- More than 17,000 RDX SUVs recalled due to faulty steering software programming.
- Incorrect EPS gain setting can trigger failsafe when sharp steering inputs are applied.
- Dealers will reprogram the EPS memory layout and notify owners starting October 20.
More than 17,000 Acura vehicles are being recalled in the United States after an issue with the electronic power steering system was found to trigger a failsafe mode. While no injuries or fatalities have been linked to the defect, Acura has received 84 warranty claims connected to the problem.
The issue surfaced during software development for the 2025 RDX, when supplier JTEKT North America Corporation mistakenly set the steering system’s returnability setting, known as the Integrated Dynamics System gain, to the wrong value. The software adjustment was intended to meet California’s Idle Stop requirements but ended up creating an unintended glitch.

To put that in layman’s terms, Acura says that if the IDS is in Comfort mode, the Lane Keeping Assist System is active, and the driver applies a sharp steering input during a turn, the electric power steering system may detect a fault and enter a failsafe mode.
Which Cars Are Affected
A total of 17,344 RDX facelifted models from the 2025 model year are impacted, all of which were manufactured between January 23, 2024, and August 18, 2025. Just 0.3 percent of the vehicles being recalled are believed to have the defect.
Honda began investigating the fault in October last year and, throughout 2025, has been working with the supplier to analyze the root cause. As mentioned, the brand has had 84 warranty claims related to the issue from August 14, 2024, to August 28, 2025.
Dealerships were notified of the recall last week, and owners will receive letters beginning October 20. Authorized Acura dealers will reprogram the electronic power steering memory layout with updated software, which Acura says will fully resolve the problem.
