Owner report 11725734 · 2026-03-20 (March 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.

Owner report 11605515 · 2024-07-30 (July 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.
