Ferrara Fire Apparatus, Inc. (Ferrara) is recalling certain 2004-2012 Inferno and Igniter emergency vehicles, equipped with Timoney Independent Front Suspensions. Inconsistent machining may result in fatigue cracks developing over time in the front axle spindles, causing failure of the spindle and the possible separation of a front wheel from the vehicle.
FERRARA IS RECALLING CERTAIN MODEL YEAR 2009-2011 INFERNO AND IGNITER VEHICLES EQUIPPED WITH MERITOR WABCO ELECTRONIC STABILITY CONTROL (ESC), MANUFACTURED FROM APRIL 2009, THROUGH OCTOBER 2011. THE ESC MODULE MAY CAUSE THE ESC SYSTEM TO ACTIVATE UNNECESSARILY WHEN THE VEHICLE IS DRIVEN IN A PARTICULAR MANNER ON CERTAIN UNIQUE ROAD CONDITIONS AND MAY ADVERSELY AFFECT THE SLIP ANGLE CALCULATION BY THE ESC MODULE.
FERRARA IS RECALLING 89 MODEL YEAR 2008-2009 INFERNO AND IGNITER FIRE TRUCKS EQUIPPED WITH CERTAIN HALDEX QUICK RELEASE VALVES (QRV). THE RUBBER DIAPHRAGM INSIDE THE QRV MAY EXPERIENCE DELAMINATION RESULTING IN SIGNIFICANT LEVELS OF AIR PRESSURE LEAKAGE PAST AND/OR THROUGH THE DIAPHRAGM, OR THE DEVELOPMENT OF A BUBBLE IN THE DIAPHRAGM WHICH MAY TRAP AIR PRESSURE IN THE VALVE AND NOT ALLOW THE SERVICE BRAKES TO RELEASE.
