NHTSA 5-Star Safety Rating
Complaints for the 2017 Acura ILX are relatively sparse at 20 total, but brakes draw the most attention. Owners most commonly report abnormal noises when pressing the brake pedal, and several mention that dealers have confirmed a problem but can't complete repairs due to unavailable parts. The powertrain accounts for a handful of reports as well, though the described symptoms are less consistent across those filings. Outside the main systems, a single report describes the dash illuminating and the alarm triggering while the car is off, tied to the keyless access system. The parts availability issue appears across multiple brake-related reports, with owners noting they've been told repairs are on hold pending stock that isn't expected until well into 2026.

By System
The 2017 Acura ILX has 5 recalls, the most serious involving the driveshaft, which can separate from the half shaft while driving and cause an immediate loss of drive power or allow the car to roll even when shifted into Park.
On the fuel system side, two recalls share the same underlying problem: a deformed fuel tank can raise the fuel pump and cause the fuel level float to stick, making the gauge read higher than the actual fuel level. A driver who trusts that reading may run out of fuel unexpectedly, stalling the car in traffic. A separate fuel pump recall covers a broader range of Honda and Acura models, including this one, where the pump can fail outright and stall the engine while driving.
The brakes also have a concern: contaminated brake fluid can cause a seal inside the brake master cylinder to deform and leak internally. When that happens, brake pressure drops and the car takes longer to stop than the driver expects, which can make it difficult to avoid a collision in a sudden stop situation.
