What 24 owners told NHTSA about the 2018 Honda Clarity Electric

Since last Wed. (9/24/2025), the car started to show the warnings of "Adaptive Cruise Control Problem", "Brake Hold System Problem", "Brake System Problem", "Electric Parking Brake Problem", and "Road Departure Mitigation System Problem" from time to time. I bought this VHonda Clarity Plug-in Hybrid 2018 in June 2023 as the HoneTrue Certified. Then probably the same time, the car lose the EV mode by itself, and only drives in the gas mode. I found this issue and late manually changed it to EV mode. WHile then it again dropped the EV mode during the driving today (9/28/2025). When I tried to press the EV button, it shows "Drive Mode Change Unavailable"! After stopped at home, I re-started the car, I can change it to EV mode.

I was driving straight, no objects in my way, 100 yards behind the car in front of me, and the car automatically breaked with the brake sign flashing on the dash and dinging, bringing me to almost a full stop without my ability to control the car. I had been going ~50mph. It was jarring. I lurched forward, bags and anything on seats flew off. The car behind me almost hit me. There was no reason for the stop. The car has NEVER done this before. I drive 500 miles per week commuting.

VEHICLE'S SAFETY FEATURES (BRAKE ASSIST AND/OR COLLISION MITIGATION BRAKING SYSTEM) WILL ACTIVATE EITHER EXCESSIVELY OR OCCASIONALLY WHEN THERE IS NO OBSTRUCTION WHATSOEVER. THE FULL FORCE BRAKING IN TRAFFIC FOR NO APPARENT REASON COULD EASILY CAUSE ANOTHER VEHICLE TO CRASH INTO MINE.

NO SPARE TIRE PROVIDED. ROADSIDE ASSISTANCE PROMISED BY HONDA WAITING TIME HAPPENED MORE THAN 4 HOURS. THIS IS POTENTIALLY DANGER WHILE WAITING FOR ROADSIDE ASSISTANCE FROM HONDA AND IT DOESN'T HAVE SPARE TIRE. SINCE ITS NEW CAR PURCHASE, HONDA PROMISED THEY FREELY PROVIDE FIRST THREE YEARS ROADSIDE ASSISTANCE. MY RECENT TRAVEL GOT TIRE FLATTENED FRONT ONE PASSENGER SIDE. TOWING TO HONDA DEALER LATER FOUND TIRE WAS NOT REPAIRABLE ( MIEAGE AT THAT TIME 3000, 3 MONTHS OLD) . MY SUSPECT TIRE STRENGTH VS VEHICLE WEIGHT. 2) THE PEDALING SPACE FOR FOOT PLACEMENT WAS VERY NARROW WHILE PUTTING FOOT ON GAS /ACCELERATOR PEDAL AND INFACT UPPER PORTION OF FOOT IS TOUCHING /STRUCK WITH TOP OF COMPARTMENT CHANMBER IN THAT AREA. THIS IS SERIOUS ISSUE IF SHOE GETS STRUCK WHILE PEDALING. 3) WHILE SEAT HEIGHT ADJUSTED THE HEAD OF THE DRIVER AND ROOF ARE ALMOST TOUCHING. ITS VERY NARROW SPACE BETWEEN HEAD OF THE DRIVER AND ROOF. WHAT HAPPENS IF AN ACCIDENT , NOT SURE HOW SAFETY WITH THIS ISSUE?
