What’s a good way to buy a problem-free car or light truck? You might start by poring through expert evaluations in car-buff magazines or asking a friend who has experience with a car brand that interests you. The latest J.D. Power Initial Quality Study (IQS) is yet another excellent source of information about the most reliable vehicles.
For more than 30 years, the consumer-research firm has queried new-car buyers about their purchases after 90 days of ownership and again after three years of ownership. As it turns out, the 90-day IQS is a good predictor of three-year dependability. For 2020, more than 87,000 owners participated in the IQS.
