What Problems Does the 2012 Mercedes-Benz GLK-Class Have?

Frequently reported problems for the 2012 Mercedes-Benz GLK-Class include issues with the fuel level sensor, which can lead to inaccurate fuel readings. Some owners have reported problems with the air conditioning system and the COMAND infotainment system, including glitches and software malfunctions. There have been reports of issues related to the camshaft adjusters which can result in engine knocking. Regarding recalls, it's crucial to check the NHTSA (National Highway Traffic Safety Administration) website for any open recalls related to the specific VIN of the vehicle. Long-term reliability concerns often revolve around the maintenance of the complex Mercedes-Benz systems. Neglecting scheduled maintenance, especially fluid changes and inspections, can lead to more significant and costly repairs down the line. Suspension components, particularly the air suspension (if equipped, though less common on the GLK), can require attention over time. The electrical system is also a potential area of concern, requiring proper diagnostics and care. Regular servicing by a qualified mechanic familiar with Mercedes-Benz vehicles is essential for maintaining the GLK's reliability over the long term. Some earlier model year GLKs (2009-2010) had more prevalent issues compared to the 2012 model, but preventative maintenance is still crucial.

How long will the 2012 Mercedes-Benz GLK-Class last?

With proper maintenance, a 2012 Mercedes-Benz GLK-Class can reasonably provide 200,000 miles or more of service. Many owners report their vehicles lasting well over 10 years with diligent upkeep. Long-term durability depends heavily on maintenance habits. Key weaknesses over time include potential wear and tear on suspension components, particularly bushings and ball joints. The electrical system can also be prone to issues with age. Regular fluid changes (engine oil, transmission fluid, coolant) and timely replacement of wear items (brakes, tires) are crucial for maximizing longevity. Neglecting these items will significantly shorten the vehicle's lifespan.

I own a 2012 Mercedes Benz GLK 350 . I love the performance and look, style and design of the auto. I would recommend this auto to others in that it is worth the investment.
Sandy
I have to say... I thought I wanted a new car... but I am convinced that my older model feels heavier and safer than the new model I was loaned
Ryannn3
Loved the ride. Super smooth. Love the interior - it's got everything and everything works well and is in mint condition. Even the engine was cleaned.
Negative Owner Reviews
jdogg
Does not feel in tune with the road. No control and makes you feel disconnected from the road. Otherwise I love the style for this car, it's a very beautiful car. Too bad the performance disappointed me.

What Technology & Safety Features are Included?

The 2012 Mercedes-Benz GLK-Class comes standard with features like Bluetooth connectivity, an eight-speaker audio system, and a central display screen controlled by a knob on the center console. Optional tech included a navigation system, rearview camera, voice control, and enhanced media interface (part of the Multimedia Package). Driver-assistance features, available as part of the Driver Assistance Package, included blind spot monitoring and lane keeping assist.

Standard safety features included antilock brakes, stability control, traction control, front and rear side airbags, side curtain airbags, and active front head restraints. The GLK-Class also included Mercedes-Benz's mbrace telematics system (subscription required) which offered emergency assistance, remote vehicle access, and other convenience features.

Crash test ratings from the IIHS (Insurance Institute for Highway Safety) were generally positive. The 2012 GLK-Class earned a "Good" rating in most crash tests. However, it's crucial to check the specific IIHS and NHTSA reports for the 2012 model year for complete and up-to-date information. The available rearview camera significantly aided parking and maneuvering, enhancing overall safety. The optional bi-xenon headlights with adaptive highbeam assist provided improved visibility at night.

Current used market prices range from approximately $8,000 to $15,000, depending on condition, mileage, and options. Depreciation has been significant, as expected for a luxury vehicle. Factors affecting resale value include mileage, condition (both cosmetic and mechanical), service history, and the presence of desirable options packages like the Premium or Multimedia packages.

2012 Mercedes-Benz GLK-Class Insurance

Insurance for a 2012 Mercedes-Benz GLK-Class is moderately priced, reflecting its status as a Sport Utility Vehicle MPV with strong safety ratings and
reasonable repair costs.

How Does the 2012 Mercedes-Benz GLK-Class Compare to Other Sport Utility Vehicle MPV?

The 2012 Mercedes-Benz GLK-Class competes with vehicles like the Audi Q5, BMW X3, and Acura RDX. In terms of performance, the GLK350 offers a strong V6 engine competitive with the Q5 and X3. The Acura RDX provides a similar level of power. Feature-wise, the GLK offers a comparable set of luxury amenities, although its infotainment system can feel dated compared to the Audi Q5. Reliability is generally good, but the Lexus RX (though a size class larger) often outperforms its rivals in long-term dependability. The BMW X3 offers sportier handling, while the Acura RDX provides a more value-oriented proposition. Considering used market prices, the GLK-Class represents a reasonable value proposition compared to its German rivals.

Alternatives to consider include the Acura RDX for its reliability and value, the Audi Q5 for its more modern interior, and the BMW X3 for its sportier driving dynamics. If reliability is the top priority, the Lexus RX (though larger) is a strong contender. The Volvo XC60 offers a stylish and safe alternative.

Final Verdict: Is the 2012 Mercedes-Benz GLK-Class a Good Sport Utility Vehicle MPV?

The 2012 Mercedes-Benz GLK-Class is a good choice for buyers seeking a compact luxury SUV with a distinctive design and a comfortable ride. It's well-suited for individuals or small families who appreciate the Mercedes-Benz brand and don't require a massive cargo area. Whether it's worth buying depends on the price and condition of the specific vehicle. A well-maintained GLK350 with reasonable mileage can represent good value in the used market. Look for models with the Premium and/or Multimedia packages for added features. A pre-purchase inspection by a qualified mechanic is strongly recommended to identify any potential issues before purchase. Avoid neglected examples with incomplete service records.

It’s a really good looking car especially in the pearl

It’s a really good looking car especially in the pearl beige metallic Color and with the golden interior. Its seats are very comfortable and stylish. Only issues are that the car has problems here and there but that’s expected for a car that’s 12 years old. It’s a great starter luxury car!

So far so good . With only 3000 miles.

Nice driver. Really like the style. And the features. It's not Badd on gas if you keep your foot off the pedal. But who wants to do that. Over all I recommend it.

Mercedes affordability

I love my vehicle, words can’t express. I love, love, love, love this suv. This is luxury on a budget, at least for me. I wasn’t the type to buy into make and models. I just wanted to get to where I had to go. My husband and I are in the transition of having college students. I decided to treat myself after paying five years of private school for two. Now mom can indulge, without feeling guilty.

I love my GLK!

I love my car! I've put tons of miles on it and it has performed well! I really love how it handles and the cruise control is by far the best out of any car I've ever driven or owned!

Very Reliable

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.
