based, so a major hardware replacement is not expected unless a technician finds additional damage during inspection.
8When will owners be notified? ⌄
Hyundai plans to notify dealers and affected owners by July 13, 2026. Owners will then be told to visit a dealer for the free software update.
9Will Hyundai reimburse owners who already paid for repairs? ⌄
Yes. Hyundai says it will reimburse owners who already paid out of pocket to fix the issue before the recall was announced.
10Why do hybrid systems need careful software control? ⌄
Hybrid systems depend on advanced electronics and thermal management. If cooling software does not react properly, even a small component can cause a much larger problem, which is exactly why this recall matters.
