Service brakes

9 reports
“I am writing to formally raise a concern regarding the handling of a safety recall repair performed on my 2019 Acura ILX at Maus Acura of North Tampa. I initially brought my vehicle in to address a safety recall related to the brake master cylinder. As explained in the recall notice, the issue involved contamination of the brake fluid that could affect braking performance. The dealership proceeded with replacing the brake master cylinder, as expected. However, the situation became significantly concerning following the completion of the recall service: After the recall repair was completed, my vehicle would not start and had no power. The dealership later informed me that a voltage spike during battery installation damaged the PCM, requiring replacement. The PCM was subsequently replaced, and the vehicle was returned to me. In addition to this, I experienced further issues after retrieving my vehicle: My second key was no longer functioning, which required an additional visit to the dealership for reprogramming. More importantly, I am now experiencing a new issue that did not exist prior to the recall service: when I am stopped (for example, at a traffic light)…”

Forward collision avoidance

3 reports
“The contact owns a 2019 Acura ILX. The contact stated that while driving 50 MPH downhill, the vehicle accelerated unintendedly and was pulling from side to side. The contact firmly held the steering wheel to keep the vehicle in the intended lane. Additionally, the contact depressed the brake pedal simultaneously, but the vehicle hesitated to respond, causing the braking distance to be extended. The contact was able to pull over to the side of the road. The messages "Collision Mitigation Braking System Problem", "High Beams Problem", "Lane Departure Failure", and "Adaptive Cruise Control Failure" were displayed. The contact was able to drive to the residence. The vehicle was taken to an Acura dealer, where it was diagnosed that the sensing system cameras needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 33,000.”

Fuel/propulsion system

3 reports
“To Whom It May Concern: I am writing to express my serious concerns regarding the safety recall (NHTSA Recall No. 21V-215) for the fuel pump on my 2019 Acura ILX, VIN [XXX] . While I appreciate that American Honda has issued this recall, I am deeply troubled by the lack of available replacement parts and the company's decision to prioritize repairs only for vehicles currently experiencing symptoms. This approach fails to adequately address the safety risks for all affected vehicles and owners. The recall notice clearly states that the defective fuel pump impeller can deform over time, potentially causing the engine to stall while driving and increasing the risk of a crash. By delaying repairs for vehicles not yet exhibiting symptoms, American Honda is placing owners like myself at unnecessary risk of experiencing a dangerous malfunction while operating our vehicles. I have contacted several Acura dealerships, all of which have confirmed they have limited or no parts available to complete this critical safety repair. This situation is unacceptable given the serious nature of the defect and the potential consequences of a fuel pump failure. I urge American Honda…”
