Honda has launched a major U.S. recall covering more than a quarter-million Accord Hybrid vehicles after regulators identified a software malfunction that could cause the cars to lose drive power unexpectedly. The recall, documented by the National Highway Traffic Safety Administration (NHTSA), applies to certain models manufactured between 2023 and 2025.
The automaker says the issue affects a small percentage of vehicles but acknowledged that improper software programming can cause part of the hybrid control system to reset while the car is in motion, raising the risk of a crash.
Background on the Recall
Honda is recalling 256,603 Accord Hybrids after investigations confirmed that specific units may experience a sudden loss of propulsion due to a defect affecting the integrated control module’s central processing unit. NHTSA reports indicate that the error can cause an unexpected system reboot, which may briefly cut drive power before recovering.
Honda stated that the problem originates from “improper software programming by a supplier,” which left certain hybrid models vulnerable to mid-drive resets. The company said dealers will reprogram the software at no cost to owners, and updated software is already available nationwide.
Owner notification letters are expected to be mailed on January 5, according to NHTSA filings, but Honda confirmed the remedy can be accessed immediately through authorized service centers.
Details From the NHTSA Report
NHTSA recall documents note that the issue affects the Accord Hybrid’s integrated control module (ICM), a key component responsible for coordinating the hybrid system, regenerative braking, and engine-battery transitions. If the ICM resets without warning, the car can temporarily lose power, creating a hazardous situation in traffic.
Although Honda estimates that only 0.3% of recalled vehicles exhibit the defect, the scope of the recall reflects the potential severity of unexpected drivetrain loss. The safety agency has not received any crash or injury reports linked to the malfunction as of its latest update.
Honda told NHTSA that it began receiving field reports describing unusual system behavior in March 2024 and initiated a formal investigation shortly after. By November 6, the company had processed 832 warranty claims related to similar symptoms across the model lineup.
How Honda Responded
Honda says it worked with the supplier to identify the programming flaw and began developing a corrected version of the hybrid control software in 2024. The company completed internal testing and provided dealers with updated programming tools ahead of the public recall announcement.
The automaker emphasized that the software fix does not require parts replacement and can be completed during a standard service appointment. Honda owners can schedule repairs immediately through retailers, although they may still receive formal notification by mail in January.
American Honda also urged owners to verify whether their vehicle identification number (VIN) is included in the recall. Consumers can check their status through the NHTSA recall database or the company’s own recall lookup tool, both of which offer real-time updates.
Understanding the Impact on Honda’s Hybrid Line
The Accord Hybrid is one of Honda’s best-selling electrified models in the United States, contributing significantly to the company’s strategy for fuel-efficient and low-emissions vehicles. Hybrid sales have grown steadily across the industry, and the Accord Hybrid has been a key competitor in the midsize sedan market.
Software-related recalls have become more common as modern vehicles integrate complex electronic systems across safety, propulsion, and driver-assistance technologies. According to NHTSA data, electronics issues account for a growing share of U.S. automotive recalls, reflecting the rising reliance on software-controlled components.
While the defect does not appear to affect the gasoline-only versions of the Accord, the recall underscores the importance of reliability in hybrid system architecture, where electric and combustion powertrains must coordinate seamlessly.
What Affected Owners Should Do
Honda advises owners of affected vehicles to:
• Check their VIN using the NHTSA recall tool or Honda’s official lookup page.
• Contact a local Honda dealer to schedule a free software update.
• Pay attention to unusual vehicle behavior, including power fluctuations or dashboard warnings.
Customers can also reach Honda’s customer service line at 1-888-234-2138 for more information.
The recall remains open nationwide and will continue until all impacted vehicles receive updated software. Honda says additional notices or advisories will be issued if new information emerges.
