Vehicle History Report

What Problems Does the 2012 Infiniti FX Have?

The 2012 Infiniti FX, like many vehicles, has some reported issues, though overall reliability is generally considered good for its class. One common concern that owners have reported is related to the vehicle's electronic components, particularly the infotainment system. Issues such as screen malfunctions, navigation system glitches, or Bluetooth connectivity problems have been noted. While not specific to the 2012 model year, these can affect later models as well.

Another area to watch out for is the potential for premature wear on suspension components, especially if the vehicle has been driven on rough roads or has high mileage. Some owners have also reported issues with the fuel economy not meeting expectations, though this is more of a characteristic than a defect. On the FX50, the larger V8 engine, while powerful, can be more prone to certain maintenance needs and potentially higher repair costs over time compared to the V6.

Recalls for the 2012 Infiniti FX are relatively few and typically address specific safety concerns that Infiniti has proactively resolved. For instance, there have been recalls related to potential issues with the fuel pump or airbag systems, which are critical safety components. It is always advisable for potential buyers to check the National Highway Traffic Safety Administration (NHTSA) website for any outstanding recalls on a specific vehicle by its VIN.

In terms of long-term reliability, the FX is built on a robust platform. However, like any luxury vehicle, ongoing maintenance is crucial. Neglecting regular oil changes, fluid flushes, and scheduled service can lead to more significant issues down the line. The transmission, in particular, requires proper care. With diligent maintenance, many 2012 Infiniti FX models can continue to provide reliable service for well over 150,000 miles, but it's wise to be prepared for potential repairs on electronic or suspension parts as the vehicle ages.

How long will the 2012 Infiniti FX last?

Based on owner data and typical maintenance patterns, a well-maintained 2012 Infiniti FX can reasonably be expected to last between 150,000 to 200,000 miles, or approximately 10-15 years of service. The FX is known for its durable powertrain, especially the V6 engine in the FX35, which is a strong performer. However, long-term durability can be affected by consistent, high-quality maintenance. Weaknesses that tend to surface over time include potential issues with the electronic systems, such as the infotainment screen or sensors, and possible wear on suspension components, especially if driven in harsh conditions. The FX50's V8, while powerful, may require more intensive maintenance and potentially costlier repairs as it ages compared to its V6 counterpart. Regular fluid changes, timely brake replacements, and attention to any warning lights are crucial for maximizing its lifespan.

What Technology & Safety Features are Included?

The 2012 Infiniti FX offered a commendable suite of technology, entertainment, and safety features for its era, blending convenience with a focus on the driver's experience. Standard entertainment features often included an 8-speaker Bose audio system, an in-dash 7-inch color display, and Bluetooth hands-free phone connectivity. Many models also came equipped with a standard rearview camera, aiding in parking and maneuvering.

Moving up the trim levels or opting for packages unlocked more advanced technology. The available navigation system, powered by a hard drive and featuring voice recognition, was a significant upgrade for many buyers. Satellite radio was also a common option. For those seeking a more premium audio experience, a Bose premium sound system was often part of higher trims or optional packages.

Driver-assistance features were also present, particularly on higher trims or with optional packages. Adaptive cruise control was a notable option, capable of maintaining a set distance from the vehicle ahead. Some models could also be equipped with lane departure warning (LDW) and lane departure prevention (LDP) systems, which helped alert the driver and subtly guide the vehicle back into its lane if drifting.

In terms of safety, the 2012 Infiniti FX was designed with occupant protection in mind. Standard safety features typically included front-seat airbags, front-seat side-impact airbags, and roof-mounted side-curtain airbags for both rows. Anti-lock brakes (ABS), traction control, and stability control were also standard. Crash-test ratings from organizations like the NHTSA and IIHS generally indicated good performance, with the FX often receiving high marks in frontal and side-impact crash tests. For instance, the NHTSA typically awarded it 4 out of 5 stars in various categories. Optional safety features could include forward collision warning and intelligent brake assist.

Overall, the 2012 FX provided a solid foundation of modern tech and safety, with generous options for those who wanted the latest advancements available at the time.

2012 Infiniti FX Prices and Market Value

When new, the 2012 Infiniti FX had a starting Manufacturer's Suggested Retail Price (MSRP) that typically ranged from approximately $44,000 for the base FX35 RWD to over $60,000 for the well-equipped FX50 AWD model. Currently, the used market prices for a 2012 Infiniti FX vary significantly based on mileage, condition, trim level, and location, but generally fall between $10,000 and $20,000. The FX has experienced a notable depreciation from its original price, which is typical for luxury vehicles. Factors affecting its resale value include its sporty performance appeal, luxury interior, and Infiniti's reputation for build quality. However, higher mileage, less desirable color combinations, or a history of poor maintenance can negatively impact its value. The FX35 trims tend to hold their value slightly better than the FX50 due to their more balanced fuel economy and lower initial purchase price.

2012 Infiniti FX Cost of Ownership

Owning a 2012 Infiniti FX is generally considered moderately costly, leaning towards the expensive side compared to non-luxury SUVs. Insurance premiums can be higher due to its luxury status and performance capabilities. Fuel costs are a significant factor, especially for the FX50, given its V8 engine and less efficient fuel economy. Maintenance costs are typical for a luxury brand, with routine services like oil changes and tire rotations being standard, but specialized repairs or parts can be pricier than for mainstream vehicles. Repair costs can also be elevated if major components, particularly electronics or the V8 engine, require attention. Overall, it is not an economical vehicle to own, requiring a budget that accounts for premium fuel, potentially higher insurance, and the likelihood of more expensive maintenance and repairs over its lifespan.

How Does the 2012 Infiniti FX Compare to Other Vehicle?

The 2012 Infiniti FX competed in a segment with strong rivals like the BMW X5, Mercedes-Benz ML-Class, Lexus RX, and Acura MDX. In terms of performance, the FX, particularly the FX50 with its V8, often outperformed competitors with its raw power and sporty handling. The FX35 offered a good balance of performance and efficiency.

Regarding features, the FX was well-equipped for its price point, often offering premium materials and a generous standard feature list. However, some rivals like the BMW X5 might have offered more advanced technology options or a slightly more refined interior at a similar price. The Lexus RX was known for its unparalleled comfort and quiet ride, while the MDX offered excellent value with its standard all-wheel drive and three-row seating.

Reliability is a mixed bag. While Infiniti generally has a good reputation, the FX had some reported electronic glitches and a thirstier fuel consumption than some competitors, particularly the RX and MDX. The German rivals, X5 and ML-Class, could sometimes present higher maintenance and repair costs over the long term.

On the price front, the FX often offered a compelling value proposition, providing a potent blend of luxury and performance for less than similarly equipped German counterparts. However, it was typically priced higher than the Lexus RX and Acura MDX, which often came with more practicality.

Alternatives:
  • For more practicality and seating: The Acura MDX offers a more spacious interior with an optional third row and standard AWD, making it a strong family-oriented choice.
  • For ultimate luxury and comfort: The Lexus RX provides a smoother ride, exceptional reliability, and a serene cabin, though with less sporty dynamics.
  • For driving dynamics and prestige: The BMW X5 is a benchmark for sporty handling in its class, offering a more engaging driving experience but at a potentially higher cost of ownership.
  • For robust German engineering: The Mercedes-Benz ML-Class offers a luxurious and comfortable ride with strong build quality, though it can be more expensive to maintain.
While the 2012 Infiniti FX stands out with its aggressive styling and potent performance, buyers prioritizing practicality or absolute long-term reliability might find the MDX or RX more suitable. Those seeking a more engaging driving experience might lean towards the X5, understanding the associated costs.

Final Verdict: Is the 2012 Infiniti FX a Good Vehicle?

The 2012 Infiniti FX is ideal for buyers who prioritize bold styling and engaging performance in a luxury crossover. It's for those who appreciate a sporty driving experience and a premium interior, and are less concerned with maximum cargo space or the absolute best fuel economy. It is definitely worth considering on the used market for individuals seeking a stylish and powerful vehicle at a more accessible price than when new.

Buying used is the most sensible approach now. The FX35 trim, with its robust V6, offers a better balance of performance and running costs compared to the V8-powered FX50. Thorough pre-purchase inspection, especially checking for electrical issues and suspension wear, is crucial. If you value a unique, driver-focused luxury SUV and are prepared for moderate ownership costs, the 2012 Infiniti FX can be a rewarding purchase.
