NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE03-005.
try.vin does not copy NHTSA's investigation documents; NHTSA's investigation record lists the ones NHTSA has published.
CERTAIN 1998-2001 FREIGHTLINER CENTURY AND COLUMBIA VEHICLES EXHIBIT A HIGHER RATE OF FRONT BRAKE AIR HOSE LEAKS THAN EARLIER VINTAGE FREIGHTLINER VEHICLES.THE LEAKS HAVE BEEN FREQUENTLY DISCOVERED AT FMCSA ROADSIDE INSPECTIONS SINCE THESE INSPECTIONS ARE CONDUCTED WITH THE BRAKES APPLIED (PRESSURIZING THE AIR HOSE) WHEREAS DRIVER PRE-TRIP INSPECTIONS MAY NOT ALWAYS BE PERFORMED WITH THE BRAKES APPLIED. AFTER A THOROUGH TECHNICAL REVIEW OF THIS MATTER,ODI HAS CONCUDED THAT WHILE THE SUBJECT VEHICLES EXHIBIT A HIGHER RATE OF FRONT BRAKE AIR HOSE LEAKS THAN EARLIER VINTAGE AND PEER VEHICLES, THESE LEAKS APPEAR TO BE MINOR. FREIGHTLINER HAS EXTENDED THE WARRANTY FOR THIS COMPONENT TO 5 YEARS, 500,000 MILES AND WILL ASSIST IN ALERTING THOSE VEHICLE OWNERS WHOSE VEHICLES ARE MOST SUSCEPTIBLE TO FRONT BRAKE AIR HOSE LEAKAGE BY ISSUING A SERVICE BULLETIN ALERTING THOSE OWNERS TO THE POTENTIAL FOR FRONT BRAKE AIR HOSE LEAKAGE TO OCCUR.

Vehicles and equipment listed for this investigation
NHTSA's investigations file lists these vehicles and equipment for Preliminary Evaluation PE03-005. A listed model year means only that an investigation names it; it says nothing about any particular vehicle. Model years with a try.vin recall page link to that page's NHTSA investigations section.
What 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.
