Empty fuel tank with 1/4 on the gauge?

Has anyone else heard of any disparity between actual fuel tank level and what is shown on the gauge? Our 2015 limited was towed off the freeway with just over 1/4 tank showing on the gauge and diagnostic code for low / no fuel pressure - tank is dry as a bone. Reluctant dealership is replacing modules and looking into a calibration procedure. My bigger concern is the fuel pumps running dry while trying to get it out of the traffic lanes. 854 miles on the odometer, just working our way through the second tank of fuel . . .

Re: Empty fuel tank with 1/4 on the gauge?

Same thing happened to me

Mine is a diesel but if you put a few gallons of fuel in the tank and everything works then most likely one of two fuel pumps within the fuel tanks went bad
I reported this earlier in the diesel 3.0 thread, in August
Since my fuel pumps within the tanks were replaced, no problems
These are different fuel pumps then the high pressure ones that feed the diesel

There was a flash for this:

A couple of people were saying that they car would just die when they had 1/4 tank or less of fuel even though the tank wasn't actually empty.

Re: Empty fuel tank with 1/4 on the gauge?

Well it's back on the road with the following repairs:
-Dealer added 5 gallons of fuel and engine started and ran fine.
-After dropping the fuel tank, they reported the left side of the tank was empty and the right side has 1/4 tank. They replaced the LEFT fuel pump and the RIGHT sending module.

As a retest I ran their 5 gallons down under 1/8 of a tank until the low fuel indicator came on. At this point I had driven it 170 miles with 60 miles still showing on the range and I added just over 21 gallons until the pump auto shut-off. At this point the fuel economy is displayed at 30.0 mpg, and I do not know what the capacity of the tank is so I am not sure if there was really 2 gallons left.

Still some learning to do before I completely trust it, but at least it is running.

Wow! That's bad. This may be something of a Chrysler tradition though. I had a 1972 Dart that would sit on 1/4 tank forever and then drop to empty at the same time that the engine stopped. Took a couple of times to figure that one out.

Since August when mine went out I have not had any problems and you are the second one to report this on JG. (At least that I saw)
Also, did not find any other mention of this problem on the national transportation safety board (NSTB) website so hopefully it is more of "bad luck" than a chronic problem. Did you look at or report the problem to NTSB?
