As the parking brake lever travel increases, the holding force may decrease to a point where the vehicle is no longer safely secured in all parking situations, allowing the vehicle to unexpectedly move when parked on a slope, increasing the risk of a crash.

In these vehicles, the lock nut that secures the parking brake cable to the parking brake lever may loosen over time, resulting in increased parking brake lever travel before the parking brake engages.

What to do: Book this in with a dealer now. It affects a safety system.
