2015 Infiniti QX50 Review

The 2015 Infiniti QX50 (formerly the Infiniti EX) sits in the bottom half of our luxury compact SUV rankings. It gets strong performance from its V6 engine and it has an upscale interior, but others in the class have more cargo room and better predicted reliability ratings. 

Pros & Cons


  • Agile handling
  • Powerful V6


  • Cramped rear seats
  • Limited cargo space

2015 Infiniti QX50 Overview

Is the 2015 Infiniti QX50 a Good Used SUV?

The QX50 is a good SUV if you're looking for a high-quality interior with top-notch materials, a powerful engine, and agile handling. However, if you plan on hauling cargo or driving with tall passengers, the QX50's limited cargo space and cramped rear seats will disappoint.

Used 2015 Infiniti QX50 Performance and Interior

The 2015 Infiniti QX50 comes with a 325-horsepower V6 engine and a seven-speed automatic transmission. Rear-wheel drive is standard and all-wheel drive is available. This crossover earns 17 mpg in the city and 25 mpg on the highway. All-wheel-drive models earn 24 mpg on the highway. These are low estimates for a luxury compact SUV.

The QX50 has plenty of power to accelerate up to passing speeds, and the transmission delivers smooth, quick shifts. This Infiniti is nimble, with well-balanced handling. It corners sharply and has communicative steering and strong brakes.

This Infiniti crossover seats five on standard leather upholstery and comes with power-adjustable front seats. Heated front seats and a moonroof are available. The front seats are comfortable and supportive with ample head- and legroom. Headroom in the rear seats is also comfortable, though legroom is lacking. There are two complete sets of LATCH car-seat connectors in the rear outboard seats and an upper-tether connector in the middle seat.

Standard features include a USB port, a 7-inch display, Bluetooth, push-button start, and satellite radio. Available features include navigation, voice recognition, an 11-speaker Bose sound system, and a 7-inch touch screen.

The infotainment system is easy to operate, and the display and touch screen are easy to read. The navigation, climate, and audio controls are all separate, which make them simple to use.

How Safe Is the QX50?

The 2015 QX50 only underwent one crash test by the National Highway Traffic Safety Administration, receiving four of five stars in the rollover crash test. The Insurance Institute for Highway Safety gave it Good scores (the highest possible) in four crash test categories (it was not tested in the small overlap front test category).

A rearview camera comes standard in all QX50s. Available safety features include a 360-degree camera, blind spot monitoring, forward collision warning, front and rear park assist, and adaptive cruise control.

Should I Consider Another Used QX50?

The 2015 QX50 (formerly called the Infiniti EX) is part of the SUV's first generation, which launched with the 2008 model year and includes the 2017 model. The SUV received a new V6 engine for the 2013 model year. For 2016, Infiniti lengthened the QX50's wheelbase – creating much more rear-seat space – and added heated front seats, a moonroof, and more to the standard features list. If those improvements don't interest you, you can likely save money by purchasing a 2013 or 2014 model.

Which Used Infiniti QX50 Is Right for Me?

The 2015 Infiniti QX50 comes in two trims: the base QX50 and QX50 Journey. All-wheel drive is available in both trims. For the best value, go with the QX50 Journey. It comes standard with a moonroof, a rearview camera, leather upholstery, heated front seats, and a 7-inch touch screen with Bluetooth. Its many available features include navigation, voice recognition, a 360-degree camera, forward collision warning, and blind spot monitoring.

For added peace of mind, you may want to consider a certified pre-owned QX50. The Infiniti CPO warranty has three levels of coverage based on the vehicle’s age and mileage. Vehicles with less than 15,000 miles receive a six-year/75,000-mile warranty from the original new-car purchase date. Vehicles less than four years old with more than 15,000 miles receive a six-year/unlimited-mileage warranty from the original new-car purchase date. Finally, vehicles more than four years old with more than 15,000 miles receive a two-year/unlimited-mileage warranty good from the CPO purchase date. Infiniti CPO vehicles must pass a 167-point inspection. Additional benefits like towing and roadside assistance may be available, so read the Infiniti warranty page carefully.

2015 Infiniti QX50 and Other SUVs to Consider

Which Is Better: 2015 Infiniti QX50 or Acura RDX?

The Acura RDX won our 2015 Best Luxury Compact SUV for the Money award thanks to its responsive V6 engine, comfortable ride, and high-quality interior. The RDX's V6 doesn't produce as much horsepower as the QX50's, but it still offers quick highway acceleration. The RDX has agile handling and is more fuel-efficient than the QX50, achieving 20/28 mpg city/highway. The RDX also has a higher predicted reliability rating and a lower predicted cost of ownership, giving it the edge over the QX50.

Which Is Better: 2015 Infiniti QX50 or Audi Q5?

The Audi Q5 is like the QX50 in that it has an upscale interior and nimble handling. Both SUVs also have strong acceleration, but the Q5 offers multiple powerful engines, whereas the QX50 only offers one. The Q5 comes standard with all-wheel drive, but its ride can be too firm and uncomfortable. Additionally, its infotainment system is difficult to use. The QX50's lower predicted cost of ownership and higher safety scores make it the SUV to buy.

Which Is Better: 2015 Infiniti QX50 or 2015 Infiniti QX70?

The Infiniti QX70 is a luxury midsize SUV, and aside from having slightly more cargo space, it's comparable to the QX50. The cabin has premium materials and is mostly comfortable, but rear-seat legroom is cramped. Both SUVs come with a 325-horsepower V6 that produces strong acceleration, and they both get similar fuel economy estimates. The QX50 and QX70 have easy-to use infotainment systems and come with similar standard and available features. You can save money by going with the QX50 and get largely the same SUV.
