Recall Date: 5/15/2026
NHTSA ID: 26V308
MFr. Campaign Number: 301
Manufacturer: Hyundai Motor America
Affected Components: Hybrid Power Control (HPCU) Software
Potential Number of Units Affected: ~54,337
Which Hyundai vehicles are affected?
The recall covers 2024-2026 Hyundai Elantra Hybrid vehicles assembled by Hyundai Motor Company in South Korea for sale in the U.S. The production window runs from October 31, 2023, through December 31, 2025.
Hyundai Mobis supplies the Hybrid Power Control Unit. Hyundai estimates that approximately 1% of the 54,337 vehicles in the population may exhibit the active defect.
What drivers need to know
The Hybrid Power Control Unit (HPCU) controls electrical power delivery to specific components of the hybrid system. The defect is in a metal-oxide semiconductor field effect transistor (MOSFET) within the HPCU. Under high electrical loads, the MOSFET can overheat. In most cases, the driver will experience a no-start condition or the vehicle will enter a reduced-power limp mode with the malfunction indicator lamp illuminated while driving. In limited cases, the HPCU can overheat enough to cause localized thermal damage to the assembly and internal components — which raises the risk of a fire.
Warning signs are present in most cases: a no-start condition or the MIL illuminating while driving. Either should be treated as a prompt to contact a Hyundai dealer rather than to continue operating the vehicle.
The remedy is an HPCU software update performed at a Hyundai dealer at no cost to the owner, regardless of warranty status. The new software improves MOSFET cooling and limits current delivery during vehicle operation. Owner notification is scheduled for July 13, 2026, and VINs have been searchable on NHTSA since May 16. Hyundai will reimburse owners for out-of-pocket expenses incurred to obtain a remedy for the recall condition per the reimbursement plan submitted to NHTSA on March 2, 2026.
Hyundai recall background
The investigation began on December 13, 2024, when Hyundai's North America Safety Office (NASO) opened a new investigation based on a Speak Up For Safety report involving a 2025 model year Elantra Hybrid in the U.S. The incident HPCU was recovered in February 2025 and forwarded to Mobis for teardown and root cause analysis in April.
Between June and July 2025, multiple Safety Testing & Investigation Laboratory teardowns confirmed a consistent MOSFET failure location across recovered parts, though damage severity varied and the failure wasn't externally visible. By late July, Hyundai's test data indicated that MOSFET failure could occur due to localized heating caused by high current load during vehicle ignition. In September, cold-start testing performed by the supplier confirmed that revised software parameters reduced localized heating at the previous failure points.
Between December 2025 and April 2026, NASO continued monitoring field information and recovering HPCUs. During that period, two new incidents were received indicating thermal damage localized to the HPCU. On May 7, 2026, Hyundai's North America Safety Decision Authority decided to conduct a safety recall. As of the decision date, Hyundai was aware of four incidents — including one fire — and no crashes or injuries related to the condition in the U.S. The new software was adopted as a production running change on January 7, 2026.

How BizzyCar can help
Fire-risk recalls move faster on social and earn higher response rates from owners — but only if the owner sees the notification in time. With dealer and owner notifications both scheduled for July 13, dealers have nearly two months from VIN searchability (May 16) to start identifying affected vehicles in their customer database. The Elantra Hybrid is also a younger population — most vehicles are still within warranty and still on a regular service cadence at the Hyundai franchise — which makes proactive outreach particularly effective.
BizzyCar's Recall Outreach product cross-references a dealer's customer database against open recall data to flag affected vehicles and initiate automated two-way SMS outreach. For Hyundai dealers, that means getting the Elantra Hybrid customer scheduled before July 13 — and reinforcing that the franchise service drive is the place to bring their hybrid in. Book a demo.
