My "SERVICE REQUIRED" dashboard message came on at 6500 miles and only ten months from the date of purchase. My dealership covered the maintenance nonetheless.
I was told by technician that service is based not only on mileage, but also number of vehicle starts. So if you drive lots of short trips, the service interval will be shorter than the 15k miles used as a default.
Shop manager told me this when I asked if I had to remember servicing or if the vehicle would prompt me at required intervals.
I can only trust him but have no idea if this is true or not. Out of curiousity, do you drive a lot of short trips?
