The satisfaction and goodwill of the owners of Detroit Diesel engines are of primary concern to the Detroit Diesel Allison
Division, its distributors and their dealers.
Normally, any problem that arises in connection with the sale or operation of your engine will be handled by the
distributor or dealer in your area. It is recognized, however, that despite the best intentions of everyone concerned,
misunderstandings may occur. If you have a problem that has not been handled to your satisfaction, we suggest that you
take the following steps:
Step One - Discuss your problem with a member of management from the distributorship or dealership.
Frequently complaints are the result of a breakdown in communication and can quickly be resolved by a member of
management. If you have already discussed the problem with the Sales or Service Manager, contact the General
Manager. If your problem originates with a dealer, explain the matter to a management member of the distributorship
with whom the dealer has his service agreement.
Step Two - When it appears that your problem cannot readily be resolved at the distributor level without additional
assistance, contact the Detroit Diesel Allison Regional Office nearest you listed below:
