What is the 2013-2022 Acura ILX In-Tank Low-Pressure Fuel Pump Impeller Failure Causing Engine Stall?
The Denso-supplied in-tank fuel pump module fitted across virtually the entire ILX production run uses an impeller that was molded with insufficient density and inadequately dried. The impeller absorbs fuel, swells, and interferes with the pump body. The pump then fails to delive… Repairs typically run $0-$0. Severity: high.
What is the 2013-2015 Acura ILX Driveshaft Coating Failure and Corrosion Fracture (Salt Belt) - Recall 20V770?
On early ILX built through the 2015 model year, the protective paint coating applied to the driveshafts was improperly manufactured. The coating peels and chips near the dynamic damper, exposing bare steel. In Salt Belt states, road de-icing salt attacks the exposed shaft and cor… Repairs typically run $0-$0. Severity: high.
What is the 2013-2016 Acura ILX Takata Driver Frontal Airbag Inflator Rupture (Multiple Recall Waves)?
The ILX was swept into the Takata ammonium-nitrate inflator recalls in several successive waves. The driver frontal airbag inflator propellant degrades with long-term exposure to high heat and humidity cycling, which can cause the inflator housing to over-pressurize and rupture d… Repairs typically run $0-$0. Severity: high.
What is the 2013-2014 Acura ILX IMA Hybrid Battery Module Degradation and Failure (2013-2014 ILX Hybrid, 1.5L)?
The ILX Hybrid used the Civic Hybrid's Integrated Motor Assist system - a 1.5L engine with a thin motor-generator between engine and CVT and a nickel-metal-hydride IMA battery pack. It sold in tiny numbers for only two model years and was dropped after 2014. The IMA pack degrades… Repairs typically run $2,000-$4,000. Severity: high.
What is the 2013-2014 Acura ILX Halogen Projector Headlight Assembly Overheating and Melting - Recall 14V323?
The original halogen projector-beam headlight assemblies on the earliest ILX build months do not vent enough heat. When the car sits with the engine running and low beams on for an extended period - idling in a parking lot, warming up, waiting in a pickup line - heat accumulates… Repairs typically run $0-$0. Severity: high.
What is the 2013-2015 Acura ILX Six-Speed Manual Clutch Release Bearing Growl and Engagement Grind (2013-2015 2.4L)?
The 2013-2015 ILX 2.4L was sold ONLY with a six-speed manual - an unusual configuration for a luxury-badged compact sedan, and it shares its clutch, gearset and transmission with the contemporary Civic Si. Owners report a distinct grinding or growling noise the moment the clutch… Repairs typically run $1,000-$2,000. Severity: medium.
What is the 2013-2022 Acura ILX VTC Actuator Cold-Start Rattle (2.4L K24 Only)?
On the 2.4L K24 ILX, the variable timing control (VTC) actuator on the intake camshaft is not fully oil-pressurized at first start. The internal locking pin fails to hold the actuator against the sprocket, so for one to two seconds after a cold start the actuator rattles loudly a… Repairs typically run $500-$1,000. Severity: medium.
What is the 2014-2019 Acura ILX Deformed Fuel Tank Causing Inaccurate Fuel Gauge and Unexpected Fuel Starvation - Recall 19V052?
On a range of ILX built from the 2014 model year onward, the plastic fuel tank was manufactured out of specification and can deform. The deformation changes the geometry the level sender float travels through, so the fuel gauge reads higher than the actual fuel remaining. Drivers… Repairs typically run $0-$0. Severity: medium.
