The module around pump is designed to let car run with as little as two cups of fuel left in tank to prevent pump running dry at least on earlier models, I assume same on all vehicles now since they went to modules to stop pump warranty issues from tanks running low and starving pump. Pump can die with as little as 30-60 seconds of dry running and why all owner manuals now say to never let car run out of gas.

There is a small one way valve that allows fuel to come in module on demand but not seep back out, if it has trash stuck in it or not sealing fully then could easily be the issue there.

One gallon was not enough on mine to prime pump once it ran dry on a slight slope at indicated 1/8 tank, when doing pump work I always use a minimum of 3 gallons back in before i turn pump back on. It's stupid to burn up a brand new pump, I saw it plenty of times though at the parts store. When questioned hard most customers with the issue usually admitted they only used like 1/2 gallon thinking that would be enough. Not nearly, you want to really flood that thing.

The dealer was very helpful and towed the car back to diagnose the issue. 3 days later the dealer calls us up and says it was just low fuel and a sloped driveway! The driveway is definitely a bit sloped (just measured 8.5 exactly) but nothing that extreme. Coming from a hilly city like Vancouver this is a pretty bad design flaw, wouldn't want my car cutting power out going up a hill! There was no low fuel light or chime or anything yet (I hadn't owned the car long enough to know if it even has one... ).

After doing a lot of research on the car's other issues, I have a feeling this bad tank design may be related to other issues people have had sputtering on slopes and sputtering doing gentle acceleration around town. The fuels probably sloshing to the back of the tank causing stumbles or flat out causing the car die if on a hill.

I hope this helps someone! In a way we're glad it happened, as this would have been a nuisance down the road for us!

Dealer was very helpful, they took the car back no problem.
Hi Tobyz28,

Do you have the car with you now or is it at the dealership? Please send me a private message with your VIN, odometer reading, phone number, full name, and servicing dealer; I'll look into this for you.
