- Exterior lighting
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. Due to an apparent manufacturing defect in the headlight sealing, moisture is entering the housing and is visibly present as condensation, directly causing system malfunction. This defect leads to intermittent and unpredictable failure of the turn signal (blinker), including failure to activate and spontaneous activation without driver input. As a result, surrounding drivers cannot accurately determine my intended movements, significantly increasing the risk of a collision. Additionally,…

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 increasing the risk of collisions. The headlight also intermittently dims or shuts off at night,…

I am submitting this complaint regarding a 2021 Acura ILX (VIN: [XXX] ) that has been unreleasable for an extended period due to manufacturer inability to supply a required safety component.

American Honda Motor Company, Inc. has advised that the safety component is unavailable to be sold and that no estimated time of availability exists. Due to the safety nature of the missing component, the repair facility has confirmed the…

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.
