I need to take my Camry in for its first oil change. Is this covered under some type of plan since it's still new, or do I have to pay for the service?

Give your salesperson a call. Depending on the deal you got. Lots of COVERAGE options. MELODY TOYOTA IS ALWAYS HELPFUL! THEM THE ROBERTO MARTINEZ SENT YOU!!

I also have a new car from them. You should have that 2 year no cost thing ( can't remember what it's called ). So you should be okay not having to pay.

It could be covered, yes. You can schedule online here: https://www.melodytoyota.com/schedule-service-main.htm
