What Problems Does the 2015 Infiniti Q40 Have?
The 2015 Infiniti Q40, inheriting much from the G37 sedan, generally boasts a strong reputation for reliability. However, as with any vehicle, some common issues have been reported by owners over time. One of the more frequently cited concerns relates to the infotainment system, which can feel dated by modern standards and may occasionally experience glitches such as unresponsiveness or Bluetooth connectivity issues. While not a widespread problem, some owners have reported minor electrical issues, including problems with power windows or door locks.
Another area where some owners have noted concerns is the suspension. Over time, particularly on higher-mileage vehicles, components like shocks and struts may need replacement, leading to a less refined ride or potential noises. Brake wear can also be a factor, especially with spirited driving.
Regarding recalls, the 2015 Infiniti Q40 had a few, primarily related to potential issues with the occupant classification system (OCS) sensor, which could prevent the passenger airbag from deploying in a crash. Other recalls have addressed potential fuel leaks or issues with the airbag control unit. It's crucial for prospective buyers to check the VIN against recall databases to ensure any outstanding recalls have been addressed.
In terms of long-term reliability, the 3.7-liter V6 engine is generally considered robust and capable of reaching high mileage with proper maintenance. The 7-speed automatic transmission is also usually dependable. However, like many luxury vehicles, maintenance costs can be higher than average, and neglecting regular service can lead to accelerated wear on various components. Early models of the G37 sedan (which the Q40 is based on) sometimes saw issues with the power steering system, though this seems less prevalent on later iterations like the 2015 Q40.

How long will the 2015 Infiniti Q40 last?
Based on owner data and typical maintenance habits, the 2015 Infiniti Q40 is a vehicle designed for longevity. With consistent oil changes, fluid checks, and timely replacement of wear items like brakes and tires, it's not uncommon for Q40 models to comfortably exceed 150,000 miles, with many reaching 200,000 miles or more. The core powertrain, the 3.7-liter V6 engine and 7-speed automatic transmission, are known for their durability. Weaknesses that tend to emerge over time, usually after 100,000 miles, include potential suspension component wear (shocks, struts, bushings) and possible minor electrical gremlins. The infotainment system may also show its age in terms of responsiveness and features. Overall, with diligent care, the Q40 demonstrates strong long-term durability.
What Technology & Safety Features are Included?
The 2015 Infiniti Q40 offers a respectable suite of technology, entertainment, and safety features for its era, though it predates many of the advanced driver-assistance systems common in newer vehicles. Standard technology includes a 7-inch color display that serves as the interface for the infotainment system. This system features a six-speaker audio system, an AM/FM/CD/DVD player, USB and auxiliary audio inputs, and Bluetooth connectivity for hands-free calling and audio streaming. Infiniti Connection services were also available, providing remote access to vehicle features and services.
In terms of driver assistance, the 2015 Q40 is quite basic by today's standards. It lacks modern features like adaptive cruise control, lane departure warning, or blind-spot monitoring. Standard safety equipment is robust, however. It comes equipped with anti-lock brakes (ABS) with electronic brake-force distribution (EBD) and brake assist. For vehicle control, it includes standard traction control and stability control systems. Airbag protection is comprehensive, featuring front-seat side-impact airbags, full-length side curtain airbags, and front-seat active head restraints designed to reduce whiplash injuries in a rear collision.
Optional features could enhance the experience, often bundled in packages. These might include a premium Bose audio system for superior sound quality, a navigation system with a larger screen and voice recognition, a rearview camera for easier parking, and front and rear parking sensors. Some models might also offer a sport-tuned suspension for more engaging handling.
Crash-test ratings for the 2015 Infiniti Q40, based on its G37 sedan underpinnings, are generally positive. The National Highway Traffic Safety Administration (NHTSA) awarded it an overall 4-star safety rating. In specific tests, it received 4 stars for frontal-barrier crash tests (driver and passenger) and 5 stars for side-impact crash tests (front and rear passenger). The Insurance Institute for Highway Safety (IIHS) rated it as "Good" in moderate overlap front, side impact, roof strength, and head restraint/seat crash tests, earning it a Top Safety Pick designation for its model year.

2015 Infiniti Q40 Prices and Market Value
When new, the 2015 Infiniti Q40 had a Manufacturer's Suggested Retail Price (MSRP) starting around $34,450 for the rear-wheel-drive model and a bit more for the all-wheel-drive version. Today, the used market for a 2015 Infiniti Q40 typically ranges from approximately $9,000 to $16,000, depending heavily on mileage, condition, trim level, and optional features. The Q40 has experienced significant depreciation from its original MSRP, which is common for luxury sedans. Factors affecting its resale value include its reputation for reliability, its sporty V6 engine, and its relatively well-appointed interior. Conversely, its aging infotainment system, less competitive fuel economy compared to newer rivals, and the availability of more modern luxury sedans in the used market can dampen its resale appeal. Well-maintained examples with lower mileage will always command higher prices.
2015 Infiniti Q40 Cost of Ownership
Owning a 2015 Infiniti Q40 involves moderate to slightly higher-than-average ownership costs. Insurance premiums are generally comparable to other luxury sedans in its class, though this varies by driver profile and location. Fuel costs are a notable factor due to its less-than-stellar EPA ratings from the V6 engine; expect to spend more on gasoline than for a smaller, more efficient car. Maintenance costs for Infiniti vehicles tend to be higher than mainstream brands, with routine services like oil changes, tire rotations, and brake replacements costing more. Repair costs for specialized parts or complex issues can also be significant. While the Q40 offers good value and reliability, it's not the most economical choice for long-term ownership, leaning towards costly rather than economical.

How Does the 2015 Infiniti Q40 Compare to Other Sedan?
The 2015 Infiniti Q40 competed in a crowded segment of compact luxury sedans. Against rivals like the BMW 3 Series, it offered a more potent V6 engine for the price, delivering superior horsepower and acceleration. However, the BMW often provided a more engaging driving experience, sharper handling, and a more advanced technology suite. For buyers prioritizing outright performance and a powerful V6, the Q40 was a compelling option, often at a lower price point than a similarly equipped 3 Series.
Compared to the Audi A4, the Q40 again leaned towards raw power over refinement and cutting-edge tech. The A4 typically boasted a more sophisticated interior, a sleeker design, and available Quattro all-wheel-drive known for its excellent traction. The Q40's infotainment system was also significantly less advanced than Audi's MMI. Price-wise, the Q40 was generally more affordable, making it a value-oriented performance choice.
The Mercedes-Benz C-Class offered a more luxurious and comfort-oriented experience, with a higher perceived quality of materials and a smoother ride. While its performance might not have matched the Q40's V6 punch (especially with base engines), the C-Class aimed for a more refined luxury feel. The Q40's reliability reputation was often considered on par with, or better than, its German counterparts, especially when looking at long-term ownership costs.

Alternatives:
- Acura TLX: For a similar price point, the TLX offered available V6 power and a more modern interior with updated technology. It aimed for a blend of sport and comfort, though some found its handling less engaging than the Q40.
- Lexus IS 350: This is a very strong competitor, offering a potent V6, excellent reliability, and a well-built interior. The IS 350 often provides a more refined driving experience and superior interior materials, though it might come at a slightly higher price on the used market.
- Infiniti Q50 (later model years): If the Q40's aging tech is a concern, looking at a slightly used Q50 (which replaced the G37/Q40 sedan) would offer a more modern infotainment system, updated styling, and potentially more driver-assistance features, though often at a higher price.
Final Verdict: Is the 2015 Infiniti Q40 a Good Sedan?
The 2015 Infiniti Q40 is ideal for buyers seeking strong V6 performance and a luxurious feel without the premium price tag of some German rivals. It's a great choice for those who prioritize an engaging driving experience and a reliable powertrain over the latest in infotainment technology. It's worth buying, especially on the used market, as it represents excellent value for a performance-oriented luxury sedan. Look for well-maintained examples, ideally with lower mileage, and consider the AWD version if you live in an area with inclement weather. It is definitely best considered as a used car purchase, as its value proposition is strongest in this segment. Avoid it if advanced tech features and cutting-edge connectivity are high on your priority list.
