I am filing this complaint regarding the inadequacy of American Honda's recall remedy under NHTSA Campaign 25V-859 (Acura Campaign RN5) for my 2016 Acura ILX (109,000 miles). This recall addresses a defective brake master cylinder that can reduce braking performance and increase stopping distances, posing an unreasonable risk of crash or injury. Despite this acknowledged safety defect, American Honda is refusing to perform the recall repair, stating that parts are limited and repairs are being prioritized only for vehicles already exhibiting symptoms of failure. My case (#16165247) has been closed with no remedy provided. I have contacted American Honda approximately five times over the past two months and receive the same answer. No repair, no loaner vehicle, no interim safety guidance, and no timeline for parts availability has been offered. Their guidance was "we can prioritize your repair once you notice your brakes begin to fail." My local Acura dealer was uncooperative, stating they have no parts and telling me to get American Honda to provide parts, placing the burden of obtaining them on me as the consumer. The defect symptoms (degraded braking and increased stopping distances) mean the vehicle is already unsafe by the time failure is detectable. Requiring owners to continue operating vehicles with a known braking defect until failure occurs exposes my family, including young children, to the exact crash risk this recall was issued to prevent. It's negligent and endangers the consumer due to failure of the manufacturer. I am requesting that NHTSA open a Recall Query into Honda's handling of 25V-859 and exercise its authority under the Safety Act to compel American Honda to either expedite the recall repair on my vehicle or provide a manufacturer-funded replacement vehicle or rental until the remedy is completed. The recall remedy is not being provided within a reasonable time, and no adequate interim safety measures have been offered.

I am reporting a safety concern involving my vehicle, a 2016 Acura ILX (VIN: [XXX]), which is currently subject to an active brake system safety recall involving the brake master cylinder (Acura Recall Code RN5). The recall describes a defect in which contamination of the brake fluid system may cause the master cylinder seal to swell and reduce braking pressure, allowing the brake pedal to travel toward the floor and increasing stopping distance. The failure condition described in the recall is currently occurring in my vehicle. When braking, the brake pedal travels significantly toward the floor before the vehicle stops, which raises serious safety concerns regarding the ability to stop the vehicle in normal traffic conditions. I began contacting Acura dealerships in December 2025 after receiving the recall notice. I was informed that the required recall repair parts were not yet available and that I would be contacted when parts became available. Multiple dealerships in Massachusetts and Connecticut provided the same information. As of March 2026, I have not been contacted by any dealership regarding repair availability, and the vehicle continues to exhibit the braking condition described in the recall notice. Because the defect affects the braking system, I do not feel the vehicle can be safely operated while awaiting the recall repair. The vehicle remains financed and insured and is relied upon for daily transportation. This complaint is being submitted to document that the recall defect appears to be actively occurring in the vehicle and that the recall remedy has not yet been made available after several months.
