Problems don't follow a 9-to-5 schedule

Which is why every new Mack truck comes with Mack OneCall for around-the-clock roadside assistance anywhere in the United States and Canada. We’ll be there for you when you need it most.

OneCall operators can help you immediately identify the problem and locate your parts from one of our six electronically-linked parts distribution centers in North America. With our next-flight-out services, we can automatically ship the parts you need for overnight delivery even outside of normal working hours, including Sundays and holidays.

Parts will be in the air and you’ll be on the road sooner. And, with over 500 authorized dealers and parts and service locations as well as over 5,000 qualified service facilities in North America, you'll be connected with immediate assistance and OneCall can arrange towing to the closest workshop.

Mack’s warranty protection guarantees you’re never alone. Trained technicians are prepared to provide warranty expertise both inside and outside of your normal dealer area. Which means that no matter where you are, Mack is by your side.
