HUMMER's Commitment to You

We are committed to assuring your satisfaction with your new HUMMER.

Your HUMMER dealer also wants you to be completely satisfied and invites you to return for all your service needs, both during and after the warranty period.

Owner Assistance

Your HUMMER dealer is best equipped to provide all your service needs. Should you ever encounter a problem that is not resolved during or after the limited warranty period, talk to a member of dealer management. Under certain circumstances, GM and/or GM dealers may provide assistance after the limited warranty period has expired when the problem results from a defect in material or workmanship. These instances will be reviewed on a case-by-case basis. If your problem has not been resolved to your satisfaction, follow the "Customer Satisfaction Procedure" as outlined under Owner Assistance .

We thank you for choosing a HUMMER.

GM Participation in an Alternative Dispute Resolution Program

See the "Customer Satisfaction Procedure" under Owner Assistance for information on the voluntary, non-binding Alternative Dispute Resolution Program in which GM participates.

Warranty Service - United States and Canada

Your selling dealership has made a large investment to ensure that they have the proper tools, training, and parts inventory to make any necessary warranty repairs should they be required during the warranty period. We ask that you return to your selling dealer for warranty repairs. In the event of an emergency repair, you may take your vehicle to any authorized GM dealer for warranty repairs. However, certain warranty repairs require special tools or training that only a dealer selling your brand may have. Therefore, not all dealers are able to perform every repair. If a particular dealership cannot assist you, then contact the Customer Assistance Center. If you have changed your residence, visit any HUMMER dealer in the United States or Canada for warranty service.
