The 2013 Infiniti G37 has 16 known issues compiled from NHTSA recalls, manufacturer TSBs, and owner forum reports. 6 issues are rated critical: VVEL Actuator and Control Module Failure Causing Limp Mode and Timing Chain Stretch and Guide Wear on VQ37VHR and Oil Gallery Gasket Leak and Electronic Steering Lock Failure and Concentric Slave Cylinder Failure (Manual) and Crankshaft Position Sensor Failure Causing Hot Stall and No-Start (P0335). Prospective buyers should inspect for these issues and factor potential repair costs into their purchase decision. Regular maintenance following the manufacturer's schedule helps prevent many common problems.
Repair costs for known Infiniti G37 issues range from $0 to $7,000, depending on the specific problem and whether you choose DIY or professional repair. The most critical issue, VVEL Actuator and Control Module Failure Causing Limp Mode, typically costs $600-$3,000 to repair. Au7o provides step-by-step DIY maintenance guides that can help reduce repair costs.
The VQ37VHR uses Variable Valve Event and Lift, a mechanical system on the intake side that varies lift continuously through an actuator motor driving a control shaft, managed by its own control module. When the actuator motor, the control shaft position sensor, or the VVEL modul… Repairs typically run $600-$3,000. Severity: high.
The VQ37VHR runs three timing chains — a primary and two secondaries — with plastic guides and hydraulic tensioners. The chains stretch and the guides wear, and because the tensioners rely on oil pressure to take up slack, any oil pressure loss or extended change interval acceler… Repairs typically run $1,800-$4,000. Severity: high.
The VQ37VHR engine develops oil leaks from the oil gallery gaskets located between the upper and lower oil pans. Oil seeps onto the exhaust, creating a burning smell and potential fire hazard if left unaddressed. Repairs typically run $400-$1,200. Severity: high.
Like the G35, the G37 suffers from electronic steering wheel lock actuator failures that prevent the vehicle from starting. The internal motor in the lock mechanism burns out or the control module loses communication with the BCM. Repairs typically run $300-$1,000. Severity: high.
Manual transmission G37s suffer from premature concentric slave cylinder (CSC) failure. The internal seal degrades, causing clutch fluid to leak into the bell housing and resulting in a soft or sinking clutch pedal. Repairs typically run $800-$2,000. Severity: high.
The crankshaft position sensor mounted on the transmission bell housing of the VQ37VHR is a documented failure point on G37s past about 80k miles. It typically fails when hot: the engine stalls after warm-up or extended driving, cranks without starting until it cools, then restar… Repairs typically run $80-$350. Severity: high.
The Hitachi coil-on-plug units on the VQ37VHR are a recurring failure item on higher-mileage G37s. Heat and electrical stress cause the coil body to blister or bulge, producing a random or single-cylinder misfire, rough idle and flashing check-engine light. Infiniti's bulletin IT… Repairs typically run $150-$900. Severity: medium.
Water entering the sunroof tray is meant to drain through four tubes routed down the A- and C-pillars. Debris blocks the drain nipples at the tray corners, the tray overflows, and water runs into the headliner and down the pillars into the cabin. Owners report soaked footwell car… Repairs typically run $0-$900. Severity: medium.
The 7-speed automatic introduced for the 2009 G37 developed a widely reported drivability complaint: a hard clunk on the 2nd-to-1st downshift when coasting to a stop, gear hunting/searching under light throttle, delayed or harsh upshifts when cold, and in some cases stored incorr… Repairs typically run $0-$250. Severity: medium.
The 2009-2013 G37 Convertible's retractable hardtop depends on a trunk-mounted hydraulic pump, multiple cylinders, and a trunk 'separator' (tonneau divider) that must be latched before the top will cycle. Common failures reported across the multi-part 'Convertible Top Issues' thr… Repairs typically run $350-$7,000. Severity: medium.
The FS6R31A 6-speed manual fitted to G37 Sport/6MT cars develops synchro grind, most often on 2nd, 5th and 6th (some report 3rd) during quick upshifts or when skipping gears. It is usually masked when shifting gently and shows up under spirited driving. Early in the car's life In… Repairs typically run $150-$4,500. Severity: medium.
Front hub bearings on the G37 (sedan, coupe and especially the heavier AWD G37x) fail well before most owners expect, typically between 50k and 90k miles. The symptom is a hum or drone above roughly 45-50 mph that changes pitch when the car is loaded in one direction (louder turn… Repairs typically run $200-$700. Severity: medium.
The hydraulic power steering circuit on the G37 develops leaks at the high-pressure hose, its crimped hard-line sections and the reservoir-side return hose as the rubber ages. Owners describe fluid coating the underside of the car, a whine from the pump when low, and difficulty p… Repairs typically run $150-$700. Severity: medium.
G37 fuel gauges commonly read wrong as the cars age: the needle sticks at half or full, drops suddenly, or the low-fuel light comes on with fuel remaining. The saddle-style tank uses a main and sub level sensor; wear on the float-arm resistor track in either sender produces errat… Repairs typically run $100-$500. Severity: low.
Owners across model years report the G37's air conditioning gradually blowing warm as refrigerant escapes, most often from the compressor shaft seal, the high-pressure service fitting or cutoff-switch O-rings, and occasionally the condenser. The system holds only about 1.1 lb of… Repairs typically run $150-$2,800. Severity: low.
On Bose-equipped G37s the trunk-mounted amplifier is the most common audio failure. Sound cuts out entirely or intermittently with no error on screen—the head unit, navigation and controls keep working, but nothing comes from the speakers. Owner diagnosis on G35Driver and MyG37 s… Repairs typically run $100-$800. Severity: low.
