2021 Acura Ilx: Recalls, Complaints & California Lemon Law

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.

NHTSA #11725734

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.

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. The vehicle was involved in an accident on July 6, 2025 and delivered to Caliber Collision in Corpus Christi, Texas. All accident-related repairs have been completed. However, the vehicle cannot be released because a required airbag and/or airbag module is unavailable. 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 vehicle cannot be legally or safely released. The delay is no longer accident-related and is solely due to manufacturer unavailability of a safety-critical, non-cosmetic part. I have requested interim solutions including buyback, rental assistance, or a dealership loaner, and no temporary or permanent solution has been provided. This complaint is submitted to document manufacturer inability to supply a required safety component resulting in extended loss of vehicle use.

The contact owns a 2021 Acura ILX. The contact stated while attempting to park the vehicle, the airbag deployed without impact which resulted in the contact crashing into a pole. The contact sustained a hurt knee and headaches that required medical treatment. The vehicle was towed to a local dealer where it was awaiting repairs. The contact stated no warning lights were illuminated. The manufacturer was informed of failure and was awaiting a response. The failure mileage was approximately 2,000.

Allegedly reported: 1 injury (as reported to NHTSA). NHTSA #11447356

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.

It is Acura ILX 2021. The current mileage is 17,480. What component or system failed or malfunctioned, and is it available for inspection upon request? *Driveshaft/suspension is broken after inspection. How was your safety or the safety of others put at risk? *Intense shaking coming from underneath the vehicle. Worn out u-joints, couplers or carrier bearings can cause the driveshaft to vibrate and make noise when passing over bumps and potholes. If not fixed, it can lead to further damage to other drivetrain components. Has the problem been reproduced or confirmed by a dealer or independent service center? * Not sure for 2021 model. However, there is a recall history for model 2016-2019 Acura ILX. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? * The vehicle was inspected and waiting for remedy. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? * No there is no sign of warning. Due to extreme noise, the vehicle was inspected.

Electrical Failure. Safety was an issue with vehicle needing constant jumps. Problem was checked at dealer. My concern was continuously overlooked. Warning lamps didn't warn.

NHTSA #11498700

Vehicle suddenly decelerated without warning. Transmission would not shift to a higher gear causing the vehicle rev. Warning lights on the dashboard started going off at the same time. Lanes departure and adaptive cruise control warning went off. Had to have vehicle towed to dealership. Lucilky this happened on a rural backroad and not on the freeway or busy road as someone could have rear-ended the vehicle. Dealership was given video of incident and couldn't replicate the issue and we were told that the car did not store any of the error codes for the warning lights that came on the dash. The evening before the brake lights would not turn off when when the vehicle was turned off. Dealership said it was an adjustment that needed to be made to the switch on the brake pedal. Car is unsafe to drive as if this were to happen again on a busy highway or road without notice the persons behind would not be expecting the vehicle to suddenly drastically drop speed and not be able to accelerate.
