Power Seat works, but very loud noise

SDL

:
2016 Mazda CX-9 GT
Drivers seat bottom back/forth power adjustment works, but it makes a very loud noise. I checked and there isn't anything stock on the rails. Sounds like the motor is under heavy load with or without anyone on the seat. I just had my oil change and won't be back at the dealership for another 5 months or so - Has anyone else had this problem before?
