1 Associated Investigation
Alternator Front Bearing Failure
NHTSA ID: PE21011
Dated opened: May 13, 2021
NHTSA’s Office of Defects Investigation (ODI) is opening a Preliminary Evaluation after receiving a tip from a fleet safety manager concerning alternator front bearing failures that cause elevated temperatures within the engine compartment, resulting in the fire suppression system (FSS) activating, immediately shutting the engine down, and rendering the bus inoperable.
Review of Early Warning Reporting Data identified 9 field reports for Model Year (MY)2015 through MY2019 H3 and X3 Prevost buses, describing alternator failures in any of 3 alternators equipped on the bus. In some cases, a minor fire occurred damaging nearby electrical harnesses.
An immediate shut down of the bus can increase the risk of a crash or injury of passengers when transferring to another bus.
ODI is opening this investigation to evaluate the cause, consequence, scope and frequency of the alleged defect in the subject Prevost buses.
