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. |

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.

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?

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: |

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?

It happens to me also! It also does depend on the levelness of the ground when you are filling up your car. If it isn't flad all the way around then your car will not have all led lights lit up (ie your on a incline with the passenger side higher or the nose is higher than the tail).

It's a long shot... but perhaps try a bottle of Lucas Fuel Treatment?
I generally do not believe that these "octane boosters" and "fuel treatment" things really do much of anything. But . . . 1) My wife's DD is a 2010 Subaru Outback with about 60K miles. Last Fall, we noticed that the fuel gauge began stopping just below the "F" mark on fill-ups. Sound familiar? The gauge seemed accurate otherwise, so we decided that we'd look into getting it fixed (out of warranty) if it got any worse and would otherwise just sort of ignore it. It irritated me, but it was her DD and she didn't care as much. A month or so later, I was at a local AutoZone (like a PepBoys, etc) and they had this Lucas Fuel Treatment on sale at the checkout counter for like $3. Never used it before but thought, what the hell, right? Couldn't hurt anything. Added it and filled up the Outback. No change. Gauge still below F. Also no change in MPG, idle quality, or any of the other things it says it does, of course. But at the next fill-up, I'll be damned if that fuel gauge didn't go all the way to (and slightly past) the "F" like it used to. It's kept working normally ever since, going on 6+ months now. I'd sort of forgotten about it. This was before I bought my Z, so I didn't know anything about similar problems with Z's. Did the Lucas stuff fix it? I have no idea, but it sure seems like it might have. It was certainly worth $3, anyway. 2)So when I remembered this yesterday, I went out and bought another bottle for the Z (not on sale, $5) last night. Pulled into my garage with an already topped-up gas tank and the last LED not lit. Added the stuff, drove around a few miles. No change, not lit. This morning, to my surprise, all of the LED's are lit, as they should be. Perhaps fixed? Perhaps just coincidence? I know others have experienced intermittent behavior, so I can only assume that it won't stay fixed. But perhaps this stuff does have some sort of lubricating property that "helps" sticky sender units. No idea, I'm not a mechanic or chemical engineer. Time will tell... Perhaps worth $5 for someone else to try and see if it makes a difference on your Z. Especially for those out of warranty. It couldn't hurt, anyway. |
^^ it's been tried. Most likely a coincidence. For me, sometimes it will all light up again, sometimes it doesn't the next time I start the car. Usually though, if it all lights up, it will act normally. The fact is, you can't really trust it to be accurate since there is some sort of malfuction/defect in the actual part.

Although that has a grain of truth, it isn't true for me. All the gas stations here are relatively flat and I've tried other stations. If this was true, I would have noticed this much sooner. It's the fuel sender. It sits on top of the tank and I think it means having to drop the tank to install. It's time consuming, which is assume why some dealers hesitate to fix it.172 Fuel Tank :: Fuel & Engine Control :: Genuine Nissan Parts :: 370Z Parts (Z34) 2009-2012 :: Nissan Parts, NISMO and Nissan Accessories - Courtesyparts.com |
oh im not disagreeing with you at all. As a matter of fact, every time I fill up I top off almost a gallon and a half and the final led light is stil not lit. But I just track my mileage out of every tank to find out how much fuel I have onboard :)

I tried some Lucas Oil Fuel Treatment two tanks ago. I'm approaching 40k miles, so it was good to add it through the fuel system anyway....but it did not fix the problem. The problem is still the fuel sender and I have the original dealer I bought my car from that is going to replace mine. I still have to work out who's paying for what with Nissan though.
|
It shouldn't cost you anything from your extended warranty :)
|
I got my sender replaced without question and they seemed to know all about the problem. It was all covered under warranty, no questions asked.
|
Got mine replaced yesterday and the dealer picked up the charges in my case. Not quite sure if it's fixed; when I filled up after leaving the dealer, I still had 1 light not lighting up. Once I got to my buddies house, I restarted it and that last light was then lit up.
|
Fuel Treatments like Techron Etc.. wont do a thing because the problem is in the Elec Sending Unit itself.
if the light goes on and off, its the first syptom of the problem. |
It never fails... this thread makes me laugh every time it's brought up.
|
I had the low fuel sender unit replaced last Friday. It does appear to have fixed the problem I was getting at low fuel levels. However, I still have the problem with a full tank not lighting up all the way. I think the other sender unit will also need to be change out.

But I would counter that so long as the problem continues to arise, even in nearly-new Z's, then it's relevant and worth discussing. :twocents: Totally agree, there are far bigger problems in life than a flaky fuel gauge. And yes, there is much gnashing of teeth over a fairly trivial problem. But that is, IMHO, the gist of every automotive forum I've ever visited. :bowrofl: However, in my case the gauge actually appeared to get stuck. I drove 100+ miles with all-but-the-last-dot lit. Had it not 'magically' started working again, I could have eventually run out of gas with the gauge reading "Full-1". I was curious if anyone else has experienced this, as that is a bit more concerning than just a 'won't-hit-F' problem. I wonder if a Miata fuel gauge would solve the problem . . . :stirthepot: ;) |
normally when i top off +1 gallon it won't lite up but when i leave work at 12a.m. it is lit. I can go approx 80 miles before it extinguishes depending on how full it was when I left work and if i vary my driving mode. At 120ish is normally when it distinguishes the 2nd led light. But, being that I stuffed the hell out of my car, first light came off at 98.7 and 2nd came off at 150. I sit now at 302.4 with one lite above the half mark.

I've dealt with crazy gauges before... I used to have a Solstice GXP. It's gas gauge would stay pegged on F for the first 200 miles, then drift to three quarters by 250, then half by 275, then at any time thereafter it'd just fall to "E" with nothing in between. Crazy.:rolleyes: |
no its just that i take about 20min in my garage to fill another 2 gal. I commute 500mi a week and don't feel like gasing up in the middle. Plus im babying the throttle

I got the car back 2 weeks ago and it's working for now. Nissan was involved this time (I called them)and essentially all they did was warranty another set of sending units and test all the pin outs in the harness. I encourage you to call after the second time you have this issue because it stated in the lemon law if you go to arbitration you've had to make contact with the manufacturer in the 3 attempts to fix it. That way you have the steps in place should you decide to go that route. As you might expect I dont feel really confident it's going to stay working after 3 previous sets of senders. As much as I like the car I may consider persuing them buying it back. Also I've asked them to address the hatch not lifting past the latch when you pop it open either (stuck hatch issue). I think it may be worse on the NISMO because the size of the spoiler. That hasn't been resolved either. |
