So I have this problem with my 2103 LR4. From time to time my gas tank will not fill properly, and it will cut off as if full when it is barely filled. At the same time, the check engine light goes on and off from time to time, and sometimes the gas cap is loose light comes on too. Whenever it does I check the cap and it is perfectly attached and tight. sometimes the gas gauge jumps around at the same time, sometimes it doesn't. Then these issues go away for a while. And then return in some odd combination or sequence, but always with the gas tank not filling correctly. So what is this? I've tried searching for this issue and can't find anything.
