NHTSA Engineering Analysis EA06001 — closed, opened 2006-01-20 and involving the CADILLAC CADILLAC.
NHTSA investigation EA06001 is a Engineering Analysis opened on 2006-01-20 and currently closed. The subject of record is CADILLAC CADILLAC, which places this file inside the Office of Defects Investigation queue for CADILLAC. Latest activity on this investigation was logged on 2006-12-01 — 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 EA06001 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: "ODI'S INVESTIGATION OF THE CADILLAC SRX GLASS ROOF DID NOT IDENTIFY ANY DEFECTIVE MANUFACTURING PROCESS, DESIGN, OR QUALITY CONTROL ISSUE WITH THE SRX GLASS ROOF SYSTEM. GM BELIEVES THAT THE MOST LIKELY CAUSE OF BREAKAGE..." 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 CADILLAC files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.
Investigation Summary
ODI'S INVESTIGATION OF THE CADILLAC SRX GLASS ROOF DID NOT IDENTIFY ANY DEFECTIVE MANUFACTURING PROCESS, DESIGN, OR QUALITY CONTROL ISSUE WITH THE SRX GLASS ROOF SYSTEM. GM BELIEVES THAT THE MOST LIKELY CAUSE OF BREAKAGE IS STONE OR SHARP OBJECT IMPACT AGAINST THE GLASS. THE INVESTIGATION INCLUDED A PEER MULTI-VEHICLE ANALYSIS. THAT ANALYSIS FOUND THAT OTHER VEHICLES WITH LARGE GLASS ROOF SYSTEMS EXPERIENCE RANDOM STONE/OBJECT IMPACTS AND BROKEN GLASS PANELS. THE INCIDENT RATE FOR THE SUBJECT VEHICLES DID NOT STAND OUT IN THIS ANALYSIS. THE SRX ULTRAVIEW POWER GLASS ROOF CONSISTS OF UP TO THREE TEMPERED GLASS PANELS SURROUNDED BY METAL TRIM AROUND THE PERIMETER OF THE ROOF STRUCTURE. THE MAIN FRONT PANEL IS A LARGE MOVABLE GLASS PANEL RESIDING OVER THE FIRST AND SECOND ROW OCCUPANTS. THE MIDDLE NON-MOVABLE PANEL IS NOT ACCESSIBLE FROM THE INSIDE. THE REAR NON-MOVABLE PANEL IS AN OPTIONAL PANEL (ULTRAVIEW PLUS OPTION) AND IS VIEWABLE FROM THE INSIDE. A SAFETY-RELATED DEFECT HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED. ACCORDINGLY, THIS INVESTIGATION IS CLOSED. THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST. THE AGENCY WILL MONITOR THIS ISSUE AND RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES. SEE SUMMARY REPORT FOR ADDITIONAL INFORMATION.
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.
