Problem overview

Some Mercedes-Benz CLS550 owners report experiencing serious safety concerns related to their front windshields, including issues with the windshield being unglued, leaking water, and the risk of popping out at high speeds. Specifically, owners of the 2011, 2012, and 2014 models have noted visibility problems and wiper alignment issues. Additionally, water leakage along the top of the windshield during heavy rain or car washes has been frequently reported in owner forums.
