2015 Infiniti Q50 Review

The 2015 Infiniti Q50 has a potent engine, and the base suspension returns good handling. Inside, the cabin is posh and spacious. A poor reliability rating pushes the Q50 to the bottom half of our upscale small car rankings. 

Pros & Cons


  • Robust, fast V6 engine
  • Vigorous handling
  • Upscale cabin materials



  • Complicated dual-screen infotainment system
  • Lower fuel economy than many rivals
  • Optional steering system lacks response


2015 Infiniti Q50 Overview

Is the 2015 Infiniti Q50 a Good Used Car?

The base 2015 Infiniti Q50 is a good upscale small car if you want to have some fun behind the wheel. In this competitive class, however, there are better options. The Q50’s fuel economy is low for the class, and the infotainment system is overly complex.

Used 2015 Infiniti Q50 Performance and Interior

A 328-horsepower V6 engine is standard and provides quick acceleration. Rear-wheel drive is standard, and all-wheel drive is available. With this powerful engine comes below-average fuel economy, however. The rear-wheel-drive 2015 Q50 earns an EPA-estimated 20 mpg in the city and 29 mpg on the highway.

On the road, the Q50 delivers impressive driving dynamics, with agile handling through turns, strong brakes, and a placid ride. Try to avoid models equipped with the available adaptive steering system steering. It’s less responsive than the standard steering system.

The 2015 Infiniti Q50 is a five-seat upscale small car. Its quiet cabin features a sleek design and first-rate materials. Both the front and rear seats provide plenty of support and room. The outboard seats contain anchors for attaching child seats. Some may find the InTouch infotainment system, with an upper 8-inch touch screen and a lower 7-inch touch screen, complicated to operate. It becomes easier to use, however, with practice.

Standard features in the 2015 Infiniti Q50 include push-button start, Bluetooth, two USB ports, an auxiliary audio input, and satellite radio. It’s available with many notable advanced safety features, detailed below.

Used 2015 Infiniti Q50 Prices

The average price of a used 2015 Q50 ranges from about $25,500 for the base model with rear-wheel drive to around $31,200 for the Q50 S with all-wheel drive. However, pricing varies widely depending on the car’s location, mileage, condition, and features.

How Reliable Is the 2015 Infiniti Q50?

With a score of 2.5 out of five from J.D. Power and Associates, the 2015 Q50’s predicted reliability rating is below average for the industry and one of the worst ratings in the class.

How Safe Is the Q50?

The Infiniti Q50 performed decently in crash tests, earning five out of five stars for overall safety from the National Highway Traffic Safety Administration. It also earned five stars in the side and rollover evaluations and four stars in the frontal crash test. The Insurance Institute for Highway Safety named the Q50 a 2015 Top Safety Pick+ and gave it the best rating of Good in four crash tests (moderate overlap front, side impact, rear crash protection, and roof strength). It received the second-lowest rating of Acceptable in the small overlap front crash test.

The 2015 Q50 comes standard with a rearview camera. Many advanced safety systems are available, including parking sensors, blind spot monitoring, adaptive cruise control, backup collision intervention, a 360-degree camera system, forward collision warning, forward emergency braking, lane departure warning, and lane keep assist, forward predictive collision warning (which scans for speed changes two cars ahead of you), and distance control assist (which helps you maintain a safe distance from the vehicle in front of you).

Should I Consider Another Used Q50?

2015 marked the second year of the Q50’s first generation, which includes the 2018 model. There were no major changes for 2015, so you can likely save some money by purchasing a similarly equipped 2014 model. There were significant changes for the 2016 model year, however, such as new engine choices (including a new base engine), an updated steering system, and a new trim.

Which Used Infiniti Q50 Is Right for Me?

The Infiniti Q50 is available in three trim levels: base, Premium, and the sport-focused Q50 S. Each trim comes with a 3.7-liter V6 engine, a seven-speed automatic transmission, and rear-wheel drive. All-wheel drive is available. A Q50 Hybrid model is also available and reviewed separately.

The base Q50 comes with synthetic leather upholstery, dual-zone automatic climate control, two touch screens, Bluetooth, an auxiliary jack, two USB ports, a six-speaker stereo, satellite radio, eight-way power-adjustable front seats, and push-button start. Models equipped with all-wheel drive also come with a heated steering wheel.

The 2015 Q50 Premium trim adds heated front seats, a sunroof with a power sunshade, and a 14-speaker Bose stereo. Some used models may come with navigation, adaptive steering, a proximity key, maple wood trim, rain-sensing wipers, adaptive headlights, an Around View monitor with front and rear parking sensors, adaptive cruise control, distance control assist, forward emergency braking, lane departure warning, lane departure prevention, blind spot warning, predictive forward collision warning, and cross traffic alert.

The Q50 S is the sport trim, adding paddle shifters, leather-trimmed sport seats, and aluminum pedals. It’s also available with all the Q50 Premium trim’s available features.

Because of the Q50’s poor predicted reliability rating, it’s a good idea to consider a certified pre-owned Infiniti. The Infiniti certified pre-owned 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 Q50 and Other Cars to Consider

Which Is Better: 2015 Infiniti Q50 or 2015 Lexus RC?

The Lexus RC is among the best cars in the class. Because it’s a two-door sport-focused coupe, it's much different from the Q50. However, there are several reasons to consider it over the Q50. It's the only car in the class to earn a perfect predicted reliability rating, and it gets excellent safety scores. It's also more athletic than the Q50, while maintaining ride comfort. However, it isn’t nearly as spacious inside as the Q50.

Which Is Better: 2015 Infiniti Q50 or 2015 Mercedes-Benz C-Class?

The comfort-focused Mercedes-Benz C-Class can’t match the Q50 for athletic driving, but it is fairly composed around corners. It has a number of available engines, including a powerful base turbocharged four-cylinder that gets better fuel economy estimates than the Q50’s engine. The C-Class also has one of the most luxurious cabins in the class, and it was our 2015 Best Upscale Small Car for Families.
