“My AC has stopped working twice! First time was sept 2019. I was charged $300 for refrigerant. Second time was april 27, 2020. I was told it was the evaporator core. Honda corp told me it would take 3 months for the part to arrive in ca. I live in palm springs where weather can reach up to 118 degrees. This is very unacceptable. I went on the clarity forums and discovered that many many other owners are experiencing the same A/C issues.”

“On january 13, 2019 my wife and I were driving on a 1.5 hour trip on a 4-lane freeway. The outside temperature was 30 degrees. While driving at 70 MPH, suddenly the internal combustion engine revved up dramatically while simultaneously the car started slowing down uncontrollably. My wife, who was driving, would push the accelerator and the engine would rev up, but the car continued to slow down. It was as if the wheels had become disconnected from the power source. …”

“Since receiving the leased vehicle I've had it back to the dealer 3 or 4 times for checks on the transmission. The car sporadically disengages gears when applying acceleration, local and highway driving. I've registered the complaint with the service department from the beginning of the lease and was told each time that there was nothing wrong. They never took the transmission (or whatever runs it ) apart to really see what the problem might be. This is true because they could not check into anything like that in the time space of an oil change. …”

“I have driven the clarity for 4 months. This has happened three times in heavy traffic with Honda sensing turned off and no cruise control. If I am following the car ahead closely and the vehicle ahead slows down , but not enough for an accident, the clarity stops unnecessarily quickly, scaring me and putting me at risk of getting hit from behind. It's scary. I am very capable of stopping the car on my own and do not need the car overcompensating. If I turn all the safety features off, I do not understand why this is happening.”

“The clarity phev is incompatible with public charging stations (e.g. Chargepoint) that feature dual charging ports and an energy management controller (emc). The vehicle's onboard charger will shut off when it senses the charging station's emc is activated when both ports are engaged for simultaneous charging. Multiple failed attempts to restart charging will result in a total system failure warning from the instrument panel causing the vehicle to not start and drive. …”
