Hyundai has announced a recall of 54,337 units of the 2024–2026 Elantra Hybrid sedans in the US market. The issue is related to a defect in the Hybrid Power Control Unit (HPCU), which could pose a serious risk to the vehicle's technical condition. This is reported by Ixbt.com reports .
It has been determined that the MOSFET transistor in the HPCU is prone to overheating under high loads. In most cases, this causes the vehicle to fail to start or enter a limp mode. However, in rare instances, severe overheating can lead to localized thermal damage and even fire.
Investigations revealed that the problem is not in the hardware, but in the software. According to regulators, the control system fails to sufficiently cool the HPCU under load. The company began investigating this defect at the end of 2024 and, after several technical analyses, confirmed the recurring failure of this specific component.
To date, 4 incidents related to this defect have been recorded, with only one resulting in a fire. Fortunately, no injuries or traffic accidents have been reported. Hyundai plans to resolve this issue by updating the HPCU software, which will increase the efficiency of the cooling system.
As a reminder, there were previously reports of issues with Hyundai Tucson hybrids regarding unintended braking due to software errors. The South Korean brand is facing a series of technical malfunctions due to such "raw" software in its hybrid models.
