The 2015 Infiniti QX70, formerly known as the FX series, is a distinctive mid-size luxury crossover SUV. It's celebrated for its unique, coupe-like body style that offers an athletic stance. Model years under the QX70 badge spanned from 2014 to 2017. Key trims for 2015 included the standard QX70 and the AWD variant, both primarily featuring a V6 engine. New prices ranged from approximately $45,000 to $50,000. Its bold design and sports-car-like handling make it stand out from typical SUVs.
The Good
The 2015 Infiniti QX70 offers a compelling blend of advantages. Its powerful V6 engine and sporty handling provide an emotionally engaging driving experience. The striking, aggressive design appeals to those seeking a unique aesthetic. Practically, it boasts a well-appointed, comfortable cabin with quality materials and generally strong reliability. Used, it represents excellent value for a luxury performance SUV, balancing a thrilling ride with everyday usability.
The Bad
Known weaknesses of the 2015 Infiniti QX70 include its relatively cramped rear passenger space and limited cargo capacity compared to more traditional SUVs. The aggressive styling compromises rear visibility. Some find the sporty suspension delivers a firm ride, which might not suit everyone's comfort preferences. Its infotainment system can also feel a bit dated, and fuel efficiency is not class-leading.

What Problems Does the 2015 Infiniti QX70 Have?
The 2015 Infiniti QX70, while generally known for its robust build and solid performance, does have some frequently reported problems and long-term reliability concerns that potential buyers should be aware of. While Infiniti typically ranks well for reliability, certain areas warrant attention for this specific model.
- Infotainment and Electrical Glitches: Owners occasionally report issues with the infotainment system, including navigation functionality feeling dated, occasional Bluetooth connectivity problems, and general user interface sluggishness. While not critical, these can detract from the luxury experience over time.
- Suspension Component Wear: Due to its sporty tuning and heavier curb weight, components like control arm bushings and shock absorbers can experience accelerated wear, particularly on models frequently driven on rough roads or those equipped with larger 20-inch and 21-inch wheels. This can manifest as clunking noises over bumps or a noticeable degradation in ride quality.
- Brake Wear: The QX70's powerful engine and weight contribute to faster-than-average wear on brake pads and rotors. Regular inspection and replacement are often required, leading to higher maintenance costs in this area.
- Power Steering Leaks: Some owners have reported issues with the power steering system, including leaks from hoses or the pump itself, especially as the vehicle ages. This can lead to a loss of power assist and requires professional repair.
- Water Leaks: Clogged sunroof drains are a common culprit for water intrusion into the cabin. Additionally, deterioration of seals around the rear hatch can sometimes lead to water entering the cargo area, requiring inspection and sealing.
- Catalytic Converters: While less common, catalytic converter failure has been reported in some higher-mileage examples, which can be an expensive repair and trigger "Check Engine" lights.
How long will the 2015 Infiniti QX70 last?
With diligent maintenance and responsible ownership, a 2015 Infiniti QX70 can typically achieve an average lifespan of 150,000 to 200,000 miles, and potentially even more. This translates to 10 to 15 years of reliable service. The 3.7-liter V6 engine and the automatic transmission are generally considered robust and durable components that hold up well over time when serviced correctly. Factors like consistent oil changes, scheduled fluid flushes, and prompt attention to warning lights significantly contribute to its longevity. However, over time, common weaknesses can emerge. Owners might expect to replace suspension components like bushings and shocks due to normal wear and tear, especially if the vehicle frequently encounters rough roads. The power steering system can develop leaks, and electrical components or the aging infotainment system may become less reliable or outdated. Despite these potential areas, the QX70 generally offers good long-term durability for its core mechanicals.
What Technology & Safety Features are Included?
The 2015 Infiniti QX70, while preceding the latest wave of automotive technology, offered a respectable suite of built-in tech, entertainment, driver-assistance, and safety features for its time.
- Built-in Tech & Entertainment: Standard features included a 7-inch color display for the infotainment system, a convenient rearview camera, dual-zone automatic climate control, keyless ignition and entry, and Bluetooth hands-free phone connectivity. Entertainment was provided by an 11-speaker Bose audio system, complete with a CD player, satellite radio capability, and a USB input. Optional enhancements, often bundled in packages, included an 8-inch touchscreen interface, a navigation system with voice recognition, Bluetooth audio streaming, and Infiniti's highly regarded Around View Monitor (360-degree parking camera system) along with front and rear parking sensors.
- Driver-Assistance Features: For advanced driver assistance, the optional Technology Package was comprehensive. It added adaptive cruise control, which could maintain a set distance from the vehicle ahead, a forward collision warning system, and automatic emergency braking to mitigate potential impacts. Lane departure warning and prevention systems helped keep the vehicle in its lane, while adaptive headlights and automatic wipers contributed to safer driving in varying conditions.
- Safety Features: Standard safety equipment across all QX70 models included antilock brakes (ABS), stability control, traction control, front-seat side airbags, full-length side curtain airbags, and active front head restraints to reduce whiplash injuries. The rearview camera was also standard, aiding in safer reversing.
- NHTSA (National Highway Traffic Safety Administration): The 2015 Infiniti QX70 received strong individual crash test ratings but was not assigned an overall safety rating. It earned 4 out of 5 stars for the frontal crash test (driver side), 5 stars for the frontal crash test (passenger side), a full 5 stars for the side crash test, and 4 stars for the rollover resistance test.
- IIHS (Insurance Institute for Highway Safety): The QX70 generally performed well in IIHS testing, receiving "Good" ratings in key categories such as the moderate overlap front, side impact, roof strength, and head restraints & seats tests. The small overlap front test, a more stringent assessment, was not specifically rated for the 2015 model year.

2015 Infiniti QX70 Prices and Market Value
When new, the 2015 Infiniti QX70 had a starting MSRP of approximately $45,000 for the base RWD V6 model, with well-equipped AWD variants and optional packages pushing prices into the $55,000 to $60,000+ range.
Today, in the used market, prices for a 2015 QX70 vary significantly. Buyers can expect to find models ranging from roughly $10,000 to $15,000 for higher mileage or fair condition vehicles, while well-maintained, lower-mileage examples with desirable packages often command $18,000 to $25,000 or even higher depending on location and demand.
Depreciation for the QX70 has been substantial, typical for luxury vehicles once they leave the showroom, making it a compelling used purchase. This depreciation is influenced by several factors: its age, the general softening of demand for older luxury SUVs with less fuel-efficient engines, and the continuous advancement of automotive technology. Factors that positively affect resale value include lower mileage, a clean title, a comprehensive service history, and the presence of desirable optional packages like the Technology or Deluxe Touring packages, and the more popular AWD configuration.
2015 Infiniti QX70 Cost of Ownership
Long-term ownership of a 2015 Infiniti QX70 can be considered more costly than an average non-luxury vehicle. Insurance premiums tend to be higher due to its luxury classification, performance capabilities, and the cost of replacement parts. Fuel costs are also significant; the 3.7L V6 engine typically requires premium gasoline and delivers moderate fuel economy, averaging around 16-17 MPG in mixed driving.
Maintenance costs are elevated compared to mainstream brands. While routine services are manageable, specialized Infiniti parts and higher labor rates at dealerships or luxury-focused independent shops mean you should budget more. Repairs, particularly for suspension components, brakes, or any electrical issues, can be expensive. Overall, while the QX70 offers a luxurious and engaging driving experience, it is not an economical vehicle to own in the long run, demanding a higher budget for ongoing expenses.

How Does the 2015 Infiniti QX70 Compare to Other Sport Utility Vehicle?
The 2015 Infiniti QX70 occupies a unique space within the luxury mid-size SUV segment, often stacked against rivals like the BMW X5, Mercedes-Benz M-Class (GLE), Porsche Cayenne, Acura MDX, and Lexus RX.
- Performance: The QX70 truly stands out here with its standard 325-hp 3.7L V6, offering an engaging, sports-car-like driving experience with firm steering and a taut suspension. It feels more athletic than the comfort-oriented Lexus RX or Acura MDX. While it might not match the outright power or handling prowess of the high-performance variants of the BMW X5 or Porsche Cayenne, especially their V8 offerings, the QX70 delivers a unique "driver's SUV" feel at a more accessible price point. Its responsiveness and handling are arguably its strongest suit against most competitors.
- Features: The QX70 comes well-equipped for its price, offering standard leather upholstery, an 11-speaker Bose audio system, and a rearview camera. However, its infotainment system, while functional, generally feels less sophisticated and more dated compared to the iDrive in the BMW X5 or COMAND in the Mercedes-Benz M-Class. Rivals also often offered more cutting-edge driver-assistance technologies as standard or more advanced options. The QX70's Around View Monitor was a standout feature for its time.
- Reliability: Infiniti generally has a solid reputation for reliability, placing the QX70 ahead of many European competitors like BMW, Mercedes, and Porsche, which can be prone to more complex and expensive long-term issues. However, it typically trails the class-leading reliability of the Lexus RX and Acura MDX. Common concerns include suspension component wear and aging infotainment systems.
- Price: When new, the QX70 was competitively priced. In the used market, it represents significant value. It depreciates more rapidly than Lexus or Acura models, making it much more affordable used than comparable BMW X5s, Mercedes GLEs, or Porsche Cayennes of the same vintage, which often carry a premium even after depreciation, along with higher ownership costs.
- Similar Performance/Style: For a similar "coupe-SUV" aesthetic and performance focus, the BMW X6 is a direct rival, albeit often more expensive to buy and maintain. Older Porsche Cayenne models can also offer comparable driving dynamics.
- Better Reliability/Value: For buyers prioritizing rock-solid reliability, lower running costs, and more family-friendly practicality, the Acura MDX or Lexus RX are superior alternatives.
- More Modern Tech/Luxury: If budget allows, newer generations of the BMW X5, Mercedes-Benz GLE, or Audi Q5/Q7 offer more advanced technology and contemporary luxury, though at a higher price point.
Final Verdict: Is the 2015 Infiniti QX70 a Good Sport Utility Vehicle?
The 2015 Infiniti QX70 is an ideal vehicle for buyers who prioritize distinctive, aggressive styling, an engaging and sporty driving experience, and a luxurious cabin, often over maximum practicality or the latest technology. It's particularly well-suited for individuals or couples seeking a "sports car on stilts" feel in an SUV body, rather than large families needing extensive cargo or rear passenger space.
As a used vehicle, the 2015 QX70 is absolutely worth buying. Its significant depreciation makes it an excellent value proposition, offering a premium luxury-performance experience for a fraction of its original cost. Look for models with the Premium or Deluxe Touring packages for a more refined interior and desirable tech features, or the Sport Package if performance is paramount. AWD variants are generally more versatile. Key conditions for purchase include seeking out examples with a complete and documented service history, performing a thorough pre-purchase inspection focusing on suspension and power steering components, and being prepared for higher-than-average running costs due to premium fuel requirements and luxury-level maintenance/repair expenses. It's not for the highly budget-conscious or those demanding cutting-edge infotainment.
