Car stopped working, engine replaced than broke down again told it was better but than it was exhaust. Every light was on in the car

The vehicle began experiencing a steering and suspension malfunction that made the car difficult to control, particularly at low speeds and when turning. There was increased vibration, unusual noise from the front end, and a noticeable pull to one side. These symptoms created a safety risk because loss of steering stability could have led to a crash, especially in traffic or on highways. The vehicle was taken to a Honda dealership for diagnosis. The dealership did not inform me of an active Acura safety recall related to the issue and stated that they “do not check Acura recalls.” Based on their assessment, I proceeded with repairs at my own expense. I paid approximately $435 for the replacement part purchased from an Acura dealership and about $300 in labor to an independent repair shop. After the work was completed, I later learned that the same issue was covered under an active Acura safety recall. The problem has since been confirmed by both the independent repair facility that performed the work and an Acura dealership that verified the recall applies to this vehicle. When I requested reimbursement under the recall, Acura offered approximately $312.91, which does not cover my actual repair costs. Prior to the failure, there were clear warning signs including steering vibration, noise, and handling instability that worsened over time. No dashboard warning lights appeared before the failure. The replaced component is available for inspection upon request.
