Common Problems With Mercedes Benz Cars

Mercedes Benz is one of the most prestigious car brands in the world. This German automobile line has been around since the early part of the 20th century which is long before the Patriots and Warriors began to upset fans of their respected leagues.

Mercedes cars are known for their stylish and luxurious designs, innovative engineering, excellent performance, and top-class safety features. It is a thing of pride to own a Mercedes.

There is a status symbol attached to this brand. With that said, Mercedes cars are not immune to faults.

The kind of issues you’ll have with your Mercedes depends on several factors like the condition of the car.

Regular maintenance is necessary to prolong the lifespan of your Mercedes and keep it road-worthy. It is easy to overlook maintenance if there are no apparent issues with your car. However, this is the wrong approach.

There is no hard rule when it comes to the regularity of running maintenance on your Mercedes.

Generally, it is advisable to have your Mercedes serviced after every 10,000 miles or every 12 months.

However, newer models may be able to stay for up to two years or 20,000 miles before servicing. With that said, let’s look at some of the most common problems that affect Mercedes rides.

RUSTING 

Although it may seem like something trivial compared to problems that affect your car’s functionality, Mercedes automobiles are prone to rust. Older Mercedes models like the 240D are known to experience this more than newer models.

Rusting on cars is caused by a chemical reaction between the metal and air or water.

Rust can reduce the value of your car if you plan to resell it. It is essential to look out for signs of rusting on your car quickly before it sets in. Otherwise, it will be costly to repair.

You are likely to spot rusting at the bottom of doors as well as above your tires, and behind your license plate.

There are many ways to deal with rust on cars. For the best results, it is advisable to consult a professional. A stellar auto shop can restore your car looking as good as new.

STEERING ISSUES 

Both new and old Mercedes models are prone to having problems with their steering components. The 2011 Mercedes C-Class is particularly susceptible to this.

You may start to notice problems with this issue after a few years or after 60,000 to 100,000 miles.

Problems with the steering and suspension components of your car may manifest in different ways, including leaking brake fluid or misaligned wheels.

If you are experiencing any malfunction with the steering of your Mercedes, it is essential to have it checked by an automobile expert. Usually, the solution to this involves replacing the steering and suspension components.

However, that is not always the case. It may take only a few hours for your car to be fixed.

ENGINE AND TRANSMISSION MOUNT ISSUES 

Another common problem with Mercedes cars has to do with engine and transmission mounts. The mounts of newer Mercedes models are filled with hydraulic fluid. In older models, they are made of rubber.

These mounts are designed to absorb vibrations from the engine, so the passenger does not feel it. After about 100,00 miles, the engine mounts may start leaking oil or the plastic breaks apart.

You will feel heavy vibrations in your car seat and steering wheel when your engine and transmission mount is faulty. You may also see fluid leaking or feel your car jolt whenever you accelerate.

Unlike other car parts, engine, and transmission mounts cannot be repaired. They can only be replaced if they are faulty. If you notice that your engine and transmission mount is failing, take your car to a trustworthy mechanic as soon as possible.

It usually takes about 4 to 6 hours for your engine and transmission mount to be changed which is about as much time as it takes to watch two amazing Michael Bay Transformers movies or two Fast and Furious movies.

Thankfully, in new and old Mercedes models, it takes up to 100,000 miles before you will start to experience issues with your engine and transmission mount.

WHEEL BEARING ISSUES 

A wheel bearing is made of a metal ring which contains a set of steel balls. The function of the wheel bearing is to help your tires spin without any friction.

Some high-performance Mercedes models like the V8 and V12 are known to experience wheel bearing issues frequently.

One of the easiest ways to tell that your vehicle’s wheel bearing is not in a good state is that you will hear a noise whenever you make a turn – it could be humming or scratching. The sound may be loud or subtle. You may also feel a vibration in your steering wheel.

It should be noted that Mercedes makes some of the best wheel bearings on the market. As indicated above, wheel bearing issues are limited to some Mercedes models, particularly those that are heavy and put a lot of pressure on the wheels. Also, you are unlikely to notice it until after 90,000 to 100,000 miles.

Apart from the weight of the car, the wheel bearing could also be affected by rust if dirt and water get into it.

It is not expensive to replace the wheel bearing of a Mercedes, and the task only takes about two hours. However, it must be done by an expert mechanic.

AIR SUSPENSION 

Mercedes cars such as the Airmatic, E-Class W211, and S-Class W220 come with an air suspension system. Although Mercedes’ air suspension is renowned for providing a smooth ride, it is also prone to issues.

Usually, it is easy to tell when there is a problem with your car’s air suspension because you will receive a notification on the dashboard.

The most common issues with Mercedes’ air suspension system include a faulty air compressor, leaks, a damaged fuse or valve issues.

The symptoms of problems with your car’s air suspension include sagging at the rear section of your car, the front of your car dropping low whenever you come to a stop, and a bouncy ride.

Air suspension issues may not affect your ability to move your car around, but it poses serious safety concerns. It can affect your ability to control the vehicle and make you prone to accidents.

It can be expensive to repair faults with your Mercedes car’s air suspension. However, the sooner you have it diagnosed by any expert auto technician, the better the chances of fixing the problem without extensive work. Just don’t have anyone work on your car who’s named Jake Harper from Two in a Half Men – that’s a risk you don’t want to take.

CHECK ENGING LIGHT REMAINS ACTIVATED 

If you notice that the check engine light on your Mercedes dashboard remains on, there is a concrete chance that there is an issue with your car engine and you need to have it checked out. However, sometimes, it may be due to other reasons.

For example, your gas cap may be open. It may also be due to an issue with your oxygen sensor, catalytic converter, mass airflow sensor, or spark plug.

If you notice that the check engine light on your dashboard is activated and you are sure it is not an open gas cap, then take your car to an auto shop to have it serviced.

All the potential issues listed above may have a serious effect on the performance of your vehicle. Therefore, you need to have your Mercedes diagnosed as soon as possible.

WINDOW REGULATOR 

Some Mercedes models like the ML-Class and C-Class are known to suffer from window regulator issues. These cars use power windows instead of manual windows. Several factors may affect the functionality of your window regulator.

The symptoms if a failure with the window regulator of your Mercedes include noises when you are winding the window up or down, the window getting stuck, the window control button doesn’t work, or the window goes up/down very slowly.

If you notice any of these issues with your car window, it is essential to have it checked as soon as possible. A faulty window may lead to damages to the internal components of your car.

Therefore, it is crucial to have it fixed as quickly as possible. Thankfully, it is not very expensive to repair window regulator problems. However, you must ensure it is done by an experienced mechanic.

THE FUNDAMENTALS 

These are just some of the common problems with Mercedes cars. Some other less popular issues that may affect Mercedes cars include transmission problems, misfires and ignition faults, gear shift getting stuck, the car failing to start, climate control failure, and even braking issues.
