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.

UNKNOWN OR OTHER,LANE DEPARTURE
1 complaint
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.

Crash: 1
UNKNOWN OR OTHER
1 complaint
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.
