Coolant flow-valve — now just outside free coveragemoderate
The coolant flow shut-off valve that trips 'Engine Maintenance Required' still appears occasionally on 2022 cars — but Toyota's Customer Support Program 24TE04 covered only 2018–2021, so 2022 owners are just outside it, and the complaint file includes drivers frustrated to learn their VIN isn't eligible. It's not common at this point, but if the message shows, budget a modest out-of-pocket valve repair rather than expecting a free fix.
