The Toyota Highlander and the Lexus RX rank the highest for reliability, according to Consumer Reports' most recent reliability study. J.D. Power's 2015 Vehicle Dependability Study of 3-year-old SUVs ranks the Nissan Murano and Lexus RX highest among V-6 mass-market and premium SUVs, respectively.
Consumer Reports ranks corporate siblings Lexus and Toyota first and second in overall reliability in its most recent study, published in October 2014. The study covers model-year 2014 SUVs, but neither model features any significant changes since then.
J.D. Power bases its Vehicle Dependability studies less on speculation and more on actual data from owners who own their cars for three years. Potential buyers should note that the Murano saw a full redesign since the model reported on by J.D. Power, although it shares its basic engine design with the top-rated 2012 SUV.
