Each month, HDT brings you a recall roundup of heavy-duty truck and trailer recalls announced by the National Highway Traffic Safety Administration. Following are recalls from June 2023.
NHTSA recalls involve vehicles that may create a safety risk. If left unrepaired, the agency explained, a potential safety defect could lead to injury or even death. Safety defects must be repaired by a dealer at no cost to the vehicle owner.
Stay informed and ensure the safety of your fleet, especially if you have Navistar, Wabash, Mack, or Volvo vehicles in your lineup.
