2018 Nissan Rogue - Noisy seat

Power seat - Whenever vehicle is started or shut off and the seat slides forward of back, the power seat makes an annoying, obnoxious noise… I thought something was stuck in the track but now I think it’s the motor going out. Guy at the local dealership said it just needed grease. He appears to be incorrect. Any thoughts? Thoughts?

I too think that suggestion is without merit.
Instead of that “guy”, have either an independent mechanic or the dealership diagnose the actual problem. Yes, there will be a diagnosis fee, either might waive the fee if they perform the repair.

Still under warranty? Let them try it, if they find it was not the problem they will go to the next fix,
