The contact's girlfriend owns a 2004 Nissan 350Z. The contact stated that upon refueling the gas tank, a large amount of gasoline began to leak out from the gas tank and underneath the vehicle. The contact also stated that upon entering the vehicle, a strong fuel odor began to emit from the vehicle. Due to the failure, the contact had the vehicle towed to his home. The contact called the dealer and they informed him that there were no recalls on the vehicle. Upon investigation, the contact discovered NHTSA Campaign Number: 05V555000 (Fuel System, Gasoline) which he linked to the failure. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 115,000.
The contact owns a 2004 Nissan 350Z. The contact stated while refueling the vehicle, after stepping away from the vehicle, the contact was alerted by his passenger that there was a fuel leak underneath the vehicle. The contact stated that the passenger was alerted by the odor of gasoline. The vehicle was taken to an independent mechanic where it was diagnosed that the fuel pump filler neck needed to be replaced. The vehicle was not repaired. The local dealer was not contacted. The manufacturer was not made aware of the failure. The failure mileage was approximately 131,000.
During normal operation of a 2004 Nissan 350z the fuel tank was puncher and approximately 15 gallons of gasoline spilled onto the road. I was traveling at aprox. 30 MPH on surface streets when I heard a pop & continued driving for about 2 miles. When I got out of the car I discover gas was heavily pouring out. The fire department and police secured and cleaned the area then towed the car. According to the dealership a small piece of road debris, that they believe to be metal, punched the fuel tank. The dealership has also confirmed that no safe guards are in place and no protective measures have been taken to prevent this type of incident from occurring in the location where the hole exists. …
Thousand of reported cases of not being able to fuel up the Nissan 350z. The problem source is the filler neck shutter valve. Nissan is aware of the issue for years and have been making customer foot the $400-$500 bill instead of taking action on the faulty part. The faulty shutter valve causes fuel to spew out while filling the tank covering the car and operator in fuel. The risky part is people are changing the way they fill to try to bypass the action of the shutter valve but also works against the safety features of the gasoline nozzle causing it to not shut off when fuel reaches max. I personally cant only get 7 gallons in my car before it sprays out which is very annoying since I have to fight to add 7 gallons of fuel everyother day. I fought with this issue in my 2003 350z and my 04. It is extremely common and should have been recalled years ago.
Nissan 350z have a fuel gauge problem in which many are experiencing. When the gauge reaches below 1/4 tank full it will show as empty. Once the car is turned off the gauge will show as empty even when fuel is in it. The in accuracy of the gauge leads to people over filling their tanks with gas. It has lead to cars running out of fuel on highways. And it has caused dealerships to not know how to fix the issue or over charge on trouble shooting issue they have no idea how to handle. This issue deals with fuel and it is unsafe for we cannot determine how much fuel we have which can lead to over pumping and/or running out of fuel on highways.
The fuel gauge doesn't accurately reflect the amount of gasoline in the fuel tank. Examples include when the fuel tank is filled to the point of overflowing, the fuel gauge randomly reports, 3/4, 1/2 1/4 and sometimes empty. The fuel gauge randomly reports different fuel levels each time the ignition is turned on. Further research of the described matter on various online 350z forums indicate the same problem exists for many other 350z owners, which indicates a product defect. The forum that follows is one of many examples: http://my350z.com/forum/maintenance-and-repair/501507-fix-for-gas-gauge-fluctuations-hard-to-fill.html.
I have a 2004 Nissan 350z touring edition, I been having a problem with the gas gauge from what I have noticed is when the gauge is below the half it starts fluctuating from e to about a 1/4 or even to 1/2 tank. When I turn the car on and off it starts off at empty and will slowly make it way up to what ever it wants this problem has been going on with these car for a number of years but nothing has been done from Nissan. So I never really know how much gas I really have I thinks a very dangerous problem to have because what about if you need to pull out into traffic and your car cut's off because it has no gas. Game over right!!!
Tl* the contact inquired about a 2004 Nissan 350z. The contact stated that after refueling, the fuel gauge displayed a reading of being of the way full.

The vehicle was taken to an independent mechanic where the contact was informed that the failure was due to the fuel level sensor. The vehicle was not repaired and the manufacturer was not made aware of the failure. The failure mileage was approximately 75,000. Updated 08/31/2011
The fuel gauge en the speedoometer does not tell the correct amount of gas in the car. It says there is fuel when the care is actually empty causing me to get out of gas for several times. I took it to the dealership and they told me the only way to repare it is to change the whole speedometer, and that the cost of it is almost a $1,000.00. This is a lot of trouble for me because I have to fill up the car every 2 to 3 days so the car doesn,t leave me with out fuel.
I have same problem as reported in my carstats.com custom report #10073235, I.e., on occasion unable to pump gas into gas tank. Tried different pumps and different gas stations. Serious problem when traveling and can not get gas in tank. In addition, fuel tank when filled does not show full. On 2/18/05 dealer said they could not "find concerns at this time--customer to monitor." this has been happening aperiodically in terms of not getting gas into tank.
