Detailed Explanations
2003-2004 (First Generation): These models marked the debut of the Infiniti G35. They boasted a potent VQ35DE engine, offering a thrilling driving experience. However, these early models were known for oil consumption issues. Regular checks and maintenance were essential to mitigate this problem. Additionally, the automatic transmissions in these early years could be prone to issues, and rust might be a concern, especially in regions with harsh winters.
2005-2006: These model years brought minor styling updates and improved interior materials, enhancing the overall appeal of the G35. Despite these improvements, the oil consumption issues from the earlier models persisted. Potential buyers should be aware of this and consider a pre-purchase inspection to assess the engine's condition. Rust remained a potential concern as well.
2007-2008 (Second Generation): This generation represented a significant upgrade with a redesigned exterior and interior. The introduction of the VQ35HR engine brought increased power and responsiveness. While oil consumption was less prevalent than in the first generation, it could still occur. A notable concern for these models was the potential for gallery gasket failure. This gasket, located within the engine, could leak, leading to oil pressure problems and potentially severe engine damage.
2009-2013: These years saw minor updates and improvements in technology features. However, the gallery gasket failure remained a potential issue. Furthermore, some higher mileage models might experience timing chain issues. A thorough inspection, including listening for any unusual engine noises, is recommended before purchasing a G35 from these years.
2014-2015 (Q40): The Q40 was essentially a rebadged G37, representing a continuation of the G37 line. Consequently, it shared the same potential issues as the G37, including the possibility of timing chain problems.
Best Years (Overall): 2011-2013 (G37): These model years are generally considered the best overall due to their refined features and lower risk of major issues compared to earlier models. The VQ37VHR engine is known for its reliability and performance. While no car is entirely immune to problems, the 2011-2013 G37 models offer a more secure and enjoyable ownership experience.
Years to Approach with Caution: 2003-2006 (G35): Due to the higher risk of oil consumption and rust, these model years should be approached with caution. A thorough pre-purchase inspection is crucial to assess the vehicle's condition and potential maintenance needs. While these models can still offer a good driving experience, be prepared for potential repairs and maintenance.
