There are 6 owner-reported driver assist & adas complaints for the 2020 Honda Insightin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
I was driving on a two lane road driving over a small paved bridge going about 40mph with a car next to me and a car behind me nothing in front of me when my car did a hard phantom brake. No pre warning, the display did show BRAKE and it did beep. But everything was sudden. Luckily the car behind was able to slam on brakes. The car behind me continued to follow but was at least 4 car lengths away. I assume bc they didn't know why I braked.
I have had 2 occasions when I experienced inadvertent spontaneous braking. Both times there was no vehicle in front of me. Both times the car stopped completely while driving in the city between 25 to 35mph. Fortunately there was no vehicle behind me either time and I did not sustain any injuries.
In 3 instances the emergency braking system has activated when the car was being driven on the freeway and the lane was curving with no obstacles in front of the car in the lane but a semi truck in the next lane over in one instance and cars in the next lane over in the other instances.
Two instances of braking system activating at highway speeds. In one instance, it was broad daylight, there was some traffic but nothing in my lane for a good distance, highway speed (approximately 65 mph) short sharp braking maneuver that dropped the speed approximately 10mph. I assumed there was some reflected light off of a sign that messed with the sensors, but the second instance was at midnight, same highway, same speed, no one else on the road. In these instances, with light traffic, there was no danger to my safety but if this happens again under heavier traffic, it could conceivably cause someone to rear end the vehicle. I have not been able to reproduce the problem. There might’ve been a flash on the dashboard warning the system was activated, but I couldn’t say for sure. Vehicle is available for inspection.
VERY OCCASIONALLY THE CAR COLLISION AVOIDANCE SYSTEMS KICKS IN ERRATICALLY. THE CAR BRAKES AUTOMATICALLY TO REDUCE SPEED SUBSTANTIALLY. THIS CAN BE VERY DANGEROUS BECAUSE SOMEONE MIGHT HIT FROM THE BACK. THIS HAS HAPPENED TO ME ON CITY STREETS AS WELL AS THE HIGHWAY. I THINK IT MIGHT BE DUE TO THE COLLISON SENSOR MISSCLASSIFYING SIGNBOARDS OR OVERHEAD BRIDGES AS HUMANS OR CARS
DRIVING ALONE ON ROAD DOING 30 MPH THE CAR SLAMMED ON THE BRAKES AND SLOWED TO ABOUT 20 MPH WHILE FLASHING "BRAKE" IN INSTRUMENT CLUSTER. NO OTHER CARS ON THIS ROAD AT THE TIME. THERE WERE SHADOWS ACROSS THE ROAD FROM SUN AND TREES. SINCE I ALWAYS DRIVE THE SPEED LIMIT, IF THERE IS SOMEONE FOLLOWING ME, THEY ARE USUALLY RIGHT ON MY TAIL. I DON'T WANT TO BE SHOT FOR "BRAKE CHECKING" SOME REDNECK IN A PICKUP WHEN IT ISN'T EVEN ME DOING THE BRAKING. NHTSA ISN'T DOING IT'S JOB BY ALLOWING THIS ISSUE TO CONTINUE.
