2015 Mercedes-Benz GLK-Class Overview

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

The 2015 Mercedes GLK is a great pick among luxury compact SUVs. The GLK is available with two potent engine options, and it rewards drivers with its comfortable ride and agile handling. It rates highly for reliability and crash safety, and it’s available with many advanced safety features. The GLK’s interior is also very well-trimmed.

Overall, it’s a pleasant SUV to drive, though its cargo area and backseat are a bit small. If this is a deal breaker for you, consider the brand’s larger SUVs like the 2015 GL and 2015 M-Class.

How Much Does the 2015 Mercedes-Benz GLK Cost to Own?

The GLK’s five-year costs for gas, insurance, repairs, and maintenance are projected to be $29,700, or about $5,900 per year. That’s about average for a luxury compact SUV.

Is It Better to Buy a Used or New GLK?

The GLK-Class was discontinued after the 2015 model year, so you won’t find any new models for sale. However, you can buy its replacement, the 2019 Mercedes-Benz GLC. The GLC's pricing starts at around $41,000. It offers a longer list of tech features like Apple CarPlay and Android Auto, as well as more powertrain options like a plug-in hybrid and a beastly 500-horsepower V8. The GLC and GLK share many of the same active safety features, and both sport well-dressed cabins. If you’d prefer to save money, you may be just as happy with a used GLK.

You can find plenty of new SUVs that cost less than a used 2015 GLK – just not any luxury vehicles. However, there are several new compact SUVs worth considering. The 2019 Volkswagen Tiguan starts at $24,295, and it offers an upscale interior, a comfortable ride, and seating for up to seven. The 2019 Honda CR-V ($24,350) has loads of cargo space and returns great fuel economy of up to 28 mpg in the city and 34 mpg on the highway. The 2019 Mazda CX-5 ($24,350) may not be a luxury SUV, but its handsome interior and sporty handling might fool you into thinking it is one.

Which Model Year of the Mercedes-Benz GLK Is Best?

The first and only generation of the GLK-Class spans the 2010 to 2015 model years. There were few updates throughout this generation, but the biggest changes arrived for 2013. The GLK-Class received sharper exterior styling, higher-quality cabin materials, a V6 engine with more power, and a fuel-efficient turbodiesel engine. The GLK-Class also gained more safety features like adaptive cruise control, forward collision warning, and blind spot monitoring. These refinements make the 2013 to 2015 GLK-Class models the best choices.

2015 Mercedes-Benz GLK Recalls

As of this writing, there are four recalls for the 2015 GLK. Mercedes-Benz is recalling models due to defective Takata air bags that could rupture in the event of a crash. Other recalls address potential issues with the steering column, driver-side air bag, and a possible oil leak at the timing chain tensioner gasket (BlueTec models only). Make sure these recalls have been addressed by a Mercedes dealer before buying a used GLK SUV.

What Does Mercedes-Benz's Certified Pre-Owned Warranty Cover?

Mercedes-Benz offers a certified pre-owned program for vehicles six years old or less and with fewer than 75,000 miles. Eligibility is determined by the vehicle’s initial sale date. 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. This warranty can be renewed for a fee. If the new-car warranty has expired, you’ll receive the one-year warranty with unlimited mileage. Every Mercedes-Benz CPO vehicle must pass a 165-point inspection.

If you’re unsatisfied with your CPO vehicle, Mercedes’ Exchange Privilege program allows you to exchange it for another CPO vehicle of equal or lesser value within seven days or 500 miles. Additional benefits like towing and 24-hour roadside assistance may be available, so read the Mercedes-Benz warranty page carefully.

Among luxury car manufacturers, Mercedes-Benz’s CPO program is about average. It’s better than BMW’s but not as robust as Jaguar’s or Lexus’, according to our analysis.

2015 Mercedes-Benz GLK Versus the Competition

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

The 2015 BMW X3 and GLK are both great options in the luxury compact SUV class. These SUVs have solid reliability ratings, similar active safety features, classy interiors, and comparably strong engine options, including fuel-efficient diesel engines. The GLK offers a smoother ride on rough pavement. On the other hand, the BMW has a simpler infotainment system and a larger cargo area. Test drive both to see which SUV you prefer.

Which Is Better: 2015 Mercedes-Benz GLK or 2015 Audi Q5?

The 2015 Audi Q5 may have a lovely cabin and sporty handling, but it isn’t a great used SUV. The Q5 has higher-than-average ownership costs and a low reliability rating. Additionally, the Audi has an awkward infotainment system, and it offers fewer active safety features than the GLK. The Mercedes is a better bet.

2015 GLK Performance

How Does the 2015 Mercedes-Benz GLK Drive?

The 2015 GLK has two engine options: a 3.5-liter V6 with 302 horsepower (GLK 350) and a 2.1-liter turbodiesel four-cylinder with 200 horsepower (GLK 250 Bluetec). A seven-speed automatic transmission and rear-wheel drive are standard; 4Matic all-wheel drive is available.

The V6 feels muscular, hustling the GLK up to speed briskly. It also supplies ample power for climbing hills and passing slower vehicles. The twin-turbo diesel engine feels just as zippy once the SUV is up to speed, though initial acceleration from a stop is a little slow. The seven-speed transmission earns praise for its quick, smooth gear changes. The GLK-Class rides comfortably over most road surfaces, and its suspension absorbs bumps and dips nicely. This Mercedes also remains quite stable around turns, and its steering feels light and responsive.

Does the 2015 Mercedes-Benz GLK Get Good Gas Mileage?

The diesel-powered GLK 250 Bluetec gets an EPA-estimated 24 mpg in the city and 32 mpg on the highway, which is great fuel economy by class standards. The gas-powered GLK 350 gets decent fuel economy of up to 19 mpg in the city and 26 mpg on the highway. AWD versions of this model get 1 less mpg city/highway.

2015 Mercedes-Benz GLK Towing Capacity

The GLK is rated to tow up to 3,500 pounds, when properly equipped.

2015 GLK Interior

How Many People Does the 2015 GLK Seat?

The Mercedes GLK is a two-row SUV with five seats. The front seats are comfortable, and they offer adequate head- and legroom for taller drivers and passengers. The tall windshield and boxy cabin shape provide good outward visibility. The rear seats offer plenty of room for kids and teens, but legroom is a bit tight for adults. The rear door openings are also rather slim, making it awkward for tall passengers to get in and out of the back seat. MB-Tex synthetic leather upholstery is standard; genuine leather upholstery and heated front seats are available.

The GLK’s interior is elegantly designed, and it’s trimmed with quality materials. The cabin remains very quiet when driving around town, but wind noise gets a bit loud at highway speeds.

How Many Car Seats Fit in the 2015 Mercedes-Benz GLK?

The GLK has two full sets of LATCH connectors for securing child car seats.

2015 Mercedes-Benz GLK Features

The GLK comes standard with a 5.8-inch infotainment screen, Bluetooth, and a CD player. Available features include a navigation system with a 7-inch screen, satellite radio, rear-seat DVD players, and a sunroof.

The infotainment screen has crisp graphics, and it’s located high on the dashboard, making it easy to see. The audio and climate controls are easy to use, but the navigation system is a bit complicated. You control it by using a knob on the center console and additional buttons on the dashboard.
