Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2025 RX500h.
The 2025 Lexus RX500h routes power through an Automatic (S6) transmission and carries EPA fuel-economy estimates of 27/28/27 mpg. In reliability tracking, this model year has generated just one owner complaint, filed under Visibility, alongside two recalls. For researchers, that minimal volume of reported problems indicates a currently quiet reliability profile, offering a small but concrete dataset dominated by those two recall actions rather than widespread owner-reported defects.
