Vehicle Data Recording and Privacy

This GM vehicle has a number of sophisticated computers that record information about the vehicle’s performance and how it is driven.

For example, the vehicle uses computer modules to monitor and control engine and transmission performance, to monitor the conditions for airbag deployment and deploy airbags in a crash, and, if so equipped, to provide antilock braking to help the driver control the vehicle. These modules may store data to help your dealer technician service the vehicle. Some modules may also store data about how you operate the vehicle, such as rate of fuel consumption or average speed.

These modules may also retain the owner’s personal preferences, such as radio presets, seat positions, and temperature settings.
