IHS Automotive division Polk reported that General Motors had the highest 2015 U.S. customer loyalty of any automaker, while Ford had the highest customer loyalty for a particular brand (likely due to the F-series).

Jeep, on the other hand, led conquests among all brands; Audi won this disinction in 2014.

Within segments, three Jeeps did well in loyalty: Renegade, grand Cherokee, and Wrangler.  Chrysler grabbed one spot, for the Town & Country (despite a recent drubbing by Consumer Reports.)

GM won three segments as well; Ford had two; Toyota garnered four, three for Lexus and one for Toyota itself. Honda had just one, for an Acura.  Overall, 52% of returning customers stuck to the same brand as their prior car, and 59% stayed with the same automaker.
