Reliability by generation

Are new cars more reliable? Same brands, different generations

Every car here was checked at the same point in its life — 5–10 years old — so a 2012 model inspected back then and a 2018 model inspected recently compare fairly. Across all brands the answer is humbling: the share still in good condition has barely moved between generations (~55–60%). Cars overall aren't getting better or worse — but individual brands moved a lot, in both directions.

Blue = share of that brand's cars scoring 60+/100 when we inspected them at 5–10 years old, by model-year generation; the dashed grey line is the all-brand average. Because newer generations are inevitably inspected at the younger end of that window, every point is age-adjusted to a typical 7½-year-old using the decline we measure in our own data (5.5 points per year of age). Each point covers at least 15 cars — hover a dot for the sample. Brands appear once three generations have enough data, and the newest generation splits into its own column as inspections accumulate — the chart grows on its own. One honest caveat: a brand's model mix shifts between generations, and the newest generation's high-mileage story isn't written yet.

FAQ
?
Are new cars more reliable than older ones?
Not as a whole. Comparing cars at the same age (inspected at 5–10 years old), about 66% of the newest generation is in good condition — essentially the same share as generations from a decade earlier. Individual brands, though, moved a lot in both directions.
?
Which brands are improving?
Audi, Volkswagen, BMW, Lexus, Mercedes, Ford, Toyota, Hyundai show newer generations holding up clearly better at the same age.
?
Which brands are slipping?
Chevrolet score lower in their newer generations than they did in the early 2010s — worth knowing before paying a premium for the badge's old reputation.
