I’ve got a 2011 Lexus RX 450h here in Seattle, and let me tell ya, it’s been a mixed bag. The hybrid battery actin’ up is top on my list—had it replaced twice in three years. No issues with oil leaks, though. Keepin’ it clean’s key since those bi-xenons are picky with dirt! Love the ride but gotta stay on top of maintenance, especially brakes. Anyone else with these quirks or fixes?
So, down in Texas, my buddy’s 2011 Lexus RX 450h’s battery pack gave up on him, lotsa $$$ to fix. Heard other peeps moan 'bout hybrid system glitches too. Not much fun on the road when stuff breaks off. 
reliability 'n all that jazz.
