Complaints submitted to NHTSA by owners; unverified reports, one complaint can name several components. Complaint counts are not normalized by sales; compare years of the same model, not different models. EPA annual fuel cost uses EPA's current fuel price assumptions, not the price when the car was new. Horsepower is the rating listed for EPA test vehicles. Dimensions are Canadian-market specifications and can differ slightly from US models.
