When starting the car the parking brake light on the dash and the light on the parking brake switch will flash, as if the parking brake cannot be turned off. This is an intermittent issue that had happened to me twice in the last month. Dealer says they don't see any codes in the computer and their best guess was that the car's battery may be running low. They've replace the battery so we'll see if that resolves the issue. Hopefully the brake will not engage at random as others have reported.
