What Problems Does the 2012 Infiniti G37 Have?
The 2012 Infiniti G37, while generally reliable, has several frequently reported problems and long-term concerns that potential owners should be aware of. One of the most significant and well-documented issues across various VQ37VHR engines, including the 2012 G37, is the failure of the gallery gasket. This gasket, located behind the timing cover, is made of paper or a weak composite material in earlier models (pre-2012, but still relevant to watch for even in 2012 as some early 2012 builds might have it, or it's a long-term wear item), which can degrade and lead to a loss of oil pressure. Symptoms include a low oil pressure warning light, engine knocking, and eventually severe engine damage. Repair is labor-intensive and costly.
Another common complaint involves the steering shaft, where a clunking or clicking noise can develop when turning the steering wheel, particularly at low speeds. This often indicates wear in the intermediate steering shaft or its bushings. While not a safety hazard in most cases, it's an irritating noise that requires repair.
HVAC system issues, specifically relating to blend door actuators, are also reported. This can lead to improper temperature control (e.g., only hot air or cold air from certain vents). Sunroof drain clogs can lead to water leaks into the cabin if not regularly maintained.
Some owners report higher than average oil consumption, though this is less prevalent in the 2012 model year compared to earlier VQ engines. Regular oil level checks are still advisable. Sensor failures, such as camshaft or crankshaft position sensors, can occasionally occur, leading to rough idling or stalling.
In terms of recalls, for the 2012 Infiniti G37, the most significant recall was related to the Takata airbag inflator issue, a widespread problem affecting many makes and models. This recall requires replacement of the affected airbag inflators due to the risk of them rupturing during deployment and potentially injuring occupants. Prospective buyers should always check a specific vehicle's VIN against the NHTSA recall database to ensure all outstanding recalls have been addressed.
Long-term reliability is generally good for the G37. The VQ engine is known for its durability, but proactive maintenance, especially regarding oil changes and fluid checks, is crucial. Suspension components like bushings and control arms may eventually need replacement as the vehicle ages, contributing to overall maintenance costs.

How long will the 2012 Infiniti G37 last?
With proper maintenance, the 2012 Infiniti G37 can reliably serve its owners for an impressive duration. Many G37s, particularly those meticulously cared for, easily exceed 150,000 to 200,000 miles, equating to 12-15+ years of service. The VQ37VHR engine is renowned for its durability, often being the last component to fail. However, long-term durability does hinge on consistent oil changes, fluid flushes, and addressing minor issues promptly. Weaknesses over time include the aforementioned gallery gasket issue, which can be catastrophic if ignored. Suspension components like control arm bushings, shocks, and struts will eventually wear out, leading to a less composed ride and requiring replacement around the 100,000-120,000-mile mark. Interior plastics and leather can also show wear, and electronic components may begin to fail with age, but these are generally manageable concerns for a well-maintained vehicle.
What Technology & Safety Features are Included?
The 2012 Infiniti G37, while offering a premium experience, featured technology that was respectable for its era but might feel somewhat dated by today's standards. Standard built-in tech included an intelligent key with push-button ignition, dual-zone automatic climate control, and an information display. Entertainment features typically included a six-speaker audio system with a CD player, auxiliary input, and satellite radio capability. Optional upgrades, often part of the Premium or Navigation packages, brought a premium 11-speaker Bose audio system, a hard-drive-based navigation system with a 7-inch touchscreen, Bluetooth phone connectivity, and a rearview camera.
Driver-assistance features, while not as comprehensive as modern vehicles, were available. These included an optional adaptive cruise control system (Intelligent Cruise Control) that could maintain a set distance from the car ahead. Rear parking sensors were also available, and a rearview camera was standard on the sedan and optional on coupe/convertible models, aiding in parking maneuvers.
In terms of safety, the 2012 G37 came well-equipped with standard features including six airbags (front, side, and full-length curtain), four-wheel anti-lock brakes (ABS), electronic brakeforce distribution (EBD), brake assist (BA), traction control, and Infiniti's Vehicle Dynamic Control (VDC) stability system.
Regarding crash-test ratings:
Overall, the G37 provided a solid foundation of safety features, with decent crash test performance for its time.

How Does the 2012 Infiniti G37 Compare to Other Convertible?
The 2012 Infiniti G37 often found itself in direct competition with established luxury sports sedans like the BMW 3 Series (E90/F30 generation), Audi A4/A5, Mercedes-Benz C-Class (W204), and the Lexus IS.
In terms of performance, the G37's 3.7L VQ V6 engine typically offered more horsepower than its naturally aspirated German rivals (e.g., BMW 328i, Mercedes C300) and even some turbocharged options, providing a visceral, engaging, and powerful driving experience. It often felt more raw and aggressive than the smoother Lexus IS. The BMW 335i, however, often had an edge in torque delivery and handling precision.
Regarding features, the G37 offered a strong list of standard amenities for its price point. It matched or exceeded many base models of its German rivals. However, the German brands often had more advanced and refined infotainment systems and a wider array of cutting-edge optional driver-assistance features for their time, though at a higher price. The Lexus IS often had a reputation for a quieter, more refined cabin.
Reliability is where the G37 held a strong position against its European counterparts. While not entirely problem-free (e.g., gallery gasket, steering shaft), its powertrain is generally robust, and maintenance costs are typically lower than BMW or Mercedes. The Lexus IS often had a slight edge in perceived bulletproof reliability, but the G37 wasn't far behind.
From a price perspective, both new and on the used market, the G37 offered a compelling value proposition. It was often significantly less expensive than a comparably equipped BMW, Audi, or Mercedes when new, and this value gap widened in the used market. This makes it a "bang for your buck" choice for performance luxury.
Alternatives:
The G37 often strikes a great balance, especially as a used vehicle.

- Audi A4/A5: For excellent interior quality, sophisticated AWD systems, and a more understated luxury, but potentially higher complexity for repairs.
- Hyundai Genesis Coupe (3.8L): A more budget-friendly, performance-focused alternative, though without the same level of interior refinement or luxury prestige.
The G37 often strikes a great balance, especially as a used vehicle.
Final Verdict: Is the 2012 Infiniti G37 a Good Convertible?
The 2012 Infiniti G37 is ideal for individuals seeking a powerful, engaging, and stylish luxury sports car without the premium price tag or potentially higher maintenance costs of its European rivals. It's perfect for enthusiasts who appreciate a strong V6 engine, rear-wheel-drive dynamics (or AWD versatility), and a well-appointed interior.
