Honda Recalls 635,000 Vehicles Over Power Steering Software Defect

Honda Motor Canada and Acura have announced a recall affecting 635,808 vehicles in North America, including Canadian registrations. The issue: a software flaw in the electric power steering (EPS) system can cause the steering assist to abruptly disable while the vehicle is in motion, increasing the risk of a crash. The recall was first reported by multiple outlets on November 11–12, 2026.

What the defect does

The electric power steering system uses a software module to manage assist torque. In affected vehicles, a software error can cause the EPS to lose assist function suddenly. The driver does not get a warning before the assist drops — the steering wheel becomes significantly heavier with no advance notice. At low speeds (parking, urban driving) the effect is noticeable but manageable. At highway speeds, a sudden loss of power steering assist in a sharp manoeuvre can be dangerous.

Which models are affected

The recall covers both Honda and Acura lineups. Specific model years and trims are detailed in the NHTSA recall notice. Canadian owners of recent Honda and Acura vehicles should check their VIN against the NHTSA recall database once the campaign number is published. The 635,808 figure represents the total North American population affected, with Canadian registrations making up a portion of that total.

What the fix involves

The corrective action is a software update to the steering control module. Dealers will perform the update free of charge. Because this is a software fix, the repair is expected to be a relatively quick dealer visit — no hardware replacement is indicated in the initial reporting. Owner notification letters are expected to follow in the coming weeks.

What Canadian owners should do

If you drive a recent Honda or Acura with electric power steering, monitor your VIN on the NHTSA.gov recall database and check for your dealership's recall notification. In the interim, be aware of the symptom: a sudden, unexplained increase in steering effort with no dashboard warning. If it happens, pull over safely and have the vehicle inspected. The software defect is not progressive — it is an intermittent fault — so a single episode does not guarantee a repeat, but it does indicate the vehicle is in the affected population.
