If you own an older Chevy model or other vehicle made by General Motors and notice that OnStar® is no longer working, you’re likely wondering what happened. The bad news first: it’s no longer compatible with certain GM vehicles. The good news is that Carroll Chevrolet has a few tips to help.
OnStar and Connected Services
OnStar is designed to keep you connected anytime, anywhere. You have immediate access to emergency services whether you’re in an accident or your vehicle is stolen, even if you can’t ask for help yourself. You can also get roadside assistance, and OnStar advisors can even provide turn-by-turn directions when you need them.
Cancellation in Select Models
The OnStar and Connected Services feature is no longer compatible with select GM models. Vehicles from 2014 and earlier (and select 2015 models) are affected. This includes Chevy, Buick, Cadillac, and GMC vehicles, as well as retired brands, including Hummer, Pontiac, Oldsmobile, Saab, and Saturn.
Networks are No Longer Compatible
The cancellation is a result of changes in the service’s cellular network. The older GM models utilize Verizon’s 2G network to provide OnStar and Connected Services. However, with the shift to the 4G and 5G networks, these vehicles are no longer compatible.
Access Through the OnStar Guardian App
While you can no longer access OnStar services through your vehicle, you’ll still benefit from these services by utilizing the OnStar Guardian app. If you already have an OnStar Safety & Security, Essentials, or Premium plan, the app is already included. You’ll also see an automatic reduction in your monthly subscription’s cost to offset the cancellation of in-car services.
