What owners wrote

“Air conditioner condenser needs replaced at 24,000 miles. Mechanic says he has worked on numerous exact models / similar year with same issue. Has there been a recall?”

“Service center states evaporator is leaking. The leaking ac components is a known issue to Honda who have issued a extended warranty for other AC component. R1234yf refrigerant is a flammable danger and leaking in the engine bay.”

“The problem is Compressor of the AC is faulty/damage. This is very common and i see a lot of people online having this problem. Its weird because they only warranty the condenser. Not Compressor which is also affected by bad manufacturing. Please help bring this to light and let it fully covered all AC parts. Thank you in advance”

Should you keep driving it?

This page can't tell you that. 0 of 100 reports involved a crash and 1 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
