What Problems Does the 2012 Infiniti G Sedan Have?
The 2012 Infiniti G Sedan, while generally considered reliable, does have a few reported issues that owners should be aware of. One of the more frequently mentioned concerns revolves around the transmission, particularly in the G37 models. Some owners have reported issues such as rough shifting, hesitation, or even premature failure, especially if the vehicle has been driven aggressively or maintenance has been neglected. While not a widespread epidemic, it's something to inspect closely during a pre-purchase inspection.
Another area to watch is the infotainment system. Like many vehicles of its era, the G Sedan's navigation and audio systems can sometimes exhibit glitches, such as freezing, unresponsiveness, or issues with Bluetooth connectivity. These are often minor annoyances but can be frustrating.
The suspension components, particularly the bushings and ball joints, can wear over time, leading to clunking noises or a less refined ride. This is not uncommon for a performance-oriented sedan with mileage, but it's worth checking for excessive play or wear.
Oil consumption has been noted by a small number of owners of the 3.7-liter VQ37VHR engine, though it's typically within acceptable manufacturer limits if monitored regularly. However, significant oil loss could indicate an issue.
Regarding recalls, there haven't been major widespread recalls specifically for the 2012 G Sedan that indicate a systemic flaw. However, it's always advisable to check the National Highway Traffic Safety Administration (NHTSA) website for any outstanding recalls pertaining to a specific vehicle's VIN.
In terms of long-term reliability, the G Sedan generally holds up well, especially if it has a documented history of regular maintenance. The V6 engines are robust, and the core mechanical components are sound. However, as with any aging luxury vehicle, expect that some wear-and-tear items like sensors, seals, and suspension parts may eventually require attention.

How long will the 2012 Infiniti G Sedan last?
Based on owner data and typical maintenance, a well-maintained 2012 Infiniti G Sedan can reasonably achieve between 150,000 to 200,000 miles, and often more, before major component overhauls become necessary. Owners who adhere to scheduled maintenance, including regular oil changes, fluid flushes, and timely replacement of wear items, will experience the best long-term durability. The robust V6 engines are a testament to Infiniti's engineering. However, over time, certain components like suspension bushings, catalytic converters, and potentially the transmission (especially in higher-mileage or harder-driven examples) may require attention. The interior generally holds up well, maintaining its premium feel if cared for. Proactive maintenance is key to extending the vehicle's service life and avoiding costly repairs.
What Technology & Safety Features are Included?
The 2012 Infiniti G Sedan offered a good array of technology, entertainment, and safety features for its time, with many desirable options available. Standard tech often included a multi-function display, keyless entry and ignition, and an AM/FM/CD audio system with auxiliary input.
Entertainment: Higher trims and optional packages significantly enhanced the entertainment experience. Available features included a premium Bose audio system with multiple speakers, USB/iPod connectivity, and Bluetooth hands-free phone capability. An optional hard-drive-based navigation system was a popular upgrade, often bundled with a 7-inch or 8-inch touchscreen display and real-time traffic information.
Driver-Assistance Features: Infiniti was ahead of the curve with some advanced driver-assistance systems. Optional features could include a rearview camera, front and rear parking sensors, adaptive cruise control (which could maintain a set distance from the vehicle ahead), and Intelligent Cruise Control. Blind Spot Warning (BSW) and Blind Spot Intervention (BSI) systems were also available on some models, helping to alert the driver to vehicles in their blind spots and even nudge the vehicle back into its lane if necessary.
Safety Features: Standard safety equipment included front airbags, front side-impact airbags, and roof-mounted curtain side-impact airbags. Anti-lock Braking System (ABS), Electronic Brake-force Distribution (EBD), and Brake Assist were also standard. Vehicle Dynamic Control (VDC) and Traction Control System (TCS) were designed to help the driver maintain control in slippery conditions.
Crash-Test Ratings: The 2012 Infiniti G Sedan generally performed well in crash tests. The Insurance Institute for Highway Safety (IIHS) awarded the 2012 G Sedan with a Top Safety Pick rating. It received good ratings in frontal offset, side impact, and roof strength tests. The National Highway Traffic Safety Administration (NHTSA) also provided good overall safety ratings, though specific star ratings varied slightly by test category.
Entertainment: Higher trims and optional packages significantly enhanced the entertainment experience.

2012 Infiniti G Sedan Prices and Market Value
When new, the 2012 Infiniti G Sedan had an MSRP that typically ranged from approximately $32,000 for a base G25 to over $45,000 for a well-optioned G37 x AWD model. Depreciation on the G Sedan was moderate for a luxury vehicle, with a significant drop in value occurring within the first few years of ownership, typical for the segment. Currently, the used market price for a 2012 G Sedan can vary widely, generally ranging from $7,000 to $14,000, depending heavily on mileage, condition, trim level (G37 models command higher prices), maintenance history, and overall market demand. Factors affecting resale value include the presence of desirable options like navigation and premium audio, a clean accident history, and well-documented maintenance records. The G37's stronger performance generally leads to better retained value compared to the G25.
2012 Infiniti G Sedan Cost of Ownership
Owning a 2012 Infiniti G Sedan presents moderate long-term costs. Insurance premiums can be higher than for a non-luxury sedan due to its premium nature and performance capabilities. Fuel costs, especially for the G37, can be substantial given its V6 engine and relatively lower MPG. Routine maintenance, such as oil changes and tire rotations, is comparable to other luxury vehicles. However, repair costs for parts and labor can be more expensive than mainstream brands, particularly for specialized components or if services are performed at a dealership. Overall, the G Sedan is neither exceptionally economical nor prohibitively costly to own, fitting within the typical range for a premium sedan of its era, with careful maintenance being key to managing expenses.

How Does the 2012 Infiniti G Sedan Compare to Other Sedan?
The 2012 Infiniti G Sedan competed in a crowded segment, primarily against the BMW 3 Series, Audi A4, Mercedes-Benz C-Class, and the Acura TL. In terms of performance, the G37 variant, with its potent 3.7-liter V6, often outperformed its rivals, offering sharper acceleration and a more engaging driving experience than many, especially the Audi A4 and Mercedes C-Class of that era. The BMW 3 Series was its closest competitor for sporty handling.
When it comes to features, the G Sedan offered a strong list of standard and optional amenities, often rivaling or exceeding its German competitors in value. The available navigation system, premium audio, and advanced driver aids were competitive. However, the infotainment system's interface was starting to feel dated compared to newer systems introduced by rivals around 2012.
Reliability is a mixed bag. While Infiniti's V6 engines are generally robust, the G Sedan sometimes lagged behind the Acura TL in long-term reliability studies, which was known for its exceptional dependability. The German rivals could also present more costly repair bills as they aged.
Price-wise, the Infiniti G Sedan typically offered a more compelling value proposition. It provided comparable or superior performance and luxury for a lower price point than its German counterparts when new, and this trend often continues on the used market. The Acura TL also represented excellent value and reliability.
Similar Alternatives: The Acura TL (especially the SH-AWD model) is a strong alternative, offering comparable performance, excellent reliability, and a luxurious interior, often at a similar or slightly lower price on the used market. The Lexus IS 350 is another contender, providing a blend of performance and legendary Lexus reliability, though it might feel slightly less sporty than the G37.
Potentially Better Alternatives: If ultimate driving dynamics and brand prestige are paramount, a similarly priced used BMW 3 Series (E90 generation) would be a strong contender, though maintenance costs could be higher. For those prioritizing bulletproof reliability above all else, the Acura TL is hard to beat.

Final Verdict: Is the 2012 Infiniti G Sedan a Good Sedan?
The 2012 Infiniti G Sedan is ideal for individuals or small families seeking a blend of spirited performance, upscale comfort, and a touch of luxury without the exorbitant price tag of some European competitors. It's particularly well-suited for drivers who appreciate engaging handling and a powerful engine, especially in the G37 trims. It is certainly worth considering as a used vehicle, offering excellent value.
Buying a G Sedan is most advisable on the used market. Focus on the G37 models for the best performance experience. Thoroughly inspect any vehicle for transmission health and maintenance records. If you prioritize ultimate reliability and lower running costs, alternatives like the Acura TL might be a better fit. However, for a sporty, luxurious, and relatively well-built sedan that offers significant bang for your buck, the 2012 Infiniti G Sedan is a compelling choice.
