The Best Years For Infiniti G37 And Some To Avoid

The Infiniti G37, a luxury sports sedan/coupe, has garnered a loyal following for its blend of performance, style, and value. However, not all model years are created equal. This guide dives deep into the G37's production run, highlighting the best years to buy and which ones to potentially avoid, ensuring you make an informed decision in 2024.

Detailed Explanations

2008: First Year of the G37, Updated VQ37VHR Engine, Improved Interior

The 2008 Infiniti G37 marked a significant step up from the G35. The introduction of the VQ37VHR engine brought increased horsepower and torque, making it a more engaging driving experience. The interior also received a welcome upgrade in terms of materials and design. However, being the first model year, some early production quirks were present.

Potential Issues/Concerns: Early Production Issues, Potential for Oil Consumption in Some Engines

As with many first-year models, the 2008 G37 had its share of teething problems. Oil consumption was a relatively common issue reported by owners, potentially requiring more frequent oil changes. Early production vehicles might also have experienced minor electrical or mechanical glitches.

2009: Minor Refinements, Improved Technology Options

The 2009 G37 saw minor refinements to address some of the initial concerns from the 2008 model year. Technology options were also improved, offering a more modern driving experience.

Potential Issues/Concerns: Same Potential Oil Consumption Issues as 2008

While some refinements were made, the 2009 G37 still carried the potential for oil consumption issues, albeit perhaps to a lesser extent than the 2008 model. Thorough inspection of maintenance records and a pre-purchase inspection are crucial.

2010: Minor Cosmetic Changes, Improved Navigation System

The 2010 G37 received minor cosmetic tweaks and an improved navigation system, enhancing its appeal. It represented a subtle evolution of the platform.

Potential Issues/Concerns: Some Reports of Timing Chain Issues, Particularly in Early Production Models

The 2010 model year is where reports of timing chain issues started to surface. This is a significant concern, as a failing timing chain can lead to catastrophic engine damage. The issue seemed more prevalent in early production models of the 2010 G37. Listen for any unusual noises like a rattling sound upon startup as this could be a warning sign.

2011: No Major Changes

The 2011 G37 was largely unchanged from the 2010 model. It continued to offer a solid driving experience and a luxurious interior.

Potential Issues/Concerns: Timing Chain Issues Still a Possibility, Although Less Prevalent

While the timing chain issue was still a possibility, it appeared to be less prevalent in the 2011 model year compared to the 2010. Nevertheless, it's crucial to be aware of this potential problem and perform a thorough inspection before purchasing.

2012: Refreshed Front Fascia, Minor Interior Updates

The 2012 G37 received a refreshed front fascia and minor interior updates, giving it a more modern and aggressive look. This facelift helped keep the G37 competitive in the luxury sports sedan/coupe market.

Potential Issues/Concerns: Potential for Gallery Gasket Failure Leading to Oil Leaks

The 2012 model year saw the emergence of another potential issue: gallery gasket failure. These gaskets, located within the engine, are prone to leaking oil over time. This can lead to decreased oil pressure and potential engine damage if left unaddressed.

2013: No Major Changes

The 2013 G37 was the final year of production before the model was rebranded as the Q50. It remained largely unchanged from the 2012 model.

Potential Issues/Concerns: Gallery Gasket Issues Persist

Unfortunately, the gallery gasket issues that plagued the 2012 model persisted in the 2013 G37. This is a critical area to inspect before purchasing a 2012 or 2013 model.

Frequently Asked Questions

Which G37 year is the most reliable? The 2011 G37 is often considered the most reliable, as it addressed some of the early production issues and had fewer reported timing chain problems than the 2010 model.

What is the biggest problem with the G37? The most significant potential problems are timing chain issues (primarily 2010-2011) and gallery gasket failures (2012-2013), both of which can lead to expensive repairs.

How long will a G37 last? With proper maintenance, a G37 can easily last 200,000 miles or more. Regular oil changes and addressing any issues promptly are crucial for longevity.

Is the G37 expensive to maintain? Maintenance costs can be slightly higher than average due to the G37 being a luxury vehicle, but it's generally considered reasonable compared to other cars in its class.

What should I look for when buying a used G37? Check the service history, inspect for oil leaks (especially around the gallery gaskets), listen for timing chain noise on startup, and get a pre-purchase inspection by a qualified mechanic.

Conclusion

Choosing the right year of the Infiniti G37 can significantly impact your ownership experience. While the 2008-2009 models offered a great value, potential oil consumption issues exist. The 2010 and 2011 models are susceptible to timing chain problems, making the 2011 model the potentially better choice of the two. The 2012 and 2013 models, while stylish, are known for gallery gasket failures. A thorough pre-purchase inspection is essential, regardless of the year you choose. Prioritize well-maintained examples with documented service histories to enjoy the G37's performance and luxury for years to come.
