NHTSA Engineering Analysis EA99029 — closed, opened 1999-09-30 and involving the MAZDA PROTEGE.
NHTSA investigation EA99029 is a Engineering Analysis opened on 1999-09-30 and currently closed. The subject of record is MAZDA PROTEGE, which places this file inside the Office of Defects Investigation queue for MAZDA. Latest activity on this investigation was logged on 2000-05-10 — 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 EA99029 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: "IN ITS LETTER DATED APRIL 21, 2000, MAZDA STATED THAT IT WILL CONDUCT A SAFETY RECALL OF APPROXIMATELY 79,000 MODEL YEAR 1995 AND 1996 MAZDA PROTEGE VEHICLES BUILT FROM JUNE 1994 THROUGH JULY 1995. MAZDA DEALERS WILL REP..." 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 MAZDA 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.
