Yes. The Infiniti G37 is generally considered a reliable used luxury option, especially when it receives regular maintenance and is inspected for common wear items.
To understand reliability in context, it helps to review the G37’s design, model-year differences, typical maintenance needs, and what owners report after years behind the wheel. The G37, which followed the G35 in the late 2000s, relies on Nissan’s durable V6 architecture and a proven chassis, but like any aging luxury car, its longevity depends on care, service history, and recall compliance.
What makes the G37 reliable
Powertrain and overall durability
Several factors contribute to the G37’s reputation for reliability: a robust V6 engine, a well-proven drivetrain, and solid build quality. Below are the main strengths cited by owners and reviewers.
- Durable 3.7-liter VQ engine: The VQ37VHR engine is known for longevity when properly maintained with timely oil changes and cooling system care.
- Transmission options: Earlier models used a smooth automatic, with later versions offering refined shifts that reduce wear when serviced regularly.
- Chassis and steering: A composed ride and predictable handling contribute to a confident ownership experience with manageable maintenance needs.
- Parts availability and support: Infiniti/Nissan parts are widely available, supporting reasonable maintenance costs for a luxury-brand vehicle.
These strengths point to a vehicle that can deliver many years of service if properly cared for, with a maintenance routine that focuses on the basics: oil, filters, brakes, and fluid checks.
Common concerns and what to watch by model year
Some owners report issues that are more common in certain years or configurations. Being aware of these can help with purchasing decisions and maintenance planning.
- Maintenance-sensitive wear items: Expect typical aging wear on components like brakes, suspension bushings, and tires; timely replacement preserves ride quality and safety.
- Engine cooling and seals: Regular cooling system maintenance helps prevent overheating and related gasket or hose failures that can occur with age.
- Electrical and infotainment quirks: Some units experience intermittent electrical or display glitches; software updates and diagnostic checks can address most concerns.
- Transmission behavior: In higher-mileage examples, smooth shifting depends on regular transmission fluid servicing and the absence of hard-shift complaints.
It’s important to verify recalls and service campaigns through NHTSA or the manufacturer, and to review the vehicle’s maintenance history, since reliability issues are often tied to maintenance rather than inherent design flaws.
Maintenance costs and ownership expectations
Compared with some European luxury rivals, the G37 offers relatively reasonable maintenance costs for a luxury car, thanks to shared Nissan parts and a broad service network. Expect typical premium-brand costs for tires, brakes, and scheduled maintenance, with potentially higher expenses for dealership-specific electronics work or specialty components as the vehicle ages.
Recall history and safety notices
Over its production span, the G37 lineage was subject to recalls including airbag inflators and other safety campaigns that affect all vehicles built during certain periods. Always check the VIN against NHTSA and Infiniti recall notices before purchase and ensure repairs are completed.
Bottom line
For buyers seeking a used luxury sedan or coupe with a strong V6, refined ride, and a reputation that generally skews toward reliability, the Infiniti G37 remains a solid option when properly maintained. With routine care and attention to known wear items, many owners report high satisfaction and decent long-term value.
Summary: The Infiniti G37 is generally reliable for a used luxury model, especially when maintenance is kept up and recalls are addressed. The model years 2009–2013 are the core window for reliability considerations, with particular attention to engine and transmission health as mileage climbs. Regular maintenance, informed buying, and timely recall compliance can yield a durable, satisfying vehicle in its class.
