The United States is a significant market for car manufacturers, but reliability varies widely among brands. Explore the interactive graphs below to see how different car brands rank in terms of reliability and compare their performance against each other.
How reliability is measured
Reliability is measured by the number of problems per 100 vehicles (PP100) .
What is PP100?
PP100 is a metric used by J.D. Power to measure the number of problems per 100 vehicles (PP100) in a given year. The lower the PP100, the more reliable the brand.
What data is collected?
The data is collected from the J.D. Power Vehicle Dependability Study, which surveys owners of 3-year-old vehicles to determine the number of problems they've experienced in the past 12 months.
The study, now in its 35th year, covers 184 specific problem areas across nine major vehicle categories: climate; driving assistance; driving experience; exterior; features/controls/displays; infotainment; interior; powertrain; and seats.
Important!
This only accounts for the number of problems reported by original owners after 3 years of ownership, without considering consumer sentiment, satisfaction, or any other factors.
