Stuff you should know
Here, we’re focuses on the 2015 to 2022 X253 and C253 first-generation Mercedes Benz GLC models (excluding AMG variants). The AMG models, with twin-turbo V6 and V8 engines are considered special vehicles and will be covered separately in their own cheat sheet.
The first-generation underwent a significant update released in September 2019. Body styles include the wagon and a less popular coupe. Initially, in Australia, engine options included a 2.0-L turbo petrol and a 2.1-L twin-turbo diesel, both in various states of tune. In 2017, a 3.0-liter turbo-diesel V6 was introduced. However, with the 2019 update, the diesel options were discontinued. The 2.0-L petrol engine received minor hybrid assistance, and a Plug-in hybrid variant joined the range.
All GLC models use a 9-speed automatic transmission. The majority of used models on the market feature all-wheel drive (4MATIC, as termed by Mercedes), except for the base model GLC200, which is rear-wheel drive.
The model names are defined by the mechanical package, but Mercedes’ extensive range of option packs and accessories adds complexity. Understanding the fitted packs and optional accessories is crucial, as they can significantly impact the price.
While Mercedes Benz positions itself as a premium brand, it’s essential to note that this doesn’t always translate to better build quality or superior reliability. The GLC, in particular, may experience common issues, which will be further discussed below.
What goes wrong
Exterior:
Reports of water leaking into the tailgate, causing leaks from interior panels and reaching the tail lights. This issue is particularly concerning as it may lead to electrical problems.
Instances of water in passenger and driver footwells have been reported, with discussions in forums suggesting various causes such as blocked sunroof drains, sunroof leaks, firewall leaks, or perceived issues with build quality.
Excessive water ingress is known to result in a myriad of electrical issues, and resolving these can incur substantial costs, potentially running into thousands of dollars.
The extensive insulation and underlay beneath the carpet make it challenging to detect water ingress issues until electronic malfunctions occur, leading to potential complications.
Owners have experienced issues with various electronic components, including power mirrors and windows, the powered tailgate, door locks randomly locking or unlocking, and malfunctions in both headlights and taillights.
Fogging up of both head and taillights has been reported, adding to the list of electronic concerns.
Despite being positioned as a premium product, GLC owners report common issues, ranging from water leaks to electronic malfunctions, adding to the overall disappointment. Additionally, spare parts and labor for Mercedes vehicles are noted for commanding significant premiums.
Buyers are advised to thoroughly inspect the GLC for signs of abuse, particularly as original owners may be wealthy but potentially lack driving skill and mechanical sympathy, potentially impacting the vehicle’s overall condition.
Interior:
Owners have encountered issues with various electronic components, including complete failures or glitches in the infotainment system. Some reported cases involve software issues impacting essential functionalities such as the electronic park brake, washer jets, and power-operated seats readjusting randomly.
Certain button functionalities may work intermittently or cease altogether, contributing to a less-than-great user experience.
Some owners have stated that fixing certain electronic issues requires a lengthy ECU firmware update, which can take up to 9 hours. In some cases, this procedure can only be performed at a Mercedes dealership, potentially incurring high costs, especially if the car is out of warranty.
The Artico leather used in the interior has been reported to wear through its colour prematurely, crack, or tear. Warranty coverage for these issues appears to vary among Mercedes dealerships, with some covering the problems under warranty and others not.
Owners have complained about rattles, squeaks, and strange noises emanating from various parts of the interior, including the dash, pillars, and cargo area. Solutions for addressing these issues can often be found in owner groups, providing a sense of community support for troubleshooting.
Mechanically:
2.0-Litre petrol:
Piston failures have become more common, especially in early models (2015-2017).
Turbo issues include vacuum system problems, with no replaceable parts necessitating a complete turbo replacement.
Water pump and coil problems

Piston failures have become more common, especially in early models (2015-2017).
Turbo issues include vacuum system problems, with no replaceable parts necessitating a complete turbo replacement.
Water pump and coil problems are noted, with coils sometimes falling apart during removal.
Common faults with injectors, thermostat, and PCV have been reported, potentially impacting engine performance and reliability.
2.1-litre diesel:
Generally, the diesel engine has proven reliable, with good timing chain performance.
Tensioner wear and occasional issues with injector seals and coolant leaks have been reported.
Common rail diesel-related problems, such as EGR and DPF issues, are also noted for this engine.
3.0-litre V6 diesel:
Issues with the V6 diesel engine are primarily centred around the v-shaped area of the engine.
Turbo problems, including the variable geometry boost actuator causing surging issues, have been reported.
Oil leaks from various components in the v-shaped area, including the intake pipe seal onto the inlet manifold actuator, have been observed.
Oil cooler seal leaks can be misdiagnosed as a leaking rear main oil seal, complicating the identification and resolution of the issue.
Transmission and Driveline:
Regular servicing is recommended to minimise concerns with the transmission and driveline. While there are reports of issues with the 4MATIC four-wheel-drive system, these are not regarded as common faults. Regular maintenance is crucial to preventing potential driveline issues.
Suspension Issues:
Some models (especially GLC300) have been noted to suffer from the suspension hitting bump stops, even over moderate speed humps.
GLCs fitted with air suspension systems may encounter a range of issues, from electronic glitches to problems with the components themselves. However, when functioning correctly, owners praise the performance of the air suspension system.
Fuel Efficiency Complaints:
A number of owners have complained about being unable to achieve the claimed fuel efficiency figures, highlighting a potential discrepancy between real-world performance and manufacturer specifications.
Brake and Tire Issues:
Well-documented complaints about squeaky brakes and tires scrubbing within the wheel arch have been reported. Resolving these issues appears to vary among owners, with some experiencing recurring problems even after fitting new tires or brakes.

Should you buy it?
Deciding on the purchase of a used Mercedes Benz GLC boils down to the priorities you emphasise in your car ownership experience.
If your preferences lean towards image, brand identity, a sense of prestige, and a luxurious driving experience, even if it means compromising on factors like build quality, reliability, value for money, and longevity, then considering the acquisition of a GLC might be worthwhile.
However, this decision should be approached cautiously. It is advisable to opt for a GLC with an impeccable history, subject it to a comprehensive pre-purchase inspection that it successfully passes, and ensure that you possess the financial capacity to maintain and address potential issues.
While the GLC, at its optimal performance, stands out as a superb SUV, a notable concern is shared not only with the GLC but also with other “prestige” brands. These brands often command a premium in both initial purchase and maintenance costs, positioning themselves as superior products. However, as demonstrated time and time again, this premium doesn’t necessarily translate to superior build quality or reliability compared to other mainstream brands.
In the past, esteemed manufacturers like Mercedes Benz were synonymous with crafting premium cars of the highest quality. However, in contemporary times, there appears to be a shift where these manufacturers excel in marketing prowess while not necessarily delivering a superior quality, driving experience, or ownership satisfaction compared to other brands in the market.
