Other Fuel System Tank Mounting Problems of Infiniti FX35

My 2012 Infiniti fx-35 fuel gauge stopped registering fuel levels about three weeks ago, and the warranty expired three months ago. I noticed the issue when starting the car in my garage. I contacted the Infiniti dealer, and they mentioned that I would be responsible for the repair which would not be covered under warranty. The problem actually involves the fuel sending units, Nissan pn 25060-1cb0c and 25060-1cb1c, which retail at approximately $130. 00 each. Parts and labor are in excess of $600. 00. I looked up some past NHTSA bulletins involving Nissan fuel sending units and found the following NHTSA bulletins: 10v-074, 10v-075. All Nissan vehicles, including Infiniti, utilize the same design for their fuel sending units, which involve a floating arm with contacts that sweep across a contact array to register e-f. I contacted Infiniti customer care who informed me that they could not offer any compensation toward fixing the problem. I then located a youtube video that showed the problem was with the contact array that becomes oxidized after a certain amount of time. I then fixed my problem by removing both fuel sending units from the gas tank, and cleaning the contact array on each using a cotton swab. This is clearly a faulty design, and Nissan should issue a recall for all makes/models.

My fuel indicator did not register a full tank and would fluctuate randomly while driving or stationary, so I never really knew how much gas I had. I couldn't us the the fuel economy/miles to empty calculator because it seemed to be basing miles to empty on what it was registering, not the amount of fuel actually present. It all of the sudden fixed itself, and now the same problem has returned again. It seems to be a fairly common problem from what I've read - why no recall????.

I do see multiple other owners with the same issues. Please find my issues here. . . . . . . Issue 1: the gas gauge improperly represents the fuel level in the tank and the following issues are constantly present: 1) a full tank is never shown via the gauge 2) the gas gauge sporadically jumps around regardless of the amount of gas in the tank 3) the "empty" light comes on when there is as much as 1/2 tank of gas. This is very dangerous for me as this is my family car and I have a 2 year old son in my vehicle a lot and what if my car would stall out on the highway?? it is a good thing that I am able to keep calculations on the amount of miles per gallon my car usually gets. I was going 30 mph and turned from a light and didn't realize my gas was as low as it was and my car stalled out, luckily I was able to get over to the side of the road. Issue:2 the locks fail to react to the lock unlock function and the beep sound doesn't go off.

After turning the ignition switch the engine will just rev without full ignition of the engine. It seems as if gas is not being provided by the fuel system during the ignition sequence. The fuel pressure of the tank seems to be the malfunctioning issue.
