Fuel nozzels will not shut off when I am filling my tank. This happens at all stations. I have the nozzel full into the spout
Have you been in the habit of topping off the tank after the nozzle shuts off the first time. If so that is likely the reason and if you look around I would not be surprised if you find a sticker on the car or instructions in the owner’s manual to NOT top off the tank, it can damage the vapor recovery system and in turn this problem.
You may need to have it corrected by your mechanic.
