TrueDelta Reviews the Reliability And Durability of the Lexus RX

Lexus RX Reliability And Durability: Pros
YearComment
2013 The strongest advantage of any Lexus over its German competitors isn't how it looks or how it drives, but how long it lasts without becoming a headache. The LS large luxury sedan might be the king here, but the RX also does very well based on our members' Car Reliability Survey responses. For the 2010s, the first model year of the current generation, not a single owner (out of 30 participating) reported a repair during 2012. For the 2004s, the first model year of the second-generation RX, only two out of 29 owners reported a repair. This would be impressive for new cars, much less some that have been driven about 90,000 miles while aging for eight years. One caveat: the 2013 Lexus RX 350 F Sport (and only the F Sport) is the first (and so far only) model equipped with Toyota's new eight-speed automatic transaxle. New transmission designs often have teething issues, which probably explains why Toyota/Lexus is only offering it in a single low-volume application this year. Buy an RX 350 F Sport, and for no additional charge you can beta test the new transmission! We don't have reliability data for the current Cadillac SRX (not quite enough owners have signed up yet), but judging from other GM models one probably would not age as well. I'm giving it the benefit of the doubt by rating the Lexus only "better" rather than "much better." Check the latest Lexus RX reliability stats. full 2013 Lexus RX review
2016 The longer someone intends to keep a car and the higher the priority they place on reliability, the more likely I am to recommend a Toyota or Lexus no matter what I think of the car itself. No other manufacturer has as consistently produced cars that tend to require few repairs for ten-plus years. Cadillac and Lincoln have mixed records. Sometimes their cars are fairly reliable, sometimes they are awful. Previous MKXs have been reliable, but the new one shares little with them. The related 2015-2016 Edge has been pretty good so far. Based on a new platform and with a new engine and a new transmission, the XT5's reliability is entirely unknown. The previous all-new Cadillac, the 2013 ATS, has been troublesome. Risk-averse buyers who prefer the XT5 should wait for the 2018. full 2016 Lexus RX review
