Problems owners report
- Very frequentPoor fuel economy
Real-world mileage reported around 18 MPG, requires premium fuel.
- RecurrentInterior quality and aging
Described as dated, with hard plastics, a "playschool plastic" steering wheel feel, and lacking modern safety tech (backup camera, sensors) in older models.
- RecurrentHigh maintenance costs compared to mainstream brands
While cheaper than German rivals, parts and repairs are noted as more expensive than for a typical Honda or Toyota.

The version owners recommend
G37 Coupe (specifically the VQ37VHR engine): The G37 is consistently favored over the G35 for its more refined VQ37VHR engine, which is described as having a better torque curve, a higher 7500 RPM redline, and being "leaps and bounds better." The coupe body style is often discussed in the context of sportiness and styling. For all-wheel-drive models, the 'x' trim (G37x) is noted for its capability in colder climates.
Competitors to consider
Owners compare it most often with the BMW 3 Series (E90 328i, 335i), Lexus IS 350, Lexus RC 350, Ford Mustang and Subaru BRZ/Toyota 86.

Overall sentiment
Owner sentiment is strongly positive, with the G35 and G37 consistently praised as high-value, reliable, and fun-to-drive sports sedans and coupes. The VQ-series engines (VQ35DE, VQ35HR, VQ37VHR) are highlighted for their robust power, smoothness, and durability, with many reports of them lasting well beyond 200,000 miles with proper maintenance. The driving experience is described as engaging, with good handling that feels planted and confident at speed. The cars are widely regarded as offering a compelling blend of performance, luxury, and Japanese reliability at a significantly lower cost of ownership compared to German rivals. Criticisms are focused on specific shortcomings rather than fundamental flaws: notably poor fuel economy, an interior quality that feels dated or less premium over time, and for some, a driving experience that is less raw or connected than dedicated sports cars.
Positioning vs competitors
Positioned as a more reliable and cost-effective alternative to German performance sedans (BMW 3 Series, Audi S4), trading some interior refinement and ultimate driving engagement for lower maintenance costs and proven long-term durability. Compared to the Lexus IS 350, the G37 is viewed as the more performance-oriented option, while the Lexus is seen as having slightly better fuel efficiency and potentially superior interior quality. Against dedicated sports cars like the BRZ/86 or 370Z, the G37 is considered a more refined, comfortable, and practical daily driver, albeit heavier and less agile. It is frequently seen as offering superior power and a more complete package than the BRZ, but lacking its pure, driver-focused handling.
Recommended configurations
Manual transmission is implied as desirable for engagement but not extensively detailed. The VQ37VHR engine (G37) is strongly recommended over earlier VQ35 engines. All-wheel drive (x models) is suggested for those in regions with winter weather. A well-documented service history is emphasized as critical when purchasing a used example. Owners recommend budgeting for higher fuel costs.
General recommendations
Highly recommended as a used performance value for buyers seeking a balance of power, reliability, and lower running costs than German competitors. Ideal for enthusiasts who prioritize a strong, naturally aspirated V6 and engaging rear-wheel-drive (or AWD) dynamics but do not require the sharpest handling or most modern interior. Not recommended for buyers prioritizing fuel efficiency, as real-world gas mileage is reported to be poor (around 18 MPG) and requires premium fuel. A thorough pre-purchase inspection is advised, with attention to maintenance records. The platform has extensive aftermarket support for modifications.
Remarks
The "Infiniti G" discussion in owner feedback primarily encompasses the G35 (2003-2006) and G37 (2007-2013) generations, with a clear consensus that the G37 represents a meaningful upgrade. The platform is closely related to the Nissan 350Z/370Z, sharing engines and core components, which contributes to its performance reputation and aftermarket support. Positive reliability anecdotes are numerous, but often contingent on rigorous maintenance. The model was effectively succeeded by the Q60, which some owners feel compromised the handling dynamics of the G37. Analysis based on approximately 24 substantive owner discussions focused on the vehicle.
