Number potentially involved: 635,808

Estimated percentage of involved with defect: 100%

Describe the defect or noncompliance:
An improper electronic power steering (EPS) software configuration may cause the EPS system to enter failsafe mode under certain operating conditions.

Describe the safety risk:
If the EPS system enters failsafe mode, power steering assist is disabled, and the EPS warning indicators illuminate in the instrument cluster. Without power assist, steering effort increases, which may reduce vehicle controllability, increasing the risk of a crash or injury.

Describe the cause:
The supplier developed incorrect EPS software containing an error in the Driver Attention Monitor road-condition compensation calculation and an improperly configured response to the resulting internal error. Under specific operating conditions, the software may perform a floating-point division with a zero denominator, triggering an internal error. The EPS software was incorrectly configured to respond to this error by disabling power steering assist.

Description of remedy program:
Registered owners of all affected vehicles will be contacted by mail and asked to take their vehicle to an authorized Honda or Acura dealer. The dealer will reprogram the EPS control unit with improved software.

How remedy component differs from recalled component:
The remedy component contains the correct EPS software.

Describe the recall schedule for notifications:
Dealer notification is scheduled to begin and end on or about 10/30/2026. Customer notification is scheduled to begin and end on or about 12/14/2026.
