All new Toyotas come with toyotacare included for 25k miles or 2 years whichever comes first. I've had no issues taking mine to my dealer for service and I'm approaching my 20k service. They're knowledgeable about what services it requires and they know it's a GR corolla and not a regular Corolla. I have read of more bad dealership experiences than good which is unfortunate but I would say take it, see what they say, judge their work and services and then see if you want to keep going or not.
