GuardDog Connect gives you a copilot that’s dedicated to keeping you on the road. It connects your truck to a 24/7 network of support staff and repair centers. If something happens to your truck on the road, GuardDog Connect detects the problem instantly and calls it in—usually, before you can tell that anything’s wrong. If the issue needs immediate attention, it contacts Mack’s OneCall™ customer center with the fault code. A team of experienced technicians evaluates the fault code and identifies the exact issue and repairs needed. The driver is then instructed where to take the truck. Upon arrival, the dealer and technicians can get right to work since OneCall, through MACK® ASIST, has forwarded all the necessary information, including parts needed, service instructions and diagnostic information to get you back on the road faster.

As an extension of our Pedigree Uptime Protection integrated customer support platform, GuardDog Connect makes sure that your MACK is the most dependable truck on the road.  If you have any questions regarding GuardDog Connect, then please call 1-800-866-1177, or email
