The National Highway Traffic Safety Administration began an investigation of the 2003 and 2004 Infiniti M45 late last year over inaccurate fuel gauge readings, and now that probe has resulted in an official recall. The culprit has been identified as a faulty circuit board that causes the gauge to register more fuel in the tank than the car actually has.

According to NHTSA, Infiniti will begin notifying owners in mid-April, at which time they can take their sport sedans to the dealer to be replaced free of charge. Follow the jump for the official word from NHTSA with more details.
