Why is there a noise in the Mercedes-Benz GLK door?
4 Answers
It may be due to component issues. The noise from components could be caused by loose screws, assembly problems, or issues with soundproofing materials. Component damage: Simple issues can be resolved manually, but it is best to have it inspected and repaired at a 4S shop. Possible long-term use components: The door is a frequently used component over time. The door seals may harden, increasing friction and causing noise. If the car shakes, it is prone to produce noise. If the door lock pillar is misaligned, causing the door to not fit tightly with the body and produce noise, the door lock pillar needs to be adjusted until it fits tightly with the body.
I've been driving a Mercedes-Benz GLK for several years, and door squeaking is quite common, mostly caused by wear or looseness in the door hinges. Over time, frequent opening and closing of the doors can loosen the hinge screws, resulting in creaking sounds. I recommend first checking the hinge area and applying some lubricant, such as WD-40, for temporary relief. Another possibility is misalignment in the door lock mechanism, where the latch rubs against the body, causing noise—this requires realignment. Internal components like window regulators or loose interior panel clips can also produce rattling sounds on bumpy roads. Additionally, poor air sealing due to aged or deformed door seals can cause wind noise at high speeds, affecting the driving experience. If these minor issues aren't addressed promptly, they may escalate into seal failure or difficulty closing the door properly. It's best to schedule regular comprehensive maintenance at an authorized dealership.
When encountering squeaky doors on a Mercedes GLK, I believe aging seals are the primary culprit. Prolonged exposure to sunlight and rain can cause the rubber door seals to dry out, crack, and deform, resulting in friction against metal components when opening or closing the doors. I often clean the seals with a damp cloth and apply a bit of petroleum jelly for maintenance, which helps reduce the noise. Loose screws in the window regulator can also be a cause; you can check for loose trim panels by gently pushing and pressing to identify the issue. Additionally, parking on uneven ground for extended periods can cause slight door deformation, leading to squeaks—so pay attention to parking spots. If the noise is more noticeable at high speeds, it’s definitely a wind noise issue, as poorly sealed seals allow turbulent airflow. Ignoring these issues isn’t just annoying—it can also lead to increased fuel consumption or water leakage. Addressing them early saves money and hassle.
Door rattles are quite common on the GLK, and I've dealt with them multiple times. The causes are often from slamming the door too hard or driving habits. Forcefully closing the door can loosen screws or clips, causing a clunking sound; at high speeds during turns, wind pressure can cause whistling noises from door gaps. Just adjust by closing the door gently. Also, check if the door glass is loose and ensure the window regulator screws are tight. I've tried removing the interior trim and tightening the clips, which eliminated the noise—a simple DIY fix. Additionally, regularly lubricate the hinges to prevent rust and friction, and avoid letting water accumulate to corrode metal parts. These small maintenance tasks can be done routinely to keep doors smooth and noise-free.
