NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE10-028.
ODI opened this investigation based on EWR data indicating that a front air brake hose could rub the tire and eventually develop an air leak.
Volvo's IR response and ODI's investigative review revealed no sudden loss of air events. Rather abrasion of the hose was being noted. Additionally no crashes or injuries were reported.
An analysis of the warranty data with respect to time in service and miles to failure did not indicate that the subject vehicles were experiencing failures at a rate higher than peer vehicles. The subject vehicles are commercial vehicles.
The front air brake hoses are easily visible and accessible during routine inspections.
The failure mode is a slow abrasive process that occurs over time.
ODI's review indicates that it is unlikely that the alleged defect would go undetected.
Additionally, Volvo has issued two notices to dealers and authorized service stations alerting them to look for the alleged defect (abrasion on the air hose) in the subject vehicles.
A safety related defect trend has not been identified at this time and further use of agency resources does not appear to be warranted.
The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.
The agency reserves the right to take further action if warranted by the circumstances.
Vehicles and equipment listed for this investigation

All Volvo recallsWhat an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
