FeganScott is launching an investigation into General Motors and its OnStar division for allegedly using vehicles’ internet-connected system to collect data on driving behavior—like sharp accelerations or hard braking—and sell it to data broker LexisNexis Risk Solutions Inc. without drivers’ knowledge or permission. In turn, LexisNexis Risk Solutions sells the driver data to insurance companies, which use it to set rates, media sources report.

Some car owners had their insurance canceled or saw steep rate increases after their insurance companies used the driving-behavior data. Investigations revealed that GM collected and sold extensive records of their driving behavior, including details like trip length and driving characteristics, all recorded in the car’s OnStar system.

If you drive a vehicle equipped with OnStar, do not agree to have your data collected, and have seen your insurance rates increase, you may have legal options.
