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.
