Dealerships installed alarms in millions of vehicles—and left them in even if the buyer didn’t want them. Now researchers warn they can be hacked to unlock, track, and disable cars.

FTA:

a model of aftermarket car alarm known as the KARR Security System, installed in more than 2 million vehicles across the US by their estimate

The KARR alarm devices are typically installed by car dealers, not manufacturers or owners, and used as a measure to prevent auto theft from dealer lots. Yet when the cars are sold, the alarms typically aren't removed, even if the buyer declines to pay for it as an additional feature.

you can check if your car has the device by looking for a KARR sticker on your car's driver-side window—or in some cases a sticker reading, “SWDS” for SouthWest Dealer Services, a subsidiary of Acrisure Protection Group—as well as a small button with a blinking light attached to the underside of your car's dashboard.

I'm going to guess that these are independent used car dealers, not branded dealers selling new cars.
