Fatal crashes in the US
From 2020 to 2023, 56 MRU vehicles were involved in crashes on US public roads in which someone died, and 6 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.

Recalls
18 campaigns cover the MRU; the latest 12 are below.
Mack Trucks, Inc. (Mack) is recalling certain 2010-2018 MRU and 2019-2025 Terrapro towing vehicles. The vehicles are missing the anti-lock brake (ABS) warning light and circuitry that controls the anti-lock brake function for an attached trailer. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."
Mack Trucks, Inc. (Mack) is recalling certain 2008-2019 TerraPro (MRU) and 2019-2022 TerraPro (TE) vehicles. A brake control valve air leak into the attached exhaust hose can create excessive back pressure, causing the parking brake to release unexpectedly.
Mack Trucks, Inc. (Mack) is recalling certain model year 2011-2016 Mack MRU and LEU trucks manufactured June 25, 2010, to April 30, 2015, and 2015-2016 LR6 trucks manufactured from December 18, 2014 through March 6, 2015. Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.
Mack Trucks Inc. (Mack) is recalling certain model year 2010-2014 CHU, CXU, and MRU, 2007 CT and CV, 2008-2014 GU, and 2011-2014 LEU, and TD trucks manufactured February 28, 2006, through November 8, 2013, and equipped Hamsar Electronic Flasher. The hazard warning lights may fail.
Mack Trucks Inc. (Mack) is recalling certain model year 2014-2015 CXU, 2010-2015 LEU, and 2011-2015 MRU vehicles manufactured with certain Cummins Westport Model ISL G and ISX12 G engines. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.
Mack Trucks, Inc. (Mack) is recalling certain model year 2014 CXU and MRU trucks manufactured August 12, 2013, through October 9, 2013 and equipped with IMMI-brand L9 seat belt buckles. When the button is pressed to release the seat belt, the latch plate can become partially engaged with the buckle, making the seat belt difficult to unlatch. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 209, "Seat Belt Assemblies."
Mack Trucks is recalling certain model year 2013-2014 CHU, CXU, GU, LEU, and MRU vehicles manufactured with pro-torque axle spindle nuts from August 28, 2012, through August 16, 2013. The pro-torque nut may not have been installed correctly, which may result in a loosening of the nut.
Mack Trucks, Inc. is recalling certain model year 2013-2014 CHU, CXU, GU, MRU, and LEU trucks manufactured July 16, 2012, through march 18, 2013 and equipped with drum brakes. The clevis pin for the brake slack adjuster may be missing a cotter pin. If the cotter pin is not installed, the clevis pin may loosen and fall out causing a loss of brake function on the affected wheel.
Mack Trucks is recalling certain model year 2008-2009 GU, LEU, and MRU trucks, manufactured from December 12, 2007, through May 8, 2008 and equipped with a certain focal mounted retarder control box. The control box may lose its electrical ground.

ON THESE VEHICLES THE ALTERNATOR GROUND CABLE RUNS DIRECTLY TO THE STARTER, WHICH DEFEATS THE CIRCUIT PROTECTION.
MACK IS RECALLING CERTAIN MODEL YEAR 2009-2011 MRU AND MODEL YEAR 2010-2011 LEU VEHICLES, MANUFACTURED FROM JANUARY 1, 2009, THROUGH SEPTEMBER 30, 2010 BECAUSE THE FRONT AXLE MAY CRACK AND FRACTURE.
MACK TRUCKS IS RECALLING CERTAIN MODEL YEAR 2009-2012 MRU HEAVY TRUCKS MANUFACTURED FROM NOVEMBER 26, 2008, THROUGH APRIL 26, 2011.
