This Problem Across All Years
The vehicle exhibits a dangerous electrical defect involving uncontrolled power-cycling. After shutting down the car, it automatically restarts itself in a continuous loop. During these episodes, the dashboard flickers, the drivetrain shudders, and the vehicle becomes unresponsive to manual 'Stop' button or brake inputs. Most critically, the car autostarts while parked in an enclosed garage. As a Plug-in Hybrid (PHEV), once the EV battery depletes, the internal combustion engine (ICE) engages automatically. This creates a life-threatening risk of Carbon Monoxide (CO) poisoning for residents in the connected home. A Honda dealership has professionally diagnosed the cause as a failure of the Body Control Module (BCM). This module failure also causes the anti-theft alarm to trigger uncontrollably and renders the keyless entry system inoperable. This defect turned the vehicle into a life-safety hazard in a residential setting.

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.

The infotainment display camera combination is the worst system in any vehicle I’ve seen that has these installed. If it is daylight the screen is nearly impossible to see anything plainly. Someone is going to back into other vehicles or people. This occurs every day the car is used and backed up while the sun is up.
