2020 Honda Civic

I am writing to file a complaint regarding the air conditioning system failure in my 2020 Honda Civic Sport. The air conditioner in my vehicle began blowing hot air instead of cold air starting in January 2024. I took the vehicle to a mechanic for inspection, I was informed that the evaporator has failed and needs to be replaced. While researching this issue, I discovered that many other Honda Civic owners have reported similar air conditioning problems involving the evaporator and AC system. I also became aware of a 2021 letter involving American Honda Motor Co. and Honda dealership personnel regarding evaporator leaks in vehicles with VIN numbers beginning with 2HG or 19X. The letter stated that Honda was researching these vehicles in an effort to better understand the issue. Given the number of similar complaints and Honda’s apparent awareness and investigation into evaporator leaks, this appears to be a potentially widespread defect affecting these vehicles, even when properly maintained. The failure of the air conditioning system has caused significant inconvenience, medical issues and financial burden. I have severe Hyperthyroidism, and reside in CA. Due to extremely hot weather & no A/C, the heat affected my heart rate and health severely. My honda is utilized daily for employment & commitments. Without proper air conditioning in almost 3 years now, while driving my car, I was admitted into the hospital last summer 2026 for 5 days due to the extreme heat affecting my heart and almost causing me to go into a coma aka [thyroid storm]. I believe this issue should be investigated further, as it may indicate a defect in the vehicle’s air conditioning system. I respectfully request that the NHTSA review this matter and investigate whether the evaporator failure in the 2020 Honda Civic Sport is a recurring manufacturing defect that may warrant further action or assistance for affected vehicle owners. Thank you for your time and attention to this matter.

Purchased the vehicle on 3/5/2022 with less than 10k miles on it. Within the first 2 months of driving the vehicle, the infotainment screen would freeze while driving and reset. One of these occurrences happened while driving on the highway at which time when the screen froze, turned a different color, and all the lights on the dashboard turned on simultaneously resulting in me not having control of the vehicle mechanics. This lasted for a few seconds, however, driving at a speed of 65 mph without control of the vehicle mechanics was and is extremely dangerous which could have resulted in an accident causing damage, injury, and death. This occurrence happened a total of three times. After a few months owning the vehicle on the first attempt utilized the key fob to lower my windows which resulted in the battery draining and the vehicle inoprable. Since my vehicle is my kids and my only mode or transportation I had to go to the nearest open Autozone to purchase a new battery. Mind you this was on a Sunday night about 9:00 pm so I had to catch an Uber to the nearest open store about 25 miles away. Once I returned home I replaced the battery and the car started at which time I called it a night. The next morning when leaving home for work and taking kids to school the Infotainment Screen was frozen with a black Honda logo as well as a manlfunction with the reverse and side camera. I have taken my vehicle to the local Honda dealer twice on a Saturday since this is the only available free time I have, however, on both occasions both Service Associates conveyed they had not heard of this malfunction previously and that the vehicle would need a diagnostic test I could not afford. The incident occurred on 5/24/23.
