2018 Honda Clarity Electric Problems

I bought this car used with a governmental help from replace my ride program, since I bough the car form a dealer [XXX] ) within few days, I took it to the dealer twice for thermostat replacement and spark plugs. and recently, There was an extended warranty from Honda for the ac condenser as this car has a major problem with ac. I took it to the dealer Honda of Riverside, California and they told me, indeed your condenser needs replacement and the good news, In California, Honda has extended its warranty. Then, they said, but you need to replace your evaporator and I need to pay $2350.26 and they refused to replace the ac condenser under warranty without replacing the evaporator and paying that much of money. I called Honda for help (goodwill) and after about a month (without having my car and many emails and phone call and time and efforts) Honda final response was "sorry, you have high mileage" Case [XXX] I really need your help to protect me from them.

AC working intermittently since the day I bought. Honda replaced the condenser but now the evaporator is leak. This caused the defrost can not work properly. The leaking condenser and the evaporator are well known problems for Clarity owners. Honda should recall this.

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.

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.

The engine revs very high and the car dramatically slows down. This has happened three times (including today) in the two years I have owned the car. Once was extremely dangerous as it happened on an Interstate highway when traffic was at highway speeds. We were able to avoid getting in an accident though. Why is there no recall for this common problem with this car?

I received a notice in the mail last YEAR stating that there was a problem with fuel pump in Honda Clarity and there would be a recall. I cannot get my car serviced. Honda will not respond. A dealer said not safe to drive. And they said they have no idea if they will even have parts this YEAR. Help please.

Despite what your website says, there is a recall on this car - for the fuel pump. Honda has sent notice of the recall but they have NO parts and NO timeline for the repair. The dealer advised me not "to drive long distances" in the car - that is not an acceptable resolution. Also, I asked the dealer if they could narrow down part availability to "weeks, months or years" and they told me they could not.

THE CAR STOPPED AND TURNED INTENSELY. *TR

The steering makes a horrible clunking sound, and is impercice/sloppy. Dealership refused to acknowledge any issue. Increased effort required to stay within lane. Tie rods are not damaged or worn, issue appears to be with steering rack as far as I can tell.
