The shutter in the front of the car is defective. This part not working causes the car to overheat. There are so many issues with this exact same problem on this exact car that there is literally a back order and I cannot get the part so now I can’t use my car. My mechanic place said he’s seen 4 of these cars in the past week with the same problem and can’t get the parts because of back order. If there are this many issues that it’s causing this much of a shortage and it can cause overheating this should be a recall issue.
