“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. …”

It was determined that the condensation of the air conditioning was unable to drain due to the drainage tubing being clogged with insects, causing water to back up and short circuited the electrical system.”
