Population range — not a quote for your car.
Engine & powertrain
Pistons, rings, gaskets, oil consumption, fuel dilution, turbos, intake systems — the patterns that decide whether an engine makes it to 250k.
Major patterns are wallet events — repairs in the four-figure range that re-shape the math on a quote or a purchase decision.
Most affected vehicles hit this failure inside the window below. Plan for it.
Vehicles outside this population may exhibit the same symptoms for unrelated reasons. The engine resolves down to your specific VIN before applying this pattern to a Verdict.
The window above is where most documented failures cluster. Vehicles past the tail aren’t immune — but they’ve statistically aged out of the high-density band.
A symptom matching this list isn’t a diagnosis — it’s a flag. The Verdict engine cross-checks symptoms against your VIN’s recall history and the failure window to weigh the probability.
If any of these have been performed on the affected vehicle, the engine reduces the failure-mode deduction accordingly. Documentation matters — “the previous owner said” isn’t the same as a receipt.

The encyclopedia tells you what’s documented across the population. The Verdict tells you what it means for your specific year, mileage, and recall status.
