Hello fellow Karma owners. I have a 2018 Karma Revero. Has anyone had issues with losing power while accelerating in Stealth mode? It has happened a few times where I am driving in Stealth mode on the highway and I don't take my foot off the pedal but the car drops in speed slowly and I step on the pedal over and over again to "give it gas" and it doesn't speed up. Then I'm just coasting and after a few seconds of this it works again and speeds up and then drops again. It's not every time or every day just every now and then. I'm concerned it will fail entirely at one point and I will be stranded. Thoughts? Thank you.
