Three problems related to other fuel system tank mounting have been reported for the 2006 Nissan Frontier. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2006 Nissan Frontier based on all problems reported for the 2006 Frontier.
The lock ring that holds the fuel level sensor, fuel filter, & fuel pump assembly has come loose and the assembly moved upward about ½ inch leaving a gap allowing gas to splash out of the top of the fuel tank when full of gas or going over a bump. This happened over time after the vehicle¿s fuel sensor was replaced after a recall.
Fuel gauge began to malfunction, showing and improper amount of fuel in the tank. Check engine light stays on. Fuel gauge registers incorrect level after fueling up the vehicle. I have ran out of gas on one occasion due to this. I was on the side of a busy interstate with my 6 yr old and had to cross the interstate to get assistance. This is a safety concern. Nissan tells me that my vehicle is not included in the recall and if I want to repair the vehicle it will be at my own expense. This is a widespread problem with Nissan fuel sending units on the Frontier and should be fixed in a nationwide recall, not a VIN specific recall. The product is faulty. Nissan and NHTSA should both be ashamed for not putting out a nationwide recall.
Filled my 2006 Frontier with gas one day and the "service engine" came on. The next day the gauge did not register amount of fuel in tank. The following week I refilled again and gauge did not register properly. I then drove around for an hour and it eventually registered full again. Took to local Nissan dealer and they did a scan and it revealed it had a faulty fuel level sender. The repair was completed about 2 months prior to recall being announced. I checked with the dealer and one service advisor said they would reimburse my cost, once the actual recall letters were sent out. Since then the dealer says the recall for the fuel sender does not apply to my truckand will not reimburse me. I called the 1-800 Nissan number and they say my truck is not covered . However the service bulletin say "2005-2007 Frontier - all".
