The 2020 U.S. Initial Quality Study is based on responses from 87,282 purchasers in the US and lessees of new 2020 model-year vehicles who were surveyed after 90 days of ownership.
The study, which provides manufacturers with information to facilitate the identification of problems and drive product improvement, was fielded from February through May 2020.
The 2020 study, redesigned for its fifth generation, is now based on a 223-questionnaire covering nine vehicle categories: infotainment; features, controls and displays; exterior; driving assistance (new for 2020); interior; powertrain; seats; driving experience; and climate.
