2019 Honda Insight

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.

The daytime running lights started to fade it till there was nothing. I was told it would be over $2000 to fix

The contact owns a 2019 Honda Insight. The contact stated that while driving 75 MPH, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. In addition, several unknown warning lights were illuminated. The contact stated that the failure had occurred while driving on a busy highway. The vehicle was driven onto the off-ramp and turned off the vehicle. The vehicle was started; however, the failure reoccurred. The vehicle was taken to the dealer, where it was diagnosed with a corroded connector and broken pin at the leak detection pump in the rear of the vehicle. The contact was informed that the leak detection module and wiring harness needed to be replaced. The vehicle was not repaired. The contact stated that the failure was a known failure with the vehicle. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 81,000.

Car was put into reverse to perform a T turn to drive in the opposite direction on 1/14. The "D" button was depressed to place the car into Drive. The car quickly accelerated backwards and crashed into the mailbox. Service Advisor at the David McDavid Honda Dealership was contacted yesterday regarding the issue but no response has been received yet. It is unknown if the backup camera was visible since attempts were being made to try to stop the car. Not much time was allowed.

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 Honda Sensing suite's CMBS uses a combination of a front-facing camera and a radar sensor, it detected a sewerage as a hole and steel plates as a hole and made a sudden unsafe stop. Collision Mitigation Braking System (CMBS) experiencing a false positive. We were going to like 15-20 over the steel plate and it made an emergency unsafe stop. It keeps doing it over and over. At this point it’s becoming really unsafe so I wanted to report it. It stopped all of sudden and made my neck in pain as my wife’s back. No the problem has not been talked to the dealer or they never told me about this kinds of problems will happen. No any warning lamps.

While stopped at a train track, I used the Brake Hold feature and it was on when suddenly without touching peddles the car went forward and I hit the car in front of me

On [XXX] while driving my 2019 Honda Insight Touring at approximately 35 mph on [XXX] , the vehicle’s automatic emergency braking system suddenly activated without any obstacle present. The car braked very hard, creating a dangerous situation in traffic. This was not the first time it has happened. The same issue occurred on two separate occasions in 2022, also with no vehicles or obstacles nearby. Each time, the system engaged abruptly and without warning. I am concerned about the safety risk of the Collision Mitigation Braking System (CMBS) activating erroneously, as it could easily cause a rear-end collision.

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.

The lane departure warning system in my Insight has, for the six years I have owned it, regularly been confused by shadows on the road - flashing a departure warning and trying to adjust the steering while I am driving within my lane. I was prompted to write this today because the LDS went off four times during my 8-mile drive to work this morning. It's mostly been a distracting annoyance, but as far as I know the system can't be disabled - just turned off manually every time the car is started. In sum: the vast majority of the times the lane departure system has alerted, the vehicle has not in fact been departing from a lane, but the LDS appears to be responding to shadows on the road - particularly in the morning and afternoon when shadows are darkest, and specifically while crossing a cable-stayed bridge (the cables cast lines of shadows across the roadway). I will put a date in your form, but this has been going on since I bought the vehicle in 2019.

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.

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.

Driving normally about to enter a clear intersections when the brakes automatically fully engaged bringing the vehicle to a complete stop. There was nothing in front of me, and no cars about to cross in front of me. Lucky there was no accident and I was able to continue on. There have been no issues, inspections, or changes leading up to this incident.

The contact owns a 2019 Honda Insight. The contact stated that while her husband was driving the vehicle at an undisclosed speed, the automatic braking system failed to deactivate as intended. There was no warning light illuminated. The contact stated that an appointment was scheduled with the dealer to inspect the vehicle. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 90,000.

The car was serviced due to a recall about fuel pump defect and after the service, the car was halted in the middle of the trip. This incident is not acceptable and especially the recall service was supposed to fix that problem. The sudden stop of malfunctioning fuel pump could cause collision, injury and possible lives!

Was taken into the dealership on 1/27 for an oil change and a general check-up. This morning 1/29 before starting up the vehicle noticed that the windshield had cracked windshield that looked like it was due to a bubble being created between the panes of glass which caused it to crack and shatter. This is not only a safety concern but an issue as well. Thankfully I was not driving the vehicle at the time that this happened.

I experienced an inadvertent emergency braking action in my 2019 Insight while cruising at highway speed. I was in the right lane, which had just doubled in width due to an on-ramp joining the highway. This situation will sometimes confuse my car's Lane Keeping Assist System, causing a side-to-side shudder or swerve, but in this case the Automatic Emergency Braking activated, causing me to lose about 10-15 mph in speed. There were no other cars around, and I never lost control of the vehicle. Most of the time, an AEB activation like what I experienced is completely harmless. There are no other cars around, and the road surface is good enough to prevent a loss of control. If another car is close behind or the road surface is extremely poor (ice, substantial water, etc.), this experience could possibly result in a rear-end collision or a spin-out. Because my AEB incident was harmless, I never reported it to the police, insurance, dealership, or manufacturer. I'm unaware of any warning lamps, messages, or symptoms before or after that could be related to the incident. As you can see, my report is anecdotal and I didn't save any precise documentation (e.g. dashcam footage) from when the incident occurred. My main goals in reporting are to corroborate the potential issue in investigation EA25002 and add my car's VIN as another data point.

I was stopped at a stoplight and then the light turned green. I began to accelerate and immediately and simultaneously my car began flashing BRAKE, beeping, and slamming on the brakes. I came to a literal grinding halt. There was no car in front of me nor was one merging into my lane. It was completely unwarranted and quite honestly frightening. There was a car behind me but thankfully they did not hit me. The CMBS clearly malfunctioned. Because there was no collision I did not file a police report. This however did put me at a huge risk of getting rear ended. The car has not been inspected since as this is not an open recall. There were no warning signs (lamps, messages, etc) before this occured.

The contact owns a 2019 Honda Insight. The contact received notification of NHTSA Campaign Number: 23V858000 (Fuel System, Gasoline); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

When we took it in for the front seat, buckle recall, we informed the dealership there was an issue with the driver side rear seatbelt. At that time, we only had two kids. Now we have three children, and we are not able to buckle all our children in the backseat. Each time we take the car to the dealership for an oil change we tell him the same issue they state there is no recall and won’t look at it. . How can you help?
