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 Pinnacle (chu) recalls
Risk: A separated hubcap can create a road hazard, increasing the risk of a crash.
Risk: A vehicle that drifts out of its lane increases the risk of a crash.
Risk: If the drag link separates, loss of steering control my occur, increasing the risk of a crash.
Risk: If the reflectors are blocked, the vehicle's visibility to other drivers may be reduced, increasing the risk of crash.
Risk: The undersized air brake supply reservoir may provide an insufficient air supply to properly operate the brakes during repetitive brake applications, reducing braking performance and increasing the risk of a crash.
Risk: If the mirror detaches from the door, the mirror may strike another vehicle or pedestrian, increasing the risk of injury or crash.
Risk: If the tie rod loosens, it may disconnect from the steering knuckle, causing a complete loss of steering, increasing the risk of a crash.
Risk: Overloaded front wheel hubs can result in premature failure of the hubs, bearings, and the related components, which can cause the front hub assembly to separate from the front axle. Because of this, the driver may lose control of the vehicle or parts may be dropped on the road, increasing the risk of a crash.
Risk: Partial tread separation can increase the risk of a crash.
Risk: If he cap nut loosens and falls off, the yoke can separate from the axle input shaft and allow the drive shaft to disconnect, increasing the risk of a crash.
Risk: If the fifth wheel and locking mechanism are sufficiently damaged, the locking mechanism may fail to operate as intended and the trailer may unexpectedly detach from the tractor, increasing the risk of a crash.
Risk: If the electrical cables and air lines were to fall and get tangled in the driveline, it could affect the electrical system and braking system, increasing the risk of a vehicle crash.
Risk: A failure of the hazard warning lights could reduce the trucks visibility, increasing the risk of a crash.
Risk: Deposits of contaminants may result in the circuits being bridged, creating a high resistance short, increasing the risk of a fire.
Risk: If this occurs, under certain driving conditions the driver's visibility will be reduced, increasing the risk of a crash.
Risk: If the weld fails, the pedal shaft may work its way loose and potentially cause the clutch pedal to fall to the floor, which would limit the driver's control of the vehicle increasing the risk of a 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: The bolts may fail and could result in the fifth wheel coming loose causing the trailer to separate from the tractor increasing the risk of a crash.
Risk: Lack of reflectors could lead to reduced visibility of the vehicle increasing the risk of a crash.
