Honda has issued a widespread recall for more than a quarter-million Accord Hybrid vehicles manufactured between 2023 and 2025. This action is being taken due to a software flaw in the Integrated Control Module (ICM) that could lead to an abrupt cessation of motive power during operation. The manufacturer has documented over 800 related warranty claims, indicating the seriousness of this defect. Owners of the affected models will receive official notifications early in 2026, urging them to visit a dealership for a no-cost software update.
The issue at hand specifically targets the 2023 to 2025 models of the Honda Accord Hybrid. This mid-size sedan, despite shifts in consumer preferences towards SUVs, maintains a strong presence in the market, with its hybrid variants contributing significantly to sales figures. The National Highway Traffic Safety Administration (NHTSA) highlighted the defect, noting the potential for unexpected power loss that poses a safety concern for drivers.
An in-depth investigation revealed that the root cause lies within the software of the car's Integrated Control Module. Developed by Astemo Indiana, the software was found to misinterpret internal communication errors as critical CPU failures. Compounded by the ICM's role in managing various electrical functions, which adds to the system's load and electrical interference, these false readings can prompt an uncommanded CPU reset. Such a reset, while the vehicle is in motion, directly leads to the loss of drive power. Fortunately, no injuries have been linked to this problem so far, but the inherent risk prompted Honda to initiate this safety recall to mitigate potential dangers.
Honda initiated an inquiry into this matter in early 2024, pinpointing the cause by mid-2025. By late October 2025, an updated software version was finalized to address the vulnerability. Vehicles produced between November 11, 2022, and October 24, 2025, are included in this recall. The specific component identified is part number 5K800-30B-A060-M1. The manufacturer has since implemented the revised ICM CPU software in all new production vehicles.
For current owners, the resolution involves a straightforward process: a visit to an authorized Honda dealership. Technicians will then reprogram the Integrated Control Module with the updated software package, resolving the defect. Drivers can check their vehicle's eligibility using the Vehicle Identification Number (VIN) on Honda's recall website once the notification period commences. It is highly recommended that owners schedule this essential service as soon as they receive their recall notice to eliminate the risk of unexpected stalling and ensure continued safe operation of their vehicle.
