Rebuilt starter 1998 Maxima

My trusted mechanic installed a rebuilt starter with a 3 year warranty two weeks ago. The starter seems to be faulty since after getting the car back, the starter “chatters” like it is going to turn over, but doesn’t always engage. You know, the noise when you first turn the key before the engine actually engages. I took it back and he swears the car is doing nothing wrong. I have a 1994 Honda Accord that immediately cranks and the Maxima isn’t cranking that first with a newer starter. What should I do?
