Known issues on the 2018 ILX. Three recalls are on federal record for this model year: a fuel pump failure that can cause an engine stall while driving and increase the risk of a crash; a brake master cylinder fault where reduced brake function can extend the distance required to stop; and a driveshaft separation that can cause a loss of drive or allow unintended vehicle movement. Owners have filed 25 complaints, and 49 technical service bulletins have been issued for the year. This manual carries the factory diagnostic and repair procedures behind each of those systems.
From a scheduled service interval on the 2.4L to a brake hydraulic repair or a half-shaft replacement, it keeps you on the OEM procedure and the correct specification for your specific 2018 ILX.
Acura (American Honda Motor Co.) is recalling certain 2014-2019 Acura ILX vehicles. The vehicles may have a deformed fuel tank, raising the height of the fuel pump and allowing the fuel level float to stick, possibly causing the fuel gauge to display an inaccurate fuel level.
If the fuel gauge displays that the vehicle has more gas than it actually does, the vehicle may run out of gas and stall, increasing the risk of a crash.
