It is unknown what system failed. While coasting to slow for the stopped car in front of me, the car began aggressively accelerating without warning. Adaptive and standard cruise control were both off. Lane keep assist and road departure were also switched off. Due to the slick nature of the road, the acceleration left me traveling far too fast with little space to stop. After sliding to a stop, I was within a foot from the car in front of me. This failure very nearly caused an at-fault accident which there was nothing more I could do. Note that this happened roughly 40 mins into a drive, which was otherwise uneventful. No warning lights were present before, during, or after the issue. This car has been having phantom braking issues and power loss issues consistently since March and has spent significant time in Honda's hands for this issue. The vehicle has come to a near stop on the highway from the previous braking issues and has lost power, stranding me in traffic on a highway. It is suspected that the same system failure that caused those issues has come back up again. To date, thousands have been spent on repair "guesses" and tow bills with no end in sight to these safety issues. This vehicle has become a liability and, as a result, inspections are strongly encouraged. I have included photos of the floor mats as they were at the time, properly secured and not near either pedal.

An UNKNOWN SYSTEM or the FOB recently started causing the vehicle's trunk to unlock and/or windows to roll down. This presents SAFETY and THEFT issues since someone could enter the car or trunk without the owner/driver being aware of their presence. Also, the trunk popping open while driving is a distraction and blocks the view through the rear window. We traded a previous year's model of the same vehicle due to the same problem. The trunk light comes on if the trunk opens while the vehicle is in operation, but there is no way to know the trunk is open if the car is parked.

The ANC (active noise cancellation) software is not up to date. It's causing a loud, uncomfortable booming or humming noise from speakers while driving. 2018-2021 models are having the same issue. Many honda accord sport 1.5 or 2.0 owners I talk to are experiencing the same problem. And are being told by local Honda dealerships they don't see any issue.

Just before March 2, 2021 shortly after purchasing this new vehicle I discovered a safety hazard in which the passenger window will not roll down, I brought it to Hoehn Honda in Carlsbad on March 2 and they oiled the window to make it work. I had concerns that they did not replace the motor mechanisms and it would fail again which it has. Today May 17 2021 I was not feeling ill at work and went to sit in my car to roll down the windows to get a breeze and again the passenger front seat window is stuck. One or two times it seemed like it didn’t work but on the next try it did after the repair. now it’s frozen again. Having non-operational windows is a safety hazard and a passenger hazard, and a law enforcement hazard if pulled over and the window will not roll down. It is stuck in the up position. The dealership has no interest it’s a safety hazard and requires i drive it in and will not provide me a loaner car.

LAST YEAR A COUPLE OF WEEKS AFTER I PURCHASED MY CAR I CAME OUT THE STORE TO DISCOVER THE GAS TANK DOOR OPEN AND THE CAR WAS LOCKED. WHEN I CALLED THE DEALERSHIP ABOUT THE INCIDENT IT WAS BRUSHED OFF. THE SPEED LIMIT SIGN CAPTURE CAMERA SHOWED THAT THE SPEED LIMIT WAS 90 WHEN I WAS IN A 35 MILE ZONE, IT HAD CAPTURED THE LAST TWO NUMBERS A ROUTING SIGN INSTEAD OF THE SPEED LIMIT SIGN. I WOKE UP ONE MORNING TO FIND MY CAR WINDOWS DOWN, THE SUNROOF OPEN AND THE CAR WAS STILL LOCKED. THE KEYS WERE STORED IN A PLACE WHERE THEY WERE NOT TOUCHING ANYTHING, SO THERE WAS NO LOGICAL EXPLANATION FOR THE WINDOWS TO BE DOWN AND THE SUNROOF OPEN. THE CAR HAD NOT BEEN DRIVEN FOR A COUPLE OF DAYS PRIOR TO THIS INCIDENCE. I CALLED THE SHERIFF'S OFFICE. ON MARCH 18, 2021, I DISCOVERED THAT THE GAS TANK DOOR WAS NOT LOCKING AT ALL.

Jan 2021 Injury

THE FIRST WEEK I HAD THE CAR I PULLED INTO A PARKING SPACE AT A FAST FOOD RESTAURANT IN NASHUA, NH AND WENT TO GET OUT OF THE CAR. I PUSHED THE IGNITION BUTTON TO TURN THE ENGINE OFF BUT INADVERTENTLY FORGOT TO PUT THE CAR IN PARK. THE PARKING SPACE WAS ON A SLIGHT INCLINE WITH THE SLOPE GOING TOWARDS THE FRONT OF THE CAR. WHEN I ATTEMPTED TO STAND UP TO GET OUT OF THE CAR THE CAR CONTINUED TO ROLL, KNOCKING ME OVER, CATCHING/TWISTING MY RIGHT LEG IN AND UNDER THE DRIVER SEAT AND THE DOOR (FRACTURING IT IN TWO PLACES REQUIRING ME TO BE WHEELCHAIR BOUND AND NON-WEIGHT BEARING FOR 8 WEEKS). AS I PULLED MY RIGHT LEG OUT, I WAS ON THE GROUND AND THE DRIVER-SIDE REAR TIRE RAN OVER MY LEFT LEG. FORTUNATELY A CURB AT THE END OF THE PARKING SPACE STOPPED THE CAR FROM ROLLING, BUT ALLOWED IT TO ROLL FAR ENOUGH FOR MY LEFT LEG TO NOT BE TRAPPED UNDER THE TIRE. AFTER THE INCIDENT, I MUST HAVE BEEN IN SHOCK AS I GOT BACK IN THE CAR AND DROVE TO MY DAUGHTER'S HOUSE ABOUT 10 MINUTES AWAY. I HAVE DISCUSSED THIS WITH OTHER PEOPLE AND MANY OTHER CAR MANUFACTURERS HAVE A SAFETY MEASURE IN PLACE WHERE IF THE DRIVER SIDE DOOR IS OPENED WHILE THE CAR IS IN DRIVE IT WILL AUTOMATICALLY STOP SO IT WILL NOT RESULT IN THIS TYPE OF ACCIDENT. I BELIEVE THAT THE FAILURE TO HAVE A SAFETY MECHANISM IN PLACE (LIKE NOT DEPLOYING AIRBAGS IF NO WEIGHT IN THE SEAT, OR TURNING OFF THE LIGHTS AFTER A CERTAIN PERIOD OF TIME IF THEY ARE LEFT ON, ETC.) RESULTED IN THIS HAPPENING AND MY UNDERSTANDING FROM OTHER IS THIS COULD BE AS SIMPLE AS A SOFTWARE UPDATE. I BELIEVE HONDA SHOULD IMPLEMENT SIMILAR SAFETY MEASURES THAT OTHER CAR MANUFACTURERS HAVE IN PLACE TO PREVENT THIS FROM HAPPENING TO SOMEONE ELSE.

"TRAFFIC SIGN RECOGNITION SYSTEM" SEEMS TO RECOGNIZE HIGHWAY SHOULDER MILEAGE MARKERS AS A SPEED LIMIT BECAUSE THE SMALL SQUARE SIGNS HAVE BLACK LETTER ON WHITE BACKGROUND. [PENNSYLVANIA, UPPER MERION TOWNSHIP]. THE CAR'S OCR ALGORITHM PROCESSING IS FLAWED. SHOULD BE LOOKING FOR WORDS LIKE SPEED AND LIMIT IN ORDER TO REDUCE THE ERROR RATE. ALSO SHOULD TAKE INTO ACCOUNT THE CAR'S AVG SPEEDS FOR THE PAST 5 MINUTES TO FILTER OUT FALSE SIGN RECONITION. REPORTS SPEED LIMIT OF 65MPH IN 35MPH ZONE. ONCE REPORTED SPEED LIMIT 120MPH. THE HIGH ERROR RATE CAN LEAD TO DRIVER CONFUSION AND/OR MISINTERPRETATION OF CURRENT SPEED LIMIT. WHILE IT IS A NICE FEATURE, ITS ACCURACY NEEDS TO BE IMPROVED. FALSE READING HAS HAPPENED OVER SIX TIMES IN THE PAST FEW WEEKS.

I WAS STOPPED AT A STOP SIGN. WHEN I STARTED TO GO AGAIN MY CAR WOULD BARELY MOVE. ALL THE WARNING LIGHTS STARTED FLASHING WITH ONE SAYING TO TAKE THE CAR TO A DEALERSHIP IMMEDIATELY. I WAS NOT ABLE TO DRIVE THE CAR ABOVE 20 MILES PER HOUR. I PULLED OVER AND CALLED THE MY DEALERSHIP, THE CLOSEST ONE. MY CAR WAS TWO WEEKS OLD. THE SERVICE DEPARTMENT SAID THE COMPUTER STOPPED TALKING TO THE CAR. THEY WERE UNABLE TO FIND THE ROOT CAUSE, AFTER HAVING THE CAR FOR 17 DAYS. I FEEL UNSAFE IN THIS VEHICLE.
