Which G37 is which

Coupes ran 2008-2013, sedans and convertibles 2009-2013. The 2008 coupe is the only G37 that EPA lists with a 5-speed automatic; the 7-speed arrived for 2009 along with the AWD G37x coupe. A 6-speed manual was offered on S Sport 6MT models throughout.

For 2014 the coupe and convertible were renamed Q60, and the sedan returned as the Q40 for 2015, so a 2014-2015 Q60 or a 2015 Q40 is mechanically the same family of car with the same 3.7L V6.[1][6][14][16][3]

G37 recalls to check before you buy

NHTSA's recall records list two G37 campaigns. Have the seller or an Infiniti dealer confirm both are closed for the VIN you are looking at.

  • 08V521000 (Oct 2008): 2008 G37 Coupe (with 2007-2008 G35 Sedan and other Nissan models). The occupant classification sensor in the passenger seat could interrupt its signal to the airbag control unit and suppress the passenger airbag. Dealers test the system and replace the seat cushion if needed.
  • 11V538000 (Nov 2011): certain 2011-2012 G37 Coupes built July 2 to Aug 29, 2011. The power window switch's auto-reverse threshold was set higher than specification, raising pinch risk. Dealers replace the switch.
  • [17][18]

What to check on a used G37

Confirm the exact model with the window sticker or VIN decode: G37x means AWD, and S Sport 6MT means the manual with sport brakes, sport suspension and a viscous limited-slip differential on sedans. Check that the recall work above is on record, and get a pre-purchase inspection, since even the youngest G37 is now more than a decade old.[7]

Infiniti G37 problems and recalls

The G37 has two recalls in the NHTSA dataset that name it. Recall 08V521 tests and, if needed, replaces the passenger seat occupant sensor on 2008 G37 Coupes because it could switch the passenger air bag off. Recall 11V538 replaces power window switches on some 2011–2012 G37 Coupes whose auto-reverse needs too much force to trigger.
