Today I start up my 2014 JKU Sport with 1200 miles on it and the fuel gauge says it is completely empty. This was hard to believe because I just filled it up 2 days ago. So i turn off the Jeep and turn it back on again and it still says empty. Now I start wondering if the tank is leaking or something. After checking to see that everything is ok, I turn my jeep back on and it registers 3/4 of a tank. Has anyone had this issue or know anything of it?
