Are GM Accessories covered under my vehicle’s warranty?
If the GM Accessory was installed prior to taking delivery (at the time of purchase), it will be covered under the applicable new vehicle warranty (Bumper-to-Bumper, Powertrain, etc.).
If the GM Accessory was installed after vehicle delivery, or replaced under the New Vehicle Limited Warranty, it will be covered, parts and labor, for the balance of the applicable portion of the New Vehicle Limited Warranty, but in no event less than 12 months/unlimited miles.
GM Accessories sold over the counter, or those not requiring installation, will receive the standard GM Dealer Accessory Warranty of 12 months from the date of purchase, parts only. GM Licensed and Integrated Business Partner (IBP) Accessories are covered under the accessory-specific manufacturer's warranty and are not warrantied by GM or its dealers.
