On certain trucks, the automatic high beams may not switch to low beams automatically. As a result, the trucks may not meet certain requirements of Canadian regulations.
Safety Risk
High beams that stay on could cause glare for oncoming drivers and increase the risk of a crash.
Corrective Action
To reduce the safety risk, Mack recommends you switch manually between the low beams and high beams until the recall repairs have been completed. Mack will notify owners by mail and advise you to take your vehicle to a dealership to update the vehicle software.
