OnStar Rewards is a mobile application developed by Maritz LLC for non-GM dealership personnel to submit claims for the OnStar Rewards Pre-Owned Activation Incentive Program. It allows active participants in the program to submit claims when they activate OnStar on qualifying pre-owned GM vehicles. The app also enables users to check the status of their most recent claims and view their earnPOWER award point balance.

This app is not intended for use by consumers, and it does not contain any advertising. The primary function of the app is to allow non-GM dealership personnel to file claims, and it is strictly for individuals employed at non-GM vehicle retail locations. GM dealership employees can search for the "OnStar EarnPower" app for their program.

OnStar Rewards provides a convenient, mobile version of the OnStar Dealer Rewards website that allows users to help customers sign up for OnStar, file claims, monitor their rewards activity and progress, check out sales aids and useful handouts, and reward themselves. However, it is important to note that users need to have (or sign up for) an OnStar Dealer Rewards account to use this app.
