— Infiniti is recalling nearly 14,200 model year 2016-2018 Infiniti Q50 and 2017 Infiniti Q60 vehicles equipped with 2-liter engines.
The automaker says the wrong fuel pump control module software may allow gas in the main tank to be too low to keep the engine from stalling.
In December 2016, Nissan received a report from the U.S. about possible problems with a fuel pump. Nissan investigated and collected parts from the field and was able to duplicate the fuel pump problem.
Engineers improved the software logic in the fuel pump control modules, but Nissan didn't believe the problems were related to safety, apparently because the automaker didn't have enough information yet.
Infiniti met with safety regulators and issued a technical service bulletin to dealers advising them to reprogram the fuel pump control module software if a vehicle experienced certain symptoms.
Engineers determined when the amount of fuel is low in the main tank, the pressure regulator may not open and send fuel from the sub tank to the main tank. This can cause the fuel level in the main tank to be too low for the fuel pump to send fuel to the engine, which can cause the engine to stop running while driving.
The Infiniti recall should begin August 21, 2017. Infiniti dealers will need to reprogram the fuel pump control modules with the correct software.
Owners of the recalled 2016-2018 Infiniti Q50 and 2017 Infiniti Q60 vehicles may call 800-662-6200.
