I do not know if this is normal or not, but I have a noticeable rough idle when first starting the car in the morning. I hate to say rough idle but it is undulating to make it noticeable. There is a vibration when first driving but after about 5 miles on the highway it becomes smooth and vibrations go away. I have 3k miles on the 2017 Maxima.

I have noticed the gauge on the dash is at normal temp but on the sport mode temperature gauge it is still cold. When the car smooths out the sports mode temperature gauge becomes normal temperature in the middle. I don't know if there is a correlation or not. I usually remote start the car for about 4-5 minutes before I hop in and drive off.

Anyone else experience this?
