The best Mercedes-Benz GLA years are 2020 and the 2022 through 2024 model years. Buyers should avoid the 2015 and 2019 models due to high recall counts and severe transmission control issues.
These rankings are comparative, as no luxury subcompact SUV is entirely flawless. Proper maintenance history and a thorough pre-purchase inspection remain essential for any used vehicle.
Significant differences exist between the first and second generations. The earlier models use a seven-speed dual-clutch transmission, while newer versions feature an updated eight-speed unit and revised infotainment systems.

How We Evaluated the Mercedes-Benz GLA Model Years
Our analysis considers official NHTSA recalls, manufacturer service campaigns, and consumer complaint patterns across the broader Mercedes Benz lineup. We evaluate powertrain differences, generation changes, and repair complexity.
Complaints are not confirmed failure rates, and a recall does not automatically ruin a vehicle’s reputation. Recent models have limited long-term exposure, meaning our top picks represent comparatively stronger options rather than flawless guarantees.
Best Mercedes-Benz GLA Years
2020 (Best Older Choice)
The 2020 model year represents the final iteration of the first generation. Mercedes-Benz had resolved most early production issues by this point. The powertrain is mature, and the infotainment system is more stable than earlier versions.
2022-2024 (Best Late-Generation Choice)
These second-generation years benefit from the updated MFA2 platform and the eight-speed dual-clutch transmission. They show very low complaint volumes and benefit from modern safety technology. Long-term durability is still being established, but current data is highly favorable.
Best Year by Buyer Type
Best Overall
The 2023 model year combines the refined second-generation platform with established reliability and modern MBUX features.
Best Budget Option
The 2016 model year avoids the first-year pitfalls of the 2015 launch while remaining highly affordable on the used market.
Best Modern Alternative
Buyers needing more rear-seat space should consider the boxier GLB, which shares related architecture but offers optional three-row seating.
Years to Approach Carefully
2016, 2017, and 2018 (Approach Carefully / Good With Inspection)
These middle first-generation years are generally acceptable but require vigilance. The 2017 model has higher reports of premature brake wear. The 2018 model year has documented instances of the transmission unexpectedly shifting into neutral.
2021 (Good With Inspection)
As the first year of the second generation, the 2021 model introduced the new MBUX infotainment system. Some owners report software glitches that typically require dealer software updates to resolve completely.
Worst Mercedes-Benz GLA Years
2015 (Avoid)
The launch year of the GLA suffered from typical first-year growing pains. Owners frequently report low-speed shudder from the seven-speed dual-clutch transmission and premature engine mount failures. It also carries multiple safety recalls.
2019 (Avoid)
The 2019 model year stands out for an unusually high number of NHTSA recalls. Critical issues include transmission control unit failures that can cause the vehicle to shift into neutral while driving.
Mercedes-Benz GLA Reliability by Generation
First Generation (2015-2020)
Built on the MFA platform, this generation shares related architecture with the Mercedes-Benz CLA. The primary reliability concern is the 7G-DCT transmission, which can exhibit mechatronic failures and low-speed hesitation. Engine mount deterioration is also common.
Second Generation (2021-Present)
The H247 generation moved to the MFA2 platform and introduced an eight-speed dual-clutch transmission. This updated gearbox is significantly smoother and more reliable. The interior technology is vastly superior, though early software versions required debugging.
Common Mercedes-Benz GLA Problems
Transmission Shudder and Mechatronic Failures
First-generation models equipped with the 7G-DCT transmission may experience shuddering during low-speed acceleration or hesitation when pulling away from a stop. In severe cases, the mechatronic unit fails, requiring an expensive replacement.
Engine Mount Deterioration
The hydraulic engine mounts on early turbocharged models can collapse prematurely. This leads to excessive cabin vibration, harshness during idle, and clunking noises when shifting gears.
Electrical and Infotainment Glitches
Owners across multiple generations report intermittent electrical faults. First-generation models struggle with backup camera failures, while second-generation owners occasionally face MBUX screen freezes that require a system reboot or dealer software update.
What to Check Before Buying a Used Mercedes-Benz GLA
- Verify the VIN for any open NHTSA recalls, especially regarding the transmission control unit and airbags.
- Test the transmission extensively in stop-and-go traffic to check for shuddering or hesitation.
- Inspect the engine mounts for sagging or collapsed rubber by observing engine movement during revs.
- Ensure all MBUX infotainment features, including the dual screens and voice control, function without freezing.
- Check for premature brake rotor wear and uneven pad deposition on 2017 and 2018 models.
- Arrange an independent pre-purchase inspection with a European automotive specialist.

Why should I avoid the 2019 Mercedes-Benz GLA?
The 2019 model year is subject to an unusually high volume of NHTSA recalls. Critical campaigns involve transmission control unit defects that can cause the vehicle to unexpectedly shift into neutral while driving.
Does the Mercedes-Benz GLA have transmission problems?
First-generation models with the seven-speed dual-clutch transmission frequently exhibit low-speed shudder and mechatronic failures. The second generation uses an improved eight-speed unit that largely resolves these issues.
Is the 2015 Mercedes-Benz GLA a good used buy?
No, the 2015 launch year is best avoided. It suffers from early production defects, including premature engine mount failures, transmission hesitation, and multiple open safety recalls.
