Chie Ferrelli loved her Subaru SUV, which she bought in 2020 because it made her feel safe. So when it was time for her husband, Marc, to purchase his own new car last summer, they returned to the Subaru dealer near their home in southeast Massachusetts. But there was a catch, one that made the couple mad: Marc's sedan wouldn't have access to the company's telematics system and the app that went along with it. No remote engine start in the freezing New England winter; no emergency assistance; no automated messages when the tire pressure was low or the oil needed changing. The worst part was that if the Ferrellis lived just a mile away, in Rhode Island, they would have the features. They bought the car. But thinking back, Marc says, if he had known about the issue before stepping into the dealership he "probably would have gone with Toyota."

Subaru disabled the telematics system and associated features on new cars registered in Massachusetts last year as part of a spat over a right-to-repair ballot measure approved, overwhelmingly, by the state's voters in 2020. The measure, which has been held up in the courts, required automakers to give car owners and independent mechanics more access to data about the car's internal systems.

But the "open data platform" envisioned by the law doesn't exist yet, and automakers have filed suit to prevent the initiative from taking effect. So first Subaru and then Kia turned off their telematics systems on their newest cars in Massachusetts, irking drivers like the Ferrellis. "This was not to comply with the law—compliance with the law at this time is impossible—but rather to avoid violating it," Dominick Infante, a spokesperson for Subaru, wrote in a statement. Kia did not respond to a request for comment.
