General Motors agreed to a $12.75 million settlement to resolve claims it unlawfully sold driver data in California.
The fine represents the largest penalty issued to date under the state's new data privacy law.
Legal filings alleged GM sold vehicle location and driving data to brokers including LexisNexis Risk Solutions and Verisk Analytics starting in 2020.
The settlement prohibits GM from selling driving data to third-party brokers for five years.
This agreement remains subject to court approval.
The case highlights growing regulatory scrutiny over how automakers monetize data generated by modern vehicles.
