Mercedes Benz GLK Years To Avoid

Let’s explore, shedding light on the years to avoid while appreciating the strides this compact crossover brought to the automotive world.

Decoding the First Generation (2010-2012)

The first-generation Mercedes-Benz GLK, spanning from 2010 to 2012, presents a mixed bag of impressions. While the iconic three-pointed star emblem and sharp design lines firmly establish its Mercedes identity, opinions diverge on its overall appeal.

The Car Connection’s assessment reflects this ambivalence, with reviewers split on whether the stiff appearance is a clever move for the brand.

As a compact SUV, the 2010-2012 GLK maintains an unassuming profile that belies its commanding presence.

The juxtaposition of its rugged SUV styling with a compact framework garners attention, as underscored by Car & Driver.

The interior, however, is a point of contention among reviewers. Some admire the vintage squared-off design, while others label it as outdated.

The driving dynamics of the first-generation GLK are commendable, exhibiting car-like performance and balance.

Despite this, the SUV falls short in the fuel economy department, drawing a lackluster rating from Car & Driver. This discrepancy in efficiency sets it apart from its peers in the same category.

Pitfalls and Shortcomings

While the initial GLK generation boasts speed, silence, and agility, its construction reveals chinks in the armor. Premium gasoline is a requirement, the rear seating space is cramped, and certain controls pose challenges.

However, the crux of concern extends to reliability—a cornerstone of any vehicle purchase.

Analyzing previous model performance offers insight into the road ahead. Alas, the first-generation GLK carries a shadow of doubt in this regard.

Consumer Reports’ latest subscriber survey highlights a series of recalls from the National Highway Traffic Safety Administration (NHTSA), underscoring safety concerns.

The recalls, totaling 5 times for the 2010 model, and 4 times each for the 2011 and 2012 models, revolve around critical airbag issues, a paramount concern for driver safety.

The Decision Dilemma

Yet, the first-generation GLK is not entirely devoid of merit. Its inclusion in the avoid list is driven by the absence of safety features abundant in its successor, the second-generation GLK (2013-2015).

The 2010-2012 GLK models trail behind their 2013, 2014, and 2015 counterparts in terms of interior space, safety offerings, and fuel efficiency.

While the U.S. Car News lauds the first-generation GLK with an impressive overall rating of 8.9 out of 10, it’s essential to recognize its limitations.

The allure of newer models cannot be overlooked—enhanced safety, improved interior space, and better fuel efficiency set the stage for a more satisfying ownership experience.

Mercedes Benz GLK Problems

The allure of a Mercedes GLK, standing as a stalwart in the compact luxury crossover realm, comes hand in hand with a set of common problems that discerning owners need to be aware of.

While the GLK proudly represents the “All-terrain Luxury Compact class,” it’s not exempt from facing its share of challenges.

Mercedes Benz GLK Problems

In this section, we delve into the Mercedes Benz GLK problems and explore the common issues that can impact your ownership experience.

1. Auto-up Side Windows Not Working

Among the notable concerns afflicting the Mercedes GLK is the occasional malfunction of its auto-up side windows. Although auto-up window regulators resetting themselves upon battery disconnection is common, the GLK adds an extra layer of annoyance by undergoing this reset randomly.

Thankfully, recalibration is feasible by holding the window button down followed by an upward motion, but this recurrent process can prove vexing to owners.

2. Wind Noise: Unearthing the Culprit

Another challenge reported by some GLK owners revolves around wind noise emanating from the front of the vehicle. This issue left even seasoned Mercedes dealerships puzzled as they attempted to locate the source of the noise.

Ultimately, a technician identified a faulty seal within the heater matrix as the culprit.

The meticulous process of identifying and resolving this issue underscores the complexity of pinpointing problems in luxury vehicles.

3. NOx Sensor Problems: Emissions Dilemma

In diesel GLK models, the inclusion of multiple emission filters, such as the diesel particulate filter and exhaust gas recirculation, presents a potential concern.

The introduction of DEF (Diesel Exhaust Fluid) introduces a new layer of complexity. Issues can arise when the DEF injector fails to deliver sufficient DEF fluid, leading to NOx sensor contamination and triggering the check engine light.

Mercedes’s stringent recommendations regarding diesel fuel and DEF quality further emphasize the need for careful adherence.

4. Ticking Sound From Engine: Navigating the Source

For GLK350 models equipped with the M272DE35 3.5-liter V6 engine, an audible ticking sound originating from the engine bay has been reported.

The initial suspicion pointed to hydraulic valve lifters, a common source of ticking in modern engines.

Dealerships attempted to mitigate this issue by transitioning from 0W-40 Mobile 1 engine oil to 5W-40 Mobile 1, a slightly thicker oil, resulting in resolution.

5. Transfer Case Failure: A Costly Setback

The 2010 model year witnessed a recurring issue in 4matic GLK models, where the transfer case, responsible for distributing power between the front and rear wheels, exhibited signs of failure.

Owners reported shuddering during turns and even loud thuds, indicative of deteriorating clutches within the transfer case.

Although some were fortunate to have these failures addressed under warranty, others faced substantial costs nearing $9,000 for replacements.

Recalls: Seeking Resolution

Recalls offer a glimmer of hope for addressing vehicle issues, yet not all cars receive the necessary attention.

Some owners might opt for DIY fixes or entrust their vehicles to independent mechanics unaware of recalls.

Understanding these recalls becomes paramount for prospective buyers and current owners.

Taking your GLK to an authorized Mercedes-Benz dealer or a reputable mechanic ensures prompt resolution of these problems.

Is a GLK350 reliable?

The Mercedes-Benz GLK350 receives a reliability rating of 3.5 out of 5.0, positioning it 5th out of 11 in the luxury compact SUV category. While its average annual repair cost is $859, which indicates higher-than-average ownership expenses, the likelihood of severe issues is comparatively lower than with other vehicles.

What are the disadvantages of the GLK?

Some of the disadvantages of the GLK include a small backseat and rear doors, limited cargo capacity compared to rivals, and the presence of intrusive wind noise at higher speeds.

What year does GLK stop?

The GLK-Class saw its production run come to an end in 2015. At that point, the model was succeeded by the GLC as part of Mercedes-Benz’s revised nomenclature.

What replaces the Mercedes GLK?

The GLC stepped in to replace the Mercedes GLK, taking over after just five years of the GLK’s production. This transition was part of Mercedes-Benz’s strategic approach to model names and branding.


Delving into the intricacies of the Mercedes Benz GLK reveals a multifaceted landscape. While the GLK boasts impressive attributes, such as its iconic luxury and robust design, it’s essential to acknowledge the common issues that can emerge.

From the occasional annoyance of auto-up side windows not working to the intricate challenges of NOx sensor problems, the GLK’s journey has been punctuated by both strengths and pitfalls.

Wind noise concerns and the ticking sound from the engine underscore the intricacies of luxury vehicle engineering, where even the minutest details can impact the driving experience.

Transfer case failures, though not pervasive, remind us of the complexities of maintaining intricate components over time.

By staying informed about recalls and addressing potential problems promptly, owners can ensure that their GLK remains a reliable and enjoyable companion on the road.

So, as you consider your path forward with a Mercedes GLK, remember to weigh its strengths against its potential pitfalls.
