Warranty Information

This limited warranty is extended only to the original purchaser of ACDelco products and services from a member of the ACDelco Service Center Program. This limited warranty is made by the Independent Repair Facility ("Facility") who is so named on the original repair invoice and performed the service/repairs on your vehicle using ACDelco automotive parts. This warranty may be honored by other Facilities participating in this program, or other authorized non-participating facilities anywhere in the United States.

The Independent Repair Facility warrants that the above repairs and services performed at their location will be free from defects in materials and workmanship for 12-24 months or 12,000-24,000 miles of use, whichever comes first, measured from the date of the first repair and the odometer reading shown on the original repair invoice. The warranty term depends on the product. This warranty is conditioned on the vehicle being subjected only to normal, non-commercial use, and receiving reasonable and necessary maintenance during the warranty period. Warranty repair costs shall in no case exceed the costs of the original repair or service.

What Is not Covered by This Warranty

You must pay for any non-warranty service you order to be performed at the same time as any warranty service. This warranty will not apply to your repaired vehicle if it has been damaged by abnormal use, misuse, neglect, accident, alteration or "tampering with" (by other than the Facility or Facility employees). The Facilities employees and/or agents do not have authority to modify the terms of this warranty, nor to make any promises in addition to those contained within this warranty. This warranty does not in any way include incidental or consequential damages (additional expenses which you may incur as the result of faulty repair or service). Some states do not allow the exclusion or limitation of incidental or consequential damage, so the above limitation or exclusion may not apply to you. This warranty gives you specific legal rights, and you may also have other rights, which vary from state to state.

This warranty does not cover repair(s) or service(s) except as listed in the section, "What is Covered by this Warranty," even though the Facility may offer other services. Specifically excluded are any battery, engine, transmission, clutch, or differential repairs, associated gaskets and seals, or assembly replacement of the same. Also excluded are auto body, paint, molding, glass repairs, tires, and used parts. Commercial vehicles are excluded.

Magnuson-Moss Warranty Act:
