Hyundai is recalling 54,337 Elantra Hybrids from the 2024, 2025, and 2026 model years due to a hybrid system overheating issue that could lead to a fire, limp mode, or prevent the vehicle from starting. The recall affects a subset of Hyundai Elantra Hybrids equipped with a hybrid power control unit (HPCU) that contains a metal-oxide semiconductor field effect transistor (MOSFET), which can overheat under high electrical loads.
The issue with the hybrid system stems from the HPCU, which may not provide enough cooling to keep the unit from overheating. In cases of overheating, the HPCU could experience localized thermal damage to its assembly and internal components. Should overheating occur, the affected Elantras may put themselves into a reduced power or "limp" mode and illuminate the check engine light. In some scenarios, the affected models may not start.

Owners will be instructed to bring their vehicle to a dealership, where a technician will update the HPCU software for free. The updated software improves the MOSFET cooling and limits the maximum current delivery, reducing the chance of the unit overheating. The automaker will also reimburse any owners who paid out-of-pocket costs to fix the problem before the recall was implemented.
According to the National Highway Traffic Safety Administration (NHTSA) documents, the recall is a precautionary measure to prevent any potential accidents or injuries. Hyundai has not reported any accidents or injuries related to the hybrid system overheating issue.
