What's the temperature outside? The CVT will in many instances run "rough" when the temperature dips below 40 degrees. But will start to perform normally when the CVT reaches its normal operating temperature.
When I had a '13 2.5 CVT as a loaner, I noticed that the engine appeared to labor a bit and seemed rough within the first 30 minutes of driving it --- then eventually self-resolved. However, the 2.5 CVT will always seem loud due to the nature of the CVT being mated to the 2.5 engine. I was very surprised as to how unrefined the 2.5 CVT performed in comparison to how the 3.5 CVT performs.
