Of the 11 brakes complaints filed for the 2019 Acura ILX, here's the actual mileage breakdown — failures cluster heaviest at 0-25,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering brakes on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners report a dangerous intermittent brake failure: the brake pedal sinks to the floorboard with no resistance and the vehicle does not slow or stop. This happens unpredictably during normal driving—both forward and reverse, at low speeds and highway speeds. On second pump, brakes typically restore, which has so far prevented crashes, but owners describe close calls. One owner had the failure occur at 35 mph descending a hill; another at 45 mph exiting a highway.
No warning lights appear before failure. Multiple dealers have inspected these vehicles and cannot reproduce the issue during testing, even though one tech witnessed it happen during a test drive but could not identify the cause. One dealer added brake fluid without resolving the problem; another recommended master cylinder replacement after reviewing similar case reports.
Acura issued recall 25V-859000 (Service Brakes, Hydraulic) after these complaints, but parts have been on back order for months. A 2022 Acura Service Bulletin (22-014) advised searching for 2019 ILX vehicles with intermittent brake issues. A similar recall (23V-458) covered master cylinder problems in 2019–2020 Acura and Honda models, but excluded the ILX. One owner reports a dealership claimed the issue stems from air conditioning disrupting engine vacuum to the power brake system, yet no factory repair guidance exists for this.

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.
