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, the headlight intermittently dims or shuts off at night, creating dangerously reduced visibility and unsafe driving conditions. The defect also compromises essential driver-assist safety systems, including blind spot monitoring and lane departure warning, which rely on consistent visibility and signaling. When these systems are impaired, the risk of unsafe lane changes and crashes is substantially elevated. The issue is ongoing, reproducible, and worsens with normal environmental exposure such as rain or humidity. There were no prior warnings. The failure began with visible condensation and has progressed into repeated electrical malfunction affecting multiple safety-related systems. This is a failure of federally required safety equipment, not a cosmetic issue. Loss of lighting, signaling, and safety system reliability presents a clear and unacceptable risk of crash, injury, or fatality. This defect does not appear isolated and may indicate a systemic manufacturing or design failure. Immediate investigation is necessary, and recall action is warranted to prevent further harm to drivers and the public.

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, reducing visibility and creating dangerous driving conditions. This issue also affects driver-assist safety systems, including blind spot monitoring and lane departure warning, which rely on proper signaling and visibility. When the lighting system malfunctions, these systems are less effective, increasing the risk of unsafe lane changes. The problem is ongoing and reproducible, especially after exposure to moisture. The malfunction occurs intermittently but frequently enough to make the vehicle unsafe. The vehicle has not yet been formally inspected, but inspection is being pursued. There were no warning lights prior to failure. The first symptom was condensation inside the headlight, followed by increasing failure of the blinker and headlight. This does not appear to be an isolated issue and may indicate a broader manufacturing defect. Because this directly impacts visibility and signaling, it is a critical safety concern. This issue should be urgently investigated for a recall to prevent accidents, injuries, or fatalities.

My vehicle continues to accelerate when I press the gas pedal, and it sometimes makes clicking noises from underneath during acceleration.

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.
