Abnormal noise in is not common. In fact, there are various causes for brake noise, and not every noise indicates a problem with the braking system. Some noises are simply due to weather, temperature, or normal wear and tear and do not signify a fault. More relevant information is as follows: Note 1: If it's a new car, because the brake pads and brake discs are new and still in the break-in period, they may produce a slight hissing sound, which is completely normal. This usually disappears on its own after a few hundred kilometers. If you find that the brake noise persists continuously and cannot be resolved by pressing the brake pedal harder, it is necessary to return to the dealership for inspection promptly, as the brakes are the most critical safety barrier for a vehicle. Note 2: On rainy days or when there is water inside the brake discs, the brake pads and discs may become damp, leading to a noticeable vibration and a humming sound when braking at low speeds. This is normal, and the noise will disappear once the water dries up.

I've been driving a E-Class for over three years, and sometimes I hear some strange noises, especially when going over bumpy roads, but this isn't a common issue. Most Mercedes owners report that the ride is quite quiet, and occasional noises might be due to minor issues like loose interior panels or wear on the sunroof tracks. If you encounter this situation, I suggest first checking if the door seals are aging or if something is rattling in the glove compartment. If that doesn't help, it's best to visit a 4S shop and have a technician diagnose it with professional tools. After all, safety comes first—prolonged strange noises might indicate hidden issues with the chassis or suspension, and addressing them early can save a lot of hassle. Overall, Mercedes-Benz quality is decent, not every car has this issue—it depends on the specific model and maintenance history.

My S-Class has been in use for almost ten years, and I have indeed encountered several instances of abnormal noises, such as creaking sounds when turning, which seem relatively common among older vehicles. According to a mechanic friend of mine, abnormal noises in Mercedes-Benz often stem from aging suspension bushings or wear in the braking system, which are rare in new cars. Paying attention to the frequency and location of the noises while driving can help roughly diagnose the issue. If the noise only occurs at low speeds, it's usually due to loose interior trim; if it's loud at high speeds, it might involve the drive shaft. I recommend having technicians thoroughly inspect rubber components and fasteners during regular maintenance to prevent major issues. Even though it's a premium brand, such minor problems are common as cars age and aren't necessarily systemic issues, so there's no need to worry too much.

I often drive the family's C-Class and feel that unusual noises aren't very common, but certain model years or types like older GLCs might have them. Most of the time, it's minor insignificant noises, such as loose seat bases or air duct resonance. I usually record the sound with my phone and let the repair shop listen to it to avoid unnecessary tinkering. Regular maintenance like cleaning dust from door seams can help reduce noise; overall, Mercedes-Benz has good reliability.

I've worked on quite a few vehicles, and abnormal noises are quite common in high-mileage cars, especially when suspension components or engine mounts age and start making sounds. A simple method is to carefully listen for the source of the noise while driving. If there's a squeaking sound from the chassis area, it's likely the rubber bushings need replacement; if it's a rattling sound from the interior, it could be loose clips. You can check forums to see if others with the same model have shared similar issues, but ultimately, it's best to visit an authorized repair shop for a proper diagnosis with professional equipment—safety comes first. Mercedes-Benz quality isn't bad, but abnormal noises can indeed affect the driving experience. Prevention is better than repair.

Having spent years in car forums, I can say that not every develops abnormal noises, but some users have reported more issues with older or heavily used models like the A-Class chassis. The sources of these noises vary widely—it could be suspension fatigue or minor transmission irregularities, depending on the model and driving habits. I recommend regular vehicle inspections, such as tightening screws and lubricating components every 10,000 kilometers, which can effectively reduce noise. Overall, Mercedes-Benz has fewer abnormal noises compared to other brands, but they shouldn’t be ignored.
