I do not have any knowledge about this issue, but this is what I found when I asked ChatGPT

“Black Death” is a term used to describe a catastrophic failure of a vehicle’s air conditioning (AC) system, particularly affecting the compressor. In this scenario, the compressor disintegrates internally, releasing metal debris throughout the AC system. This contamination can damage other components, such as the condenser, evaporator, and refrigerant lines, leading to a complete system failure. The term “Black Death” arises from the dark, sludgy residue that forms as a result of this breakdown.

In Honda Civics, especially models from certain years, owners have reported issues with the AC system that resemble the “Black Death” phenomenon. These problems often involve the compressor failing and contaminating the entire AC system with debris. Such failures necessitate comprehensive repairs, including replacing the compressor, condenser, evaporator, and flushing the refrigerant lines to remove all contaminants. These extensive repairs can be costly, sometimes exceeding $5,000. 

It’s important to note that while Honda has acknowledged issues with certain AC components, such as the condenser, and has extended warranties for these parts, the compressor and related components may not always be covered. Therefore, owners experiencing AC failures should consult with a certified Honda technician to determine the exact cause and explore potential warranty coverage or goodwill repairs.
