"Sorry to hear that Jackie. I'm certainly not an expert on newer Jeeps... I'm assuming it's an automatic? If so, have you checked the fluid level, color, smell, etc? If it's real black or smells burned, it needs to be flushed out. Have you noticed any change in the way it shifts gears? Have you had it serviced routinely (as in power flushing the fluid, dropping/cleaning the pan and replacing the filter)?"
That's what most of the stuff I found in google search suggested to do. I honestly don't know if/when it was done. Mine is a 2008. I'm the only owner. 82,000 miles. I haven't done anything but oils changes, brake service and axle bearing replacement.
