Have 2000 miles before service is due. On starting in indicator comes up indicating service is due. Is this an error or is something required. 2018 Sonata.

I'd say stop at the dealership and have them take a look. It might just be an error or the technicians forgot to reset the oil life.

I know my 2016 sonata you can set next service by either time or mileage on the instrument cluster. You should check the manufacturer recommended service or contact the dealer.

Being how it's a 2018 and probably still under factory warranty for sure stop into the closes dealership and they will be more than happy to check it out good luck.
