Fuel pump precautions

I recently ran my fuel level low on my '16 Sorento. I was on the home and low price Costco gas is .8 miles from my front door. When I filled up the "Range" display said 1 Mile remaining. I pushed it one other time.

I have a friend that used to own a repair shop and he said if it is an electric fuel pump and located in the tank it could overheat and destroy the pump causing expensive repair, not to mention getting stranded.

Does anyone here have the knowledge of the Kia system to asses this possible risk? Any fuel pump failures?

In the majority of cases where fuel level is a contributing factor for an in-tank pump failure, talking to the customer uncovers that the tank is run low on fuel a great deal of the time.
Don't make a habit of the kind of event you describe above, and you shouldn't have this kind of problem.

Also, there is a gallon or two in the tank when the Miles to Empty says zero.

Not sure if it is the same for 2019, but prior in this generation it was 18.75 gal capacity, and if the range on mine goes to -0- I can get about 17.65 gallons into it at the pump, leaving a 1.1 gallon 'reserve'.

It must be a bit more than that though, yesterday I filled up 71.9L / 18.9 gal, the range was already showing ---, but maybe only for 1-2k.

Maybe they're selling "imperial liters" up there in Calgary

What does your manual say with regard to capacity on your 2017? Same 71L as for 2016?

I don't know of any modern cars that don't put the pump in the tank and yes, it relies upon the gasoline to cool the pump. Our household rule of thumb is never less than 1/4 tank (which is really more like 3/8 of tank with the built in fudge factor).

My daughter burnt out the fuel pump on a 2000 Mustang by running it dry. More than once.

I've had two in-tank fuel pumps fail. Never ran the gas low.

The '95 Toyota Landcruiser would get slower and slower on the highway, adding some gas would cool it enough to get going for a while longer. That was key to diagnosing the problem. The fuel is pumped to the engine and what is not used makes its way back to the tank on a return pipe. This brings engine heat back to the tank.

The '86 Pontiac was out of service due to fuel pump failure for almost two weeks. The third one the shop installed worked OK, the first two replacements were out-of-the-box bad and that was not known until everything was back together.

Thank goodness No Turbo /// 2019 Sorento SX L V6 (FWD)

I had 1 mile of range left but I had 1.41 gallons remaining in the tank according to my calculations. And no, I'm not going to make a habit of running it to Zero Range. However, IMO, it is a good practice to know your vehicle and it's limitations and capabilities.
