2007 Cadillac Dts with leveling rear struts have a serious issue in wiring to the rear suspension. Those operating in heavy road salt environment are experiencing wiring failures in quick disconnect terminals. Where wires are inserted into connector pins scop up salt against unprotected copper wire. This results in complete disconnection due to chronic corrosion. Thus the computer displays a trouble message in the main instrument cluster "service suspension." This wiring disconnect/open disables the air ride feature in the rear struts. The wiring involved resides under the floor pan and is unprotected from the elements. These wire failures can result in steering/handling difficulties due to rear seat and trunk heavy loads. Fix would be to require potting compound in all gallys where wires enter male pins and female receiver connections. Potting compound would create a waterproof exclusion to keep out the damaging elements. My vehicle was supposed to be a GM certified pre-owned car that originated in the boston mass area.
