Fatal crashes in the US
From 2020 to 2023, 19 MR vehicles were involved in crashes on US public roads in which someone died, and 4 people died inside them. These are counts, not crash rates: a model with more cars on the road shows up more often, and people killed outside the vehicle are not counted here.

MACK TRUCKS IS RECALLING CERTAIN MODEL YEAR 2002 THROUGH 2004 CL, CV, LE, MR, RB, RD, AND MODEL YEAR 2003 THROUGH 2004 DM HEAVY TRUCKS MANUFACTURED FROM FEBRUARY 1, 2002 THROUGH SEPTEMBER 30, 2003, EQUIPPED WITH AXLE BEAMS MANUFACTURED BY BHARAT FORGE. THE AXLE BEAM MAY HAVE TRANSVERSE SHEAR LINES ON THE BOTTOM OF THE AXLE FROM THE TRIMMING PROCESS.
MACK IS RECALLING 10,300 MODEL YEAR 2004 AND 2005 CL, CV, DM, LE, AND RB AND MODEL YEAR 2004 RD HEAVY TRUCKS MANUFACTURED FROM OCTOBER 1, 2003 THROUGH SEPTEMBER 30, 2004, EQUIPPED WITH AXLE BEAMS MANUFACTURED BY BHARAT FORGE. THE AXLE BEAM MAY HAVE TRANSVERSE SHEAR LINES ON THE BOTTOM OF THE AXLE FROM THE TRIMMING PROCESS.
MACK IS RECALLING 218 MY 2006-2007 MR TRUCKS. A CHECK VALVE WAS OMITTED FROM THE SECONDARY SUPPLY PORT OF THE SR-7 SPRING BRAKE MODULATING VALVE.
ON CERTAIN TRUCKS EQUIPPED WITH BENDIX SR-7 SPRING BRAKE MODULATING VALVES, THE INTERNAL RUBBER CHECK VALVE MAY LEAK CAUSING A DELAY IN THE APPLICATION OF THE SPRING BRAKES TO PARK THE VEHICLE AFTER THE OPERATOR PULLS THE DASH VALVE BUTTON.
ON CERTAIN TRUCKS EQUIPPED WITH SR-7 BENDIX BRAKE VALVES, THE CHECK VALVE INSIDE THE VALVE CAVITY MAY NOT PROPERLY SET, CAUSING INTERNAL AIR LEAKAGE. IF THE CHECK VALVE DOES NOT PROPERLY SEAT, THE RESULTING LEAKAGE CAN CAUSE A DELAY IN THE APPLICATION OF THE SPRING BRAKES TO PARK THE VEHICLE AFTER OPERATOR PULLS THE DASH VALVE BUTTON.
ON CERTAIN DIESEL POWERED HEAVY DUTY TRUCKS, THE BOLTS ATTACHING THE FUEL TANK MOUNTING BRACKETS TO THE FRAME MAY HAVE INSUFFICIENT TORQUE AND THEREFORE MAY RESULT IN PREMATURE FAILURE OF THE FUEL TANK MOUNTING.
ON CERTAIN HEAVY DUTY CLASS 8 TRUCKS EQUIPPED WITH HOLLAND AIR SUSPENSION SYSTEMS, A TRANSVERSE BEAM CASTING MAY FRACTURE UNDER NORMAL LOADS. IF A CASTING BREAKS WHEN THE VEHICLE IS TRAVELING ON A ROADWAY THERE IS THE POTENTIAL FOR PIECES OF THE CASTING TO BECOME PROJECTILES AND THE SUSPENSION'S TRANSVERSE BEAM MAY DROP DOWN LOW ENOUGH TO CONTACT THE ROAD SURFACE.
ON CERTAIN CLASS 8 CHASSIS BUILT WITH HENDRICKSON LIFT AXLES WHICH CONTAINED WEBB BRAKE DRUMS, THE BRAKE DRUMS COULD EXPERIENCE PREMATURE CRACK OF THE BRAKING SURFACE RESULTING IN REDUCTION OR COMPLETE LOSS OF BRAKING ON THAT WHEEL END OR LOSS OF BRAKE DRUM PIECES.
ON CERTAIN CHASSIS BUILT WITH LNG ENGINES, THE NEXGEN LNG TANK'S PRIMARY AND SECONDARY RELIEF VALVES COULD FAIL TO OPEN AND RELIEVE TANK PRESSURE.
CERTAIN HEAVY DUTY VEHICLES FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 121, "AIR BRAKE SYSTEMS." IMPROPER SEATING OF THE CHECK VALVE RETAINER IN THE BRASS FITTING HOUSING HAS OCCURRED. IT IS POSSIBLE FOR THE AIR BRAKE SYSTEM PRESSURE TO PUSH THE CHECK VALVE INTERNAL PARTS INTO THE PRIMARY SYSTEM RESERVOIR AND A VEHICLE OPERATOR WOULD NOT KNOW THAT THIS HAS HAPPENED.
VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH CERTAIN MERITOR-WABCO BRAKE SYSTEM TWO AND FOUR PORT RELAY VALVES. THE VALVE MAY STICK OPEN WHEN A HIGH-PRESSURE APPLICATION IS RELEASED.
