3rd Generation Mercedes-Benz M Class Noisy Windows

The Mercedes-Benz M Class Third Generation (W166) was produced from 2011-present. The M Class, a midsize SUV, has gained popularity since its initial release. Stylistically, this make and model is somewhat similar to the E Class. Like any new automobile, however, this German import is prone to some common problems, and drivers have complained of noisy windows.

Some owners have reported popping or cracking sounds from one or more of their front or rear windows, while opening and closing them. The noises are often intermittent, and sometimes the sounds worsen in rainy weather. Other drivers have stated that the popping and cracking stops only once the seals are replaced. It is also possible, however, that the cause of such issues is a malfunctioning window regulator.

While some drivers choose to ignore the issue, this is no way to enjoy your luxury crossover SUV. Moreover, if the problem is mechanical, the window could completely stop working, allowing rain or snow into your German import. Troubleshooting and repairing malfunctioning windows are not typically do-it-yourself projects. In order to access the window regulator and other related parts and systems, the door might require extensive disassembly, and there are associated dangers, including a shattered windowpane.
