The 2012 Infiniti G25 is a sophisticated entry-level luxury sport sedan, part of Infiniti's acclaimed G-series lineup. Introduced for the 2011 model year, it was available as a sedan only, serving as a more accessible alternative to the more powerful G37. Key trims included the base G25, G25 Journey, and the all-wheel-drive G25x. With new pricing ranging from approximately $32,000 to $37,000, it stood out for its smooth V6 engine, refined interior, and characteristic Infiniti rear-wheel-drive handling, offering a premium feel without the premium price tag.
The Good
The 2012 Infiniti G25 boasts a smooth 2.5L V6 engine paired with engaging rear-wheel-drive dynamics, appealing to drivers seeking a refined yet sporty experience. Its comfortable, well-appointed interior and elegant design offer a luxurious feel. Practically, it provides better fuel efficiency than its G37 sibling, strong reliability, and excellent used market value, delivering a premium ownership experience at a more accessible price point.
The Bad
While generally robust, the 2012 Infiniti G25's primary weakness for some might be its less potent 2.5L V6 compared to the G37, lacking a "sport" edge. The infotainment system feels dated, and rear legroom is somewhat cramped. Owners should also watch for potential wear on interior trim pieces over time and ensure routine maintenance is strictly followed to prevent common issues.

What Problems Does the 2012 Infiniti G25 Have?
The 2012 Infiniti G25, while generally lauded for its strong build quality and reliability, is not entirely without its potential long-term concerns, many of which are common across the broader Infiniti G-series platform.
One frequently reported issue across the G-series, particularly in hotter climates, is the dashboard material bubbling or cracking over time. While possibly less prevalent on the newer 2012 model due to its age, it's a known aesthetic concern to inspect. Similarly, the soft-touch coating on some interior buttons and trim pieces can become sticky or wear off with age and use, impacting the premium feel of the cabin.
Mechanically, the 2.5-liter VQ25HR engine in the G25 is considered robust. Unlike the G37's VQ37VHR engine, which has known issues with the oil gallery gaskets (a costly repair), the G25's engine does not share this specific vulnerability, contributing to its reputation for mechanical soundness. However, like any vehicle, owners might encounter minor electrical glitches, such as power window motor issues or sensor failures, over extended periods. Some owners also report higher than average brake dust accumulation and potentially earlier wear on brake rotors and pads.
Regarding recalls, the most significant concern affecting the 2012 Infiniti G25 (and many other vehicles of that era) is the widespread Takata airbag recall. Specifically, the passenger front airbag inflator may rupture upon deployment, potentially sending metal fragments into the cabin. Owners of affected G25 models should verify if their vehicle has had this critical recall addressed by checking their VIN with Infiniti or the NHTSA website. It is crucial to have any outstanding recall work completed immediately for safety. Beyond this, specific major mechanical recalls directly targeting the 2012 G25 are less common, suggesting a generally reliable platform when properly maintained.

How long will the 2012 Infiniti G25 last?
With diligent maintenance, the 2012 Infiniti G25 is well-regarded for its long-term durability, often capable of reaching 150,000 to 200,000 miles or more in service years. Many owners report trouble-free ownership well into high mileage, with some examples exceeding 250,000 miles. Key to this longevity is adherence to the maintenance schedule, including regular oil changes, transmission fluid service, and timely replacement of wear-and-tear items.
The 2.5-liter V6 engine and 7-speed automatic transmission are particularly robust. Over time, however, common weaknesses may emerge. These include the eventual wear of suspension components like bushings and struts, which can affect ride quality. Interior elements like dashboard materials or soft-touch button coatings may degrade, especially in extreme climates. Minor electrical issues, such as window motor failures or sensor malfunctions, are also possible but generally not catastrophic. With proper care, the G25 offers impressive long-term reliability.

What Technology & Safety Features are Included?
The 2012 Infiniti G25, while not featuring the cutting-edge autonomous driving tech of today, was well-equipped for its era, offering a solid suite of built-in technology, entertainment, and safety features.
Built-in Tech & Entertainment: Standard amenities included Infiniti's Intelligent Key with push-button ignition, dual-zone automatic climate control, and a rearview monitor, which was a significant convenience feature for the time. The standard audio system was a 6-speaker setup with a CD player, auxiliary audio input jack, and satellite radio capability. Bluetooth phone connectivity was standard, allowing for hands-free calls. For those seeking more, an optional Navigation Package transformed the cabin experience, adding a hard-drive based navigation system with a 7-inch color display, voice recognition, Bluetooth streaming audio, and a 9.3GB Music Box hard drive for digital music storage. A premium Bose audio system was often bundled with this package, providing enhanced sound quality.
Driver-Assistance & Safety: In terms of driver-assistance, the G25 featured the standard rearview camera across all trims and a rear sonar parking system on Journey and G25x models, aiding in parking maneuvers. More advanced systems like adaptive cruise control, blind-spot monitoring, or lane departure warning were not available for this model year.
Safety was a strong point for the G25. It came standard with a comprehensive array of safety features including antilock brakes (ABS) with electronic brakeforce distribution (EBD) and brake assist, vehicle dynamic control (stability control), and traction control. Passive safety measures included front airbags, front seat-mounted side-impact airbags, and roof-mounted curtain airbags for both front and rear outboard occupants, alongside active front head restraints.
Crash-Test Ratings: The 2012 Infiniti G Sedan (of which the G25 is a variant) performed commendably in crash tests. The National Highway Traffic Safety Administration (NHTSA) awarded it an overall 5-star rating, with 5 stars for frontal and side crash protection and 4 stars for rollover resistance. The Insurance Institute for Highway Safety (IIHS) gave the G Sedan "Good" ratings in its moderate overlap front, side, roof strength, and head restraints & seats tests, underscoring its robust safety performance for its class and model year.

2012 Infiniti G25 Prices and Market Value
When new in 2012, the Infiniti G25 had a starting MSRP of approximately $32,000 for the base model, climbing to around $34,000 for the G25 Journey and $35,600 for the G25x AWD, with optional packages adding to the cost. As of 2024, the used market prices for a 2012 G25 typically range from $6,000 to $12,000, reflecting significant depreciation over its twelve-year lifespan.
Infiniti vehicles, similar to many luxury brands, experience substantial depreciation in their early years. However, for a 2012 model, the bulk of this depreciation has already occurred, making it an attractive used car value proposition. Factors critically affecting its current resale value include mileage, overall condition (both mechanical and aesthetic), the completeness of its service history, and the presence of desirable options like the Navigation Package or AWD. A clean title and all outstanding recalls, such as the Takata airbag, being addressed also positively impact its market value.

2012 Infiniti G25 Cost of Ownership
Owning a 2012 Infiniti G25 involves moderate long-term costs. Insurance premiums are generally reasonable for a luxury sport sedan, though slightly higher than economy cars. A notable ongoing expense is fuel; the G25 recommends premium unleaded gasoline, which adds to operating costs despite its decent EPA ratings (20/29 MPG RWD).
Maintenance and repair costs are typical for a luxury brand. While the G25 is reliable, parts and specialized labor can be more expensive than for a non-luxury vehicle, especially if serviced at a dealership. Utilizing reputable independent mechanics can mitigate some of these expenses. Overall, it's not an overtly economical car to own due to premium fuel and luxury-tier parts, but it's certainly not as costly as higher-tier European rivals, striking a balance for a reliable, engaging luxury experience.

How Does the 2012 Infiniti G25 Compare to Other Sedan?
The 2012 Infiniti G25 occupied a competitive space within the entry-level luxury sport sedan segment, stacking up against formidable rivals like the BMW 328i (E90), Mercedes-Benz C250/C300 (W204), Audi A4 2.0T (B8), and the Lexus IS 250.
In terms of performance, the G25's 218-hp 2.5L V6 delivered a notably smooth and linear power delivery, coupled with engaging rear-wheel-drive dynamics. However, it was generally outmatched by the BMW 328i's 230-hp inline-six and the Mercedes C300's 228-hp V6 in outright acceleration. It offered a different character than the Audi A4's turbocharged four-cylinder, which provided more low-end torque but perhaps less refinement. The G25 felt more spirited than the slightly less powerful Lexus IS 250.
Features were competitive; the G25 offered a well-appointed interior with standard leather, dual-zone climate control, and a rearview camera. Its optional navigation and premium audio were on par with rivals, though its infotainment interface might feel less intuitive than some German counterparts.
Reliability is where the G25 often shined. It typically boasted stronger long-term reliability than the BMW 328i and Mercedes C-Class of the same era, which were known for more complex and costly repairs as they aged. It rivaled the legendary dependability of the Lexus IS 250 and Acura TSX/TL, making it a sound choice for buyers prioritizing peace of mind.
From a price perspective, especially in the used market, the G25 often presents a better value than its German rivals, offering similar luxury and driving pleasure for less money. It's usually comparable to or slightly less expensive than the Lexus IS 250 and Acura alternatives.

- Lexus IS 250: A strong "similar" alternative if ultimate reliability and refinement are paramount, though often less engaging to drive.
- BMW 328i (E90): For those prioritizing driving dynamics and willing to accept potentially higher maintenance costs, it's a "better" alternative in terms of pure sportiness.
- Acura TSX/TL: While front-wheel drive, they offer superb reliability and feature content, often at a comparable used price.
Final Verdict: Is the 2012 Infiniti G25 a Good Sedan?
The 2012 Infiniti G25 is an ideal choice for the discerning buyer seeking an accessible entry into the luxury sport sedan segment. It caters wonderfully to individuals who prioritize a smooth, refined V6 engine and engaging rear-wheel-drive dynamics for everyday driving, rather than needing the raw power of its G37 sibling. Its comfortable, well-appointed interior and elegant styling appeal to those desiring a premium experience without the typical luxury price tag.
For these reasons, the 2012 G25 is absolutely worth buying, especially as a used vehicle. Its significant depreciation makes it an excellent value proposition today. Buyers should seek out well-maintained examples, ideally the G25 Journey trim for its enhanced features like a sunroof and heated seats, or the G25x if all-wheel-drive is a necessity. Verifying a complete service history and ensuring any outstanding recalls, particularly the Takata airbag, have been addressed are crucial conditions for a smart purchase, guaranteeing a reliable and enjoyable luxury ownership experience.
