Honestly the fuel gauge is so incorrect.

Took me 4 trips to the service department to get this fixed. It may seem ok but the fuel gauge is very inaccurate until it is fixed. I now have a problem since it is fixed filling up my car. The gas pump shuts off after half a gallon and it's a pain in the *** filling up my tank now. Thanks Nissan.

May I make a suggestion regarding the subject of the fuel gauge; because of it's potential unreliability, at one of your fill up's, record the mileage on the odometer, then when you need to fill up again, make a note of the miles you got from that tank of gas, write it down, and keep it in the glove compartment. I have not really had a problem with my fuel gauge, but it did blip a couple of times, then re-set itself and works fine 99 9/10 of the time. But because of that, and of it's reputation, I decided to get a good idea of how far a tank of gas will take me, jot it down and keep in in the glove compartment, just in case the gauge malfunctioned in the future, I'd have a idea of when I was near running out of gas.

Also, see how the low fuel warning light works for you too. I don't think the warning light is involved with the "not lighting up" problem, but why chance it. The recorded number would of course only be a close reference, and if you've been driving normally, and the fuel gauge doesn't seem accurate, then you'll be able to avoid running out of gas.

To put it simply, it may be a good idea to become aware of how many miles you'll get from a tank of gas, as an average, and become your own back up gas gauge.

~360 miles! :)

Well after owning the car for under 3 weeks and about 5 fill ups, the fuel gauge miraculously lit up all the way. go figure...

Next fillup same thing, all lights do light up....

@xdeslitx

Dammit! FML. You were right. Filled up this morning and first light didn't light up. This is soo annoying.

Travelled over 100 miles and the gauge doesn't go down at all...stuck on one dot less than full and the range keeps going higher instead of lower. Thank god I reset the trip meter when I filled up. Looks like another trip to the dealer.

Look on the bright side. Now that the weather is warming up we can go back to the Roadster top tear issues. That should help to take out minds off the gas gauge issue for a while.

They insisted it was the cluster and not the fuel sender. They replaced the cluster and it all lights up so far...it's only been a couple of hours though. We'll see....

Mine has been showing signs of issues these last few weeks/last 3-4 fills up. When I fill up, there is always 1-2 lights not lighting up to indicate a full tank. I also encountered this weekend it saying 1/2 a tank on Saturday, then 1/4 tank on Sunday...after only driving 5 miles. I topped it off at work today to double-check, and same thing. So I took it in at lunch. They didn't want to take my word for it and said I have to bring it back when fuel light is on, and they want to go fill the tank up. My gauge clearly had one light not lit up and I only drove about 10 miles from work to their dealership.

Is there any service bulletin on this?

Maybe it's a 09 issue?

My gauge started doing this same thing this weekend. 6k miles on the car, July '11 build MY2011.

Was out of town and down to about a quarter tank, filled up. Got in and immediately noticed the last dot wasn't lit. I'd seen this thread before and thought, "oh $#I*". Then I drove home, ~140 miles. The fuel gauge never changed! Just filled it up again at a local pump, and it took about 5 gallons. Really topped it off. Gauge is still at one dot below full. The gauge has seemed quite accurate over the past 6K miles.

Is it temperature related? This weekend is the first weekend where I've owned the car in actually hot weather, 95+ degrees.

Is the "stuck" gauge the same cause as the "won't-read-full" problem?

Looks like I'm in for my first Nissan 370Z service. :ugh2:

Don't let them pull your dash apart, its the sender unit. Mine was replaced and it's been good since.

I've been fighting Nissan USA and a dealer for weeks now on this, and have had nothing but resistance. The service advisor has straight up lied to the customer support rep about what she visually saw, and completely denied anything was wrong with my car. I've gone around in circles with the service advisor, the mechanic, the service manager, and the customer support lady at Nissan USA. What it has all boiled down to, is that no one is willing or wanting to make a judgement call/management decision to have my fuel sender unit replaced.

I have now taken it to the dealer across town and they are going to replace it. My current problem is whether Nissan USA is going to pick up the tab on everything or at least the labor; as I told them from the beginning that I was willing to pay for the parts but that I refused to pay for the labor charges as the problem started within my warranty. They have been pushing me further and further out of warranty by not making a decision on the matter.

I even posted photos on their Facebook page visually showing the problems that could not be ignored or denied....only to have them immediately taken down. This whole experience has left a very negative impression upon me about Nissan. I will definitely never return to the one dealer.

Two tanks and the last light still doesn't light up. I knew replacing the cluster wouldn't work, but I had a scratch on my old one anyways. The rep suspected "it's probably not the fuel sender", but it is likely the fuel sender. Nissan should really do a TSB for this. The guage kind of inaccurate until you get this fixed. I was showing 4 dots left, but was about 16 gallons when I filled up (19 gal./16 dots =1.19 gal. per dot; should have been around 14 gallons?). Basically saying that I think there's less fuel in the tank than what the guage is saying. It does seem to effect the bottom range also. I'll see if it's the same on the next fill-up. If others can confirm this?
