I started having the fuel gauge issue with the last, and sometimes second last LED, not lighting up at ~18k miles using mainly 76 gas.

The last LED usually lit back up itself ~24 hours after filling up.

After using Chevron, the last LED usually lights back up ~12 hours after filling up...

...so maybe using Chevron gas and/or their fuel cleaner will help resolve the issue...

My dealer has ordered a new sender unit. However, I'm not certain I want go ahead with it. Often with dealers they can do more damage than good.

I have this issue every once in a while where the last dot in the fuel gauge doesn't light up after filling the car up. If it does happen it's only for the trip from the gas station to where I live, which is pretty much just across the street. The next time I start the car, it's always fine and the light comes on for all the dots.

There is an actual fix for as nissan has updated the sending unit also redesigned the arm with the float, just go to your service dept as there is a TSB on it also, with all the updated part numbers.

I had an issue where my car ran out of fuel but it indicated that I had 150kms to empty and 3 bars left on the guage.
At first I thought I had some catastrophic failure but when I trailered it to the dealer, they put the scanner on right away and it indicated that I was bone dry. I'm waiting for some parts to arrive that is being replaced under warranty.

Do you have the TSB number?

I just came back from the dealership and they were unable to locate a TSB although they ordered a new fuel sender.

UPDATE: Just added a bottle of Shell V-Power fuel injector cleaner as well as filled up with Chevron Supreme. Fuel gauge now reads full w/ all the LEDs lit up w/ original fuel sender!

UPDATE 7/22: Dealership replaced both fuel sender units along with O-rings. Fuel gauge had 5 dots upon entering service and now has 3 dots with the odometer remaining constant. Will post further update after fill up!

UPDATE 7/23 - All LEDs light up after filling up w/ Chevron Supreme w/ Techron!

Just had my fuel sender unit replaced under warrantee. Seems to have fixed the problem, lets see how long this lasts.

Wow. Glad I found this thread. I have run out of gas about 4 times now. My gas gauge tells me I have 3 or 4 dots left and I'll simply go around a turn and the engine just dies. The damned thing tells me I have 50 MILES left. What is that TSB?? I have to get this fixed ASAP.

That sounds like fuel starvation, how fast were you going around a turn?

Or how slow I was going around the turn..... It was slow. It VERY much so seems like the car has no idea how much fuel it has because when it gets down low, at 1-5 dots, it seems to go up and down all of the time, never knowing what amount of fuel it actually has.

Apparently we have 2 fuel sending units. Baker Nissan is installing both tomorrow on mine and recalibrating everything.

Mine did that for awhile, but stopped since. However, I notice it takes about $40 to fill up the tank from what appears to be nearly half remaining according to the gauge. With about 1/4 remaining, it took about $48 to fill it up.

Yeah calibration might be off. This is why I'm confused when I put $10-15 in the tank from completely dead empty and it lights up 4 out of 16 dots, giving me the impression its 1/4 full when its not. It costs about $70 to fill up my tank from 1 dot. I know a measly $10 won't give me 1/4 of a tank.

Mine has mysteriously been working fine again (knocking on wood as I type this).

I'm guessing fluctuations in gas additives must screw with it.
