Proceed with caution
2016 Mercedes-Benz Gla
While offering an appealing taste of luxury at an approachable price point, the 2016 Mercedes-Benz GLA requires diligent maintenance and a healthy awareness of its common electrical and powertrain vulnerabilities. This vehicle is not a set-it-and-forget-it proposition, demanding proactive ownership and a dedicated repair budget to ensure a satisfactory experience.
Why this year scores low
The GLA is prone to various electrical gremlins, including infotainment system freezes/reboots, sensor failures (e.g., ABS wheel speed sensors, NOx sensors), parasitic battery drains, and issues with power accessories. Diagnosis is often time-consuming and expensive.
Many owners report harsh shifts, hesitation, clunking, or shuddering, particularly at low speeds or during initial acceleration. These issues can range from software glitches to costly mechatronic unit failures, making for a less-than-smooth driving experience.
The M270/M274 2.0L turbocharged engine is known for developing oil leaks from the valve cover gasket and sometimes the front timing cover or cam plugs. PCV (Positive Crankcase Ventilation) valve failures are also common, leading to increased oil consumption or smoke.
