Critical patterns are car-killers. Engine, transmission, or structural failures that decide whether a vehicle is worth keeping.
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.

This is the documented dollar range we see across affected vehicles. Quotes outside this band — high or low — get flagged in a Verdict.
Verified
What the engine requires before applying the full deduction. “Verified” means documented symptom or service record — not an unverified shop claim, not a forum post.
Base deduction−8 on the 0–100 scale.
Past-window credit30% credit back if the vehicle has aged past the window without symptoms.
Each entry traces to documented sources — recall bulletins, regulator complaints, manufacturer service bulletins. Not forum chatter.
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.
