Most Common Problems with Mercedes-Benz Cars

Oct 20, 2022

Many people across the world regard Mercedes-Benz as the king of German automakers because they produce dependable vehicles. Although Mercedes-Benz creates elegant and dependable automobiles, these vehicles are not immune to ordinary automotive problems. Most of these problems can result from poor component design or technological flaws.

Read on to learn some of the common problems that sometimes plague Mercedes-Benz cars.

Engine Mounts

New models of Mercedes-Benz cars have oil-filled engine mounts. Their primary goal is to cut the impact of engine vibrations within the cabin. Since they are oil-filled, they deteriorate and leak the oil at around 100,000 miles. Whenever the engine mounts fail, you might experience significant vibrations on the steering wheel and on the seats.

Reduced Brake Pressure

Sensotronic Brake Control (SBC) is a feature found in most Mercedes-Benz cars. The SBC provides a high brake fluid flow, which is especially beneficial in emergency braking circumstances. However, the SBC system sometimes malfunctions.

The SBC failure in Mercedes cars is a typical occurrence, and it causes cars to have reduced braking power. After a certain number of operation cycles, the SBC loses efficiency and may malfunction while you are on the road.

Engine Misfiring Issues

Engine misfires constitute one of the most prevalent problems that Mercedes-Benz cars face. This is a common occurrence in cars that have not received periodic maintenance to replace components such as ignition coils and spark plugs.

An engine misfire happens when at least a single cylinder cannot turn the engine over with sufficient power. Engine misfiring can also occur when the fuel-air combination inside the combustion chamber cannot ignite. Whenever an engine misfire occurs in a Mercedes-Benz, you will feel odd vibrations in the cabin.

Differential Leaks

Mercedes-Benz cars do have a history of differential leaks. The Mercedes-Benz models most affected are the high-mileage E class series cars. Axle seals, or pinion seals that have degraded over time are to blame for these kinds of leaks. Mercedes-Benz owners are more likely than owners of automobiles from other established brands to encounter these issues.

V12 Runnability Problems

Several Mercedes-Benz V12 engines exhibit unexpected runnability problems, which may manifest as misfires on unusual cylinders and defective O2 sensors. This will trigger the check engine light, which will turn off when you cycle the key again.

The oil leakage from the pressure switch is among the most frequent culprits behind this kind of malfunction. Get a mechanic to change the pressure switch to combat the leakage problem.

Air Suspension Issues

Post-2000, Mercedes-Benz first used air suspension in a few of its models and expanded its use to many more. The technology offers a pretty high-quality ride, although it is not without flaws. Relays and air suspension bags are both susceptible to malfunctions.

If your Mercedes-Benz car has this issue, you'll probably notice abnormal tire wear or uneven ride heights.

Automatic Gearbox Issues

The 13-pin connection and valve body are the weak spots of the Mercedes automatic gearbox. Even though the gear has a strong design, moving into gear may become difficult if the valve's connection or the body fails.

Mercedes-Benz automobiles are dependable and of high quality, but they are also subject to problems that other car brands face. You must be exacting in your efforts to maintain your car and take good care of it. Do not be reluctant to notify your vehicle repair business about your problems.
