OnStar® Voice Fallback Number Update Some customers may have received a letter from OnStar® stating that "We recently tried to provide a software update to the OnStar® hardware in your vehicle. However, your system could not be updated remotely. As a result, some of your OnStar® system functions may not be working as expected." The customer is further instructed in this letter to "Please contact your dealer  or any dealer near you  as soon as possible to schedule an appointment for this no-cost software update. Your dealer will reprogram your OnStar® module with an update. This is for vehicles that have previously received the Canada upgrade as described in Service Bulletin #15-08-44-001F."
