On non-hybrid trims, the 2.5L A25A-FKS I4 and 3.5L 2GR-FKS V6 are both mature Toyota engines with no chronic failure modes; the A25A has scattered oil-consumption reports worth a quick check at high mileage.
Cold-start, check oil level and condition, listen for a smooth idle. Confirm no check-engine light.
