Detailed Explanations

2016-2017 (First Generation, J50)

  • 3.7L V6 Engine: The first-generation QX50 (then called the EX37) featured a robust 3.7-liter V6 engine, known for its smooth power delivery and reliability. This engine offers ample horsepower for confident acceleration and enjoyable driving dynamics.

  • Rear-Wheel Drive (Standard) / All-Wheel Drive (Optional): The standard rear-wheel-drive configuration provides a more engaging driving experience, while the optional all-wheel-drive system enhances traction and stability in various weather conditions.

  • Comfortable Ride and Spacious Interior: The first-generation QX50 is praised for its comfortable ride quality and surprisingly spacious interior, especially for a compact SUV of its time. The seats are supportive, and the cabin offers ample headroom and legroom for both front and rear passengers.

  • Dated Infotainment System: One of the main drawbacks of the 2016-2017 models is the dated infotainment system. It lacks modern features like Apple CarPlay and Android Auto, and the graphics and interface can feel clunky compared to newer systems.

  • Lower Fuel Economy: The 3.7L V6 engine, while powerful, is not particularly fuel-efficient. Expect lower gas mileage compared to the later models with the 2.0L VC-Turbo engine.

  • Suspension Issues: Some owners have reported issues with the suspension components, particularly the shocks and struts, requiring replacement sooner than expected. This is something to be aware of when considering a used model.

2019-2021 (Second Generation, T32)

  • 2.0L VC-Turbo Engine: The second-generation QX50 introduced the groundbreaking 2.0-liter VC-Turbo (Variable Compression Turbo) engine. This engine is designed to automatically adjust its compression ratio to optimize for either power or fuel efficiency. It's a technologically advanced engine but has faced some reliability challenges.

  • Front-Wheel Drive (Standard) / All-Wheel Drive (Optional): The second-generation QX50 shifted to a front-wheel-drive platform as standard, with all-wheel drive available as an option. This change was aimed at improving fuel efficiency.

  • Innovative Variable Compression Engine: The VC-Turbo engine is a significant innovation, promising both strong performance and good fuel economy. However, its complex design has led to concerns about long-term reliability.

  • Updated Infotainment System: The second-generation models received an updated infotainment system, but it has been criticized for its slow response times, unintuitive interface, and tendency to glitch.

  • VC-Turbo Engine Reliability Concerns: The primary concern with the 2019-2021 QX50 models is the reliability of the VC-Turbo engine. Some owners have reported issues with the engine's sensors, turbocharger, and overall performance. It's essential to have a thorough inspection performed by a qualified mechanic before purchasing one of these models.

  • Complex Engine Design: The complexity of the VC-Turbo engine means that repairs can be more expensive and time-consuming compared to simpler engines.

  • CVT Transmission Performance: The QX50 uses a continuously variable transmission (CVT), which some drivers find less engaging than a traditional automatic transmission. Some have complained about a rubber-band feel and a lack of responsiveness.

2022-2024 (Second Generation, T32 - Refreshed)

  • 2.0L VC-Turbo Engine (Improvements Made): Infiniti has made improvements to the VC-Turbo engine in the 2022-2024 models, addressing some of the reliability concerns that plagued earlier versions. While the engine is still complex, the updates aim to improve its longevity and performance.

  • Enhanced Safety Features: The 2022-2024 QX50 models come with a more comprehensive suite of standard safety features, including advanced driver-assistance systems (ADAS) like lane departure warning, blind-spot monitoring, and automatic emergency braking.

  • Improved Interior Materials and Design: Infiniti has upgraded the interior materials and design in the refreshed QX50, creating a more luxurious and refined cabin environment.

  • Refined Driving Experience: The 2022-2024 models offer a slightly refined driving experience compared to the earlier second-generation models, with improvements to the suspension and steering.

  • Continued VC-Turbo Engine Reliability Concerns (Though Improved): While improvements have been made, the VC-Turbo engine still carries some reliability risk. It's advisable to research the specific issues reported for the model year you're considering and ensure the vehicle has a comprehensive service history.

  • Infotainment System Bugs Still Present: Although some updates have been implemented, the infotainment system can still be prone to glitches and slow response times.

  • CVT Transmission Performance (Similar to Earlier Models): The CVT transmission remains in use, and some drivers may still find its performance less than ideal.
