Mercedes-Benz CLS400 windshield reservoir leaking and rear tires wearing on inner side on Mercedes-Benz CLS400

Some Mercedes-Benz CLS400 owners report experiencing windshield reservoir leaks due to issues such as cracked reservoirs, broken pipes, or damaged seals and hoses. These leaks can be caused by aging, impact damage, or weather-related wear and tear. Repairing these leaks often involves accessing the reservoir pumps to replace grommets or fix cracks, with average repair costs around $348. Additionally, some owners notice rear tires wearing on the inner side, which may indicate alignment issues, suspension problems, or improper tire inflation. It is crucial for owners to have their alignment checked to ensure even tire wear and to prevent premature wear on the inner side. Regular tire rotations and maintaining proper tire inflation are recommended to extend tire life and prevent uneven wear patterns. Addressing these issues promptly is essential for maintaining the safety and performance of the Mercedes-Benz CLS400, and consulting a qualified mechanic is advisable if any leaks or unusual tire wear are observed.
