You may transfer your OnStar service plan if:
- You have an active, customer-paid OnStar service plan and account
- The primary driver does not change
- The new vehicle is equipped with OnStar hardware
If you still own the vehicle listed on your service plan, the plan cannot be switched to a different driver. Any service plan included with your vehicle purchase remains with the vehicle if it is sold or traded in with an active OnStar trial.
If you sell or trade in your vehicle, return a leased vehicle, or your vehicle is totaled because of collision damage, please call 1.888.4ONSTAR (1.888.466.7827) with your OnStar account number or Vehicle Identification Number (VIN). They will update your account status or transfer your service. You'll also need the date the vehicle was sold, traded or totaled. If you’re not eligible to transfer your service plan, a refund, if applicable, will be given for the remaining service plan time you purchased.
