2015 Mercedes-Benz GLK-Class Review

The 2015 Mercedes-Benz GLK-Class sits near the top of the luxury compact SUV class. It’s likely to hold up better over the long haul than its competitors, and it earned high marks in crash tests. It’s not a particularly comfortable vehicle, however; the second row is cramped, the seats aren’t supportive, and some controls are hard to reach. 

Pros & Cons

  • Exceptional fuel economy with GLK250 BlueTEC 4Matic
  • Cabin swaddled in luxury
  • Potent engine
  • Tight rear seat
  • Firm ride

2015 Mercedes-Benz GLK-Class Overview

Is the 2015 Mercedes-Benz GLK-Class a Good Used SUV?

The 2015 Mercedes-Benz GLK-Class is a good SUV that comes with a potent standard V6 engine. A fuel-sipping diesel engine is available. Its opulent interior has five seats, but it realistically can’t hold more than four adults comfortably. This luxury compact SUV is a good choice for small families thanks to its perfect safety scores.

Used 2015 Mercedes-Benz GLK-Class Performance and Interior

The 2015 Mercedes-Benz GLK350 has a 302-horsepower V6 engine that delivers brisk acceleration. The diesel-powered GLK250 BlueTEC comes with a twin-turbo 200-horsepower four-cylinder engine. A seven-speed automatic transmission is standard. The GLK350 has standard rear-wheel drive, while the GLK250 BlueTEC has standard all-wheel drive. All-wheel drive is available in the GLK350. According to the EPA, the base GLK350 earns 19 mpg in the city and 26 mpg on the highway, which is low for the class. However, the turbocharged diesel-powered GLK250’s estimated 24 mpg in the city and 32 on the highway is outstanding.

The 2015 Mercedes-Benz GLK-Class has seating for five, though four is more realistic. It comes standard with a power-adjustable driver’s seat and leatherette upholstery. Leather seats and heated front seats are available. The front seats offer lots of adjustability, but the GLK-Class’ seats aren’t as comfortable as some rivals’. The rear seats are short on legroom and can’t comfortably fit three adults. Narrow door openings and wide running boards make the GLK-Class difficult to exit. Each outboard second-row seat has a complete set of LATCH car-seat connectors, and the middle seat has a tether anchor.

Standard interior features in the 2015 Mercedes-Benz GLK-Class include dual-zone automatic climate control, Bluetooth, and a 5.8-inch display. Available features include Mercedes’ COMAND infotainment system with navigation and a 7-inch display, a Harman Kardon stereo system, and satellite radio. A combination of a command knob, dashboard buttons, and steering wheel controls make operating the stereo and phone settings easy. However, scrolling through letters and numbers to input addresses into the navigation system is time consuming.

Should I Consider Another Used GLK-Class?

The 2015 Mercedes-Benz GLK-Class was produced for just one generation, which launched in 2010 and ended with the 2015 model. In 2016, the GLK-Class was redesigned and rebranded as the Mercedes-Benz GLC-Class. You can save money by buying the 2014 GLK-Class, which is essentially the same as the 2015 model.

Which Used Mercedes-Benz GLK-Class Is Right for Me?

The 2015 Mercedes-Benz GLK-Class comes in two trim levels: the GLK350 and the GLK250 BlueTEC. Apart from the engines, there are few differences between the two trim levels. Both models feature automatic headlights, Bluetooth, dual-zone automatic control, a leather multifunction steering wheel, a 14-way power driver’s seat with lumbar support, and an eight-way adjustable front passenger seat.

You might consider buying a certified pre-owned GLK-Class. Mercedes-Benz certified pre-owned vehicles come with the balance of the original four-year/50,000-mile new-car warranty, plus an additional one-year/unlimited-mileage warranty. If the new-car warranty is expired, you’ll just receive the one-year/unlimited-mileage warranty. Every Mercedes-Benz CPO vehicle must pass a 164-point inspection. Additional benefits like towing and roadside assistance may be available, so read the Mercedes-Benz warranty page carefully.

2015 Mercedes-Benz GLK-Class and Other SUVs to Consider

Which Is Better: 2015 Mercedes-Benz GLK-Class or 2015 Volvo XC60?

The 2015 Volvo XC60 seats five and comes standard with front-wheel drive, while the GLK-Class has rear-wheel drive. Both have available all-wheel drive. The Volvo has a roomier rear seat, better fuel economy, and more cargo space than the GLK-Class. A perfect safety score and near-perfect predicted reliability make the Mercedes-Benz the better choice, unless you need to carry five adults on a regular basis.

Which Is Better: 2015 Mercedes-Benz GLK-Class or 2015 BMW X3?

It’s a toss-up between the 2015 BMW X3 and the GLK-Class. The BMW has sharp handling, powerful available engines, and a spacious cabin with ample room for five adults (something the GLK-Class is not known for). The Mercedes has a slightly higher safety score and better predicted reliability. The X3 is more fun to drive, but the Mercedes should require fewer trips to the mechanic.
