Although they also make hatchbacks, SUVs and trucks, the one style of car Mercedes is most known for is their executive saloons. The E-Class is their mid-size saloon, which competes with the BMW 5 Series and Audi A6. 

Mercedes has a reputation for being well-engineered and made, with older models being used the world over as taxis for decades - but does the new E-Class live up to this hype?

Is the Mercedes E-Class Reliable?

After finishing 3rd place in WhatCar?’s reliability survey for luxury vehicles, you would think the E-Class is pretty reliable; however, the brand as a whole finished 24th out of 31. This may be due to the type of cars it was up against in the luxury car class, compared to the likes of Toyota and Honda in the general category.

Mercedes E-Class Recalls

Recalls are made to fix a manufacturing or design fault that was picked up after the cars had been sold. This requires the owners to bring them back to the dealership, for the remedial work to be done. 

Recall work is not charged to the owner of the car, and is paid for by the manufacturer. To check if your car has outstanding recalls, visit the government recall checker.

12v Battery may not remain secure in a crash

The 12v battery on the current generation of E-Class is secured by a fixing strap, and is located in the boot. Some models were fitted with an insufficient attachment method, causing the battery to become unsecure. 

The fix is relatively simple, requiring an additional fixation being attached to the battery, which would be done free of charge at a Mercedes dealer. This fault affected around 3,600 cars.

Wiring harness recalls

In 4 separate recalls, spanning from 2022 to 2024, multiple issues were detected with the attachment of the wiring harness to the body of the car.

In total this affected around 3,500 cars. However, because they are issued on separate recalls it is difficult to tell if some cars will be affected by the same recall notices. 

As you'd expect, the recall work involves simply fixing the wiring connectors and clips to make sure they are up to specification. As the wiring will be either under the car or buried behind many interior trim panels, expect the dealer to need your car for a few days at least.

Mercedes E-Class Common Issues

Exhaust sensor

Numerous owners have complained of a similar issue, causing an engine warning light on the dash, and in extreme cases a limp-home activation. In this case these were caused by a faulty sensor in the exhaust system. 

It is likely this was a lambda sensor, something that reads the oxygen level in the exhaust gases, something that is vital for the ECU to understand how well the engine is running. A faulty lambda sensor is likely to cause error codes. 

Air suspension system

To give an incredibly smooth yet dynamic ride, certain trim levels of the E-class are fitted with air suspension. This is not a new thing in the world of luxury cars, but it almost always becomes a bone of contention, especially as the cars get older. 

Issues arise when the system begins leaking or malfunctioning, which can result in a harsh, uncomfortable ride and sometimes require immediate attention. Whilst most W213 models (the current generation) are unlikely to experience major faults, it is something that adds complexity.

Electrical issues

Ranging from transmission ECU problems, infotainment issues, and general wiring niggles, there are a few instances of owners requiring extensive work under warranty to repair electrical problems. 

It’s unclear if these things are related to the wiring recalls listed above or are just a symptom of cars being more and more complex nowadays.

Is the Mercedes E-Class Worth It?

The market for executive saloons is well stocked, with options from Audi, BMW and Lexus, but Mercedes is probably the first port of call for most. Therefore, if you’re looking for something that gives a certain impression, the above issues are probably not much to worry about, especially if your car will still be under warranty. 

That last point, the car being under warranty, is something I would not overlook. With Mercedes dealer repairs being some of the most expensive, you’ll certainly not want to be fixing major issues out of your own pocket.
