Software error prompts recall of 256,000 Honda Accord Hybrid models

American Honda Motor Co. has initiated a voluntary safety recall for approximately 256,000 Honda Accord Hybrid vehicles from the 2023 through 2025 model years in the United States. The recall concerns a software-related issue involving the vehicles’ Integrated Control Module, referred to as the ICM. According to information released by the company, incorrect programming supplied by an external software vendor may cause the ICM to unexpectedly reset while the vehicle is in operation. Honda reports that if the module resets at speed, the vehicle may lose motive power, creating conditions that could increase the risk of a crash or potential injury.

The Integrated Control Module manages several core hybrid system functions. In modern Honda hybrid vehicles, including the Accord Hybrid, the propulsion system relies on continuous communication between multiple electronic control units. If a reset event occurs, the hybrid system may briefly stop processing the signals that coordinate propulsion, which can interrupt power delivery. Honda states that the loss of power can occur regardless of vehicle speed or driver input, depending on the timing and circumstances of the reset. The company did not cite any other mechanical or electrical defects outside of the software-level programming error.

Honda attributes the issue to improper programming carried out by a supplier. Although Honda did not name the affected supplier, the company indicates that the programming error was present during production of the recalled model years. Based on the currently available information, the programming flaw appears limited to the hybrid variant of the Accord and does not involve gasoline-only models. As a result, only Accord Hybrid vehicles from the 2023, 2024, and 2025 model years are included in this recall campaign.

The recall population covers vehicles distributed nationwide. American Honda reports that it will notify registered owners of recalled vehicles through mailed letters. These notifications will inform owners of the safety defect, advise them of potential symptoms, and provide instructions for scheduling service at an authorized Honda dealership. Customers will be asked to bring their vehicles to a dealer so that technicians can reprogram the Integrated Control Module with corrected software. The repair involves only software updates and does not require hardware replacement. Honda will perform the software reprogramming free of charge in accordance with federal safety recall regulations.

Although Honda states that mailed notifications will serve as the primary method of communication, owners do not need to wait for a letter to determine whether their vehicle qualifies. The company encourages owners to verify recall status online by entering their vehicle identification number (VIN) at the manufacturer’s recall website, located at www.recalls.honda.com. Alternatively, owners may call Honda’s customer service line at 888-234-2138 to confirm whether their vehicle is part of the recall and to receive further guidance on next steps.

No additional symptoms have been published to help owners detect the issue before a reset occurs. In many recent hybrid vehicles, powertrain control modules operate continuously, and software resets may not provide advance warning. For instance, loss of propulsion may manifest abruptly, even if other systems remain functional. Because the potential for sudden power loss presents clear operational concerns, Honda is advising owners to complete the recall remedy promptly once notified.

Honda’s announcement did not provide specific information regarding the number of incidents, complaints, or warranty claims associated with the software defect. The company’s statement also did not indicate whether any accidents or injuries had been reported in relation to the issue. Automakers often release limited initial information when a recall involves electronic control systems, especially when the fix consists of a software update rather than inspection or component replacement. As investigations progress, additional updates may become available through the National Highway Traffic Safety Administration (NHTSA) or future Honda communications.

Hybrid vehicles typically employ multiple layers of electronic oversight to ensure stable power delivery. The Integrated Control Module in the Accord Hybrid oversees interactions between the internal-combustion engine, electric motors, battery management systems, regenerative braking logic, and various driver inputs. A software reset could temporarily interrupt one or more of these systems, which in turn could affect acceleration or torque distribution. Even brief disruptions may cause the vehicle to enter a reduced-power state or cease propulsion until the system restarts. These characteristics underscore why Honda is conducting the recall despite the absence of mechanical failures or systemic electrical faults.

The recall impacts a single vehicle line but spans three consecutive model years. The 2023 and 2024 Honda Accord Hybrid models were the first to adopt the latest generation of Honda’s hybrid powertrain architecture, which emphasizes efficiency over plug-in capability. The 2025 Accord Hybrid is largely carried over structurally and mechanically, which explains why the software issue applies across multiple model years. While Honda did not specify whether the issue originated early in the development cycle or during updates made between production runs, the consistency across years suggests that the programming error persisted throughout that period.

Honda dealerships will utilize updated software provided by the company’s engineering teams. The reprogramming procedure is expected to be brief, although exact service times will vary by dealer and local workload. Because service centers may experience increased volume following recall announcements, Honda encourages customers to schedule appointments rather than arrive without a reservation. Dealers will not charge for the repair, as federal law requires safety recall remedies to be performed free of cost.

Owners who recently purchased a used 2023–2025 Accord Hybrid may not yet have their information registered with Honda. In these cases, the recall website or customer service phone line may provide the most direct method for determining whether the vehicle requires the software update. Buyers who recently transferred ownership may also request that Honda update its records to ensure they receive future notifications.

Honda’s communication emphasizes that the recall is intended to encourage owners to take corrective action as soon as they receive notice. Although the company did not issue any stop-sale or stop-drive advisories in the press release, the possibility of sudden power loss means that owners should schedule the repair promptly. Vehicles that have already received the updated software are not affected.

This recall is limited to the following U.S. vehicle population, with confirmation required through individual VIN lookup: the 2023, 2024, and 2025 Honda Accord Hybrid. Gasoline-only Accord models, Accords sold outside the U.S., and other Honda hybrid models are not included in the information provided.

Consumers seeking additional information may consult NHTSA’s database, which publishes recall reports submitted by automakers. Further updates may also be issued by Honda if new details emerge regarding the scope, cause, or remedy of the software error.
