Buick Car App — Lock, Unlock, Fuel & Location from Your Phone
CarConnect works with Buick vehicles: lock and unlock from anywhere, see live location and fuel level, and keep documents and service history in one place — all from your phone, with no wiring or extra hardware. It requires an active connected-services account (OnStar (myBuick app)) and a supported model year.
Buick models CarConnect works with
9 Buick models, generally from model year 2010 onward. The free compatibility check names exactly what your model and year supports, in a few seconds, with no account and no card.









Your Buick, in your pocket
Lock & unlock
Lock or unlock from anywhere — no key-fob range limit — and see the real lock state, not a guess.
Live location
See where the car is parked (or headed) on a live map, using the vehicle's built-in GPS.
Fuel & status
Fuel level or EV charge, odometer and vehicle status at a glance before you leave the house.
Documents vault
Insurance, registration and service records in one place, attached to the right car.
Service reminders
Maintenance history and reminders so nothing on the schedule slips.
Feature availability varies by Buick model, year and connected-services plan — the in-app compatibility check shows exactly what your car supports before you subscribe.
Connect your Buick in three steps
Check your Buick
Pick your Buick model and year in the free compatibility check — you'll know in seconds whether your car qualifies.
Activate connected services
Make sure your OnStar (myBuick app) account is active. Most recent Buick vehicles sold in the USA already include one — your dealer can confirm.
Link and go
Sign in to your connected-services account inside CarConnect. No wiring, no hardware — your Buick appears in the app in minutes.
Buick owners ask
Does CarConnect work with Buick vehicles?
Yes — CarConnect works with Buick vehicles that have an active connected-services account (OnStar (myBuick app)). Once your account is linked, you can lock and unlock, check location and status, and manage your car from the CarConnect app.
Which Buick model years are supported?
Coverage generally starts around model year 2010 and depends on the model and region — support comes from the vehicle's built-in connectivity, not from any hardware we add. The fastest way to check is the in-app compatibility check: pick your Buick model and year and you'll get an instant answer.
What do I need before connecting my Buick?
An active OnStar (myBuick app) account. Most Buick vehicles sold in the USA in recent years already include one — your dealer can confirm or activate it. No wiring, dongle or extra hardware is needed.
Does CarConnect replace the official Buick app?
No. CarConnect is an independent companion app that works alongside the manufacturer's own app. Many drivers prefer it for its clean interface, multi-car garage (even across different makes), and extras like a documents vault and service reminders.
What if my Buick isn't supported?
If the compatibility check can't match your model, it's usually an inactive connected-services account or an older model year. Reach out at support@loopmobile.io and we'll check your exact configuration — every plan is covered by a 15-day money-back guarantee, so trying CarConnect is risk-free.
