Estimated percentage of involved with defect: 0.27%

Describe the defect or noncompliance:
An improper electronic power steering (EPS) software calibration may cause the EPS system to enter failsafe mode under certain vehicle 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:
During development of the 2025 Acura RDX EPS software to comply with California Idle Stop OBD requirements, the Tier 2 supplier inadvertently set the EPS target returnability Integrated Dynamics System (IDS) gain to an incorrect value. Under certain driving conditions—specifically, when the driver applies a sharp steering input during a turn while the IDS is in Comfort mode and the Lane Keeping Assist System (LKAS) is active—this calibration can cause the EPS target returnability output to exceed the Safety Barrier threshold. When this occurs, the system may incorrectly detect a fault and enter failsafe mode.

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

How remedy component differs from recalled component:
The remedy software will not cause the failsafe to activate under the specified conditions.

Identify how/when the recall condition was corrected in production:
The supplier developed and implemented the improved EPS software into production on August 29, 2025

Dealer notification is scheduled to begin and end on or about 9/6/2025. Owner notification is scheduled to begin and end on or about 10/20/2025.

Date when VIN will be searchable: 9/17/2025
