Honda recalls 256K cars nationwide over potentially dangerous software glitch

Core Viewpoint - Honda is recalling approximately 256,000 Accord Hybrid vehicles in the U.S. due to a software glitch that may lead to a loss of power while driving, increasing the risk of accidents or injuries [1][2]. Group 1: Recall Details - The recall affects specific Honda Accord Hybrids from the 2023 to 2025 model years [1]. - The National Highway Traffic Safety Administration (NHTSA) reported that the integrated control module (ICM) may reset while driving due to a software error, resulting in a loss of drive power [2][5]. - Honda will reprogram the software at no cost to the vehicle owners to address the issue [2]. Group 2: Cause of the Issue - The problem originates from improper software programming by a supplier, which caused the ICM to reset while the vehicle is in motion [5]. - The supplier did not fully understand the intended functionality of the ICM, leading to misinterpretation of normal internal communication issues as serious CPU problems [5]. - Additional features added to the ICM increased electrical load and created more electrical "noise," exacerbating communication disruptions and causing unnecessary system resets that could shut down critical functions, including engine power [8]. Group 3: Warranty Claims and Notifications - As of November 6, Honda had received 832 warranty claims related to the defect, but there have been no reports of injuries or fatalities from December 2022 to October 2025 [12]. - Owner notification letters are scheduled to be mailed on January 5 [10].
