NHTSA Engineering Analysis EA03003 - closed, opened 2003-04-09.
NHTSA investigation EA03003 is a Engineering Analysis opened on 2003-04-09 and currently closed. The subject is tracked inside the Office of Defects Investigation queue. Latest activity on this investigation was logged on 2004-03-03 - 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 EA03003 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: "THIS INVESTIGATION WAS DERIVED FROM INFORMATION GATHERED DURING PE02-046, BOSCH DISC BRAKE CALIPERS. THIS INVESTIGATION FOCUSED ON THE VEHICLE MANUFACTURER, NEWMAR. SUBJECT VEHICLES WERE THOSE BUILT WITH A HYDRAULIC BRAK..." 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.
Investigation Summary
THIS INVESTIGATION WAS DERIVED FROM INFORMATION GATHERED DURING PE02-046, BOSCH DISC BRAKE CALIPERS. THIS INVESTIGATION FOCUSED ON THE VEHICLE MANUFACTURER, NEWMAR. SUBJECT VEHICLES WERE THOSE BUILT WITH A HYDRAULIC BRAKE SYSTEM INCORPORATING THE BOSCH ZERO OFFSET PIN SLIDE (ZOPS) CALIPERS. ODI'S CONCERN WAS EXCESSIVE WHEEL END HEAT, POSSIBLY RESULTING IN A WHEEL END FIRE. DURING THE INVESTIGATION, ODI DISCOVERED TWO SPECIFIC NEWMAR VEHICLE MODELS, THOSE BUILT ON NEWMAR CHASSIS AND THOSE BUILT ON A WORKHORSE CHASSIS. AS A RESULT OF THE AGENY'S INVESTIGATION INTO THIS MATTER, ALL NEWMAR OWNERS WILL BE NOTIFIED (04V-019) AND THE REMEDY WILL BE APPLIED TO THEIR VEHICLES. SOME NEWMAR VEHICLES (1,795) BUILT ON THE WORKHORSE CHASSIS ARE BEING RECALLED BY WORKHORSE (04V-084). THIS INVESTIGATION IS CLOSED. FURTHER DETAILS ARE PROVIDED ON PAGES 2, 3, AND 4. COPIES OF BOTH SAFETY RECALLS ARE ATTACHED.
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.
