2019 Honda Insight other reported problems

UNKNOWN OR OTHER

The A/C evaporator failed due to a refrigerant leak caused by corrosion. The component is available for inspection upon request at the dealership where it was diagnosed. The failure resulted in complete loss of air conditioning. In hot weather conditions, particularly during highway driving and stop-and-go traffic, loss of A/C poses a risk of heat-related illness to the driver, especially in high-temperature climates. The defect was confirmed by a Honda dealership technician during an inspection in May 2026. The service advisor explicitly stated that the evaporator is manufactured from the same defective material as the A/C condenser, which Honda already acknowledged as a manufacturing defect under Service Bulletin 21-016. A Honda corporate customer relations representative independently confirmed the same information — that the evaporator shares the same material and is subject to the same corrosion issue. No warning lamps or messages appeared prior to failure. The first symptom was warm air blowing from vents, which progressively worsened until A/C stopped functioning entirely. Honda repaired the condenser under Service Bulletin 21-016 at no charge but refused to cover the evaporator repair, quoting approximately $2,600 out of pocket despite acknowledging the same root cause. I am requesting NHTSA investigate whether a recall or additional service bulletin covering the A/C evaporator on 2019-2021 Honda Insight vehicles is warranted, as other owners are likely experiencing the same defect.

Back up camera stopped working, no blown fuses and the system updates I can do on the car from the touch screen say everything is up to date. My car has no open/not repaired recall for this.

The air conditioning system in my 2019 Honda Insight Touring Edition has failed three times in the last 3 years. Why is this a safety issue? In Southern California summer temperatures reach into the 90s and driving without air conditioning is impossible for any distance. For example today it is 93 degrees Fahrenheit in Los Angeles. It's impossible to use my car without air conditioning. Additionally, the A/C failure causes water vapor to condense on the windshield glass making it difficult to see through it and is an additional safety issue. The AC failure in the Honda Insights is a known issue to Honda USA. They have extended warranties of the air conditioning units to 10 years. This acknwledgement proves that Honda know of the issue and don't want to resolve it for consumers.

I have a 2019 Honda Insight that has had two previous air conditioner failures that were covered under an extended warranty that Honda issued for the compressor and condenser based on known problems with the system. The air conditioner, as of 6/2025, has again failed for the third time. The local dealer Victory Honda of Morgan Hill diagnosed a leaking evaporator which Honda is refusing to cover as the car is out of factory warranty. Upon researching the matter online I learned it is a widespread issue and even resulted in an unsuccessful class action lawsuit. The air conditioner failures are a safety issue because the defroster does not function effectively without it. This can result in fogged windows causing impaired visibility while driving. I believe that the evaporator repair should be included in the 10 year air conditioner condenser and compressor warranty that Honda previously issued. The air conditioner is a closed system and whatever the root issues causing failures are, they don’t appear to be limited to just the two components covered under the extended warranty that Honda issued.

UNKNOWN OR OTHER

Consistent failure of A/C Evaporator and Condensor, which causes failure of entire A/C system and requires expensive replacement parts/repairs. Recall issued on Condensor but not on Evaporator, which makes no sense. Both are needed for A/C to run. The leaks from condensor and evaporator impact function of the engine by making it skip on acceleration. It also impacts the filter systems. Dangerous for health and safety.

Vehicle a/c system did not effectively cool cabin in warm weather on long drives. Last trip there were white particles coming from the vents. There is a known issue with the systems and Honda extended the warranty on a/c system due to problem condensors. Brought it to a dealer who found that the evaporator was leaking causing refrigerant to enter cabin area. Dealer quoted over $1500 to replace a part that was defective from the factory. Vehicle is out of bumper to bumper warranty and Honda has refused to cover the repairs.

A passenger became locked and trapped in the rear seat compartment after the driver and key fob walked away from the vehicle. The childproof lock setting in either the locked or in the unlocked position does not eliminate the trap. The problem is not addressed in the driver manual. It is highly likely that a passenger will eventually be killed as a result of this design in the event they are trapped in either hot or cold weather.

ACC, CMBS, RDM PROBLEM LIGJTS ARE ON. IT HAPPENS TWICE TIME WITHIN A YEAR OF OWNING THE CAR. I BROUGHT IT TO THE DEALER AFTER 3 DAYS OF PURCHASED THE NEW CAR (1ST TIME) AND WAS TOLD THAT THEY DIDN'T KNOW WHAT'S EXACTLY PROBLEM. THEY TRIED TO RESET THE SYSTEM AND IT WORKED. THEN IT HAPPENS AGAIN, SAME ISSUE, I BROUGHT IT BACK TO THE DEALER AND THIS TIME THEY WANTED ME TO REPLACE/REAIM THE SENSOR THAT ON THE FRONT BUMPER. THIS TIME THEY BLAMED IT ON THE MISSING COVER. I DID SOME RESEARCH ONLINE, IT'S A VERY COMMON ISSUE AND IT SHOULD BE THE MANUFACTURE PROBLEM. THEY NEED TO DO SOMETHING ABOUT IT BECAUSE IT COULD LEAD TO SOME SERIOUS ISSUE.

APPLE CARPLAY WILL OCCASIONALLY CRASH DURING VEHICLE USE, CAUSING THE CENTER INFOTAINMENT CONSOLE TO COMPLETELY RESET. IN THIS PERIOD, BACKUP CAMERA AND SIDE VIEW CAMERA ARE INACCESSIBLE FOR 30-60 SECONDS. THIS OFTEN HAPPENS MID OPERATION OF VEHICLE. FAULT NOT OF APPLE, BUT OF HONDA'S POOR IMPLEMENTATION OF CARPLAY.

TPMS (TIRE PRESSURE MONITORING SYSTEM) CONTINUES TO REPORT A PROBLEM WHEN THERE IS NONE. WE REPLACED A TIRE DUE TO SIDEWALL PUNCTURE A COUPLE OF MONTHS AFTER PURCHASE OF CAR. REPLACEMENT WAS SAME BRAND, SIZE, ETC EXCEPT IT WAS NOT THE TYPE OF LOW MILEAGE TREAD THAT MANUFACTURERS PUT ON NEW CARS IN OTHER WORDS IT WAS A TYPICAL AFTER MARKET CONSUMER TIRE. HONDA DEALER SAYS TO THEIR KNOWLEDGE ONLY FIX IS TO BUY NEW TIRES 2 AT A TIME OR EVEN 4 AT A TIME TO AVOID TPMS WARNING. THIS IS NOT A NEW PROBLEM WITH THIS TYPE OF TPMS SYSTEM. IN A FORM EMAIL HONDA OFFERED NO SOLUTION TO THIS PROBLEM WHEN WE FILED COMPLAINT ON THEIR WEBSITE. WE KNEW NOTHING ABOUT THIS PROBLEM WHEN PURCHASING THIS NEW VEHICLE. WE ARE OTHERWISE VERY SATISFIED WITH THE CAR. VERY FRUSTRATING.

THE DIGITAL MILES-PER-HOUR SPEEDOMETER WILL NOT APPEAR ON THE INSTRUMENT PANEL IN ANY 2019 HONDA INSIGHTS. IT WILL ONLY APPEAR AS KILOMETERS-PER-HOUR. A REPRESENTATIVE FOR HONDA USA SAYS THIS IS THEIR DESIGN, YET THEIR MANUAL CLEARLY STATES IT SHOULD APPEAR IN MILES-PER-HOUR. THERE IS A NEEDLE SPEEDOMETER THAT SHOWS MILES-PER-HOUR, BUT THIS IS OFTEN HIDDEN FROM SIGHT BY THE STEERING WHEEL. I THINK THIS IS A SAFETY HAZARD AS IS IS DIFFICULT TO KNOW THE ACTUAL SPEED OF THE VEHICLE.
