NHTSA Complaint #11694663 — 2018 HONDA CIVIC

AC did not work at all when the outside temperature was hot. Service Bulletin 19-091 performed. AC blew cold after the repair. 1 year later AC did not work at all again. Dealership said the extended warranty will not cover it because it is an evaporator leak. This is a known issue and many have complained. If there is a leak in the evaporator then I would assume the refrigerant is leaking into the car and not outside the car. Risks of R1234yf Refrigerant: Flammability: R1234yf is classified as mildly flammable (A2L), meaning it requires a significant heat source to ignite but can burn. Toxic combustion products: When burned, R1234yf produces highly toxic and corrosive substances, such as hydrogen fluoride. Asphyxiation risk: A leak can displace oxygen, leading to a risk of asphyxiation in poorly ventilated areas.
