Infiniti QX30: A Comprehensive Guide

The Infiniti QX30 is a compact luxury crossover SUV produced by Nissan's luxury division, Infiniti, from 2017 to 2019 in North America and 2020 elsewhere. It was designed to appeal to buyers seeking a premium small crossover with sporty styling and a luxurious interior. The QX30 was based on the same platform as the Mercedes-Benz GLA-Class, a result of a collaboration between Daimler and the Renault-Nissan Alliance.

Generations

First Generation (2017-2020)

  • Years: 2017-2020 (North America: 2017-2019, Rest of World: 2017-2020)
  • Key Features:
    • Platform: Mercedes-Benz MFA platform (shared with GLA-Class)
    • Engine: 2.0L Turbocharged Inline-4 (208 hp, 258 lb-ft torque)
    • Transmission: 7-speed Dual-Clutch Automatic
    • Drivetrain: Front-wheel drive standard, all-wheel drive optional (called QX30 AWD)
    • Styling: Distinctive, coupe-like crossover design. Three main trim levels: Base, Luxury, and Premium, with subtle styling differences. The 'Sport' trim was lower and more aggressively styled.
    • Interior: High-quality materials, comfortable seating, and available features like leather upholstery, panoramic sunroof, and advanced infotainment system.
    • 2019 Facelift (Rest of World): Subtle exterior changes, improved infotainment system. This facelift was not released in North America before its discontinuation.

Reliability & Common Issues

The Infiniti QX30, being heavily based on Mercedes-Benz components, shares many of the reliability characteristics (and potential issues) of the GLA-Class. Here's a breakdown of common problems:

  • Engine Issues:
    • Oil Leaks: The 2.0L turbocharged engine can be prone to oil leaks, particularly around the valve cover gasket and oil filter housing. Regular inspection and timely repairs are crucial.
    • Turbocharger Problems: While generally reliable, turbochargers can fail due to oil starvation or excessive wear. Listen for unusual noises or a loss of power. Ensure proper oil change intervals are strictly followed.
    • High-Pressure Fuel Pump (HPFP): Failures of the HPFP have been reported. Symptoms include rough idling, stalling, and difficulty starting.
  • Transmission Issues (DCT):
    • Rough Shifting: The 7-speed dual-clutch transmission (DCT) can sometimes exhibit rough or jerky shifting, particularly at low speeds. Software updates may alleviate some of these issues. Ensure the transmission fluid has been changed according to the manufacturer's schedule.
    • Mechatronic Unit Failure: The mechatronic unit, which controls the transmission's shifting, can fail. This is a more serious and costly repair.
  • Electrical Issues:
    • Infotainment System: The infotainment system, especially pre-2019 models, can be slow and buggy. Software updates are available, but may not completely resolve the issues.
    • Sensor Failures: Various sensors, such as those related to the parking assist and blind-spot monitoring systems, can fail.
    • Battery Issues: The QX30, like many modern cars, is sensitive to battery voltage. A weak or failing battery can cause a variety of electrical problems.
  • Suspension and Steering:
    • Suspension Components: The suspension components, particularly the front struts and bushings, can wear out prematurely, especially on models driven on rough roads.
    • Alignment Issues: Due to the relatively low ride height (especially on the Sport trim), the QX30 is susceptible to alignment issues from hitting potholes or curbs.
  • Other Issues:
    • Water Leaks: Some owners have reported water leaks, often traced to the sunroof seals or improperly sealed tail lights.

Overall Reliability: The QX30's reliability is generally considered average to slightly below average for the luxury compact crossover segment. Regular maintenance, adherence to recommended service intervals, and addressing problems promptly are crucial to ensure long-term reliability. Consider getting a pre-purchase inspection by a qualified mechanic experienced with Mercedes-Benz vehicles.

Driving Experience

The Infiniti QX30 offers a unique blend of sporty handling and luxurious comfort, albeit with a few compromises.

  • Pros:
    • Sporty Handling: The QX30 handles well, especially the Sport trim, thanks to its lower ride height and firmer suspension. It feels planted and responsive in corners.
    • Comfortable Ride (Except Sport): The standard and Luxury/Premium trims offer a comfortable ride for daily commuting and long trips. The Sport trim sacrifices some comfort for improved handling.
    • Powerful Engine: The 2.0L turbocharged engine provides ample power for most driving situations. Acceleration is brisk, and the engine feels responsive.
    • Stylish Interior: The interior is well-designed and uses high-quality materials. The seats are comfortable and supportive, and the cabin is generally quiet.
    • Unique Styling: The QX30 stands out from the crowd with its distinctive, coupe-like crossover design.
  • Cons:
    • Limited Rear Headroom and Cargo Space: The sloping roofline compromises rear headroom and cargo space. It's not the most practical choice for families who need a lot of room.
    • DCT Hesitation: The dual-clutch transmission can sometimes exhibit hesitation or jerky shifting at low speeds, which can be annoying in stop-and-go traffic.
    • Infotainment System: The pre-2019 infotainment system is dated and can be slow and cumbersome to use.
    • Visibility: Rear visibility is somewhat limited due to the small rear window.
    • Ground Clearance (Sport Trim): The Sport trim has very low ground clearance, making it unsuitable for driving on unpaved roads or in snowy conditions.

Buying Advice

If you're considering buying a used Infiniti QX30, here's some advice:

  • Years to Look For: The 2019 models (available outside North America) are preferable, as they feature subtle styling updates and an improved infotainment system. However, these are difficult to find in the North American market. Therefore, focus on well-maintained 2017-2018 models.
  • Years to Avoid (Potentially): None specifically, but prioritize models with thorough service records. Lower mileage examples are generally better, but a well-maintained higher-mileage car can be a good value.
  • Trim Levels: Consider your needs and preferences. The Luxury or Premium trims offer a good balance of comfort and features. The Sport trim is best for those who prioritize handling over comfort and don't need maximum ground clearance.
  • Check for Maintenance Records: Thorough maintenance records are crucial. Look for evidence of regular oil changes, transmission fluid changes, and other preventative maintenance.
  • Pre-Purchase Inspection: Have a qualified mechanic, preferably one familiar with Mercedes-Benz vehicles, perform a pre-purchase inspection to identify any potential problems. Pay close attention to the engine, transmission, suspension, and electrical systems.
  • Test Drive Thoroughly: Test drive the vehicle in a variety of driving conditions to assess its handling, ride quality, and transmission performance. Pay attention to any unusual noises or vibrations.
  • Negotiate Wisely: The QX30 depreciates relatively quickly, so you should be able to negotiate a fair price. Research the market value of similar vehicles in your area before making an offer.
  • Consider Extended Warranty: Given the potential for costly repairs, especially related to the engine and transmission, consider purchasing an extended warranty from a reputable provider.
  • Be Aware of the Platform: Remember that the QX30 shares many components with the Mercedes-Benz GLA-Class. This can be helpful when sourcing parts and finding qualified mechanics.

By following these tips, you can increase your chances of finding a reliable and enjoyable Infiniti QX30.
