Mercedes-Benz is renowned for producing superb, luxurious, and highly efficient cars. As one of the oldest automakers in the world, Mercedes has had a lot of time to improve its vehicles. They positioned the company atop the pyramid representing its industry. There is no denying that driving a Mercedes-Benz is enjoyable. Furthermore, they are meticulously created to be robust, dependable, and comfortable.

Like any other car, Mercedes-Benz occasionally experiences problems. Many Mercedes-Benz owners worldwide have been frustrated by several issues with their automobiles. Thus, remember these nine Mercedes-Benz problems and how to avoid them.


9 Most Common Mercedes-Benz Problems

Here are some of the most prevalent problems experienced by Mercedes-Benz owners:


Electrical System Malfunctions

Many Mercedes-Benz models experience electrical issues, ranging from malfunctioning sensors to faulty wiring harnesses. Problems with the electrical system can manifest in various ways, including dashboard warning lights, power window failures, and issues with the central locking system.


Thrust Linkage Bushings Are Known to Crack

For those not car experts, thrust link bushings are parts of a rubber tube on the front axle filled with hydraulic fluid. They are essential to the car’s function and can be fatal if broken. 

These same bushings are known to abruptly crack apart, releasing all the fluid within and spreading it within the Mercedes-Benz, which is why the brand is often linked to disasters. Tire degradation may occur along with a rough ride when the fluid is lost.


Engine Mount Failure

The components that fasten an engine to the chassis of a vehicle are called engine mounts. They are available in a range of sizes and shapes to serve a variety of uses. But they always serve the same purpose: to mount the engine and reduce vibration. Rubber and metal are commonly used to make them. Rubber dampens and absorbs vibrations, and metal is used to endure the tension and torque that the machine produces. An issue involving the engine mounts tends to be noticeable because engines often vibrate when they function. 

The engine mounts on Mercedes-Benz cars made recently are loaded with oil. Unfortunately, it’s been seen that at about 100,000 miles, certain parts start to fail and leak oil. There could be a lot of vibration in the cabin, on the steering wheel, and in the seat if the engine mounts fail.


Reduced Braking Pressure

Most Mercedes-Benz vehicles have a technology called Sensotronic Brake Control (SBC). The SBC facilitates high brake fluid flow, particularly when emergency braking is required. Still, there are situations when the SBC system malfunctions.

Mercedes vehicles frequently experience SBC failures, which result in decreased braking power. The SBC loses efficiency after a certain number of operating cycles and could malfunction while you’re driving.


Engine Misfires

One of the most frequent issues with Mercedes-Benz vehicles is engine misfires. This situation frequently arises in cars that need regular maintenance, especially when replacing worn parts like spark plugs. Regretfully, most owners fail to notice that spark plugs must be changed at the prescribed intervals due to wear and tear. Every 100,000 miles, owners and mechanics in Las Vegas should replace the ignition coils and spark plugs according to manufacturer recommendations.

When one of its cylinders isn’t producing enough power to start the engine, it misfires. It may also occur if the combustion chamber’s fuel-air mixture fails to ignite. You will notice low engine performance when a Mercedes-Benz engine misfires. Additionally, drivers report feeling strange vibrations inside the cabin.

Mercedes-Benz Oil Leak

Oil & Differential Leaks

However, oil leaks in a Mercedes-Benz pose a significantly more serious problem because of the fragility of the electronic transmission system. If your Mercedes was made after 1995, its drivers may have an electronic gearbox susceptible to graphite buildup due to the clutches.

Owners may regularly encounter leaks other than oil ones. Differential leaks have also been problematic for Mercedes-Benz, especially in high-mileage E-class vehicles. These leaks typically result from deteriorating differential covers, axle seals, or pinion seals. Consequently, Mercedes-Benz owners are more likely than owners of most other models to encounter similar issues with their cars.


Air Suspension Failure

Several people have claimed problems with Mercedes-Benz’s AIRMATIC features, although the most prevalent complaint is over the air suspension.

Mercedes-Benz initially introduced air suspension bags in the E-Class W211 and the S-Class W220. Your Mercedes-Benz’s AIRMATIC bags replace the shocks and struts. Regrettably, although it was an excellent feature in certain Mercedes-Benz cars, it was also prone to malfunction. If this issue afflicts your vehicle, you will probably notice uneven tire wear, changing ride heights, and drifting.


Transmission Issues

The 5-speed gearbox of German car brands is more durable than most other automobiles on the market. However, the parts are infamously problematic. Many users report that issues with the transmission valve body and the 13-pin connector worsen the vehicle’s damage.

The 13-pin connector is frequently the source of transmission fluid leak reports. When this fluid leaks into the wiring harness, it destroys the control module. Meanwhile, the valve body could cause bad shifting.


Rusts Quickly and Easily

While it is common knowledge that a regular car can develop rust issues when not in use, Mercedes-Benz vehicles, whether vintage, used, or even brand-new, have a history of rusting out rapidly. The number of areas where rust can appear on a car is even more astounding.

Rust typically occurs under the wheel wells, front fenders, bumpers, under the passenger and driver’s seats, and even behind the license plate.
