1NZ-FXE
"Toyota's first mass-market hybrid petrol engine (Prius NHW11/NHW20, Yaris Hybrid 2012-2020). An Atkinson-cycle 1.5 with a timing chain and an easy life thanks to the electric motor. Wear arrives late: oil burning past about 200,000 km and chain wear; on the 2004-2009 Prius the electric water pump was recalled. Check the recall and the oil level."
2GR-FE/FSE/FKS/FXE/FXS
"Toyota and Lexus 3.5 V6 (RX 350/450h, IS 350, RC 350, Camry, Highlander, RAV4 V6). Long-lived and smooth, with known but manageable leaks: early engines (to 2010) need the all-metal VVT-i oil line that replaced a rubber hose under a Toyota campaign, the front timing cover can seep (engine-out on the RX), water pumps wear, and 2016-2018 FKS engines had a cam-housing leak bulletin."
