2012 Infiniti G37
Vehicle Specs & Maintenance Data
The 2012 Infiniti G37 maintenance specs on this page cover the key fluids, torque values, and wear items you need for routine service. Use these numbers as a quick reference when performing oil changes, tire rotations, brake jobs, and other scheduled maintenance on your Infiniti G37.
For oil changes, the 2012 Infiniti G37 takes 5W-30 Full Synthetic motor oil with a capacity of 5.1 quarts. Brake fluid type is DOT 3, the recommended coolant is Blue Long Life Coolant (OAT), and transmission fluid is Nissan Matic S. Always use the manufacturer-recommended fluids to maintain warranty coverage and engine longevity.
When mounting wheels on the Infiniti G37, torque the lug nuts to 80 ft-lbs using a calibrated torque wrench. Over- or under-torquing can lead to warped brake rotors or loose wheels. Re-torque after 50 to 100 miles on newly installed wheels.

Common problems reported by 2012 Infiniti G37 owners, with recommended fixes and estimated repair costs.
Oil Gallery Gasket Leak
The VQ37VHR engine can develop leaks at the upper oil pan gallery gaskets, causing oil to seep from the junction between the upper and lower oil pans. Oil drips onto the exhaust or subframe, producing a burning oil smell. The leak can be significant enough to cause low oil levels between changes if not addressed.
Replace the oil gallery gaskets, which requires removing the upper oil pan. This is a moderately involved repair as the subframe must be lowered or the engine raised for access. Use genuine Nissan/Infiniti gaskets and follow proper torque sequences. TSB NTB06-042A applies to this engine family.
Est. Cost: $500 - $1,200Steering Column Clunk and Play
The steering column can develop a noticeable clunk or play, felt as looseness in the steering wheel. The issue is caused by wear in the steering column intermediate shaft universal joint. It is most noticeable when turning the wheel at low speeds or when going over bumps. It gives the impression of a worn steering system even though alignment and tie rods may be fine.
Replace the steering column intermediate shaft. The lower U-joint is typically the source of the clunk. Some owners have had success lubricating the U-joint as a temporary fix, but replacement is the permanent solution. Infiniti has not issued a specific TSB for this issue on the G37.
Est. Cost: $300 - $700Electrical Gremlins and Battery Drain
The G37 can suffer from parasitic battery drain and intermittent electrical faults. Common symptoms include a dead battery after sitting for a few days, trunk latch not releasing, Intelligent Key system not recognizing the fob, and erratic behavior of the automatic headlights or interior lights.
Perform a parasitic draw test to identify the draining circuit. Common culprits include the trunk latch actuator staying powered, the Bluetooth module not entering sleep mode, and aftermarket accessories wired incorrectly. Replace the battery if it has been deeply discharged multiple times. Check for TSB ITB12-019 related to BCM issues.
Est. Cost: $100 - $800Catalytic Converter Premature Failure
The catalytic converters can fail prematurely, particularly the front pre-catalytic converters integrated into the exhaust manifolds. Check engine light codes P0420 and P0430 indicate catalyst efficiency below threshold. Contributing factors include oil consumption allowing oil to coat the catalyst material and normal thermal degradation.
Replace the affected catalytic converter assembly. Due to the integrated manifold/catalytic converter design, this is an expensive repair. Use OEM or CARB-compliant converters. Address any oil consumption issues first to protect the replacement converters from premature failure.
Est. Cost: $1,000 - $3,000HVAC Blend Door Actuator Failure
The HVAC blend door actuators can fail, producing a clicking or tapping noise from behind the dashboard when the climate control adjusts temperature. The system may blow only hot or only cold air regardless of the temperature setting. The dual-zone climate control system uses multiple actuators that can fail independently.
Diagnose which blend door actuator has failed by listening for the clicking noise and testing each climate zone independently. Replace the failed actuator. Some actuators require partial dashboard disassembly for access, particularly the one behind the center console. OEM actuators are recommended for longevity.
Est. Cost: $200 - $600
