Are Mercedes Reliable Cars? Everything Mercedes Owners Should Know

It’s not uncommon to find concerns on Reddit and owners forums about Mercedes cars’ higher maintenance costs compared to other brands like Toyota. But does this mean that they are unreliable, or are Mercedes reliable cars?

This guide contains everything you need to know as a Mercedes owner, including known issues and some tips on how to fix any problems. However, for more detailed explanations and information, you can reach out to our team of specialists at Hofmann’s of Henley.

What Should Mercedes Owners And Buyers Check On Their Car?

Mercedes-Benz has had a mixed reputation for reliability. Generally considered to be luxurious and reliable, Mercedes brands itself as the epitome of high-class German engineering. 

But their cars are not without issues. For example, the early 2000s, in particular, saw many cars have issues. Major electronics issues, mostly brought about by new technologies, were common, along with more mechanical faults, like air suspension problems. However, aside from these issues that were common in the 00s, Mercedes cars are well-built and undergo rigorous testing during development.

What are common faults in Mercedes?

Here is a list of Mercedes-specific issues that you should keep an eye out for when buying and owning a Mercedes-Benz:

1. Engine Mounts

To dampen engine vibrations, Mercedes uses oil-filled mounts in the newer models. Although this helps to ensure a smoother ride, the mounts can fail and leak oil, which causes significant vibrations throughout the car. It makes it extremely unpleasant to drive.  

This will most likely become an issue around 100k miles but can occur earlier. So, if you have a newer model Mercedes or are looking to buy one around this mileage, check the mounts for signs of oil leaks. 

2. Air Suspension

The air suspension system in modern Mercedes cars are prone to perishing seals and gaskets. Failure can cause drifting, uneven tyre wear, and altering ride heights, which often come with expensive repair bills.

This is one of several issues reported with Mercedes AIRMATIC cars. If you own or are buying a car with this feature, have someone look over the air suspension. 

3. Engine Misfires

One of the most common problems with Mercedes cars is engine misfires. This is often caused by lack of maintenance rather than a manufacturing issue however. 

So check that any car you own or buy is regularly serviced, including oil and filter changes as well as spark plug replacement at the necessary intervals. 

4. Gear Box 

Newer Mercedes models have a sophisticated gearbox, which is very efficient. The 7G-Tronic gearbox allows for fast and smooth gear changes but requires regular maintenance and services. 

If the gearbox isn’t serviced regularly, it is prone to damage. So as a Mercedes owner, you should schedule gearbox services in. Or if you are buying a used-Mercedes, make sure the previous owners maintained the gearbox. 

5. Brake Hose

The brake hose to the rear was too short on newer Mercedes A-Class models. This caused strain on connections, ultimately risking braking failure. 

This issue only affected A Class manufactured after March 2018. Mercedes issues a recall for this fault, so check to see whether your car has been fixed. This is 

6. Software Updates

Particularly affecting C Class models from 2014-2018, Mercedes recalled some cars due to a software issue that caused poor fuel economy. 

This was primarily 1.6 diesel C-Class cars, but you can check to see if your car was affected here.

Should I Buy a Mercedes-Benz?

Yes! Mechanical issues can affect all cars, and Mercedes-Benzes are no different. However, if they are regularly serviced and maintained, they are generally reliable. 

If you own a Mercedes or are thinking about purchasing one, it’s important to be aware of any specific issues related to the model you’re interested in. For example, make sure you check if Mercedes issues any recalls for the car and that any necessary work was completed. Also, it’s important to know the service history of your vehicle as regular maintenance is essential in keeping your car in the best condition mechanically and aesthetically.
