Vauxhall OnStar

What is Vauxhall OnStar?

Vauxhall OnStar is your in-car ‘concierge service’ providing a direct link between your car and Vauxhall by using GPS technology and 4g Wi-Fi. OnStar can help with technical queries, automatically alert emergency services in the event of a crash and can even help trace your car if it is stolen! Vauxhall provides a year’s free subscription to OnStar on selected new cars, after which annual subscription costs just £79, although the wi-fi hotspot requires a 4G signal to work and will cost extra.

The diagnostic systems monitor things like your tyre pressures and engine oil level, which can be viewed using a smartphone app or e-mailed to you and dashboard warning lights can be diagnosed by an OnStar advisor, who can book your car in for service or repair if necessary. The OnStar smartphone app can remotely lock and unlock the car’s doors and pinpoint its location on a map, making forgetting where you’ve parked or searching for it in a crowded car park a thing of the past. The app also has a timer function that can be set to remind you when your parking ticket is about to expire!
