Always had service ride control message displayed since i bought the car. Just made the car ride stiff. I replaced the front struts with generic non road sensing ones. I replace the back with aftermarket air struts. Works great now! Do this repair yourself! Just rent the spring compressor from autozone for free. There is a detailed how to online with pics too.
The Service suspenion msg has been on since I bought it. I changed the rear shocks (after market) the sensor was not attached to the shock. I installed it on the lower support. Light was still on. Had them run the codes and the results were a slow data flow for the turn leveling system. I am guessing a corroded connection or a wire has been rubbed on something. They were going to charge me $80.00 an hour to trace down the problem with a OHM meter. Not! I found the wiring diagram and plan to trace it myself. Has anyone dealt with this issue? I dread crawling around under there with a bad back and neck injury.
