5/5 Overall
NHTSA 5-Star Safety Rating
For the 2018 Acura ILX, the bulk of complaints center on the fuel and propulsion system. Owners most commonly describe the engine stalling, losing power, or the vehicle failing to move under its own power, in several cases requiring engine replacement. Some report that problems persisted even after repairs, with warning lights returning and the vehicle breaking down again. A smaller cluster of complaints touches on the engine more broadly, with owners noting rough running and multiple dashboard warning lights illuminating together. One isolated report describes steering and suspension symptoms, vibration, pulling to one side, and unusual front-end noise at low speeds, though that account stands alone and doesn't reflect a pattern across multiple complaints. Parts availability delays are mentioned by more than one owner as compounding the repair experience.

By System
The 2018 Acura ILX has 4 recalls, the most serious involving a driveshaft that can separate while driving, causing sudden loss of drive power or allowing the vehicle to roll even when shifted into Park.
On the fuel and braking side, the fuel pump can fail and stall the engine without warning while driving. The brake master cylinder has a separate concern: contaminated brake fluid can deform an internal seal, causing a fluid leak inside the cylinder that reduces braking force and extends stopping distances. There is also a fuel gauge issue where a deformed fuel tank raises the fuel pump assembly enough to cause the float to stick, making the gauge read higher than the actual fuel level and potentially leaving the driver unaware the tank is nearly empty until the engine stalls.
