Fuel Gauge Issue
 

I just started up my Z and the fuel indicator shows no lights (empty tank). My distance til empty was flashing at 270 mi and my check engine light is on.

After driving 5 miles, the range dropped to 170 and the warning light is still on. I checked the gas cap. It is on tight. I tried power cycling the car a few times, no dice.

Has anyone experienced this with their Z? I did fill up with Premium Citgo gas last night. Thanks.

It sounds like the ECU isn't getting a reading from the sender unit anymore. It could be a bad connection in the wiring harness or the sender completely died (rare). I've had them get stuck before such that they show a 1/2 tank when it is actually empty but never seen one lose connection altogether.

Not to make fun of your plight but that might be your problem... "Chavez gas"...
;)

LOL. My tech at Nissan said the sender unit is faulty or a bad connection. He's leaning towards it being a bad unit. Unfortunately, since this is a new car, even though the active code thru diagnostic is a common problem with other models they must spend hrs troubleshooting it for Nissan to warranty it. Also if it does require a new unit, Nissan most likely has not started making them yet as was the case with my seat heater that never worked from delivery. I am currently waiting on Nissan to make a spare seat to replace it.

This is starting to sound a lot like the reliability issues that caused me to get rid of my 350z.....

Nissan USA confirmed today that my car is the first 370 to have this problem reported. I am sure it won't be the last. Whoever it happens to next can thank me for letting Nissan spend many days working on it so it can be troubleshooted quickly in the future! haha

my fuel light issue is different, but here goes the last few fill ups the first led (when full first led) won't light up and some times the 2nd one either not a huge deal just b@#$%ing i guess but anyone else have this ??

I think that digital gas gauge looks out of place, they should have put a normal gas gauge. The Mini gas gauge is similar, looks like a flower with each light a flower petal... Really gay not very accurate at all.

i got the exact same problem, it irritates me, cuz i think the tank isn't full, then after a min or two of driving, all the lights light up and shows a full gauge.

nothing wrong with mine, but I tell ya, 3rd dot doesnt last more than 5 miles before it drops down to two, pisses me off.

The low gas light does come on very early. It is very misleading as you can still drive fort a while although I don't recommend it. As far as the first LED not lighting up until you start driving, that could possibly be the fuel injectors?? Not sure, but thats the first thing that came to mind?

My car is still in the shop, hope to hear something today on when I can return the Rogue and get my Z back!

I don't recommend hard driving below a 1/4 tank, or you may find yourself stranded.

Maybe we can hope for a new gas tank and fuel pickup sender and line...

I've run my gas down super-low a few times. I have backup transportation, and these are times when I know all my driving in this car will be within a few miles radius of my house, with lots of gas stations around. What I've noticed is that at the bottom end of the gauge it's either very inaccurate or very pessimistic, one of the two. Usually it becomes pessimistic after having been shut off. Like, I'll shut it off still showing 30 miles range, and then when I start the car up a couple of hours later, after a minute of warmup it's showing the "--- Miles", whereas if I had kept driving it would have kept counting down to at least 17-ish before it does that.

I know they're trying to prevent out of gas situations for idiots, but still, I'd much rather have an accurate fuel gauge.

Or maybe they know that the car is unreliable on low fuel? :ugh2:

I too have this minor irritation.

Well that too, but it's not like I'm slinging it around hard corners when it's that low :)

Clearly, someone needs to develop an aftermarket pressurized fuel cell so we can all drive upside-down and not worry (and a dry-sump oil system too). :p

no matter what i fill the tank and the first led won't come on period. not after driving awhile, not after turning off nothing ???

Yeah, I'm having a similar issue, but for me, it's my last led. It just stopped lighting up around 3 fill-ups ago. Somewhat annoying, but I guess I'll just live it it for now.

My z just started to not light up the last light as well. I was hoping it would go away with the next fill but it seems not =(

Same here...last LED and sometimes the second one too.

That happened to me back in October. The first light would not light up after a full fill. Lasted two tanks and hasn't recurred. I guess it healed itself.:bowrofl:

It will stop again, just like mine and all the others.

its under warrenty take it to the dealership

This is more of a common problem then Nissan is willing to admit. I had my fuel sending unit fail on my 350z (79,000 mi). It seemed to be a common issue among 350z owners. It appears they still have not corrected this issue on the 370. I hope my 370z is still under warranty if the sending unit fails on this car.

I have had the same issue with the LED's. Actually just traded in my 09 coupe for a 10 roadster and the gauge is fine so far...

I'm not that concerned about it as long as it only effects the LEDs at the full end. However, I will mention it to the dealer at my next service and have it fixed before my warrantee runs out. Don't want them touching anything unless it's absolutely necessary.

I have the exact problem...... Sometimes if I'm lucky, you turn the car off and then back on the first led will light and stay on. Other times (most of the time) the first led stays off on mine too.

is there a recall on this sender thing?

Nissan makes plenty of fuel senders. Whoever is telling you there is no replacement for your seat heater is yanking your chain. This isn't some limited 30 car run of Bugatti Veyron SSs.

so just got my car back from the stealership and they change the whole guage cluster and guess wat the last led still dont work so they want me to bring it back in. i told them about how ppl say its the fuel sender but they wanted to change the whole cluster first. well will see wat they say when i bring it in today again. i dont mind its all under warrenty but only thing sux is i gotta get a rental car and pay for insurance so i lose 9 dollars a day

What a complete waste of time trying to get that "really important" first LED to light. Wow!

I thought when the problem was a warranty issue (their fault), they supplied the rental. At least, it worked that way when I had my Acura RSX.

Check your auto policy. Rental car coverage or temporary use vehicles are often covered under your standard auto policy at no charge. You shouldn't have to pay for their insurance.

Just let it be...
 

It basically looks like the fuel sensor does a bad job of "guestimating" how we drive. My last fuel L.E.D. dot (going from left to right) hasn't turned on for at least the last 6 months and then all of a sudden, it turns on tonight after refueling. I've got almost 30K on the odometer. Usually when I fill up, it says that I have about 385 miles of driving left, but for some reason when I filled up tonight, it told me that I have 426 miles left...probably because I haven't been racing anyone recently ;)

so when I took it backsecond time to get it fix all led light came on so I left the dealship. I think it depends on the gas we use, are car is picky. Ive been using shell and the last led would come on but if I throw insomething different it gets all screwed up. Yea I dont trust the mileage reading anymore ive had mine say 4xx mileage left and I have had it say 300 on full tank. Do want to take it backin and get thesender change but my warranty I think is over. They need to put a recall on this so I can get it change for free

I think you guys need to understand that estimating how much gas is in the tank and calculating distance to empty is an inexact science. Deal with it.

With the amount of money we spent on our car brand new, it shouldnt come with problems. This lil stuff should of been fix before release the car. Fuel sender problems should not be an issue they been making cars for yrs they should have that atleast perfect.

There are ppl running out of gas cause the sender isnt reading right and u want them to deal with it?

The sender is reading fine. They didn't run out of gas, they had fuel starvation in a corner with 1/4 tank. Get the car back on level ground and it will start right back up. Whether or not the last LED on the right lights up isn't going to have any bearing on them running out of gas.

After the last track day my fuel gauge is stuck at 1/2 tank, I think I bent the float arm with high G's. Did that on my G35 a few years ago as well.

Ouch my expedition is like that its stuck at 1/4 when its full tank. Dont even wanna try and fix it since no warranty on it
