2016 Honda Civic

The A/C failed completely, blowing hot air (80+°F) in extreme Phoenix heat. The issue recurred identically after a dealer misdiagnosis and gas recharge last year. A formal inspection by Showcase Honda on May 28, 2026 (RO# 838832), confirmed a dual leak: the A/C Compressor Shaft Seal (under warranty extension) and the A/C Evaporator Core were leaking refrigerant simultaneously. Due to severe local heat waves, repairs were completed at the dealer on June 15, 2026. Invoices are available upon request. This defect severely risks vehicle safety. Driving in Arizona's 100+°F heat without A/C causes immediate heat exhaustion for passengers. Also, losing the defroster causes sudden windshield fogging during humidity shifts, creating a blind visibility hazard. No warning lamps preceded the failure. Crucially, the 10-year warranty extension is rapidly expiring for early 10th-gen Civic owners, leaving us unprotected. NHTSA must mandate Honda to extend the compressor/condenser warranty to a LIFETIME warranty. Furthermore, because the Evaporator Core inherently fails at the exact same time due to the same loop defect, Honda must expand coverage to include the Evaporator Core as a fully covered component. Partial coverage is a widespread safety hazard and a financial injustice for consumers.

What component or system failed: The entire Air Conditioning system, specifically the AC Compressor, Condenser, and Evaporator, failed catastrophically. The authorized Honda dealer diagnosed it as "Black Death," meaning the AC compressor internally shattered, sending metal shrapnel and contaminated oil throughout all AC lines and components. How was your safety put at risk: This failure is a SEVERE SAFETY HAZARD. Because the AC compressor is dead, the windshield defroster/defogger system no longer functions. During rain or changes in temperature/humidity, the inside of the windshield fogs up instantly and cannot be cleared. This causes a sudden and complete loss of driver visibility, creating a high risk of a fatal crash on the highway. Has the problem been reproduced or confirmed: Yes. The vehicle was inspected by an authorized Honda dealership. The technician confirmed the catastrophic failure ("Black Death") and stated the entire system needs to be replaced. Previous history & Manufacturer response: Honda has known defects with the 2016 Civic AC system (Warranty Extensions 19-091 & 23-039). The condenser was previously replaced under warranty in 2023. Now, the defective compressor shaft seal has led to the complete destruction of the system. Despite this being a known defect that causes secondary damage to the entire system, Honda Corporate has refused to cover the repair costs for the collateral damage (evaporator and lines). The parts are currently on the vehicle and available for inspection. Were there warning lamps: There were no warning lights on the dashboard prior to the failure. The only symptom was the AC suddenly blowing hot air and the immediate loss of the defogging capability.

My A/C system experienced a total failure at around 79,000 miles. I took the vehicle to a service center, and they confirmed the failure is the A/C Evaporator. This component is now broken and available for inspection upon request. This evaporator failure is an extremely common, widely reported issue across this generation of vehicles and is almost certainly due to a manufacturing defect. The failure creates two major safety risks: First, the loss of defrost capability causes the windshield to fog up immediately in rain or humidity, which completely blocks the driver's view. Second, the extreme interior heat caused by the lack of A/C creates severe driver fatigue and distraction, which impairs safe operation of the vehicle. This issue has been confirmed by the dealership, and there were no warning lights.

The evaporator core is leaking, which is causing reduced visibablility out of the windows due to condensation on the windows, mold-like smells from moisture from the interior cabin (it is available upon request). I took it into the dealer - they examined the issue (the shaft seal had just been replaced in April of this year) and let me know that this time the evaporator core was leaking. For context and why I bring it to the attention of the NHTSA is in early to mid-August of this year my AC not only took an extended time to get cool, it only got cooler, and not cold. Unfortunately, I am now well acclimated to the signs of a faltering air conditioning system after dealing with three like episodes on the same vehicle, occurring within 2 to 3 years of each other (the car isn’t even nine years old). In fact, this vehicle’s air conditioning has been in a rhythmic pattern of failing ever since I purchased the vehicle. Over 8 years there have only been a few summers which haven’t been negatively impacted by this inconvenience. Honda is aware of the issue, because they have offered "good-will" subsidies which sometimes cover partial replacements of these components. But, they have yet to take responsibility for anything outside of the condenser. Hence, the consumer is on the hook to pay for a vital piece of the car (not just the convenience) that removes moisture out of the car.

The day i bought this car the ac went out. I had to go back to dealer the next morning. I later on learned They just fiddled with it to make it work temporarily. By the next summer ac went out again, this time defrosters didn't work, heater didn't work, ac obviously didn't work. And ive Been dealing with it like this for over 2 years. Honda is not helping at all.

THE AC SYSTEM ON THESE MODELS HAVE A FACTORY DEFECT. I WAS DRIVING ON THE SURFACE STREETS THE WINDSHIELD BECAME FOGGY, I COULD NOT SEE TRAFFIC IN FRONT OF ME AND SUDDENLY STOPPED IN THE MIDDLE OF THE ROAD. I GOT OUT OF THE CAR AND CLEANED THE WINDSHIELD WITH THE PIECE OF TOWEL. BECAUSE THE CAR'S AC WAS NOT WORKING IT COULD NOT DEFOGG THE WINDSHIELD. I HAVE CONTACTED HONDA, BUT HONDA DOESN'T REPAIR IT. IT IS A SAFETY ISSUE.
