Mercedes-Benz A-Class 2014 to 2019: common problems and what to know

TL;DR

The 2014 to 2019 Mercedes-Benz A-Class has several common issues, particularly with its electrics and gearbox. Potential buyers should be aware of these problems and check for them before purchasing.

Key facts callout

• Common issues include electrical faults and automatic gearbox problems.
• Diesel models are more prone to DPF blockages, especially with short trips.
• The A-Class ranked poorly in reliability surveys, coming 26th out of 31 manufacturers.
• Petrol versions of the A-Class performed slightly better than diesel in reliability rankings.

Engine and gearbox

The A-Class offers a range of engines, from efficient petrol to robust diesel options. However, the dual-clutch automatic gearbox, known as the 7G-DCT, has been a source of concern. Owners frequently report issues such as harsh shifting, slipping gears, and complete failure, particularly in models produced between 2014 and 2019.

Diesel variants are particularly susceptible to Diesel Particulate Filter (DPF) blockages, especially if used for short, stop-start journeys. This can lead to reduced performance and increased emissions, necessitating costly repairs. Regular long drives can help mitigate this issue, but it’s essential to consider your driving habits before purchasing a diesel A-Class.

Electrics and electronics

Electrical problems are among the most reported issues by A-Class owners. Many have experienced malfunctions with the infotainment system, including frozen touchscreens, unresponsive controls, and connectivity issues. These problems can be frustrating and may require software updates or component replacements to resolve.

Additionally, owners have noted issues with the car’s sensors and warning lights, which can sometimes trigger false alerts. While some problems are minor, others may require significant repairs, so it’s essential to check the car’s electrical systems thoroughly before buying.

Body and suspension

The A-Class generally boasts a well-built body and comfortable suspension. However, there have been reports of premature wear on suspension components, particularly in models that have been driven hard or on rough roads. Owners have mentioned issues with noisy suspension and uneven tyre wear, which can indicate underlying problems.

Rust is not a widespread issue, but it’s wise to inspect the bodywork for any signs of corrosion, especially around the wheel arches and undercarriage. Regular maintenance and checks can help keep the A-Class in good condition, but potential buyers should be vigilant.
