2004 Nissan Frontier Fuel system Problems

“This truck has been worked on multiple times for rust, corrosion, gas tank leaks, bearings and rear differential. It continues to rust and corrode. The motor runs well but the vehicle has rusted even with excellent care. I am so disappointed. The gas tank has been fixed multiple times and continues to corrode and leak. I think that all of these issues need to be checked on. The rear differential has corroded and all of these issues are very expensive every time that it has to be fixed. I would appreciate your help with these problems.”

“The check engine light turned on in may vehicle. I had it checked and it turns out the gas tank/ hose connection to the tank is rusted causing a fume leak. This leak can be smelled inside the vehicle and is very strong outside the vehicle and is a potential fire hazard. This occurred in august 2006. I had to order a replacement tank which is on backorder until sometime in september.”

“Truck total mileage is only 55,000 as it is not used very much. 3 issues occurred approx. At 49,000miles. 1) engine started to miss. Upon checking spark plugs it was discovered that the plug cavities in the head were full of oil. The valve cover gasket seals had leaked and the oil filled spark plug holes caused it to miss. This is not covered under warranty so repairs were done at my cost. Had to replace all of the top end valve cover gasket and spark plug hole seals as well as the cam end seals. …”

After further testing they stated that the failure was due to rust on the gas tank. In which LED to a evaporation leak on the top of the gas tank. The mechanics replaced the gas tank. All the associated equipment including the gas pump. The repairs have taken care of the failure. …”

“Fuel gauge does not register properly. I have already replaced the fuel cap once and had the truck in for repairs a couple of times. The service engine soon light is on almost constantly and when the fuel gets down to 1/4-1/8 of a tank, the gauge will go up to 3/4 a tank indicating that there is more gas there than there actually is. If I do not keep track of it, I can easily run out of gas.”
