The transfer case in your Jeep is responsible for sending power to all four wheels when you're in four-wheel drive mode. In some 2005-2010 Grand Cherokees and 2006-2010 Commanders, the transfer case's electrical system can fail, causing it to shift into neutral.
Risk if Unfixed
If this happens, your vehicle could roll away unexpectedly, which could lead to a crash or injury if you're not prepared.
Free Fix
Your Chrysler dealer will update the transfer case's software for free, which should prevent this issue from happening. You should schedule the repair as soon as you get the recall notice.

If there is a leak, they'll fix the problem and install a new seal and shield to keep the water out. This repair is free, and you should schedule it as soon as you get the recall notice.
