Isuzu's Commitment to You

We are committed to assuring your satisfaction with your new Isuzu Medium Duty Truck.

Your Isuzu Medium Duty Truck 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 Isuzu Medium Duty Truck dealer is best equipped to provide all of 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, Isuzu and/or Isuzu Medium Duty Truck 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, see Owner Assistance .

We thank you for choosing an Isuzu Medium Duty Truck.

Warranty Service - United States

While any authorized dealer handling your model series will perform warranty service, we recommend that you return to the authorized dealership that sold you your vehicle because of its continued and personal interest in you. If you are traveling or have moved, or did not obtain your truck from an authorized dealer, visit any authorized dealer handling your model series in the United States for warranty service. Allison Transmission® service is provided by authorized Allison Transmission dealers. Diesel engine service for the Isuzu 6H engine can be obtained from Isuzu diesel engine service centers that include most Isuzu Medium Duty dealers. In case you require assistance in locating a dealer to perform service on your Isuzu Medium Duty Truck, refer to the Owner Relations toll-free telephone under Owner Assistance for more information.
