What can fail
Contaminated brake fluid can warp a seal in the brake master cylinder, allowing fluid to leak internally and reducing your braking power.

5/5 Overall
NHTSA 5-Star Safety Rating
The 2019 Acura ILX draws the most complaints around its fuel system and brakes. The fuel system accounts for the largest share of reports, though the available narratives don't detail specific symptoms consistently enough to identify a tight pattern. Brake complaints are the clearer story: owners describe the vehicle not stopping properly, and several reports point to issues with the hydraulic brake system, specifically the master cylinder. Owners describe brake pads overheating and wearing out faster than expected, which they connect to the hydraulic components not functioning correctly. A smaller number of reports mention the brake assist or automatic braking system activating unexpectedly during low-speed maneuvers, including a case where the vehicle reportedly engaged its collision avoidance system while reversing with no obstacle present, then shifted and accelerated on its own.

By System
The 2019 Acura ILX has 5 recalls, the most serious involving a driveshaft that can separate from the half shaft, causing sudden loss of drive power or allowing the vehicle to roll even when shifted into Park.
Two recalls cover fuel pump failure, where the low-pressure pump inside the fuel tank can stop working and cause the engine to stall without warning while driving. Prior repair attempts in an earlier campaign did not fully resolve the issue, which is why a second filing covers some of the same vehicles. On the braking side, contaminated brake fluid can cause a seal inside the brake master cylinder to deform and leak internally, reducing the hydraulic pressure available to the brakes and extending the distance needed to bring the vehicle to a stop. Separately, a deformed fuel tank can raise the position of the fuel pump enough that the float responsible for measuring fuel level gets stuck, causing the fuel gauge to read higher than the tank actually is. A driver relying on that reading may unknowingly run the tank dry and stall on the road.

What can fail
Excessive grease on the half shaft's set-ring may prevent it from fully engaging, which can cause the driveshaft to separate from the half shaft.

What can fail
The fuel tank may be deformed, pushing the fuel pump higher and causing the fuel level float to stick. This makes the fuel gauge show an incorrect fuel level.
