The California Privacy Protection Agency (CPPA) is probing the data privacy practices of connected vehicle manufacturers and their technologies as part of its first enforcement review.

The review is “critical because these vehicles often automatically gather consumers’ locations, personal preferences, and details about their daily lives,” the CPPA said in a press release Monday.

“[Modern vehicles are] able to collect a wealth of information via built-in apps, sensors, and cameras, which can monitor people both inside and near the vehicle,” said CPPA Executive Director Ashkan Soltani in the release. “Our enforcement division is making inquiries into the connected vehicle space to understand how these companies are complying with California law when they collect and use consumers’ data.”
