The 6 Most Common Mercedes Benz Problems

There are many outstanding features that set Mercedes Benz vehicles apart from other vehicles on the road. Despite the cutting-edge engineering that goes into manufacturing Mercedes Benz vehicles, they do suffer from mechanical problems as well. And when a Mercedes Benz breaks down or experiences issues, these German-made vehicles require special maintenance and repair services to guarantee the best results. 

From years of servicing luxury cars including Mercedes Benz, we’ve observed a pattern of common issues that plague this specific vehicle brand. If you own a Mercedes Benz, here are problems that require immediate attention from a professional auto shop in Sydney.

Engine and Transmission Mounts

Engine and transmission mount failures are prevalent in older Mercedes Benz models. Unlike new models that feature liquid filled transmission and engine mounts, older models were fitted with solid rubber mounts. These vehicle components play an important role in care efficiency and safety, as they are responsible for keeping the engine and transmission properly mounted to the chassis. Additionally, these mounts also prevent vibrations from being transmitted to the passenger cabin. 

One of the most obvious signs of engine and transmission problems is that sudden kick or thumb sensation when gas is applied. In newer models, these problems usually manifest themselves as slow and gradual vibrations in the seat, cabin, and steering wheel. To avoid failure of these two vehicle components, car owners are advised to have their engine and transmission mounts checked every 7 years or after reaching 130,000k kilometre mileage. 

Brake Issues

Mercedes Benz models such as CLS and GL models typically suffer from brake issues. Some of the most common braking issues that our expert mechanics in Sydney have dealt with through the years are as follows:

  • Some CLS owners feel a delay upon releasing the brake. There are also reports of hissing or popping sound upon acceleration. There are also reports that the brakes stick a little. While these braking issues do not affect the overall performance of a car’s braking system, they can cause expensive repairs in the future. These braking issues are known to speed up the wear and rotor warping when left ignored. 
  • In GL models, a contaminated braking system can lead to vibration, reduced braking power, and noise. There are also instances when front brakes produce vibrations due to the accumulation of dust and other particles in the braking system. To resolve this issue, you need the help of Mercedes Benz auto mechanics in Sydney. There are instances when faulty brakes can lead to damaged brake pads and rotors. 

Catalytic Converters

For Mercedes Benz models with more than 8,000 kilometres in it, catalytic converter issues are commonplace. They become less efficient or clogged resulting in the check engine light turning on. When left ignored, the overall performance of a Mercedes Benz is compromised as evidenced by engine misfires and hesitation. In this case, vehicle owners are recommended to seek professional auto mechanic repair for faster resolution

Gear Shift

E and S class Mercedes Benz models are not immune to mechanical faults. Some vehicle owners reveal that their gear shifters won’t come out of the park. Their cars will start and run but the shifter does not change its position. If you experience this issue, it’s best to seek the professional services of a car mechanic in Sydney to check and make the necessary repairs on the selector module. 

Air Suspension and AirMatic Components

The S-Class W220 chassis and more recent E-Class W211 models were the first Mercedes Benz models that utilise AirMatic suspension systems. In these models, the AirMatic suspension system uses air bags in place of regular coil springs. It is installed as a single until with a shock absorber also known as Air Struts controlled by a complex system consisting of pumps, tubing, and valves. For those experiencing errors with their AirMatic components, a simple diagnostic exam is rather expensive compared to checking failures on traditional suspension systems. Air leak is a common issue found in air strut assemblies, but there are also instances when the air pump or control valve suffers from total failure as well.

Steering Components

For Mercedes Benz models older than five years, components such as tie rods, sway bar links, ball joints, and control arm bushings will start showing signs of wear and tear. Since they all play a crucial function- that which is being the anchors of a suspension system, it is easy to tell when they are worn out. When you begin to notice excessive tire wear and tear or steering misalignment, it’s time to seek the professional services of a reputable auto mechanic shop in Sydney that specialises in Mercedes Benz serving and repairs.
