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 (cxu) 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: Fracture of the axle beam can cause a loss of vehicle control, 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: Unintended vehicle movement can increase the risk of a crash.
Risk: Loss of lighting or windshield wiper function can increase the risk of a 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: The improperly heat treated axles may fracture, resulting in a loss of vehicle control and increasing 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: Contamination of the calipers may cause a loss of brakes on one wheel, lengthening the distance required to stop the vehicle, increasing the risk of a crash.
Risk: An inadvertent decoupling of the trailer from the tractor may increase the risk of a crash.
Risk: If the truck unexpectedly requires extra distance to stop, there is an increased risk of a crash.
Risk: If the diaphragm is not completely attached, there may be internal leakage from the service section past the diaphragm, potentially trapping air pressure in the parking brake section. This air pressure in turn, if not vented, may prevent full release of the actuator unit, and may induce brake drag and may result in overheated wheelend service brakes, increasing the risk of a fire.
Risk: If the Automatic Shut-down Protection System does not operate as expected, the operator may be unable to control the increase in the engines rpms, increasing the risk of engine failure and vehicle fire.
Risk: If the ball sockets come loose from the tie rod, a complete loss of steering may result, increasing the risk of a crash.
Risk: If the seat belt detaches from its mounts, the seat belt would fail to properly restrain to the seat occupant, increasing the risk of injury in the the event of a crash.
Risk: If the driver is not warned of something being in the truck's path, there is an increased risk of a crash.
Risk: A failure of the hazard warning lights could reduce the trucks visibility, increasing the risk of a crash.
Risk: Without a pressure relief valve, the air tank could rupture from being overpressurized increasing the risk of injury.
Risk: A blocked reflector makes the truck-tractor less visible when operating the vehicle without a trailer in the dark, increasing the risk of a crash.
