Interior Brake Light Normal for GM

Order Reprints
KEYWORDS GM Mitchell 1

Owners of 2013-2018 GM passenger cars and trucks equipped with electronic park brake systems (EPB) may comment that the red park brake light on the instrument panel intermittently comes on.

This may be due to the vehicle automatically applying the EPB when the vehicle is not moving. This is normal and is done periodically (every 50 key cycles) to check the correct operation of the EPB system.
