I've owned my discovery for less than a year and have already had this issue twice. First incident I was going to get gas as my low fuel light was on. While driving, the car shut down with a gearbox fault message. Dealer said that even though there was still 19 miles to empty, the low fuel caused the fuel pump to fail. Fortunately, they replaced it at no cost to us. Last week, the same thing happened again. 30 miles to empty and it just shut down with the same fault. I put fuel in it and the check engine light eventually went off and it seems to be running fine. Had anyone else experienced this? I've never owned a car where the fuel pump needed to be replaced if the fuel level got too low. I won't own this one for long if it's a common occurrence with the brand. Any feedback here would help. Thanks!

Low fuel levels will cause the pump to run hot.
Your vehicle has a "saddle type" fuel tank. So, fuel is siphoned out from the left side and dumped into the right side.
The fuel pump is on the right side.
When the fuel level is low, the fuel sloshing around can cause the pump to cavitate.


Best thing to do is not run it so low on fuel.

Just had this happen on my 2016 LR4. I’ve owned a lot of vehicles and have never had a check engine light come on when the fuel gets below the 1/4 mark. Checks the codes and was real worried to see it was fuel pressure related with only 60k miles. Almost had the dealership dig into it but fueled up and the light went away when I was driving to the dealership for an oil change. Will be fueling before the 1/4 mark from now on. Good luck!

I never let it get below 1/4 of a tank anymore, but this seems like a ridiculous situation. If the thing won't run with less than a 1/4 of a tank of gas that seems to me like a manufacturing flaw. Also, the last time (now 3rd) that it happened, it was over a1/4 of a tank. I wonder if this will continue to get progressively worse Hate paying that much for a vehicle that I can't trust not to leave my girls stranded along the highway.... again!!

The fuel level sensors can be causing this too.
Showing the incorrect fuel level.
