Honda Recalls 635,808 Vehicles Over Power Steering Software Defect

The recall includes 383,110 Honda Pilot SUVs from model years 2023 through 2025, 177,100 Acura MDX SUVs from 2022 through 2024, and 75,598 Acura TLX sedans from 2021 through 2025. The defect involves electronic power steering software developed by supplier Robert Bosch Automotive Steering LLC.

Honda said an error in a calculation linked to the Driver Attention Monitor can, under certain driving conditions, put the steering system into failsafe mode. That shuts off power steering assistance and turns on warning indicators. Drivers can still steer, but the wheel takes more effort to turn, which could make the vehicle harder to control and raise crash risk.

As of October 22, Honda had received 146 warranty claims and reports of one injury connected to the issue. The company said it had no reports of deaths related to the defect.

Honda first received a report of the problem in November 2021. In August 2025, the supplier pinpointed the malfunction, and Honda replicated it in December 2025. In February 2026, the company confirmed the issue could occur under certain conditions while a vehicle was traveling straight. Honda decided on October 22, 2026, that the defect posed a safety risk and warranted a recall.

Owners will be asked to bring affected vehicles to an approved Honda or Acura service center, where staff will install revised programming in the electronic power-steering controller. Honda plans to mail notification letters beginning December 14, 2026. Owners can check their vehicle identification number through NHTSA’s recall lookup site.
