Just purchased a 2019 LX. First car with CVT transmission.I noticed yesterday at highway speed of about 65 mph the rpms were fluctuating about 3 hundred I could see it on the RPM gauge and feel it. I put it in cruise control and it did the same thing. Is this normal for a CVT transmission? It's very annoying. I'm going to call the Dealership Monday but was looking for opinions on this here on the forum.
