Infiniti Q50: A Comprehensive Buyer's Guide

The Infiniti Q50 is a luxury sport sedan that has been a staple in Infiniti's lineup since its introduction. Positioned as a competitor to the BMW 3 Series, Audi A4, and Mercedes-Benz C-Class, the Q50 aims to blend performance, technology, and distinctive styling at a competitive price point. This guide will provide a detailed overview of the Q50, covering its history, generations, reliability, driving experience, and offering advice for prospective buyers.

Generations

First Generation (2014 - Present)

The Q50 marked a significant departure from its predecessor, the G37 sedan, with a new design language, updated technology, and a refreshed lineup of engines. While officially still in production, this generation has received numerous updates and facelifts over the years.

  • 2014: Introduction of the Q50, featuring a redesigned exterior and interior. Key features include the InTouch dual-screen infotainment system and available Direct Adaptive Steering (DAS). Engine options included a 3.7L V6 and a hybrid powertrain.
  • 2016: Introduction of the 2.0t turbocharged four-cylinder engine as a more fuel-efficient option.
  • 2017: Major refresh with revised front and rear fascias. The introduction of the VR-series 3.0t twin-turbo V6 engine in varying power outputs (300 hp and 400 hp "Red Sport 400"). Significant updates to the steering and suspension systems.
  • 2018: Minor trim and feature adjustments.
  • 2019: Apple CarPlay and Android Auto became standard on all models.
  • 2020: Further refinement of trim levels and available features.
  • 2023: Discontinuation of the base 2.0t engine.

Reliability & Common Issues

The Infiniti Q50, while generally considered a reliable vehicle, has its share of common issues. Understanding these potential problems can help you make an informed purchase decision.

Engine Issues:

  • 3.7L VQ37VHR (2014-2015): Known for its robust performance, the VQ37VHR engine can suffer from oil consumption issues, particularly in earlier model years. Regular monitoring of oil levels is crucial. Valve cover gaskets can also leak.
  • 2.0t Turbocharged Four-Cylinder: While relatively reliable, turbocharger issues and oil leaks are possible. Ensure proper maintenance and regular oil changes.
  • 3.0t VR30DDTT (2017-Present): This engine, especially the 400 hp version, has been reported to have issues with heat management, leading to potential oil degradation and turbocharger problems. Early VR30 engines (2017-2018) are more prone to turbo failures. The auxiliary belt tensioner can also fail. Catch cans are recommended by many owners.
  • Hybrid Powertrain: Battery life and the complexity of the hybrid system can lead to potential repairs over time. Check for any error codes related to the hybrid system before purchasing.

Transmission Issues:

  • The 7-speed automatic transmission is generally reliable, but some owners have reported rough shifting or occasional hesitation. Regular transmission fluid changes are essential for longevity.

Electrical & Technology Issues:

  • InTouch System: The dual-screen infotainment system has been criticized for its slow response times and outdated interface. Software updates can sometimes improve performance, but the system's limitations are inherent.
  • Direct Adaptive Steering (DAS): While offering a unique steering feel, DAS has been known to experience occasional glitches and requires specialized maintenance. Some drivers find the artificial steering feel disconcerting, while others appreciate its precision.
  • Sensor Issues: Adaptive cruise control, blind-spot monitoring, and other driver-assistance systems can sometimes experience sensor malfunctions, requiring recalibration or replacement.

Suspension & Steering Issues:

  • Front lower control arm bushings are a common wear item.
  • Steering rack problems have been reported, particularly on models equipped with DAS.

Driving Experience

The Infiniti Q50 offers a range of driving experiences depending on the engine and options chosen.

Pros:

  • Powerful Engine Options: The 3.0t twin-turbo V6, especially in the Red Sport 400 trim, provides exhilarating acceleration and impressive performance. The 3.7L V6 is also a capable performer.
  • Distinctive Styling: The Q50's sleek and aggressive design stands out from the crowd.
  • Available Technology: Features like adaptive cruise control, blind-spot monitoring, and a surround-view camera enhance safety and convenience.
  • Value Proposition: The Q50 often offers a better value compared to its European competitors, providing similar features and performance at a lower price point.

Cons:

  • InTouch Infotainment System: The outdated infotainment system can be frustrating to use.
  • Direct Adaptive Steering (DAS): The artificial steering feel can be a turn-off for some drivers.
  • Ride Quality: The ride can be firm, especially on models with sport-tuned suspensions and larger wheels.
  • Interior Quality: While generally well-appointed, the interior materials and overall design are not as luxurious as some of its rivals.

Buying Advice

Here's some advice to help you choose the right Infiniti Q50 for your needs.

Years to Look For:

  • 2017 and Newer (with the 3.0t engine): These models benefit from the updated engine, revised styling, and improved suspension. Pay close attention to maintenance records, especially regarding oil changes and potential turbocharger issues. Aim for 2019+ for standard Apple CarPlay/Android Auto.
  • 2016 (with the 2.0t engine): If fuel economy is a priority, the 2.0t engine offers a good balance of performance and efficiency.

Years to Potentially Avoid (or Inspect Carefully):

  • Early 3.0t Models (2017-2018): These models are potentially more prone to turbocharger failures. Thorough inspection and maintenance records are crucial.
  • Models with Direct Adaptive Steering (DAS): Unless you specifically desire the DAS system, consider models without it to avoid potential maintenance complexities.

Pre-Purchase Inspection:

  • Have a qualified mechanic inspect the vehicle: Focus on the engine (especially turbocharger health on the 3.0t), transmission, suspension, and electrical systems.
  • Check for oil leaks: Pay close attention to the valve covers, turbochargers, and oil pan.
  • Test all electronic features: Ensure that the infotainment system, driver-assistance systems, and other electronic features are functioning correctly.
  • Review the vehicle's maintenance history: Look for evidence of regular oil changes, transmission fluid changes, and other preventative maintenance.
  • Test drive the vehicle extensively: Pay attention to the steering feel, ride quality, and engine performance.

By following this guide and conducting thorough research, you can make an informed decision and find the perfect Infiniti Q50 to suit your needs and preferences. Happy hunting!
