How long ago did you buy it? Surprised you haven’t called the dealer and have it towed there on a flatbed.

Just for grins, if you think the parking brake diagnosis is simple, you would not believe how many sensors are involved. Check this out:

If you bother to look, you'll see there are literally scores of sensors, microswitches, electric motors, computers and canbus messages that could cause a problem. Makes one wish for a manually activated parking brake.

Holy crap! Yeah I'd rather have a cable setup that rusts if you don't use it!

Mine got stuck in Brake Service Mode when I was swapping rear rotors a while back…had to get a buddy with a serious scan tool to come figure it out. It had a code for a temp sensor on the rear caliper being out of whack. FYI there is no temp sensor on the rear caliper.
