What Is the Mercedes-Benz GLA?
Definition, History & Overview of the GLA-Class
The Mercedes-Benz GLA (Gran Luxury Automobile) is a compact luxury SUV/crossover produced by the German automaker Mercedes-Benz. It was introduced to the market in 2014 as the brand’s entry-level SUV, positioned below the larger GLC, GLE, and GLS models in the lineup. Built on the MFA (Modular Front Architecture) platform — shared with the A-Class and CLA-Class — the GLA was designed to combine the elevated ride height and sporty aesthetic of an SUV with the agility of a compact hatchback.
The Mercedes-Benz GLA-Class spans two generations. The first generation (X156) ran from 2014 through 2020, offering a 2.0-litre turbocharged four-cylinder engine, available in both front-wheel drive and 4MATIC all-wheel drive. The second generation (H247), launched for the 2021 model year, brought a completely redesigned interior, a longer wheelbase for more passenger space, and the brand’s flagship MBUX infotainment system.

Common Problems with the Mercedes-Benz GLA
What issues to look for — regardless of model year — before buying a used GLA
Most prevalent in the 2017 model. Brakes can give out and require a complete system replacement costing $1,000–$3,000.

Specific to vehicles built between July–September 2015. Affected units require dealer-installed camshaft replacement.
Some 2015 vehicles and specific 2014–2017 build dates may have front passenger airbag deployment issues. Check for open recalls.
Some vehicles equipped with panoramic sunroofs may not have the front roof panel bonded correctly. Mercedes issued a recall for this issue across multiple models including the GLA.
COMAND infotainment system can freeze or reboot in older models. MBUX in Gen 2 can suffer minor software bugs but generally updates well.
As a luxury brand, Mercedes-Benz parts and labor are above-average in cost. Annual maintenance can run $900–$1,400 vs. $500–$700 for non-luxury competitors.
Is the Mercedes-Benz GLA Safe?

How to Buy the Right Mercedes-Benz GLA
Step-by-step guide to purchasing the best-value, most reliable used GLA
Step 1: Set Your Budget
Used GLA250s from 2016–2020 range from approximately $8,000 to $21,000. The 2019–2020 hits a sweet spot of about $14,000–$21,000 for best value. Budget an additional $1,000–$2,000 for a pre-purchase inspection and any minor servicing needed.
Step 2: Focus on the Right Years
Target 2016, 2019, or 2020 model years. Strictly avoid the 2017 unless you have a full professional inspection confirming the brake system is intact and all recalls are completed.
Step 3: Check the NHTSA Recall Database
Visit nhtsa.gov/recalls and enter the VIN of any GLA you’re considering. Verify all open recalls — especially airbag, brake, and sunroof-related ones — have been completed by a dealer.
Step 4: Get a Vehicle History Report
Use Carfax or AutoCheck to check for accident history, number of owners, service records, odometer fraud, and title issues. Prefer vehicles with full service history at Mercedes-Benz dealerships.
Step 5: Pre-Purchase Inspection
Have a certified Mercedes-Benz mechanic inspect the vehicle. Pay particular attention to the brake system, transmission shifting quality, electrics, and suspension. This $150–$200 inspection can save thousands in repair costs.
Step 6: Test Drive & Negotiate
Test drive at highway speed, in slow city traffic, and through a parking maneuver. Brakes should feel firm and consistent. The dual-clutch transmission should shift smoothly. If anything feels off, walk away or negotiate a significant discount to cover repair costs.

Frequently Asked Questions (FAQ)
Most common questions about the Mercedes-Benz GLA best and worst years — answered by our experts
The best years for the Mercedes-Benz GLA are 2016, 2019, and 2020. These model years have the fewest reported complaints and highest owner satisfaction. The 2020 GLA250 is considered the top pick among first-generation models, earning a 10/10 safety score and 9/10 across design, performance, fuel efficiency, and infotainment. If budget allows, the 2021+ second-generation GLA is the most modern and feature-rich option.
The 2017 Mercedes-Benz GLA is the worst model year, with significant brake system failures documented as the primary complaint. The 2015 GLA is a close second with the highest total complaint count (~85 complaints), including airbag, camshaft, and powertrain issues. The 2018 is also a cautionary year due to transmission troubles and spark plug errors.
The 2017 GLA should be avoided because it has the highest number of complaints among all model years, dominated by severe brake system failures. The brakes on these vehicles can give out unexpectedly and may require a complete brake system replacement, which can cost $1,000–$3,000+. This is not just a financial risk — it’s a direct safety hazard that makes the 2017 the most dangerous year to buy used.
A well-maintained Mercedes-Benz GLA engine can last approximately 200,000 to 250,000 miles. This is a solid lifespan for a compact luxury SUV. The key factors affecting longevity include following Mercedes’ recommended service intervals, using the correct specification oil and fluids, addressing minor issues early, and avoiding the more problematic model years that may have underlying mechanical problems.
Overall, the Mercedes-Benz GLA is a reasonably reliable luxury compact SUV, particularly in the 2016, 2019, and 2020 model years. The What Car? 2023 used car reliability survey gave the first-generation GLA a 94.1% reliability score, placing it third among most reliable used family SUVs. However, Mercedes as a brand scored lower overall (75.1% — 27th out of 30 brands), so year-specific due diligence is essential.
The most common problems include: (1) Brake system failures — primarily in 2017; (2) Transmission troubles — dual-clutch jerking in 2015 and 2018; (3) Spark plug errors — mainly 2018; (4) Camshaft failure — specific build dates in 2015; (5) Airbag deployment issues — certain 2014–2017 build dates; (6) Electrical/software glitches — across multiple years; and (7) Panoramic sunroof bonding defects — covered under recall across multiple Mercedes models.
Yes, the Mercedes-Benz GLA is worth buying — provided you choose the right model year. It is a fun, sporty, premium compact SUV that many owners love for its driving dynamics, quality interior, and brand prestige. Stick to the 2016, 2019, or 2020 versions for the best ownership experience. Avoid the 2017 and 2015. If you can afford a Gen 2 (2021+), it’s the most complete and modern version of the GLA available.
The GLA 250 FWD (front-wheel drive) is lighter, marginally more fuel-efficient (~27 mpg combined), and less expensive. The GLA 250 4MATIC AWD adds Mercedes’ all-wheel drive system for better traction in snow, rain, or loose surfaces. The AWD adds approximately $2,000–$3,000 to the purchase price. For drivers in cold climates or areas with significant rainfall, the 4MATIC is strongly recommended. The FWD is adequate for mild weather and mostly urban driving.
Annual maintenance costs for the Mercedes-Benz GLA typically run $900–$1,400 per year, compared to $500–$700 for non-luxury compact SUVs. Major service intervals (spark plugs, transmission service, brake fluid) add additional costs. Brake replacement on problem years can cost $1,000–$3,000. Premium fuel is required. Buying a Certified Pre-Owned (CPO) GLA from a Mercedes dealer can reduce unexpected repair costs with included warranty coverage.
The Mercedes-Benz GLA was fully redesigned for the 2021 model year (second generation, codenamed H247). The redesign brought a longer wheelbase for more rear legroom, a completely revamped interior with the MBUX dual-screen infotainment system, updated exterior styling, improved safety technology, and a mild performance boost to 221 hp for the base GLA 250. The second generation is widely regarded as a significant improvement over the first-generation X156.
