OneCall Complete Care

OneCall™ proves that nothing slows down a Mack® truck. Dedicated Mack dealers are available to deliver round-the-clock roadside assistance and diagnose problems with your truck before they happen. Mack cares for you so you can take care of your customers.

GuardDog Connect

GuardDog® Connect delivers a copilot dedicated to protecting you on the road. Using real-time diagnostics and monitoring, GuardDog Connect detects issues facing your vehicle and instantly calls it in for analysis—usually before the driver even knows there’s an issue.

Extended Service Intervals

With a focus on reducing the total cost of ownership for customers, Mack Trucks is extending service intervals for diesel particulate filters (DPFs) and diesel engine oil and filter changes on all model year 2011 and newer Mack® models powered by Mack MP7®, MP8® or MP10® engines.
