Overview & Reviews

The Mercedes-Benz GLK-Class may be one of the least expensive models the German company produces, but you wouldn't suspect that by the way this small crossover looks, feels and drives. Close one of the doors or drive over a set of railroad tracks and you can't help but feel the sense of over-engineered solidity that permeates every inch of this compact luxury SUV. Indeed, it's this innate Benz quality that sets the GLK apart from the other crossovers in its class.

However, there are now more competitors in this class than ever before. Most match the GLK in terms of available equipment and performance, yet also offer a roomier backseat and cargo area. As such, the GLK probably isn't the most family-friendly choice. Even so, that unmistakable Mercedes-Benz engineering and craftsmanship makes the GLK-Class worth a look.

Current Mercedes-Benz GLK-Class
The Mercedes-Benz GLK-Class is a five-passenger premium crossover SUV offered in two trim levels: the gasoline-powered GLK350 and the diesel GLK250 Bluetec variant.

The GLK350 is powered by Mercedes' familiar 3.5-liter V6 that develops 302 horsepower and 273 pound-feet of torque. A seven-speed automatic transmission is standard. The GLK250 Bluetec utilizes a 2.1-liter four-cylinder diesel engine that makes 200 hp and 369 lb-ft of torque, along with the seven-speed automatic. Mercedes' 4Matic all-wheel-drive system is optional on the GLK350 and standard on the GLK250 Bluetec.

GLKs come standard with dual-zone climate control, power front seats, leatherette upholstery, Bluetooth and a six-speaker audio system. Optional luxuries include a panoramic sunroof, a navigation system, a rearview camera and a premium surround-sound audio system. Buyers can also opt for rear-seat DVD entertainment, full leather seating, bi-xenon headlights, rear parking sensors and a multitude of cosmetic appearance options.

Drive the Mercedes-Benz GLK350 back to back with a C350 sedan and you're bound to notice similarities. The steering feel and ride quality are remarkably similar, and the GLK's interior has many identical controls. Both have impressive materials and fit and finish. To go along with its blocky exterior styling, however, the look of the GLK's interior is more austere and upright. In back, rear seat space is surprisingly good for two adults, though getting in and out can be a squeeze. Maximum cargo capacity is noticeably less than what's provided by most other luxury competitors.

On the road, the GLK's V6 delivers smooth and snappy performance, with 0-60-mph sprints right at the 6-second mark. While not the equal of more agile rivals like the BMW X3 or Infiniti EX35, the GLK350's handling is certainly capable and confidence-inspiring around corners. The GLK250 Bluetec brings the segment's first diesel engine and takes about 2 seconds longer to hit 60 mph. The obvious trade-off is significantly increased fuel economy: The Mercedes-Benz GLK250 Bluetec is rated at 28 mpg combined, versus 21 combined for the GLK350 4Matic.

The GLK's ride is firm in typical Germanic fashion, but it absorbs rutted bumps easily and masters even rough highways without the slightest hint of harshness or chatter. In such conditions, the cabin remains impressively quiet, with very little wind or road noise.

Used Mercedes-Benz GLK-Class Models
The Mercedes-Benz GLK-Class was introduced for 2010. In that first year, the GLK lacked the current car's driver's knee and front side hip airbags. The AMG Sport package was also not available. The 2013 model year saw the debut of the GLK250 Bluetec diesel, along with an increase in the V6's power output (previously 268 hp and 258 lb-ft of torque) and improved fuel economy. Other changes that year included a slight styling update inside and out, an automatic stop-start system (that turns off the engine when the vehicle stops to save fuel) and enhanced electronics and infotainment features.

  Comfortable Capable Cruiser; Unreliable - 2010 Mercedes-Benz GLK-Class
  By Justice Charles & Co - August 23 - 10:30 am

  Traded in a leased MB ML350 and decided to downsize now that the kids are driving alone. Had several unresolved issues with the ML but decided to give MB a fresh chance. Overall, my wife and I enjoy driving this right sized SUV. Im 62" but I fit comfortably and the position is good although rear seat comfort and room is cramped. Large double sunroof is nice touch. Nice interior design but cheap/loose bits have surfaced in less than 6 months 7k miles. Fuel is acceptable at 17MPG average. Reliability has been horrific- two individual instances of electrical failure in the stability control system/ABS/ESP. Navigation sys was replaced. Climate control failure, was waiting 3 weeks for part.

  THE GLK 350 MYTH- EDITH - 2015 Mercedes-Benz GLK-Class
  By EDITH - September 11 - 9:07 am

  This is a great car until you become familiar with it. It has looks,style and attractiveness,but the pros generally stop there. None of the controls are intuitive. The voice commands only control the nav system. My 2014 Honda Accord Touring could make calls,turn on the air, ch ange the temperature and several other things. This car is luxury in name only,because it has the Mercedes name tag. In my personal opinion, the cost to value ratio is about 75%. I would not buy this vehicle again

  Baby Benz SUV - 2015 Mercedes-Benz GLK-Class
  By Robert Socha - May 4 - 12:48 am

  Looked at this as needed something good on gas as switched from Telecommuter to having to go into an Office. The estimated mpg of 24-33 with combine 29mpg very attractive. Also, wanted AWD and the higher sitting position. Unfortunately, vehicle is not made for a taller person (Im 63"). I Could not find a comfortable driving position even with all the adjustments. Barely could get in/out of backseats as the rear doors are small and do not open that far. The dashboard/instrument cluster color combination of Silver/Gold/White made it extremely difficult to see the numbers on the gauges. Overall, the vehicle was just too small for me and my family of 5.

  brake issue - 2010 Mercedes-Benz GLK-Class
  By Pat Spivey - January 30 - 12:56 pm

  Purchased 20l0 GLK on 02/l4/09. Brakes were soft and spongy. In May 2009, daughter drove the car and commented on the brakes not stopping when pressed immediately. Took car through a car wash and on the way home, brakes failed at a traffic light and I hit a car on the left side bumper and taillight. I have been driving 55 years and have never had an accident. Mercedes Benz of Knoxville said they knew of no brake problems and would have Mercedes USA look into the matter. It took 40 days to get my car repaired and cost me $900 additional in rental car expenses. Told Mercedes of Knoxville that I liked the car, but was afraid to drive it. Said they would trade with me for $ll,000 more.

  2010 GLK350 - 2010 Mercedes-Benz GLK-Class
  By mercedes2010 - August 13 - 4:22 pm

  Great car mechanically however, if you are over 58" tall and weigh more than 180 pounds, not the car for you! After 13500 miles, the drivers side door rubber and interior molding is completely worn out from entrance and exit "rubbing"!! Poor quality materials as far as I am concerned. When taken and shown to the dealer he indicated this wear was not covered by warranty. Would expect this after 40 - 50 thousand miles but not from a new car, especially a mercedes. Stay aware if your an average person!!

  I Love My Car But... - 2010 Mercedes-Benz GLK-Class
  By B.R.Bannister - December 22 - 3:05 am

  I Love my Car. We are around 110000 miles now. Over all I love everything about my car except I always need to fix it. My car lock needed to be fixed, that was $1000 Seals around the doors are cracking. Chrome trim around cup holders are peeling. Buttons are wearing off. Middle console it scratching. Basically anything plastic will and has fallen apart. I know it sounds all horrible but my car in almost mint condition and all these things are things only I would notice since I detail my car daily but the fact is I have noticed. Ive spent $3000 in maintenance this year. Over all I love my car it handles well, I feel special driving it. But if you dont have the extra cash Id say pass.

  One month in a GLK - 2010 Mercedes-Benz GLK-Class
  By Dr. Sunumo - April 11 - 2:56 pm

  Traded in our BMW X3. Overall, the GLK is a better SUV. It holds more cargo, has good power and never feels heavy. The biggest problem to report has to do with electronic problems- from the power seats to the rear latch to the A/C controls which shorted out. Already needed additional oil and the system check light alerted us of engine/EC problems. Build quality is low to average. The COMAND info system is good but not great:the knob is placed in a very odd position behind shifter. Why? The brakes are soft and fade from highway speeds. It needs premium gas and at 14.1 MPG average, it needs plenty of gas. There is no place for cell phones- only in small cup holders. Little back seat room.
