GM's Super Cruise: Paid Off in Full, Still Billed Monthly for the Feature

Owners can pay off a GM vehicle in full and still lose Super Cruise access three years later without an active OnStar subscription — here's what that costs.
A buyer can pay off a car in full and still lose access to the installed Super Cruise system after three years. To keep the feature working, GM requires an active OnStar plan priced at $39.99 a month. Digital subscriptions are becoming a real line item in the cost of owning a Chevrolet, GMC, Buick, or Cadillac — not just a footnote.
Business Insider reports that GM’s software services bring in about 70 cents of gross profit on every dollar of revenue. In the second quarter of 2026, OnStar generated roughly $800 million, more than 20% above last year’s result. By year’s end, the company expects to approach 13 million OnStar users.
The comparison to “four cents on a car sale” needs a caveat. It isn’t about GM’s exact profit per vehicle, but the typical automotive margin range of 4–10%. The subscription figures also use gross margin, while GM reported an adjusted EBIT margin of 8.6% for its North American business in the second quarter. These numbers sit at different levels of financial accounting, so dividing one by the other directly isn’t accurate.
Super Cruise shows why automakers are drawn to this model. GM expects more than 850,000 active subscriptions by the end of 2026. Once the three-year included period ends, 30–40% of eligible owners keep paying for the plan. The system itself only works on compatible roads and doesn’t make the car autonomous — the driver still has to watch the road and be ready to take over.
For anyone buying a used car, the condition of the body and the service history aren’t the only things that matter. It’s worth checking which digital services are included, when the free period ends, and how much renewal will cost. The remainder of the original three-year Super Cruise access carries over to the next owner, but once it runs out, features that depend on map updates, precise positioning, and OnStar support stop working without a matching plan.
A subscription shouldn’t automatically lower a car’s value if the owner understands the cost upfront and can opt out of the service. The problem comes when the price of continued access isn’t disclosed at purchase, or when a feature the buyer assumed was part of the package simply stops working without payment.
