NHTSA investigation EA09003 is a Engineering Analysis opened on 2009-01-15 and currently closed. The subject of record is VOLVO VOLVO, which places this file inside the Office of Defects Investigation queue for VOLVO. Latest activity on this investigation was logged on 2010-07-06 — 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 EA09003 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: "EA09-003 is closed with the submission of Volvo's recall 10V-282 recalling approximately 111,034 Model Year (MY) 1998 through 2005 VN and VNL class 8 trucks. Volvo announced recall 10V-282 in response to NHTSA's recall r..." 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 VOLVO files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.

Investigation Summary

EA09-003 is closed with the submission of Volvo's recall 10V-282 recalling approximately 111,034 Model Year (MY) 1998 through 2005 VN and VNL class 8 trucks. Volvo announced recall 10V-282 in response to NHTSA's recall request letter dated June 3, 2010 (available at NHTSA's web site www.safercar.gov). NHTSA found that these vehicles were designed and manufactured with a TRW ball joint that does not meet the combined performance requirements and foreseeable inspection practices of the U.S. market. The ball joint in the steering system that connects the driver's side steering arm/knuckle to the drag link can fail resulting in a total loss of steering on the vehicle. Volvo changed the size and supplier of the ball joint used on these vehicles starting with the 2006 MY vehicles. The failure rates on the vehicles manufactured with the larger ball joint are significantly less than the subject vehicles. The closing of this investigation does not constitute a finding by ODI that no safety defect exists in the vehicles that are not included in Volvo's recall. ODI will continue to monitor the incidence of drag link failures in other MY Volvo trucks. Note: The recall request letter dated June 3, 2010 associated with this investigation describes 49 incidents of ball joint separation. After a comprehensive review of the data it was discovered that the number of separations that NHTSA was aware of was 41 with a failure rate of 36.9 R/100K. The 41 separations resulted in 23 crash allegations.

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.
