NHTSA investigation EA98007 is a Engineering Analysis opened on 1998-03-10 and currently closed. The subject of record is CHRYSLER CHRYSLER, which places this file inside the Office of Defects Investigation queue for CHRYSLER. Latest activity on this investigation was logged on 1999-02-01 - 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 EA98007 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: "NITRILE RUBBER SEALS USED IN THE FUEL RAIL ASSEMBLIES OF THE SUBJECT VEHICLES AT THE SUPPLY, RETURN, AND CROSSOVER TUBE FITTINGS, AND AT THE PRESSURE REGULATOR FAIL, RESULTING IN FUEL LEAKAGE IN THE ENGINE COMPARTMENT. A..." 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 CHRYSLER files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.

Investigation Summary

NITRILE RUBBER SEALS USED IN THE FUEL RAIL ASSEMBLIES OF THE SUBJECT VEHICLES AT THE SUPPLY, RETURN, AND CROSSOVER TUBE FITTINGS, AND AT THE PRESSURE REGULATOR FAIL, RESULTING IN FUEL LEAKAGE IN THE ENGINE COMPARTMENT. ALSO, THE OUTLET (RIGHT) FUEL RAIL MAY LEAK FROM CRACKS AT CERTAIN MOLD GATES IN THE THERMOSET RAIL MATERIAL. CHRYSLER WILL RECALL THE SUBJECT VEHICLES AND STATED THAT IT INTENDS TO REPLACE THE O-RINGS WITH FLUOROCARBON O-RING HAVING GREATER HEAT RESISTANCE CAPABILITY AND ATTACH REINFORCEMENTS TO THE RAIL IN THE AREAS WHERE THE CRACKING CONCERN HAS BEEN KNOWN TO OCCUR MOST FREQUENTLY. RAILS THAT ARE ALREADY CRACKED WILL BE REPLACED BY NEW, REINFORCED RAILS.

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.
