If you break down on the road, simply call 1-800-866-1177. There is a staff of trained, experienced technicians ready to help. They can help troubleshoot a problem to get you back on the road, arrange to send roadside assistance or arrange for towing to the nearest MACK dealership. One-Call provides personalized service. The person who initially takes your call will be the same person who sees that your situation is resolved quickly and to your satisfaction. If a follow-up call is necessary, the same familiar voice will be on the other end of the line. One-Call technicians can also help you plan ahead to keep your running efficiently by scheduling routine maintenance and lubrication service, or by locating the nearest MACK dealership.
Questions and Complaints Your satisfaction is our most important concern. If questions or complaints arise, first discuss the matter with the service manager at the MACK facility involved. If you are not satisfied with the service manager’s response, contact the branch manager, principal or general manager of the distributorship. If assistance is required at a service dealer, contact the owner of the establishment. If, for any reason, you need further assistance after dealing with the personnel at a MACK subsidiary or distributor, contact the regional service manager at the nearest MACK regional service office. The regional service manager has the responsibility and the authority to recommend action in most cases and (with the aid of relevant district service personnel) will make every effort to conduct a fair review of the situation.
