2013 RAV4, 49k Miles. Six months ago, Toyota service rep recommended Driveline service. Today while performing (free) state inspection at same dealership, the Driveline service issue came up again. Is it really necessary? Seems each time they don't make much $$$ on a scheduled service, the Service reps start recommending 3-$-digit issues. I don't mind if I really need it, just don't want to get duped.
