What Problems Does the 2008 Infiniti G37 Have?
Frequently reported problems for the 2008 Infiniti G37 often revolve around oil consumption. Some owners have reported excessive oil consumption, particularly in earlier models. This can lead to engine damage if not monitored and addressed. Other common issues include: worn suspension components (bushings, control arms), especially in areas with rough roads; potential for valve cover gasket leaks, leading to oil leaks; and issues with the automatic transmission, such as rough shifting or slipping, though this is less common. Some owners have also reported problems with the power windows and door lock actuators.
While not a widespread issue, some G37s experienced issues with the direct adaptive steering system (DAS), though this was more prevalent in later models that featured this technology and not the 2008 model. Recalls for the 2008 G37 were issued for issues such as potential fuel leaks due to improperly manufactured fuel tube protectors and brake light switch malfunctions. Long-term reliability concerns center around the longevity of the VQ37VHR engine, which, while generally robust, can suffer from oil consumption issues as it ages if maintenance is neglected. Regular maintenance, including timely oil changes, is crucial for preventing these problems.

Regular maintenance, including timely oil changes, is crucial for preventing these problems.
How long will the 2008 Infiniti G37 last?
With proper maintenance, a 2008 Infiniti G37 can easily reach 200,000 miles or more. Many owners report exceeding this mileage with regular oil changes, fluid flushes, and timely repairs. Years of service can easily extend beyond 15 years with diligent upkeep. Long-term durability depends heavily on maintenance habits. Weaknesses that emerge over time include increased oil consumption, wear on suspension components, and potential issues with electrical systems (sensors, actuators). Rust can also become a concern in regions with harsh winters and road salt use. Consistent care is the key to maximizing the lifespan of a G37.
What Technology & Safety Features are Included?
The 2008 Infiniti G37 featured a decent array of tech and safety features for its time. Standard features included keyless entry, automatic climate control, a premium audio system with CD player and auxiliary input, and power windows and locks. Higher trims offered features like a navigation system with a screen integrated into the dashboard, Bluetooth connectivity, and a rearview camera. Entertainment options included satellite radio.
Driver-assistance features were limited compared to modern vehicles, but included features like traction control and stability control. Safety features consisted of anti-lock brakes (ABS), electronic brake-force distribution (EBD), brake assist, and a suite of airbags, including front, side, and curtain airbags.
Optional features included Intelligent Cruise Control (ICC), which could maintain a set distance from the vehicle ahead. Crash-test ratings from the IIHS (Insurance Institute for Highway Safety) and NHTSA (National Highway Traffic Safety Administration) were generally good. The G37 typically earned high marks for frontal and side impact protection. While specific ratings may vary slightly based on body style, the G37 offered solid crash protection for its era. It's worth noting that technology and safety standards have advanced significantly since 2008.

2008 Infiniti G37 Prices and Market Value
When new, the 2008 Infiniti G37 ranged from approximately $32,000 to $45,000, depending on the trim level and options. Current used market prices typically range from $5,000 to $15,000, depending on condition, mileage, and location. The G37 has depreciated significantly over time, as expected for a luxury vehicle of this age. Factors affecting resale value include the vehicle's condition, maintenance history, mileage, and trim level. Sport trims and those with desirable options (navigation, premium audio) generally command higher prices. Lower mileage examples in excellent condition fetch the highest values, while those with mechanical issues or cosmetic damage sell for significantly less. Color can also influence resale, with more popular colors holding their value better.
2008 Infiniti G37 Cost of Ownership
The 2008 Infiniti G37 is generally considered moderately costly to own. Insurance costs can be higher than average due to its sporty nature. Fuel costs are also above average, as it requires premium gasoline. Maintenance and repair costs can be significant, especially as the vehicle ages. Parts can be more expensive than for mainstream brands, and labor costs at specialized repair shops can be high. While not the most economical choice, it offers a balance of performance and luxury that may justify the higher ownership costs for some buyers.

The 2008 Infiniti G37 is a good choice for buyers seeking a sporty and luxurious car at an affordable price. It's ideal for enthusiasts who appreciate a powerful engine and engaging driving dynamics. However, potential buyers should be aware of potential maintenance costs and potential oil consumption issues. It's generally not recommended to buy it new at this point, as only used models are available. It's worth buying used if you can find a well-maintained example with a clean service history. The Sport trim is particularly desirable for its upgraded brakes and suspension. A pre-purchase inspection by a qualified mechanic is highly recommended to assess the overall condition and identify any potential problems.
