Understanding the Infiniti G37’s Lasting Appeal
The Infiniti G37 didn’t just appear out of nowhere; it was the evolution of the beloved G35. It launched for the 2008 model year as a coupe, followed by a sedan and a striking hardtop convertible in 2009 . At its core, it was built on Nissan’s FM platform, sharing its DNA with the legendary 370Z sports car . This meant one thing: the driving dynamics were going to be special.
Living with the 3.7L V6 Engine
The true star of the show is the VQ37VHR 3.7-liter V6 engine. You feel the difference the moment you press the accelerator. With 330 horsepower in the coupe and 328 horsepower in the sedan, it delivers a smooth, linear surge of power that makes every on-ramp feel like a racetrack . The sound it makes is pure music to an enthusiast’s ear. More importantly, this engine is known for its durability. It’s a high-point in Infiniti’s history and can reliably handle its own power, and even a few bolt-on modifications, for many miles . This is the kind of engine that, with regular maintenance, can easily surpass 150,000 miles.
A Driver-Focused Cockpit
Step inside, and you’re greeted by a cabin that feels built around you. While the dual-screen infotainment might seem dated now, the interior is still a nice place to be. The leather-appointed seats, available sport stitching, and high-quality materials give it a premium feel that rivals its luxury competitors from Audi or BMW . It’s a car that feels special.
Reliability and Upkeep: What to Expect
Here’s the thing about owning a used luxury car—reliability is key, and the G37 delivers. It has an above-average reliability rating, ranking 8th out of 31 luxury midsize cars, according to RepairPal .
Expected Annual Maintenance Costs
The average annual repair cost for a G37 is around $540, which is notably lower than the average of $739 for other luxury midsize cars . This is a huge selling point. The frequency of repairs is about average, but the issues are less likely to be severe compared to other cars in its class . This is because its components are shared with the Nissan 370Z, making parts and service more accessible and affordable than those for a BMW or Audi.
Common Problems to Look Out For
While the G37 is generally robust, it does have a few quirks that are well-documented in the community.
- Cracking Dashboard: This is one of the most common complaints across all model years. The dashboard material can crack, shrink, or even become sticky in hot climates . It’s a cosmetic issue, but a costly one to fix.
- Sunroof Drain Clogs: A blocked sunroof drain can lead to water leaking into the cabin, a problem that plagues many G37s .
- Passenger Airbag Sensor: The sensor in the passenger seat can malfunction, causing the airbag warning light to turn on .
- Convertible Roof Mechanism (G37 Convertible): If you’re looking at a convertible, be very careful. The complex three-piece folding hardtop was a marvel of engineering but can be a source of expensive problems. Issues with the control module, sensors, and alignment are common, and repairs can be significant .
The Best and Worst Model Years
- Best Years: The 2011, 2012, and 2013 models are generally considered the sweet spot . These later models benefited from a switch to a more robust oil gasket, reducing the risk of low oil pressure. They also got a subtle facelift in 2010 with updated headlights and a grille, and improvements to the infotainment system .
- Worst Years: The earliest models, 2008 and 2009, are the ones to be most cautious about . Some very early coupes had a less refined five-speed automatic transmission before the seven-speed became standard . They also seem to suffer more from the infamous dashboard cracking issue.
Market Prices: Finding Your Deal
This is where the G37 really shines. The depreciation curve has flattened, meaning you can get an incredible amount of car for your money. Prices vary greatly based on condition, mileage, location, and whether you want a coupe, sedan, or convertible.
Current Average Prices
- Sedan: The average selling price is around $10,800 .
- Coupe and Convertible: You can find coupes in good condition for $8,000 to $15,000 . Convertibles tend to be in a similar range, with well-kept examples around $8,000 to $11,000 .
- IPL (Infiniti Performance Line): These rare, more powerful models (348 hp) command a premium .
Factors Affecting Price
- Mileage: Look for a car with fewer than 100,000 miles for the best long-term reliability.
- Maintenance Records: A car with a full service history is worth a premium. This shows the car was cared for and that critical fluids and components were changed on time.
- Number of Owners: Fewer owners usually suggests a better-cared-for vehicle .
- Accident History: Always get a vehicle history report.
Conclusion: The Verdict
