GMC admits it’s paywalling important diagnostics data
So much for owning your ride. GMC now admits it’s locking critical diagnostics data unless you pay up. Independent mechanics and DIY owners? Left in the dark. It’s less “professional grade” and more “pay to play.”
GMC’s diagnostics paywall hits independent mechanics
In a new plan released to customers, GMC lays it out: basic OnStar diagnostics come free for a few years. But after that? You’ll need to pony up for a “Connected Vehicle Plan” or “OnStar Premium” just to keep accessing the same data your vehicle’s already generating with your phone.
“Diagnostics through the vehicle mobile app and remote key fob services require a Connected Vehicle Plan or OnStar Premium Plan,” GMC says in a document shared with vehicle owners.
That’s not just phone integration. That’s stuff like tire pressure and oil life. Features mechanics rely on. Features DIYers used to get for free. And now? They’re tucked behind a paywall.
As I previously wrote, Chrysler pulled the same stunt with its Secure Vehicle Gateway. Even certified mechanics need to register with AutoAuth, pay $50 a year, and jump through hoops just to read advanced codes. Ford’s considering a similar move. And GM? They’re racing ahead.
This diagnostics paywall isn’t about security
Don’t buy the cybersecurity excuse. GMC isn’t doing this to protect you. It’s about padding profit margins.
As I previously wrote, GM told shareholders their future vehicles would be “technology platforms” designed to squeeze drivers dry through subscription fees. “Utilify,” their in-car app store, is a money funnel. Third-party apps pay GM for access. And now it seems basic diagnostic info is part of that gold rush.
Seems dire, but we’re still far from the endgame of the subscription fee plan. Stellantis is charging Dodge owners hundreds just to unlock full horsepower in Charger EVs they already bought.
Let’s be real—GMC isn’t protecting you. They’re protecting their revenue stream. And unless regulators step in, more automakers will follow suit. If your dashboard lights up tomorrow, good luck fixing it without a login.
