Mercedes will get you to your destination safely and comfortably.

This is my 2nd glk. I loved the first one that it only made since to get another one just like it. Not once did I ever have to worry about its reliability. It got me wherever I wanted to go. I haven't had a thing go wrong with the car since I have owned it. The service I get with the car is impeccable. I would buy this car again and again.

Overall a very smooth running dependable car.

The car is very spacious and drives smoothly. The leather seat are comfortable and the car comes with heated seating. Everything is easy to learn and use. The car will usually notify on the driver's dash if there is any problems. The only odd feature on the car is the aux cord being in the glove compartment. The only issue I have had with the car is the headlights coming on when the car is not on causing the battery to drain.

My vehicle was a new model by Mercedes and space was a problem.

It performed great the first five years. I have had to have major repairs done within the last two years. Last couple of years, I had to have major repairs totaling more that $5, 000. 00. I just had to replace the starter.

George B

Stable, economical, performance, durable.

The car is quite stable, consumption is good and maintenance is low considering its age and mileage. It is stable on the road and given its size it still leaves room for internal comfort. For it is age I will say it is a good car. For a midsize SUV I think it is small though.

Sinnia S

It commands attention due to the strong character and details of the car.

My glk300 was purchased used but in excellent condition. The glk 300 gets about 16 mpg in the city and 23 on the Hwy. It is a luxury compact SUV and a very comfortable ride. It also has many safety features which include driver air bags, anti-lock brakes, v6 engine that has a lot of power. It has multiple cup holders, dual-zone climate control and a panoramic sliding glass sunroof. Power window controls with one-touch up/down.

Erin C

Maintenance costs and upkeep is more expensive than others

My suv is the best! I will never drive anything else other than a Mercedes Benz. You can not compare it to anything else.

Problem with electronic ignition. Had to replace it

Glk-350 what's wrong with yours?

I've had every prob imaginable since the day I drove it off the lot. My air quit that day. I've had airbags come out going down the road Now it starts when it wants to. It's just a lot of different things. Recalls that I took the vehicle in to have fixed that continue to still not work like my trunk opening when it wants to also. My CD player and Bluetooth messed up and made my satellite radio mess up so it also beeps every 30 seconds.

Jessica S

The worst vehicle I've ever had.

I've had more problems with this vehicle than any before. The airbags have deployed going down the road. The battery has to be replaced once a year and the satellite radio or 6 disk CD changer work. Everything fell apart in it. The trunk recall was taken in 3 times but never able to fix.

Shawn B

The AWD is pretty good especially if you have a good set of tires on there.

Bought the car used. It was still in good shape but the drivers seat leather rips on almost every glk class. The AWD system is pretty good but not the quality of Audis AWD system. A lot of plastic in the car and I keep having headlights blow out. I will say that the base model sound system is actually quite impressive.

Jenny D

Drives nicely and feels luxurious.

The car drives nicely and feels luxurious but I have had several expensive problems - mostly brake issues. Many of the interior trim accessories have failed - ie. Broken cup holders, split seams, numbers/icons wearing off. It also has non-user friendly technology.

Love this car - practical and sleek!

This car is amazing and very practical to be a foreign vehicle. There has been very few minor issues and maybe one large issue in the 3 years I have driven it. The gas mileage is not great due to it being a v6 engine, however it could be worse and the engine size really does make the car so fun to drive.

Josh M on May 13, 2021

2010 Mercedes glk350 4matic.

My 2010 Mercedes Benz is a great SUV. It's a great reliable SUV. It is all wheel drive. It's a very luxurious vehicle with luxury features. My Mercedes is very good on fuel economy. I love the panoramic glass roof also. I would say my only complaint would be its a bit small.

Pros from Owners

Anthony N.

The 2010 Mercedes GLK 2010 Model is comfortable, sleek, sporty, and reliable. Its positives are that it gets very good mileage. The stereo system is quite good and powerful and the technology is easy to operate.

Cons from Owners

Anthony N.

It eats up gas rather quickly and its size makes it difficult to fit into tight spaces. Also, if you ever get a flat tire, you may be waiting for a new one for quite awhile, as many Mercedes Dealerships do not carry the required model anymore.
