The 2010 Infiniti G37, built on the VQ37VHR 3.7-liter V6 platform, is known for strong performance but has some issues that buyers and owners commonly note as mileage climbs. Transmission behavior, oil consumption, electrical glitches, and wear in suspension and brakes appear most frequently in reports and maintenance discussions.
The following overview groups typical concerns by system, drawing on owner forums, maintenance notes, and recall checklists. Individual results vary by vehicle history, maintenance, and driving conditions. Always verify a used G37’s history and have a trusted technician inspect any car before purchase.
Engine and powertrain
The issues below cover engine and drivetrain components, where problems often surface as mileage grows or with insufficient service. The list highlights common symptoms and what to watch for during inspection or a test drive.
- Transmission and driveline: Some G37 models experience rough or delayed shifting with the seven-speed automatic, occasional shudder at low speeds or during upshifts, and in rare cases transmission failure. Symptoms may improve with software updates or transmission service, but persistent trouble warrants a dealership diagnosis and, if needed, torque converter or valve body service.
- Oil consumption: Owners sometimes report higher-than-expected oil use at higher mileage. Symptoms include frequent top-ups and warning lights. Regular oil level checks and using the recommended synthetic oil is advised; if consumption is excessive, a dealer inspection (and possibly a bulletin-based repair) may be indicated.
- Timing chain and engine noise: Some engines show faint ticking or rattling noises that can be associated with timing chain tensioners, guides, or related wear. A mechanic should verify proper tension and chain condition, as prolonged issues can lead to more serious engine concerns. Addressing faulty components early can prevent further damage.
- Misfires and fuel delivery: Misfires or rough idle can occur from coil packs, spark plugs, or injector-related issues. Diagnostics (codes and misfire history) help target the exact culprit and guide repair.
Careful maintenance and prompt attention to any unusual engine sounds, performance changes, or warning lights can help mitigate these risks. A well-documented service history with timely oil changes and component replacements often correlates with smoother operation.
Electrical and electronics
Electrical and infotainment-related problems are a common theme in reports about the 2010 G37. The following items cover issues owners may notice in daily driving or during infotainment use.
- Infotainment and navigation failures: Navigation screens freezing or intermittently failing, radio glitches, or touchscreen/responding issues have been reported in some cars.
- Instrument cluster and gauges: Flickering or non-functioning gauges, or intermittent digital readouts, can occur as components age.
- Battery drain and charging: Occasional battery drain or alternator-related trouble has been noted, especially in cars with aging electrical components or aftermarket accessories.
- HVAC control and comfort systems: Blower motor or blend door actuator failures can cause inconsistent heating or cooling performance.
- Keyless entry and door electronics: Issues with key fobs, door locks, or memory seat electronics may appear and may require module or sensor replacements.
Electrical maladies often share root causes like aging connectors, failed relays, or software glitches. A vehicle-specific diagnostic scan can pinpoint exact fault codes and guide repair decisions.
Suspension, brakes, and interior wear
Wear and performance concerns in the suspension, braking system, and interior trim are common as the G37 ages, particularly with higher mileage and sporty driving styles. The items listed below reflect typical observations from owners and technicians.
- Suspension components: Worn control arm bushings, struts/shocks, or sway bar links can cause clunks, creaks, or imprecise handling. Uneven tire wear can accompany worn components.
- Brake system and ABS: Premature brake-pad wear, rotor scoring, or ABS/vehicle stability lights can appear if wear is uneven or sensors are bent/faulty. Brake fluid leaks or worn calipers may also surface with age.
- Interior and trim quality: Leather seats and trim surfaces may show cracking or wear under daily use, and some owners report switch panel or wood-grain veneer fading or peeling in longer ownerships.
Regular inspections and timely replacement of worn parts help preserve ride quality and safety. Addressing suspension and braking issues promptly is especially important for a performance-oriented coupe or sedan like the G37.
What to look for when buying a used 2010 G37
When shopping for a used G37, use this checklist to assess condition, service history, and potential risk areas. A thorough pre-purchase inspection can save future headaches and expense.
- Complete service history: Look for regular oil changes, transmission service, brake work, and any recalls or TSBs completed. Gaps in maintenance can signal future problems.
- Test-drive performance: Note smooth acceleration, absence of transmission shudder or harsh gear changes, steady idle, and no unusual noises from the engine or suspension during the drive.
- Oil consumption and leaks: Check for oily residue in the engine bay, signs of oil leaks, and the owner’s reporting of oil top-ups, which may indicate a broader issue.
- Electrical systems check: Confirm operation of the radio, navigation, gauges, lights, HVAC, and keyless entry. Look for warning lights that stay on after startup.
- Recall and service bulletin status: Run a VIN check to ensure all applicable recalls have been addressed and any necessary software updates are installed.
- Brakes and tires: Inspect rotor surface, pad thickness, and tire tread; uneven wear can reveal alignment or suspension problems.
- Suspension and steering: Look for abnormal tire wear, clunks, or pulling to one side that could indicate worn components or alignment issues.
- Underbody and engine bay: Check for fluid leaks, corrosion, and damaged harnesses or connectors near the engine, transmission, and exhaust.
- VIN-based checks: Verify any open recalls or dealership campaigns tied to the specific car’s VIN for peace of mind.
- Ownership history: Consider previous ownership patterns, accident history, and whether the car has been tracked or used for aggressive driving, which can stress components.
Armed with a detailed inspection and history, you’ll be better positioned to negotiate and to plan any needed repairs or future maintenance after purchase.
Maintenance tips to reduce common problems
Proactive maintenance can help mitigate many of the issues associated with the 2010 G37. The following actions are commonly recommended by technicians and experienced owners.
- Follow the factory maintenance schedule, including timely oil changes with the specified grade of synthetic oil.
- Monitor oil level regularly, especially if the car has higher mileage, and address any consumption concerns early with a professional diagnosis.
- Keep the transmission fluid at the proper level and have shifts and the torque converter checked if you notice roughness or slipping.
- Address electrical issues promptly, running a diagnostic to identify fault codes and updating software where applicable.
- Have suspension components inspected at intervals and replace worn bushings, links, or shocks to maintain handling and tire life.
- Inspect brakes routinely, replace pads/rotors as needed, and ensure sensors and ABS components are functioning.
- Keep HVAC and climate-control components clean and service blend doors or blower motors if climate performance diminishes.
- Check recalls and service campaigns using the vehicle’s VIN, and have any required work completed by an authorized dealer.
Routine care, attentive monitoring, and timely repairs can help preserve the G37’s performance and reliability over time.
Summary
The 2010 Infiniti G37 can deliver strong performance and a refined driving experience, but owners frequently note issues in the powertrain, electronics, and suspension as mileage accumulates. Thorough pre-purchase checks, a clear maintenance history, and proactive maintenance are the best strategies to minimize problems and maximize enjoyment of this sporty Infiniti.
