Cowl vent grille openings allowed normal environmental debris to accumulate, plug drainage and divert water onto electrical components and potentially result in a fire if not addressed. Some of the debris passes through into the hvac system and cannot be cleaned without dealer removal/repair of the hvac motor, which costs the customer more than $500 in repairs and disincentivizes mitigation. Furthermore, Mercedes is aware of the problem, has not issued a customer satisfaction recall, and instead, is charging customers more than $1,000 to install a plastic protective shield to prevent accumulation of debris, clogged water management, and risk of fire.
