What are the Common Problems with Mercedes Cars?

Mercedes-Benz, known for its stunning, luxurious, and high-performance vehicles, is a treat for car lovers. As one of the world's oldest automakers, Mercedes has perfected its vehicles over time, putting the business at the top of the industry pyramid. Undoubtedly, Mercedes-Benz vehicles are a pleasure to drive. In addition, they are meticulously constructed to be comfortable and powerful.

However, they do have problems from time to time, just like any other car. Mercedes-Benz vehicles, too, have disappointed many owners worldwide. You can detect them using a Mercedes diagnostic tool available online. Learn about these six most common problems with Mercedes and ways to fix them. 

Engine mount components secure a vehicle's engine to the chassis. They come in various shapes and sizes to accommodate different purposes. However, they perform the same function of mounting the engine and damping the vibration. Commonly, they are made of metal and rubber. Metal helps to withstand the stress and torque created by the machine. Whereas rubber absorbs and reduces vibrations. As engines produce significant vibration during regular operation, an issue with engine mounts is usually highly noticeable.

Oil-filled engine mounts are used in newer Mercedes-Benz cars. Unfortunately, these components fail and leak oil around the 100,000-mile mark. When the engine mounts fail, you may feel significant vibration in the seat, cabin, and steering wheel.

Engine misfires are very common in Mercedes-Benz vehicles. This scenario often happens to cars without maintenance, particularly replacing wear parts like spark plugs. Unfortunately, most owners overlook that wear-out, which must be replaced at the recommended intervals. 

As per the manufacturer's instructions, owners should change the ignition coils and spark plugs every 100,000 miles. With the help of the Mercedes diagnostic tool, you can know when to change the coils. 

An engine misfire happens when one cylinder does not provide enough power to turn the engine over. It can also occur when the fuel-air mixture in the combustion chamber does not ignite. When an engine misfire happens on a Mercedes car, you may notice poor engine performance. There are even odd vibrations that drivers can feel in the cabin.

If you have a Mercedes manufactured after 1995, it might have an electronic transmission prone to graphite buildup from the clutches. Because of the fragility of the electronic transmission system, an oil leak in the car poses a more severe issue.

Oil leaks are not the only common problems owners encounter. Mercedes-Benz has also been prone to differential leaks, notably in high-mileage vehicles like the E-class series. These leaks are caused by deterioration of the axle seals, pinion seals, or differential covers over time. As a result, owners are more prone to experience these problems than car drivers from most other brands.

There are several issues with Mercedes-Benz cars, but the most common complaint is air suspension. The E-Class W211 and S-Class W220 were the first Mercedes cars to feature air suspension. The AIRMATIC bags were designed to replace the struts and shocks. 

Unfortunately, the feature was incorporated into some Mercedes-Benz vehicles, but it was also prone to failure. If your car is affected by this problem, you will likely notice altered ride heights, drifting, and uneven tire wear.

The Mercedes has a more robust 5-speed transmission than most vehicles. However, the components are problematic. Many users report issues with the 13-pin connector and the transmission's valve body, causing more damage to the vehicle.

Transmission fluid leaks are quite common with a 13-pin connector. The fluid flows into the wiring harness, damaging the control module. Meanwhile, the valve body causes poor shifting.

We all know the average car is prone to rust when not utilized. However,  Mercedes-Benz is known for quickly rusting out on older and newer cars. Even more surprising is the number of spots where rust can appear on the car. Common rust-prone areas are 

• beneath the wheel wells
• on the bumpers
• along the floorboards,
• front fenders
• underneath the driver and passenger seat
