Coming Soon
Lexus RX AL20 (4th Generation)
2016–2022 · AL20 · suv
Fourth-gen RX moved to TNGA-K, kept the 3.5L 2GR-FKS V6 (RX 350) and 2GR-FXE hybrid (RX 450h), and added three-row L variants for 2018 (RX 350L, RX 450hL). F-Sport trim continued. Polarizing floating-roof styling. Top-of-mind for luxury-crossover shoppers throughout its run.
Watch out: Owner reports of remote-touch trackpad ergonomics (Lexus's most-complained-about UI of the era) and oil-cooler / pan-gasket weeping on 2GR-FKS past 100k mi. Three-row L variants have very tight third-row legroom — verify in person.
