What's wrong?
The hybrid power control unit, or HPCU, is the electronic module that manages power flow in the hybrid drive system. In a 2024-2026 Hyundai Elantra Hybrid, it helps coordinate electrical power used for propulsion so the gasoline engine and hybrid components work together. The recalled part is the HPCU reservoir module, which is part of that power-control assembly.
On affected Elantra Hybrid vehicles, the HPCU assembly is at risk of overheating. Heat in this module matters because the hybrid drive system depends on stable power control while the vehicle is running. When the assembly gets too hot, it no longer has the normal operating margin Hyundai designed into the propulsion system.
There is no warning sign before failure. If your Elantra Hybrid is included in this recall, do not wait for a dashboard message, sound, smell, or drivability change before arranging the free dealer repair.
Who's affected?
All listed model years point to the same electric propulsion system component.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific sedan is included.
What's the safety risk?
Overheating in the HPCU increases the risk of a fire. If your VIN is included, schedule the software update as soon as Hyundai makes it available and ask the dealer for any interim instructions before your appointment. Repair will be free at any franchised Hyundai dealer once available.

What happens at the repair
At the dealer, a Hyundai technician will update the hybrid power control unit software. That is the known final repair path, and the dealer repair will be free once Hyundai opens the campaign for service. The software update is meant to address overheating in the HPCU assembly on affected 2024-2026 Elantra Hybrid vehicles. Owner notification letters are expected to be mailed July 13, 2026. Until then, keep any recall paperwork with the vehicle and ask a Hyundai dealer when the software update is available for your VIN.
