Complaints by model year
Newer model years have had less time on the road, so they naturally have fewer complaints. Compare a year against its neighbors rather than against brand-new models.

Mack MRU recalls
Risk: Driving without a functioning anti-lock brake system may result in the trailer not braking as intended, increasing the risk of a crash.
Risk: The unexpected release of the parking brake may allow the vehicle to rollaway, increasing the risk of a crash.
Risk: If engine oil comes into contact with a hot surface, there could be an increased risk of a fire.
Risk: A failure of the hazard warning lights could reduce the trucks visibility, increasing the risk of a crash.
Risk: The improper operation of the sensor could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.
Risk: If the latch plate remains partially engaged after the button is pressed, egress from the vehicle could be hindered which would increase the risk of injury in the event of an emergency.
Risk: If the nut comes loose, the hub assembly may separate from the vehicle, increasing the risk of a crash.
Risk: A loss of brake function at one wheel will lead to increased stopping distances and pulling to the left or right when braking, which may increase the risk of a crash.
Risk: If the control box loses ground, it may have localized overheating. This could lead to a vehicle fire.
Risk: In the event of an electrical short, a vehicle fire may result.
Risk: Complete fractures can cause the driver to lose control of the vehicle, increasing the risk of a crash.
Risk: A complete loss of steering may occur increasing the risk of a vehicle crash.
Risk: This can result in seam weld fracture when torque is applied. Once the tube seam weld is fractured, the driveline may become inoperable which may result in a disabled vehicle or debris from the driveline may fall on the roadway, both of which can increase the risk of a crash.
Risk: Slack adjusters with this flow notch could crack under normal braking conditions causing loss of braking which could result in a vehicle crash.
Risk: In the event of an electrical overage, the fuse that should prevent the over current from reaching the mirror switch circuit may fail, such that the mirror switch can overheat. An overheated switch could cause a vehicle fire.
Risk: If the brakes do not perform as they should, a vehicle crash could occur.
