NHTSA Engineering Analysis EA86031 - closed, opened 1986-09-12 and involving the NISSAN NISSAN.
NHTSA investigation EA86031 is a Engineering Analysis opened on 1986-09-12 and currently closed. The subject of record is NISSAN NISSAN, which places this file inside the Office of Defects Investigation queue for NISSAN. Latest activity on this investigation was logged on 1987-04-27 - NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
An Engineering Analysis like EA86031 is the deeper technical phase that follows a PE. NHTSA requests design, warranty, and field-failure data from the manufacturer, conducts its own testing when needed, and determines whether the evidence supports a safety defect finding that would compel a recall.
Investigators summarized the matter as follows: "SUMMARY OF INFORMATION FROM MANUFACTURER: ALL PROBLEM REPORTS INVOLVE NISSAN BASED MICRO-MINI MOTORHOMES. ROCKWOOD REPORTEDLY HAS 6 SEAT- BELTED POSITIONS.ANALYSIS: VEHICLES APPEAR TO BE OVERLOADED AND USE THE ONE PIECE..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related NISSAN files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.

About This Investigation Type
An Engineering Analysis (EA) is the in-depth phase following a Preliminary Evaluation. NHTSA engineers conduct testing, collect data from manufacturers, and perform detailed technical analysis to determine whether a safety defect exists. An EA may lead to a voluntary recall by the manufacturer or, in rare cases, a mandatory recall order.
