Hello, have a 2023 pathfinder with about 10k miles on it. I’ve noticed that intermittently there is a rough idle. Is this something to be concerned about this early in the car’s life?

The fuel pump was replaced under warranty at 5k miles.

Also noticed that the car sometimes will rev the engine slightly when putting the car in park. The RPMs with the car in drive and the foot on brake will be close to 1200; however, putting the car in park will rev the engine to closer to 2k for a minute or two before it slows back down and stabilizes.

Something to be concerned about or no big deal?
