2012 Mercedes-Benz GLK-Class Overview

By Cars.com Editors
Vehicle Overview

Mercedes-Benz entered the small luxury crossover segment in 2010 with the GLK-Class, which seats up to five people in two rows. Offered in GLK350 form with a 3.5-liter V-6 engine and either rear- or all-wheel drive, it features recognizable Mercedes styling cues and available high-tech features.

The GLK350 competes with luxury crossovers like the Audi Q5, Acura RDX and BMW X3.


New for 2012
There are no significant changes for 2012.

Exterior
With its angular exterior styling, the GLK350 bears a strong resemblance to its big brother, the GL-Class. The GLK350's large front grille is divided by horizontal bars, and in the middle is a large Mercedes three-pointed star. Upright roof pillars make for tall side windows, and the back of the crossover is finished with a liftgate spoiler and twin exhaust outlets. Exterior features include:

  • Standard 19-inch alloy wheels
  • Optional 20-inch rims
  • Optional panoramic moonroof and power liftgate
  • Optional adaptive bi-xenon headlights, cornering lights and LED taillights


Interior
Models equipped with Mercedes' optional Comand system have a knob controller on the center console that's used to navigate menus on the 7.5-inch dash screen. Among knob-based control systems, Comand's interface is one of the more intuitive ones available. The system's screen can show things like radio station information and map data from the navigation system. For 2012, the media interface moves to the center console. Interior featu...

Very Reliable

by Susieqtoo37 from East Hartford CT on February 15, 2018

It’s a great car, at almost 80k, I have done no major repairs yet. Front seat is comfortable but back seat is very small. I had to pull up the front seat to allow a car seat in the back seat. Read full review

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
