Loss of braking forceOpened October 23, 2025, closed May 21, 2026

On October 23, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25015 after receiving complaints concerning a loss of brake assist in 2019-2020 MY Acura ILX vehicles. These complainants alleged master cylinder failures resulting in soft pedal feel or the brake pedal intermittently going to the floor. These failures could result in extended braking distance increasing the risk of a crash. Honda found that residual plasticizer in the brake reservoir hose could contaminate the brake fluid. This contaminated brake fluid was then absorbed by the secondary cup seal, causing it to swell. Engine heat during operation could further expand the swollen seal, allowing brake fluid to pass. Brake fluid bypassing the master cylinder cup seals can reduce brake-pedal firmness and increase stopping distance. On April 08, 2026, Honda filed Recall 25V‑859, recalling all 2016-2020 MY Acura ILX vehicles produced from October 9, 2014, to January 29, 2020. Under the recall, the dealer will replace the brake master cylinder with redesigned inner cup seals made of a different material, providing improved sealing capability. In view of Honda filing Recall 25V‑859 addressing the subject of this investigation, ODI is closing this Preliminary Evaluation. the federal safety agency reserves the right to take additional action if warranted by future circumstances.

I am writing to formally raise a concern regarding the handling of a safety recall repair performed on my 2019 Acura ILX at Maus Acura of North Tampa. I initially brought my vehicle in to address a safety recall related to the brake master cylinder. As explained in the recall notice, the issue involved contamination of the brake fluid that could affect braking performance. The dealership proceeded with replacing the brake master cylinder, as expected. However, the situation became significantly concerning following the completion of the recall service: After the recall repair was completed, my vehicle would not start and had no power. The dealership later informed me that a voltage spike during battery installation damaged the PCM, requiring replacement. The PCM was subsequently replaced, and the vehicle was returned to me. In addition to this, I experienced further issues after retrieving my vehicle: My second key was no longer functioning, which required an additional visit to the dealership for reprogramming. More importantly, I am now experiencing a new issue that did not exist prior to the recall service: when I am stopped (for example, at a traffic light) and holding the brake pedal, the vehicle vibrates noticeably. This ongoing vibration is particularly concerning because: It began only after the recall repair and related work were performed. It affects the normal operation and comfort of the vehicle. It raises questions about whether the repair process may have introduced additional mechanical or engine-related issues. At this point, I am very concerned about the overall quality of the service performed and the series of problems that occurred immediately after what should have been a straightforward recall repair.

My 2019 Acura ILX (VIN: [XXX] , 69,349 miles) is experiencing severe, dangerous brake system failure directly matching Acura Safety Recall RN5 / the federal safety agency Campaign 25V859 (Brake Master Cylinder). The vehicle does not stop properly. Due to the hydraulic malfunction of the defective factory master cylinder, the brake pads are overheating and melting quickly. The vehicle is unsafe to operate on public roads.I contacted multiple authorized local dealerships, including Grubbs Acura in Grapevine, TX and Park Place Acura, and both confirmed they cannot perform the safety repair because the manufacturer has not provided the necessary recall parts. I escalated this urgent safety issue to American Honda’s corporate support line (1‑888‑234‑2138). A corporate supervisor called me back but failed to provide a resolution, an emergency parts allocation, or alternative safe transportation.The manufacturer is currently unable to supply critical safety remedy parts for an active, catastrophic brake failure, and they have refused to provide a temporary loaner or rental vehicle to mitigate the hazard. I am filing this urgent complaint because I am stranded with an undriveable vehicle due to a critical safety defect that the manufacturer cannot remedy.

My brake pedal randomly sinks to the floor. I have been close to rear ending the vehicle in front of me due to this issue. My car has been to the Acura dealership on three different occasions complaining of this issue but nothing was ever found. The tech was unable to replicate the issue.

Brakes sometimes do not work. Brake pedal is pressed down to the floor with no resistance sometimes. The brakes need to be pumped multiple times in order to stop. This is a huge safety concern and more more serious than any other recall that we’ve had on our vehicles.

Reporting intermittent brake failure, where brake sank to the floor on the first press without any effect of slowing the vehicle. Fortunately, in each instance, on the second press the brakes functioned normally and slowed the vehicle, so no accident or injury occurred. The first incident was in May 2022 after driving over a speed bump -- at the time I assumed user error and did not report the incident. The brakes failed a second time in March 2025 when descending a hill at 35 mph, and a third time in April 2025 after U-turning on a hill at low speeds. At that time, I opted to tow the car to the dealer for a repair. The dealer found no brake issues on inspection/testing, but after finding another case report recommended replacing the master cylinder. Of note, this is similar to the federal safety agency recall 23V‑458 for other Acura/Honda models from 2019/2020 where there were issues with the master cylinder, but the Acura ILX was not included. There was also a the federal safety agency Acura Service Bulletin 22-014 from 2022 advising of a search for Acura 2019 ILX vehicles with an intermittent brake issue. I have also attached my correspondence with Acura.
