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.

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. We have been to the dealer 3 times, and they have been in touch with national Honda, who say that these symptoms are a 'normal characteristic' and that 'proper drive modes should be used, ' as if the problem was somehow my fault for not using the proper modes. I was sent a very short video explaining driving modes. If this car is designed so that sudden loss of power, burning smells and an inability to drive up a hill are a 'normal characteristic' then this car is a hazard. If the car is unable to go up a steep hill without a certain battery level, then the car should not be designed to deplete the battery below that level no matter what mode the driver has it in. If the Honda solution to the problem is for me to use modes to keep the battery over 60% charged at all times, (which is what they suggested the second time I went in) or to stay off of hills when the battery is low (as they suggested when I brought it in the 3rd time) then it is not the plug-in car with the driving range I thought I was buying. Here is detail on the last incident: I was on a highway on a big hill at full highway speed when suddenly the power gave out and the car started revving in an extreme way, and there was a terrible burning smell. Luckily, I was in the right lane and was able to pull off the highway quickly. My passenger and I were both shaken ' this car is a danger until this problem is fixed.
