Hello! We just bought a 2015 FFH with 30k. After about six weeks, the engine begin to rev like the transmission was trying to shift but could not. When you accelerate the car it does gain speed(sometimes slowly, sometimes the electric seems to kick in and it goes faster) but the revving sound(like you have it in neutral) gets worse.
We took it into our dealership but they wanted us to leave it for two days just to diagnose it. Any ideas what the problem could be? My first instinct, of course,is that it is a bad transmission. But I thought perhaps the EV might have something to do with it(if the charge gets too low?)
Thanks and yes, I am a noob. My first post.
PS I have sent a couple of Health reports and there have no been no problems flagged.
