Mazda has issued a recall for their CX-90 three-row crossover SUVs due to a software problem that could prevent the engine from restarting when the engine start-stop system is used. This recall specifically affects 2024 mild-hybrid models, totaling 38,926 vehicles. The mild hybrids feature small battery packs and electric motors that assist the gasoline motor, allowing for a more robust start-stop system.
The issue stems from “improper” software in the power control modules and battery energy control modules, which can disrupt the hybrid-assist function and lead to the gasoline engine stalling. If this occurs, a “Hybrid System Malfunction” message will appear in the instrument cluster, accompanied by warning chimes. Mazda has received seven field reports related to this issue, but no crashes or injuries have been reported as a result.
The remedy for this recall involves reprogramming both the power control module and battery energy control module, which will be done by dealers at no cost to the owners. Notification letters will be sent out on December 30, and owners can also contact Mazda customer service at 1-800-222-5500 for more information. The recall number for this issue is 7024J.
Despite the CX-90 earning an IIHS Top Safety Pick+ award in plug-in hybrid form, it has been the subject of multiple ongoing recalls. In addition to the start-stop system recall, Mazda also announced recalls for software issues in plug-in hybrid models that could result in a loss of propulsion, as well as a recall for instrument-cluster display issues.
It is important for affected Mazda CX-90 owners to take action promptly to address this software issue and ensure the safety and functionality of their vehicles. Mazda is committed to resolving these issues quickly and efficiently to maintain the quality and reliability of their vehicles.
