On a random basis our new clarity suddenly loses power and sounds like we have shifted into neutral even though we are just continuing in drive mode. this has happened several times a month since we bought the car in june 2019. we have had the car tested at the dealership where we bought the car and they could not replicate the problem. in august this year we were making a 2 hour drive and on a toll road with an incline in riverside, ca the revving sound was really loud and when i pushed the gas peddle, nothing happened. i pulled over to the side of the highway and turned off the car. i turned it back on and put the car in hybrid mode and out of electric and pulled back on the road. the exact same sound and lack of acceleration occurred. we called the dealership and they said to use aaa to be towed which we did. again, ocean honda could not find an issue on their computer diagnostic system or road testing for 2 days. we continue to have the issue a couple times a month in very different driving conditions, speeds, modes, etc. we contacted honda america and they had the car tested at our new location in rancho mirage at honda of the desert. again, testing showed nothing. honda america has offered no solution and we are now afraid to drive the honda clarity for anything other than local drives. i put date of worst incident in section where asked when problem occurred, but it is ongoing.
Tl* the contact owns a 2019 honda clarity plug-in hybrid. while driving 70 mph up a hill, the vehicle failed to accelerate and lost power. additionally, the miles per gallon for a fully charged battery was supposed to be 48 miles; however, the actual range was 38 miles. the vehicle was taken to norm reeves honda superstore west covina (located at 1840 e garvey ave s, west covina, ca 91791, (626) 251-2995) to be diagnosed. the mechanic test drove the vehicle, but was unable to duplicate the failure. the contact was also informed that the vehicle charged and operated as intended. the vehicle was not repaired. the manufacturer was notified. the approximate failure mileage was 2,200.
The car drives fine when there is sufficient battery. when battery level drops to low (2 bars) the car does not respond to accelerator. the engine becomes sluggish and revs up quite a bit. i have driven ~650 miles so far and this has happened 4 times already. luckily it happened only once in the highway where this would have been dangerous and life threatening.
