Nissan Agrees to Fix Quest Gas Gauges Following Investigation

Roughly a year after an investigation was opened into inaccurate fuel gauges, Nissan has agreed conduct a “service campaign” for the 2007-2009 Quest.

How does a service campaign differ from a recall? A recall is a fix related to a safety issue and some are federally mandated. A service campaign is issued by the automaker to upgrade or repair your vehicle for something that isn’t necessarily safety-related. Now, this is where the line gets grayed because I would categorize running out of fuel on a crowded highway as a serious safety defect, but Nissan doesn’t. You say tomato, I say car crash.

In any event, the issue appears electrical in nature:

Nissan says the gas gauge can give inaccurate levels because of problems with resistors in a circuit in the sender unit. The automaker found one of two resistors could open and cause false gas gauge readings when the tank goes below one quarter of a tank. Gas would be used out of the tank all while the gas gauge said a quarter of a tank was available.

To fix it, Nissan dealers will install an external amplifier box with jumper harnesses to bypass the resistor’s electrical circuit.
