Mercedes-Benz E-Class common problems and reliability issues

Honest rundown of the most common Mercedes-Benz E-Class faults, what to watch for, and how to keep one running well.

TL;DR

Mercedes-Benz E-Class vehicles are generally reliable but have common issues such as oil leaks in 2010-2015 models, transmission problems in 2009-2016 models, air suspension failures from 2010-2016, and electrical faults across various models. Understanding these issues can help buyers make informed decisions.

Engine Problems

The Mercedes-Benz E-Class is prone to oil leaks, especially in the 2.1-litre diesel engines from 2010 to 2015. These leaks can lead to low oil levels and potential engine damage. Some petrol engines from 2013 onwards may have timing chain issues, risking significant engine failure if not addressed. Earlier models may also experience fuel injector problems, causing rough idling and performance issues.

Transmission Issues

Transmission problems are prevalent in the 7G-Tronic automatic gearbox, particularly in models from 2009 to 2016. Owners report rough shifting and hesitation during gear changes. Regular maintenance, including fluid changes, can help, but buyers should check for signs of trouble. Some have noted faults in the transmission control unit, leading to erratic shifting behaviour.

Suspension Faults

Air suspension failures are common in E-Class models from 2010 to 2016, resulting in a bumpy ride and uneven vehicle height. Replacing air suspension components can be expensive, so a pre-purchase inspection is advisable. Additionally, traditional coil spring setups may experience premature wear and noise over bumps.

Electrical Issues

Electrical faults occur frequently in the E-Class, with issues reported in the central locking system and infotainment glitches across various model years. These can often be fixed with software updates or repairs, but they can be frustrating. Some users have also faced unexpected battery drainage, linked to faulty components or systems that fail to shut down properly.

Known Recalls

The E-Class has had multiple recalls, addressing issues from faulty airbags to braking system problems. Models from 2016 have faced recalls for potential fuel leaks. Checking the vehicle’s recall history is crucial to ensure all necessary repairs have been made. Certain models may also have recalls related to software affecting safety systems.
