It wasn't by much. It's just notable because people don't expect U.S. or Korean car reliability but both had car companies that did well.

It's only based on data so sure.

It's based purely on reported repair data of the three most current years of ownership.

@Biosteelman I just read the chart. All of my toyotas, lexus and Honda sedans hit 250 think with no repairs. My gm brands never made 100.

@Bigwavedave it is only recent cars not a historical look. Specifically the current model owned for 3 years as the benchmark

@Biosteelman terrible criteria imo

@Bigwavedave then you should use the Consumer Reports guide that is based on lifetime ownership but limited to a pool of CR customers.
I think they both have merit. The JD Power is great for detecting marginal changes and future expected short run longevity but the C.R. Is good for a historical reference and a long term view. It should be noted within the report itself it said the variance of dependability has narrowed greatly amongst car brands.
