Best Mercedes-Benz GLC Model Years (Ranked)
The Mercedes-Benz GLC is the brand's best-selling vehicle globally, a compact luxury SUV that replaced the boxy GLK in 2016 and brought a smoother, more cosseting character to the segment. Across two generations the GLC has offered turbocharged four-cylinders, a high-performance AMG GLC 43 and AMG GLC 63, plug-in hybrids, and the swoopy GLC Coupe body style.
For used buyers, the story is a mix of genuine luxury and a handful of real reliability quirks: early 9G-Tronic transmission software hiccups, 48-volt mild-hybrid electrical gremlins, and infotainment complexity. This ranking covers the strongest GLC model years, their engines, the years to approach with care, and where the smart value lies on the used market today.
Direct Answer
The best overall Mercedes-Benz GLC is the 2020-2022 facelifted first-generation (X253), which pairs a refined turbocharged 2.0-liter four-cylinder, the updated MBUX infotainment system, and a well-sorted nine-speed automatic with the maturity of a platform that had its early bugs worked out.
For shoppers focused on value, the best value is the 2018-2019 GLC 300, offering the same plush ride and strong four-cylinder torque at a notably lower used price after the worst of the launch-year software issues were resolved. Approach the 2016 launch-year cars with caution and verify all recall and service work, and budget for Mercedes maintenance costs regardless of which year you choose.
1. 2020-2022 GLC 300 (X253 Facelift) 🏆 BEST OVERALL
The facelifted first-generation GLC is the sweet spot of the entire range. The 2.0-liter turbocharged four-cylinder was revised to roughly 255 horsepower and paired with a 48-volt mild-hybrid EQ Boost starter-generator, smoothing stop-start operation and adding low-end response.
The big news inside was the MBUX infotainment system with its larger touchscreen, "Hey Mercedes" voice control, and far better usability than the earlier COMAND setup. By this point the 9G-Tronic nine-speed automatic had matured and the platform's early electrical quirks were largely sorted.
With a quiet, supple ride, a genuinely upscale cabin, and available 4MATIC all-wheel drive, the 2020-2022 GLC 300 is the most rounded, low-risk used GLC you can buy.
2. 2018-2019 GLC 300 (X253) 💎 BEST VALUE
The 2018-2019 GLC 300 is the value champion. It uses the 2.0-liter turbocharged four-cylinder (241 hp) with the nine-speed automatic, and by these model years Mercedes had issued software updates that resolved the worst of the launch-period transmission and electrical complaints.
The ride is plush, the interior materials are excellent for the class, and the 4MATIC all-wheel-drive system adds all-weather confidence. The best value is a 2018-2019 GLC 300 4MATIC, which delivers nearly all the substance of the pricier facelift cars at a meaningfully lower used price.
These cars have aged well and represent the smart-money entry into GLC ownership for buyers who can live without MBUX.
3. 2023-2024 GLC 300 (X254, Second Generation)
The second-generation GLC launched for 2023 on the new platform shared with the C-Class. Every version uses a 2.0-liter turbo four with a 48-volt mild-hybrid system, producing about 255 horsepower plus a brief electric boost. The cabin took a major leap with a large portrait MBUX touchscreen, a digital gauge cluster, and improved rear-seat space.
Driving refinement is excellent and the standard 4MATIC all-wheel drive is well calibrated. As the newest and most expensive used option, it carries the longest remaining warranty and the most current technology, but also the shortest reliability track record and the steepest depreciation hit.
A strong pick if your budget reaches a recent example.
4. 2017 GLC 300 (X253)
The 2017 GLC 300 is a strong used buy because it benefited from first-year fixes applied to the 2016 launch cars while still being affordable. It carries the 2.0-liter turbo four (241 hp) and nine-speed automatic, the comfortable ride that defines the model, and a quality interior.
Many 2017 cars received software updates addressing early 9G-Tronic shift-quality complaints. As with all pre-facelift GLCs, the COMAND infotainment now feels dated, and you should verify any open recalls through the VIN. For a buyer who wants the GLC experience at a low entry price and is diligent about service history, a clean 2017 example is a sensible choice.
5. 2020-2022 Mercedes-AMG GLC 43
For buyers who want performance with daily usability, the AMG GLC 43 is the pick. It uses a 3.0-liter biturbo V6 making around 385 horsepower (385 hp in later tune), paired with the AMG SPEEDSHIFT nine-speed and standard performance-tuned 4MATIC. It delivers genuinely quick acceleration and a sharper chassis than the GLC 300 while keeping a usable, comfortable interior.
The V6 is regarded as more robust than the high-strung AMG 63 V8, making the 43 the more sensible AMG for long-term ownership. Expect higher running costs and firmer ride than the standard car, but the GLC 43 offers a compelling blend of speed, sound, and everyday practicality.
6. 2020-2022 GLC 350e Plug-In Hybrid
The GLC 350e plug-in hybrid pairs the 2.0-liter turbo four with an electric motor for a combined output around 315 horsepower and a modest all-electric range useful for short commutes. It retains the GLC's plush ride and luxury cabin while adding the option of quiet electric running and access to HOV or low-emission incentives in some regions.
Buyers should confirm the high-voltage battery health and that the charging system functions correctly, since hybrid components add complexity and repair cost. For a city-focused luxury buyer who can charge at home, a well-maintained 350e offers efficiency gains without sacrificing the GLC's signature comfort.
7. 2017-2019 GLC Coupe (C253)
The GLC Coupe added a sloping roofline and sportier styling to the first-generation lineup. Mechanically it mirrors the standard GLC, using the 2.0-liter turbo four in GLC 300 Coupe form or the V6 in AMG 43 Coupe guise, with the same nine-speed automatic and 4MATIC. The trade-off is reduced rear headroom and a smaller, less practical cargo area in exchange for a more distinctive look.
Reliability mirrors the standard GLC of the same years. For a buyer who values style over outright practicality and likes the coupe-SUV aesthetic, a 2017-2019 GLC Coupe offers the same comfortable mechanicals in a more eye-catching package at a used discount.
8. 2019 Mercedes-AMG GLC 63 / 63 S
The AMG GLC 63 is the range's firebreather, fitting a 4.0-liter biturbo V8 making roughly 469 horsepower, or about 503 horsepower in 63 S trim, with launch-control acceleration that embarrasses most sports cars. It is thrilling and rare, but it is the least sensible long-term used buy in the lineup: the hand-built V8 carries higher maintenance and repair costs, brakes and tires wear quickly, and fuel economy is poor.
Buy one only with comprehensive service documentation and eyes open to the running costs. As an enthusiast toy it is exhilarating; as a daily appliance it is an expensive proposition compared with the GLC 43 or GLC 300.
9. 2016 GLC 300 (X253) — Launch Year (Caution)
The 2016 GLC 300 launched the nameplate and introduced its hallmark comfortable ride and upscale cabin, but as a first-year car it carries the most risk. Early owners reported 9G-Tronic transmission software issues producing hesitant or harsh shifts, along with assorted electrical and infotainment glitches typical of a new platform.
Mercedes addressed many of these through software updates and recalls. Only buy a 2016 GLC with full documentation confirming the transmission and electronic updates were applied. The upside is the lowest used price in the range; the downside is the highest chance of niggling faults.
For most buyers, stepping up to a 2017 or later car is well worth the modest premium.
10. Mercedes-Benz GLK (X204, 2010-2015) — Predecessor
The GLK is the GLC's boxy predecessor and worth knowing for budget buyers cross-shopping older compact Mercedes SUVs. It used a 3.5-liter V6 (GLK 350) and, briefly, a 2.1-liter diesel (GLK 250 BlueTEC), with rear- or all-wheel drive. Styling is upright and angular rather than the GLC's flowing shape, and the interior is less modern.
These are now aging vehicles, so inspect for suspension wear, oil leaks, and the diesel's emissions hardware where applicable. The GLK rides firmer and feels older than any GLC, but a clean, well-maintained V6 example is an affordable way into a durable older Mercedes SUV.
What to Watch For When Buying
The most important step when buying a used GLC is to verify the transmission and electronic software updates, especially on 2016 launch-year cars where early 9G-Tronic shift complaints and infotainment glitches were most common. Run the VIN through Mercedes' recall lookup and the NHTSA database, and confirm any open recalls were completed.
On facelift and second-generation cars, check that the 48-volt mild-hybrid system operates correctly, since its starter-generator and electrical components can be costly to repair. Inspect for the usual luxury-SUV wear: worn suspension bushings and air-suspension components where fitted, oil leaks, and brake condition on AMG models.
For plug-in hybrids, confirm high-voltage battery health and charging function. Above all, budget for Mercedes maintenance costs and favor a car with complete, documented dealer service history over a cheaper, undocumented one.
How to Choose
Match the GLC to your priorities. For the best blend of refinement, technology, and low risk, the 2020-2022 X253 facelift GLC 300 is the answer, with mature mechanicals and the much-improved MBUX system. For the best value, a 2018-2019 GLC 300 4MATIC delivers nearly the same experience at a lower price.
Buyers wanting the newest technology and longest warranty should target a 2023-2024 X254. Enthusiasts should choose the AMG GLC 43 for a sensible performance balance, or the GLC 63 only if they accept the running costs. Budget shoppers can consider the older GLK V6.
In every case, verify recall completion and prioritize a documented maintenance history.
FAQ
Which Mercedes-Benz GLC years should I avoid? The 2016 launch-year GLC carries the most risk due to early 9G-Tronic transmission software issues and infotainment glitches. It is not unbuyable, but only purchase one with documentation confirming the software updates and recalls were completed; a 2017 or later car is the safer choice.
Is the GLC reliable? The GLC is reasonably reliable for a luxury SUV but not class-leading. Expect higher maintenance and repair costs than mainstream brands, and budget for items like the 48-volt mild-hybrid components, suspension parts, and infotainment electronics. A well-documented service history is the best predictor of trouble-free ownership.
What is the difference between the GLC and the older GLK? The GLK (2010-2015) is the GLC's boxy, more angular predecessor that used a 3.5-liter V6. The GLC (2016 onward) introduced a smoother shape, turbocharged four-cylinder engines, a far more comfortable ride, and modern technology including MBUX on later cars.
Which GLC is best for performance? The AMG GLC 43 with its 3.0-liter biturbo V6 (around 385 hp) is the most sensible performance choice, balancing speed and daily usability. The AMG GLC 63 V8 (up to about 503 hp) is faster and more thrilling but far more expensive to own and maintain.
Bottom Line
The Mercedes-Benz GLC is a comfortable, genuinely upscale compact luxury SUV, but model-year choice matters because of early transmission software and electrical quirks. The 2020-2022 X253 facelift GLC 300 is the best overall pick, with mature mechanicals and the improved MBUX system, while the 2018-2019 GLC 300 offers the best value.
Approach the 2016 launch-year cars with caution, choose the AMG GLC 43 over the costlier 63 for performance, and always confirm recall completion through the VIN. Buy carefully, budget for Mercedes upkeep, and the GLC rewards with comfort, refinement, and lasting luxury appeal.
