NHTSA Complaint #11663813 — 2020 HONDA CIVIC

The evaporator in my 2020 Honda Civic failed without warning, causing the air conditioning system to stop blowing cold air. This posed a safety risk, especially in hot weather, as it affected driver comfort and increased the chance of fatigue or distraction. The issue was diagnosed and confirmed by a certified Honda dealership, whose staff acknowledged that evaporator failure is a common problem in 10th generation Civics and that Honda corporate is aware of multiple similar cases. While Honda has extended warranty coverage for other A/C components, the evaporator—despite its high failure rate—remains excluded. The repair is extremely labor-intensive and costly, often exceeding what many owners can reasonably afford, which discourages timely repairs. In many cases, the failure is due to leaking refrigerant, which not only compromises system performance but also poses an environmental hazard. There were no warning lights or messages before the failure, and the component is available for inspection upon request. I am requesting that Honda extend warranty coverage to include the evaporator and provide reimbursement for repairs due to the widespread nature, safety concerns, and environmental impact of this issue.
