Exterior Lighting · reported Mar 20, 2026
am reporting a serious safety defect in my 2021 Acura ILX involving the front headlight assembly. Water is entering the headlight housing due to what appears to be a manufacturer sealing defect, with visible condensation inside. This is causing electrical malfunction, including intermittent failure of the turn signal (blinker) and inconsistent headlight operation. The components are available for inspection upon request. This defect creates a significant safety hazard. The turn signal will fail to activate or activate randomly, preventing other drivers from knowing when I am changing lanes and…
Exterior Lighting · reported Mar 20, 2026
I am reporting a severe and hazardous safety defect in my 2021 Acura ILX involving water intrusion into the headlight assembly, resulting in electrical failure of critical lighting and signaling components.

As a result, surrounding drivers cannot…
Air Bags · reported Dec 19, 2025

Unknown or Other · reported Jul 30, 2024
My vehicle continues to accelerate when I press the gas pedal, and it sometimes makes clicking noises from underneath during acceleration. Occasionally, it veers to one side even when I keep the steering wheel straight. At times, it gives a warning and vibrates as if I'm merging into another lane. When I press the gas, the engine revs, but the car doesn't accelerate. Issues have been ongoing but dealership where I got the car from wants to charge me inspection fees per symptom.
