Car reliability ratings There are many. Authoritatives are no longer so many, and J.D research results. POWER among them. But this company explores various verge of reliability, so initially it is worth a reservation, what is Rating J.D. Power US VDS. - These are the results of traditional annual research presented in the American car market for reliability - Vehicle Dependability Study (VDS).
This company explores the quality of cars and is J.D. ratings. POWER INITIAL QUALITY STUDY (IQS). And in both of these ratings, almost the same brands, the same models, but the same positions in the tables of results do not always coincide. Why? The principal difference between these two studies at the age of the test cars.
The IQS study is carried out among car owners after 90 days from the date of acquiring a new car and is meant that the initial quality of cars is estimated. On the subject of the quality of products manufactured by the market, manufacturers (brands), specific enterprises (automobiles) and cars themselves (models) are evaluated.
The VDS study covers cars for three years - and in this case, when drawing up ratings, the term reliability is used. From the point of view of reliability, models, brands and groups of manufacturers are evaluated.
Thus, Rating J.D. Power 2021 US Vehicle Dependability Study VDS demonstrates the ranking of manufacturers and their cars purchased in the US market in 2018, in terms of reliability. Reliability is estimated by the number and nature of the malfunction identified for the 3rd period. In relevant studies, 33,251 the first owners of the 2018 model cars were attended after three years of ownership. The study was conducted from July 2020 to November 2020. The assessment is traditionally displayed in PP100 units - the number of problems per 100 cars. Accordingly, than this index is less, the product is more reliable.
Cars are grouped by categories, brands and manufacturers. In this material, reflect the reliability rating of automakers - which car brands won the reputation of the most reliable in 2021 according to J.D. Power.
Among the brands on reliability criteria with a result of 81 Malfunction per 100 cars in three years of operation leads LEXUS. Ninth once in the last 10 years. In second place Porsche with the index PP100 = 86. Closes the top three leaders of the overall rating and opens the Top Mass Brands KIA with the result of RP100 = 97.
Just one point of the reliability index (RR100 = 98) lagged behind Korean "Japanese" Toyota. And on the fifth-sixth places, leading from the point of view of reliability, representatives of the American auto industry Buick and Cadillac with the same result of exactly 100 malfunctions per 100 cars.
These are leaders. And who are outsiders? The lowest reliability level is recorded from Land Rover: PP100 = 244. The penultimate Alfa Romeo (index 194), the third bottom of Jaguar (186).
What do current results look like from last year? The Organizing Committee summarizes that "the reliability of vehicles increased to the highest level in history (studies that are held since the 70s of the last century - ed.): The average industry is 121 PP100 - the lowest indicator for the entire study history - Improvement at 13 PP100 (10%) compared to 134 PP100 in 2020. "
A vice president of the global automotive industry company J.D. Power Dave Sargen noted: "Today's three-year-old cars are higher and more reliable than in previous years. Most owners do not face that their cars break or fall apart, but for many modern automotive technologies continue to work badly or not entirely as they expect, and it is also considered not enough reliability. This affects their overall opinion about the car. In the future, reliability will be partially determined by the ability to solve problems by updating vehicles and prevent technology obsolescence. "
