The fuel delivery system, specifically the fuel pump, has malfunctioned. This vehicle is subject to a fuel pump safety recall, which was reportedly repaired in 2022; however, the vehicle continues to experience the same failure symptoms and is available for inspection upon request. The vehicle has stalled multiple times at highway speeds, resulting in sudden loss of power while driving and creating an immediate risk of collision with surrounding traffic. My family was in the vehicle during these incidents, significantly increasing the risk of serious injury or death. The problem has been reproduced multiple times, including after the vehicle was taken to an authorized Acura dealership. During the most recent visit, diagnostic trouble codes were cleared, but the recalled fuel pump was not repaired or replaced. After being released by the dealership, the vehicle stalled again under similar driving conditions. The vehicle was inspected by the dealership, but no corrective repair was performed beyond clearing codes. The manufacturer has not yet properly remedied the recurring safety defect. Prior to stalling, the vehicle exhibited intermittent hesitation, loss of power, and engine shutdown. Warning indicators and fault codes were present at times and were cleared by the dealership without resolving the underlying issue. These symptoms have continued intermittently since the recall repair. This appears to be a failure to properly diagnose and correct a known safety defect, resulting in repeated dangerous highway stalls and placing occupants at serious risk.

On or about October 21–22, 2025, I brought my 2020 Acura TLX (brown, 99,000 miles, VIN [XXX] ) to Goodson Acura of Dallas for a recall repair related to engine concerns. The vehicle was returned to me on October 24, 2025. Shortly afterward, the car began to lag and hesitate while accelerating. On November 3, 2025, while driving to a doctor’s appointment on the Bypass Bridge in morning traffic, the vehicle suddenly stalled and lost power completely. This created a dangerous situation in active traffic. I recently underwent surgery following a serious burn injury, so limited mobility made this stall especially hazardous. After restarting the engine, multiple ADAS and system-fault warnings appeared. I contacted Goodson Acura and was advised to bring the vehicle in. Upon arrival, the service advisor confirmed the warning lights but required a $205 diagnostic fee despite the recall work. Acura Client Relations opened Case No. XXX and advised the charge should not apply if related to the recall. After waiting several hours, I was told the battery had died and that front camera/ADAS systems were returning codes. This stall occurred less than two weeks after recall repair and could easily have caused a serious crash or injury. I am requesting a full investigation into the recall repair, the stalling issue, and any related safety defects.
