2020 Honda Insight Problems

I was driving to Pilates class and everything was normal but as I reached a railroad crossing the car suddenly and for no reason stopped dead on the tracks. Luckily for me there were no vehicles in front or behind me and there were no trains coming. I was terrified and wasn’t sure what to do but I pushed the Drive button and the vehicle went ahead as if nothing happened.

The vehicle unintentionally accelerated while pulling into a parking space. I was depressing the brake to slow down while making the right turn into the space. The engine suddenly revved up (as though you were depressing the gas and brake at the same time) and it accelerated forward (a though you suddenly released the brake while depressing the gas pedal) and the car lept forward, jumping a 3 foot long curb, striking the vehicle parked in front of me. The tires kept spinning as though the gas pedal was being depressed, even though the vehicle could no longer make any forward progress since it had run into the front of the vehicle parked in front of me. We’re it not for the vehicle in front, I feel that the car would have continued accelerating forward and could have caused injury or death to customers in the shopping center and/or damage to other vehicles or structures. The vehicle was towed and is currently in the body shop for repairs, but I don’t think this addresses my concern for the sudden acceleration. I don’t want to drive it in case the problem reoccurs and could cause further damage. I’ve reached out to Honda to see if I can tow the vehicle to their service repair center to try to diagnose the problem by reading data from the car’s computer, but they have not responded. I checked the floor mats and they were flat and properly installed. If I had mistakenly depressed the gas pedal (not likely as I was already braking as I approached the parking space), I would have thought that the collision avoidance system would have braked the vehicle. Airbags also did not deploy in either vehicle.

Battery keeps draining. On my 3rd battery and believe there’s a defect in the DC/DC converter (earlier recall - K9E). This has caused issues being stranded in the cold.

The contact owns a 2020 Honda Insight. The contact stated that after starting the vehicle, several unknown warning lights illuminated. During the failure, the brakes failed to function as intended, and the Lane Departure, Cruise Control, and Forward Collision Avoidance features failed to function as intended. The failure was intermittent. During the first failure, the vehicle was turned off and restarted after several minutes and the vehicle operated as intended. The vehicle was taken to the dealer and diagnosed with battery failure. The dealer also determined that the brake pedal simulator had failed. The vehicle was not repaired. The manufacturer was not notified of the failure. The vehicle remained with the dealer unrepaired. The failure mileage was approximately 18,000.

I believe the tire, wheel or suspension system failed while driving on the highway, causing me to hit my head on the driver's window and lose cosciousness. I skidded into a concrete barrier on the right side of the highway and was found unconscious at the scene. The damage to the passenger side body of the vehicle is minor and does not match the catastrophic failure of the wheel, leading me to believe the wheel failed and caused the crash, not that the crash resulted in the damage to the wheel. The vehicle is currently at a tow lot and available for inspection. Luckily, no other vehicles were involved, but I was injured and could have easily been killed, or injured and killed others as it is a busy highway, especially during rush hour when this occurred. Inspection by the insurance company is pending. The police did not investigate as a safety incident because they immediately said on site that almost all single vehicle accidents are drug/alcohol related and treated it like a DUI stop. I passed field sobriety tests and a breathalyzer on scene and blood work at the hospital showed no drugs or alcohol in my system. I am missing time and memories starting about 5 minutes before the crash and for about 30 minutes after as a result of my concussion, I do not remember much besides a feeling that my car was falling, then I remember being woken up by the cop asking if I was under the influence.

This 2020 Honda Insight performed “phantom braking” of the automated braking system when I was about to enter a clear intersection with no vehicles or obstacles in front of me. It activated the automated braking system and endangered my life and the lives of others over no real threat. This occurred 08/23/2025. The car is well maintained and does not have any service issues. This was completely random.

I WAS DRIVING AT 65-70 MPH ON A FREEWAY, AND ALL OF A SUDDEN THE CAR SPEED DROPPED EVEN MY FOOT IS ON THE GAS PEDAL, THE CAR SLOW DOWN TO 40MPH WHEN DECIDED TO PULL OVER TO THE SHOULDER, BARELY ENOUGH TIME TO GET OUT OF DANGER. THE CAR ENGINE SHOT DOWN BY ITS SELF, I COULD NOT MOVE THE VEHICLE TO THE FAR RIGHT ASS I WANTED TOO. THE WARNING LIGHT ON DASH BOARD INDICATED IN RED " POWER SYSTEM " BOTTOM OF IT IN WHITE LIGHT " POWER SYSTEM PROBLEM DO NOT DRIVE" THEN A MINUTE LATER, THE WARNING LIGHT CHANGED TO A RED LOGO OF A BATTERY 12 VOLT BATTERY CHARGING SYSTEM PROBLEM DO NOT DRIVE.

I was driving home from vacation when my engine splash plate came loose from my car on the interstate. The splash plate fell down and dragged on highway creating friction under my car. The metal had fallen down and was chipping away creating dangerous debris to my car and other cars on the highway. Roadside service was no help, per usual. I was traveling alone. The splash plate had to be removed entirely to prevent a fire and more damage to my car. I couldn’t remove the splash plate on the side of the interstate. I drove 30-40 mph to get help to prevent further damage or loss of property and my life.

The whole hood vibrates while driving or when is windy, very noticeable at times. It was replaced once, almost a year ago but now it needs to be replaced again. same problem eventually the latches will be damaged creating a very hazardous situation. This vehicle has not been on an accident

At approximately 148,000 miles the steering would have an intermittent notchy, or sticky, feeling while driving straight. While driving straight at cruising speed, I noticed that the resistance on the left side of the steering wheel was greater than the right side, then the resistance would decrease suddenly (release), and the steering wheel would rotate slightly to the right, but less than 1 degree, so it would be hardly noticeable on video. The issue seems to only present itself after the vehicle is driven 20-40 minutes and when the temperature is 47 degrees or higher. I have noticed it at low speed (15-20mph) and at highway speeds. If I recall correctly, the issue first presented itself when we had our first 60 degree day and I was driving on the highway with the wheel straight. Then as I accumulated miles throughout the weeks, I would notice that it didn't happen on colder days but then happened more often on warmer days. Now that the vehicle has ~148,800 miles on it, and the air temperature is 67 degrees, the issue presented itself this morning (4/1/2026) after 3 minutes of driving and during the first sweeping left turn on my commute and at approximately 40 mph. Then the issue continued to happen throughout the drive, eventually becoming nearly constant by the end of the 45-minute commute. I do have an appointment with the Honda dealer for diagnosis, but the service advisor and I suspect that the steering rack is failing.

DAMAGE TO THE POWER STEERING LINKAGE CABLE AND OXYGEN SENSOR CAUSED ALL ADAS SYSTEMS TO BE OFFLINE INCLUDING POWER STEERING. IF THIS UNIT WERE TO BE DAMAGED JUST ENOUGH AND FAIL WHILE DRIVING THIS WILL LIKELY RESULT IN A CRASH/COLLISION AS THE CAR BECOMES COMPLETELY UNDRIVABLE. LUCKILY SO FAR, THIS HAS HAPPENED WHEN THE VEHICLE WAS PARKED AND DID NOT CAUSE ANY INJURY. I FEEL THE VEHICLE IS UNSAFE UNTIL THEY FIX THIS ISSUE. IT HAS HAPPENED 3 TIMES NOW AND NOTHING SEEMS TO BE BEING DONE ABOUT THIS ISSUE AS OF YET FROM HONDA. THIS WAS BROUGHT FORWARD TO HONDA'S ATTENTION WITH NO AFFIRMATION THAT THIS IS A PROBLEM. IT FIRST HAPPENED IN SEPTEMBER LAST YEAR AND HAS HAPPENED TWO ADDITIONAL TIMES SINCE.

The contact owns a 2020 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 contact stated the vehicle had stalled on several occasions. Additionally, the vehicle occasionally failed to start-up. The local dealer was contacted, but the vehicle was not diagnosed or repaired due to the cost. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the failure. The failure mileage was approximately 49,000. Parts distribution disconnect.

On July 22, 2022 I was driving my Honda Insight 2020. I was on the highway, current mileage on vehicle 50,796 miles, my speed was normal at 65 MPH when the car lost the ability to accelerate and it stalled. I was forced to make an emergency stop on the side of the interstate. Vehicle displayed on the dashboard "Critical Failure Detected. Stop Driving When Safe" The acceleration on the car kept decreasing and when stop it displayed "Power System Problem. Do Not Drive." Pulling to the side of the interstate was very scary because trucks were flying at about 80mph. I requested for tow company to pick me up but after hour wait, I gave up waiting on the tow truck. I restarted the vehicle and I was able to take off again. The fuel gas showed half of tank so I continue to drive. Forty miles later down the road, the same issue occurred again. I waited 30 minutes and since I was near a gas station I filled up the gas tank to full capacity. I drove another 100 miles (very skeptical) until I reached my final destination. During my drive I felt like the car had difficulties going into gear above 65MPH. The following day I took the vehicle to the Honda dealer, they said they couldn't pin point exactly what it is. Test show no issues on their diagnostic computer. However, the computer show a record of time and issue happening. They believe it is a fuel pump sensor relay. The vehicle senses I am out of fuel, which is not the case. Honda dealer will replace the sensor/relay and I will pay for it. The dealer states this vehicle is not part of a fuel pump recall. This issue needs to be addressed before it creates a scenario with fatalities, which can easily occur.

On September 16, 2022, I was in an accident where a driver hit me on the rear passenger side. I went a through a green light of an intersection on the Mopac N feeder Road and Duvall. Either both our lights were green or the other driver was dishonest and his was red. Every airbag deployed. Based on the impact, it would be highly unlikely to sustain a cracked sternum. The impact was to the right and slightly behind me. I have requested information from Honda America on the airbags and they refuse. They further insulted me by telling to go to a dealership. After this, Honda is the last car I would purchase or lease. Having worked at dealerships for many years, I am certain Honda knows, as well as I do, that the dealer cannot or will not give me compete information on the airbags. My car was maintained and in amazing condition. The last time I was at First Texas Honda for service, the advisor brought it around because they were very busy. He said he was stunned it had 125,000 miles on it. It drove like it was brand new. Please see photos and reports. If you need any further information, please let me know.
