What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2007 Orion Vii, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

FOLLOWING AN INVESTIGATION BY A FORENSIC ENGINEER WITH EXTENSIVE EXPERIENCE IN DIESEL FIRES, IT WAS DETERMINED THAT THE PROBABLE CAUSE OF THE FIRE WAS THE WEAR AND SHORTING OF WIRES FROM THE ALTERNATOR THAT WERE CHAFFING ON THE #5 CYLINDER DIESEL INJECTOR LINE. UPON REMOVAL IT WAS DISCOVERED THAT THE LINE WAS MELTED AND A HOLE BURNED THROUGH THE STEEL TUBE ALLOWING THE SPRAYING OF HIGH PRESSURE DIESEL FUEL. UPON INVESTIGATING OTHER BUSES OF THE SAME MANUFACTURING GROUP APPROXIMATELY 15 OUT OF 17 BUSES DISPLAYED AT LEAST SOME WEAR, AND 7 HAD PHYSICAL GROOVING ON THE INJECTOR LINE. *TR
