Check the connectors to the rear sensors, all 5 that are in my family are 06's and several have had a corroded connector to a rear sensor, or the rear wiring breaks. First get the codes pulled so you know what corner to work at.
Just a data point:
My wires to the rear were fine, but one of the sensors failed coincidentally with a deluge rain while the Jeep was parked on the street. I got in and tried to drive away during the deluge, and had the lights coming on within 30 feet.
Failure was intermittent over the next 2 weeks until I figured out where the problem was.
Replaced both rear sensors and test driving between them being replaced.
First sensor fixed it, replaced other side just in case.
10 minute plug-n-play repair per side.
