Just reach 150,000 miles on my prius 2017 three

As I understand it, the 'scheduled' maintenance repeats every 120,000 miles, so a 150,000 mile service is technically a 30,000 mile service. When my 2017 hit 150,000 miles, my service included oil change, coolant exchange and hybrid inverter coolant service. Total price around $400, but that was in March 2021 and I'm in a cheaper market, FL.

 

Toyota USA Warranty and Maintenance Booklet, the schedule only goes to 120K miles (or 12 years, whichever comes first). Being event-by-event format, it's humanly impossible to extrapolate without first translating to a table format schedule, with miles/months columns and service rows. See attached.

and probably an ATF change-out if that's never been done.
