About 8-9 weeks ago we had an accident with our2017 Buick envision, we hit some ice went in ditch and caused extensive damage. During the course of repair there are two parts that we Are unable to get, two molded baffles that fit in the front of the vehicle, one is an underbody shield (84197387) the other one is an upper air I let (22900934) the latest info is there are none in United States, but they are on order and the body shop is to modify the damage one put them on , we will get car back then when new parts come in they will replace. This has gone way to long and I feel that the support and help I M getting from Buick is not there, there are Buick envisions at various dealers and I do not understand why they cannot swap parts
