There is an open recall which has not been addressed in a timely manner. The below has been open since oct 26, 2023. I have been advised that I would be notified when a remedy was available but it's been ten months with no solution. My front bumper detached while I was on the interstate causing damage to the front end of my vehicle. The subject vehicles are equipped with a resin front lower bumper cover assembly, connected with mounting tabs. If there is minor impact to the lower front bumper cover assembly that causes the mounting tabs to detach from the vehicle during normal operation, one or more parts of this assembly could detach, which could become a road hazard, increasing the risk of a crash or injury for other road users.
