About the 2018 Lexus RX
The 2018 model year of the Lexus RX sits in the AL20 generation, a premium large suv that was Australia's #56-best-selling new vehicle in 2024. RX has been Lexus's SUV staple since 1998; the current 5th gen (2023+) added a turbo hybrid powertrain. Earlier 4th gen (2015-2022) is reliable but watch for V6 water-pump failures and verify hybrid battery health on RX450h.
