There is a simple fix for this problem. You can replace the plastic bushing and small plastic nipple with a much stronger 3/8 grade 8 bolt. All you need is a wrench and/or ratchet and a drill. Anyone can implement this fix.
You'll need the following...
A drill, a 3/8" 16 1 and 1/2 grade 8 bolt, a 3/8 drill bit, an aircraft (lock) nut, and two 3/8 washers.
Before beginning, place the Jeep in Park, apply the parking brake and chock the wheels.
IMPORTANT: The transmission may potentially change gear during the course of the install, so DO NOT rely on the Park gear to hold the vehicle in place!!
