I think the parking brake on my wife’s 2018 CX-5 got applied accidentally. Can this happen while the vehicle is off? Now the orange light on the switch is flashing, the electric parking brake warning light on the dash is on, and the brake system warning light on the dash is flashing.

I tried pressing the brake down and lifting the parking brake switch but that doesn’t change anything.

Any ideas before I take this into the shop? Thanks in advance

    Try putting it into maintenance mode, turn the car off and on, then disengage maintenance mode.

    it could very well be a weak battery. new cars have so many electronics and sensors with really low voltage needs, so a weak battery won’t be able to correctly supply voltage to everything consistently and it could cause major disruption throughout the car. have the battery and alternator load tested at like an auto parts store or something. if all is well it could be an issue with the switch, the control unit, or even the rear calipers with the motors that physically engage the parking brake. but with the slow cranks you mentioned a battery is most likely. i’ve seen cars with dying/old/worn out batteries cause some really strange issues or throw the most oddball codes that make no sense in relation to the data being read or the actual behavior of the car. i think i have seen some recalls/tsbs related to mazda and the rear calipers failing so look into that to see if it applies to your car.

      Thanks for the advice. I didn’t even bother testing the battery knowing it was over 5 years old and never replaced. Put a new one in and everything seems to be working fine…for now. Fingers crossed.
