What a recall is
- Safety recall
- A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
- Safety investigation
- NHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
- Manufacturer communication
- Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
Safety investigations
NHTSA inquiries naming this vehicle. An investigation is not a finding of a defect, and it is not a recall.
WELD SEPARATION
THIS INVESTIGATION WAS OPENED AS THE RESULT OF A REPORT ALLEGING THAT AN ARTICULATING BUS OWNED BY THE CHICAGO TRANSIT AUTHORITY (CTA) HAD EXPERIENCED A WELD FAILURE AT THE ARTICULATION JOINT OF THE BUS.IN EARLY APRIL, ODI AND VRTC ENGINEERS VISITED WITH THE CTA AND CONFIRMED THE FAILURE ALLEGATION. THE SEPARATION OF THE NABI ARTICULATING BUS WAS THE RESULT OF A WELD FAILURE THAT OCCURRED IN THE PARENT METAL OF THE ROLLED PLATE BRACKET. THE FRACTURE OCCURRED JUST BEYOND THE WELD LINE WHERE THE BRACKET IS WELDED TO THE ARTICULATING JOINT CASTING.THE FATIGUE FRACTURE APPEARED TO BE CAUSED BY TORSIONAL FORCE LOADING THROUGH THE JOINT CONFIGURATION.BENDING MOMENT FATIGUE INITIATED THE FRACTURE CAUSED BY FORE AND AFT ROTATIONAL LOADING THAT COULD BE GENERATED BY, AMONG OTHER FORCES, BOTH POSITIVE AND NEGATIVE WHEEL TORQUE (ACCELERATION AND BRAKING).A VISUAL EVALUATION OF THE SURROUNDING STRUCTURE SUGGESTS THAT SEVERAL WELDED MEMBERS FORM A BOX BEAM AND ARE INTENDED TO REACT TO THE TORQUE AND PREVENT THE MAIN STRUCTURAL WELD FROM BENDING, BUT THE UN-REINFORCED MATERIALS APPEAR TO BE INADEQUATE FOR THE FORCES GENERATED IN THIS APPLICATION. ON APRIL 16, 2009, NABI IDENTIFIED A DEFECTIVE WELDED CROSSMEMBER ASSEMBLY IN THE UNDERSTRUCTURE OF THESE BUSES.AFTER FURTHER EVALUATION, NABI DECIDED TO FILE A DEFECT REPORT WITH THE AGENCY. NABI WILL ARRANGE TO INSPECT AND REPAIR ALL AFFECTED BUSES, INCLUDING INSTALLATION OF ADDITIONAL REINFORCEMENT TO THE AFFECTED AREAS.THIS RECALL ACTION RESOLVES THE ISSUES RAISED BY THIS INVESTIGATION. ACCORDINGLY, THIS INVESTIGATION IS CLOSED.
