“Three times now, our new 2019 Honda clarity has put me and my family in danger. Twice in november 2019, once in january 2020, the car suddenly lost power in the midst of driving up hills, once at highway speed. Each time the car has produced a terrible burning smell and sounds of high revving of the engine. In all of these instances, the battery was low, but the gas level and reported range of the car was high. Once the car was in eco mode, twice it was in other modes. …”

“Car engine makes loud banging noise when it is running on gas instead of electrical battery. I had asked Honda dealer to review but they say they can not do anything about it. It is feels as if car making so much banging noise from engine has inherent issue and will eventually catch fire.”

“The contact owns a 2019 Honda Clarity Plug-in Hybrid. The contact stated that after refueling and recharging the vehicle, the mile range indicator would display inaccurate mileage range information. The contact indicated that the mile range display would sometimes be far above the range capability of the vehicle and in some cases well below the range that should be achievable with a full battery charge and full tank of fuel.
