Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2021 M2 is power train with 2 filings, followed by unknown or other (1) and electrical system (1). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 2 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.

NHTSA currently has 38 investigation files overlapping the 2021 M2. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

20230213POWER TRAIN

Meritor Transfer case has failed due to the internal coating coming off and clogging the oil pump pick up tube screen which starves the oil pump and eventually leads to bearing failure. This is a safety concern because the T-Case is the central connecting point for the drive line. When the bearings fail or seize the torque from the input shaft can cause the connecting components (u-joints, drive shafts) to shake violently and potentially fail, leaving debris in the roadway for other motorists to deal with and also having the potential to damage the trucks brake air system. This could result in an unexpected loss of control by the operator and result in a vehicle crash.

We have had close to 30 failures of the Meritor Transfer Case in both International and Freightliner chassis. This case specifically and of which I will add photos, is a 2021 Freightliner. The internal coating is flaking off and clogging the oil pump pick up screen which in turn starves the pump and eventually leads to bearing failure. This is a safety concern because the T-Case is the central connecting point for the drive line. When bearings fail or seize the torque from the input shaft can cause the connecting components (u-joints, Drive Shafts) to shake violently and potentially fail, leaving debris in the roadway for other motorists to deal with and also having the potential to damage the trucks brake air system.

THIS VEHICLE IS OUTFITTED WITH A BRIDGEPORT AUTOMATED ARM GARBAGE TRUCK BODY. AN ACCIDENT RECENTLY OCCURRED ON 14 APRIL 2021 BECAUSE OF NO WARNING SENSOR ON THE FORKS WITH GRAB THE GARBAGE/RECYCLE CART TO WARN THE DRIVER THAT THE FORKS ARE NOT COMPLETELY RETRACTED AND SAFELY STOW FOR TRANSPORT. A WARNING SENSOR IS ON THE FORK BOOM TO WARN THE DRIVER THAT THE BOOM IS NOT FULLY RETRACTED HOWEVER THIS DOES NOT LET THE DRIVER KNOW THAT THE FORKS ARE STILL A POTENTIAL HAZARD. I REALIZE THAT IT IS THE DRIVER'S RESPONSIBILITY TO KNOW ALL THE ELEMENTS OF HIS TRUCK, HOWEVER DRIVER'S DO MAKE MISTAKES AND IF THE COMPANY SEES A POTENTIAL ISSUES WITH SAFETY BY INSTALLING A WARNING ALARM ON THE BOOM, SIMPLY MOVING IT TO BEHIND THE FORKS WOULD ELIMINATE ANY POSSIBLY DAMAGE/INJURY TO VEHICLES OR BICYCLIST AND PEDESTRIANS.
