What's wrong, in plain English
The wiring that controls the rear parking brake on these vehicles can become damaged or corroded over time. If this happens, the parking brake may switch on by itself while you are driving, even though you didn't touch it. The same wiring problem can also cause the parking brake to stop working altogether once the vehicle is parked, so it may not hold the vehicle in place. Either way, the parking brake isn't functioning the way it's supposed to.
