According to the company's official representative, 294,612 vehicles will be inspected as part of the service campaign, including:
- Acura MDX Type S (model years 2022–2025),
- Acura TLX Type S (model years 2021–2025),
- Honda Pilot (model years 2023–2025).
The problem lies in an error in the software of the fuel system control unit. This can cause unpredictable behavior of the throttle valve, which in turn leads to loss of power or complete engine shutdown. Such a sudden failure while driving, especially at high speed, significantly increases the likelihood of a traffic accident.
The first signals of malfunctions reached Honda in December 2023 through the telemetry system. In April 2024, the component manufacturer Denso informed about possible defects in the software code. Final confirmation of the risk of sudden engine stalling occurred in January 2025. As it turned out during the investigation by the U.S. National Highway Traffic Safety Administration (NHTSA), the root of the problem is in incorrect parameters of the algorithm responsible for fuel supply and air flow adjustment.
No incidents with injuries or accidents caused by this defect have been recorded. However, the company has already received 674 complaints under warranty service.
To rectify the situation, Honda plans to update the software. This service will be provided free of charge, but will require a personal visit by the owner to an authorized service center — remote downloading of updates is not provided. Letters inviting owners to the procedure will begin to be sent on March 17, although dealer centers have already received all necessary instructions.
This recall campaign is one of the largest for 2025 and reminds of the growing role of software quality in the safety of modern cars.
