What Problems Does the 2015 Infiniti Q50 Have?
For the 2015 Infiniti Q50, several issues have been frequently reported by owners. The most prominent is related to the Direct Adaptive Steering (DAS) system. While innovative, some drivers found it lacked road feel, and early models, particularly the 2014 and 2015 Q50, were susceptible to glitches or inconsistent steering behavior, sometimes requiring software updates or even replacement. This steer-by-wire system was a key source of concern.
Another common complaint targets the Infiniti InTouch dual-screen infotainment system. Users often report slow response times, freezing, Bluetooth connectivity issues, and a generally unintuitive interface. Despite some software patches, it remains a frequent point of frustration.
Less common, but reported, are instances of transmission issues, such as rough shifting or hesitation from the 7-speed automatic transmission, often attributed to software calibration rather than mechanical failure.
Hybrid models have occasionally seen reports of premature 12V battery drain, leading to starting problems. Over time, some owners also note minor suspension noises like squeaks or creaks.
Several important recalls have been issued for the 2015 Q50:

Hybrid models have occasionally seen reports of premature 12V battery drain, leading to starting problems. Over time, some owners also note minor suspension noises like squeaks or creaks.
Several important recalls have been issued for the 2015 Q50:
- NHTSA Campaign Number: 14V674000 (Engine Control Module Reprogramming): Addressed potential engine stalling due to incorrect ECM programming under specific conditions, affecting both 2014-2015 Q50 and Q50 Hybrid.
- NHTSA Campaign Number: 14V375000 (Steering Control Unit Reprogramming): Crucial for models with DAS, this recall addressed the risk of sudden loss of steering control due to a fault in the system's backup mechanism, applicable to 2014-2015 Q50 and Q50 Hybrid.
- NHTSA Campaign Number: 15V001000 (Fuel Pump Control Module): Incorrect programming could cause the fuel pump to cease operation, leading to engine stall, affecting 2014-2015 Q50 and Q50 Hybrid.
How long will the 2015 Infiniti Q50 last?
With proper, diligent maintenance, the 2015 Infiniti Q50 is a durable vehicle capable of reaching 150,000 to 200,000 miles, potentially more, over 10-15 years of service. Its core components, particularly the VQ37VHR V6 engine and 7-speed automatic transmission, are robust and known for longevity when well-cared for.
Long-term durability is a strong point for the powertrain. However, weaknesses tend to emerge in the advanced electronic systems. The Direct Adaptive Steering (DAS) and the dual-screen infotainment system are prone to costly repairs or glitches as the vehicle ages. Suspension components like bushings and struts will naturally wear over time. Hybrid models may eventually face battery degradation, although often covered by extended warranties. Regular maintenance, including fluid changes and addressing recalls promptly, is paramount to maximizing its lifespan and minimizing unexpected repairs.

2015 Infiniti Q50 Prices and Market Value
When new, the 2015 Infiniti Q50 had an MSRP ranging from approximately $37,000 for the base 3.7 RWD model to over $49,000 for fully optioned Sport or Hybrid AWD trims. Fully loaded models could easily exceed $50,000.
On the current used market (mid-2024), prices for a 2015 Q50 typically range from $10,000 to $18,000, depending heavily on condition, mileage, and specific trim. Entry-level 3.7 models are found at the lower end, while well-maintained Hybrid or Sport models fetch higher prices.
The Q50, like most luxury sedans, experiences significant depreciation. It loses a substantial portion of its value in the first few years, often 50-60% within five years, making it an attractive used car value. Factors affecting resale value include mileage, overall condition, documented service history, the presence of desirable packages (e.g., Technology Package), and whether it has the controversial Direct Adaptive Steering (some buyers prefer traditional steering).

How Does the 2015 Infiniti Q50 Compare to Other Sedan?
The 2015 Infiniti Q50 competes in a fiercely competitive segment against rivals like the BMW 3-Series (F30), Mercedes-Benz C-Class (W205), Audi A4 (B8.5), Lexus IS (XE30), and Cadillac ATS.
In terms of Performance, the Q50's naturally aspirated 3.7L V6 delivers a potent 328 hp, often outclassing base and mid-level turbocharged rivals like the BMW 328i or Audi A4 in raw power. The Hybrid model, with 360 combined hp, is a performance standout. However, its optional Direct Adaptive Steering (DAS) often lacks the communicative feedback found in a BMW 3-Series or Cadillac ATS, which are renowned for superior driving dynamics.
Regarding Features, the Q50's dual-screen Infiniti InTouch infotainment system was innovative but widely criticized for being clunky and slow compared to BMW's iDrive, Mercedes' COMAND, or Audi's MMI, which offered more refined user experiences. The Q50 did offer a comprehensive suite of advanced driver-assistance features for its era.
Reliability of the Q50's core mechanicals (engine, transmission) is generally strong, inherited from Nissan's robust VQ family. However, issues tend to arise from its advanced electronics, specifically the DAS and infotainment. The Lexus IS typically holds the crown for reliability in this class, while European rivals like BMW and Mercedes, though improved, can still incur higher long-term repair costs.
Price-wise, the Q50 was competitively priced new, offering significant power and features for the money. On the used market, it suffers more depreciation than its German and Japanese rivals (except perhaps Cadillac ATS), making it an excellent value proposition for used luxury buyers. Lexus IS models generally hold their value best.
