The problem at hand is that the Fuel Gauge in the car does not give accurate readings as to how much fuel is in the tank. In most instances it shows that you have half a tank when in reality it is empty.

If you would post your Year, Make, Mileage(when problem occured) and dealership of repair(if you had repairs done).

I will start this post off. Hopefully this helps someone with this problem.

First they replaced the Fuel sending unit. I hadn't let my tank go down for awhile, so I never really knew if it was fixed. Finally noticed around 32K and took it back. It was out of warranty of course by that time, but they replaced it for free anyway. The whole cluster had to be replaced. I think Infiniti is aware of the issue and that's why they have been replacing the parts even out of warranty.

Had the issue for over a year now. I'm not one to usually let any of my cars fall below a quarter tank, but this particular car, I fill up every 200 miles to be safe. Yes, it's annoying. Yes, I should take it in. The problem is my 1 and only experience with my closest Infiniti dealership in Barrington, IL was not a good one, so I live with it. Personally, it doesn't bother me much as I don't even pay attention to the guage anymore, only my miles, but I know that's no excuse for a car that started out over $50k 5 years ago. (Maybe I should replace my gas guage with something more useable like a radar detector display or an MP3 display).

Hope this helps with some ammo. I know I could have used some ammo the day I tried to get my cat converters taken care of almost 20,000 miles ago.

Fuel gauge would show full when actually near empty. I had the extended warranty so I paid the $100 deductible and they replaced the whole cluster. No more problems. Now I'm having problems with my Audio control module

From my experience and from what I have read from others, this is the Cluster itself and not the sending unit.

I know there are alot more of you out there. Post it up!!!

Just purchased the car a few weeks ago. 93k miles.

Rolled into the garage last night with the low fuel warning on. Came on as I entered the driveway.
Got in the car to go to work this morning and it showed 1/4 tank.

10 miles down the freeway - putt putt putt.... ooooh CRAP!!!

Fortunately, it was prior to 6am, so little or no traffic, and these cars coast really well. Made it off the freeway and coasted into a gas station.

No more fillups beyond 300 miles on odo.

Haven't even contacted the dealer about the problem - likely no assistance would be provided at this late date.

It's obviously a very common problem. My dealer fixed it out of warrenty. You could aslo call Infiniti corporate.

I just started having this problem last week. Ill give my infiniti dealer a call one of these days to see what could be done since im not covered under warranty anymore. I'll probably try calling infiniti corporate too.

I took my vehicle to the dealership for diagnosis of the faulty fuel gauge problem. Same day contacted infiniti consumer affairs informing them this appears to be a common problem etc. ConsAffair advised they would look into it. The dealership confirmed a faulty gauge and quoted $650+ tax to fix. (Warranty exp in Nov 07). Two days later, dealership called and said they would repair at reduced price per ConsAffair. Got my vehicle back today and was only charged for the oil change!

I would advise anyone experiencing this problem to call infiniti Consumer Affairs - several times if needed.

Good Stuff™!! I am glad it worked out well for you.

Excellent advice for sure.

Fun: 96 Deep Evergreen Maxima, 5spd swap, Quaife LSD, cammed-VQ35, black leather interior swap, lots of other stuff

Cruiser: 04 Obsidian Black M45, black leather interior, 35% tint up front, 5% rear

I then called my semi local infinity dealer, they sort of said they had heard of the problem but that the repair wouldn't be covered under warranty. I will never go there now! (oh yeah, only reason I needed them was for free stuff anyway ).

Welcome to NICO.

I would call Infiniti Corporate and discuss this, without getting angry, but without allowing to accept NO for an answer.

Too many people seem to be experiencing this issue, and it may well be endemic enough to warrant them fixing it ... even though your car is not covered anymore.

Good luck with that effort, and please let us know if you are successful.

They need to realize the severity of this issue. It takes a number of deaths, yes deaths for a car manufacturer to claim something as a recall issue. That in my opinion is absurd.

Mentioning a lawyer would kill your claim right then and there. As soon as legal action is even hinted, you'll be referred to the legal department and you won't get your car fixed.

Not necessarily. If you cannot get a satisfactory disposition of your product issue, then its time to let the CS contact know its up to Infiniti to avoid a legal remedy. Be clear, no filing is anticipated but legal consultation is a given. Small claims are published in the local newspaper. Infiniti wants no part of this avoidable PR hit.

I think you are correct. I had my tach replaced and then my gas guage read higher than it did before. I think that's all one unit.

Does this mean the miles to empty calculation is also wrong?

Ran out of gas on busy street, gas gauge showed half full. I never really let gas gauge run down. Have always filled up at half way mark. First time (without knowing) that tank ran empty. Have it scheduled for service this upcoming week. Will let you guys know outcome, but glad I have this thread to bring to the dealership.

Gauge Cluster needs to be replaced; $650 job. Gee, who would have thought it could be that problem? Unbelieveable that Infiniti insists this is not a manufacturer problem. I have owned about 16 cars over the past 40 years and not one of them has ever had a fuel guage problem. Let alone replacing the entire cluster of the dash board to fix one. I have a call into Consumer Affairs. They said they would look into this problem, but have not really seen it "as an issue". Will keep you posted on result.

Good Stuff™!!

It stayed on for a week or two, then went off and has come back a few times since. I had a friend run the code for me, DTC P0462 Fuel Level Sensor and I am ordering the parts from Pinnacle Infiniti including a new fuel filter to be installed with the new level sensor. I have already contacted Infiniti and opened a file claim mentioning the fuel gauge and the likely replacement of the guage cluster, like many others here have had to have performed.

I'll let you all know how the sensor and fuel filter install goes and it is clears the code after the new test. Emissions control testing is required here in PA FYI.

I noticed my tank is lasting much longer than usual..then remembered this thread and stopped to fill up.

Gauge was reading just under 1/2, but took 17.5 gallons, hmmm..
just to be sure, these cars don't have 34 gallon tanks, right?

Another thing to add to the 'to-do' list, sheesh.. (more accurately 'to-do when I have some cash to spare' list)

So, I get in the car this evening and fire it up and drive off. The gauge reads a little over 1/2, and the trip odo is at 145. I go into the store and pick up some things, come back out and drive off and notice I now have 3/4 of a tank! Some nice stranger apparently put gas in my car while I was in the grocery store. Or maybe not? When I parked it in the garage, I stopped, then started it again and the gauge dropped down to just over 1/2 again.

Is there a THREAD like this one that lists ALL the "Common" problems the03/04 M45's experience? It would be nice to know what else I can expect, especially since I only have 34K on this beast.
