TL;DR

The Mercedes-Benz E-Class is generally reliable, but its dependability varies by model year. The 2014-2016 models are more reliable, while the 2010-2012 models have higher failure rates and common faults. Key issues include electrical faults and air suspension failures, which can lead to costly repairs.

MOT Pass Rates

MOT pass rates for the Mercedes-Benz E-Class show a mixed picture. According to DVSA data, the 2010-2012 models have a higher failure rate, often due to issues with lights, brakes, and emissions. In contrast, the 2014-2016 models have improved significantly, with pass rates closer to 80%. This improvement reflects enhancements in manufacturing and design that have addressed many of the earlier issues.

Common Failure Modes

Several common faults have been reported across various model years. Electrical issues, particularly with the infotainment system, are frequently noted. Owners have pointed out that the system can freeze or fail to respond, which can be frustrating. Air suspension failures are also common, especially in models equipped with this feature. Additionally, turbocharger problems can arise in diesel variants, especially in the 2012-2014 range, leading to performance issues and increased repair costs.

Buyers in UK communities have flagged that the 2013 model year is also a mixed bag, with some owners experiencing fewer issues compared to its predecessors.

Maintenance Costs

Maintaining a Mercedes-Benz E-Class can be costly. Routine services are generally higher than average, and specific repairs can be expensive.
