| # NHTSA Defect Investigations
|
|
|
| Every NHTSA Office of Defects Investigation (ODI) action touching a tracked vehicle — open and historical. The leading indicator of a recall: a Preliminary Evaluation (PE) can escalate to an Engineering Analysis (EA) and then a recall. Includes the recall campaign number for investigations that became recalls.
|
|
|
| ## Columns
|
| | column | meaning |
|
| |---|---|
|
| | `action_number` | NHTSA investigation ID (prefix = type) |
|
| | `type` | PE \| EA \| RQ \| DP \| AQ — investigation stage |
|
| | `status` | open \| closed, per the NHTSA record |
|
| | `make` | Manufacturer (blank if it spans multiple makes) |
|
| | `model` | Model (blank if it spans multiple models) |
|
| | `year_start` | Earliest affected model year in our fleet |
|
| | `year_end` | Latest affected model year in our fleet |
|
| | `component` | NHTSA component under investigation |
|
| | `opened` | Investigation open date |
|
| | `closed` | Close date (blank if open) |
|
| | `recall_campaign` | NHTSA recall campaign # if it led to a recall |
|
| | `nhtsa_url` | Official NHTSA record |
|
|
|
| ## Source & methodology
|
| Parsed from NHTSA’s ODI investigations flat file (FLAT_INV) and matched to our vehicles by year/make/model. One row per NHTSA action number. "status" is open when the federal record carries no close date; "recall_campaign" holds the NHTSA campaign number when the investigation led to a recall. An investigation is NHTSA examining a pattern — not a confirmed defect.
