Lexus received a combined four segment awards in the 2011 J.D. Power and Associates Initial Quality Study (IQS) and has earned the honor of being the highest ranking nameplate in the industry.

Lexus ranked highest among all nameplates in the 2011 IQS with 73 problems per 100 vehicles (PP100). Lexus has ranked highest in the IQS study in 13 of the last 22 years, beginning with the brand's first model year in 1990.

Lexus captured four segment awards in this year's study, more than any other premium brand. These awards include the Lexus ES 350 for Entry Premium car; the Lexus GS for Midsize Premium Car; the Lexus GX 460 for Midsize Premium Crossover/SUV; and the Lexus LS 460 for Large Premium Car. The Lexus GS and GX 460 rank highest in their respective segments for a third consecutive year. The Lexus LS earned the distinction of highest-performing model in the industry for a second consecutive year with fewest quality problems in the industry, with just 54 PP100.
