When I start my car I see an error message on the dash that says "service active suspension". It does not pop up every start. Typically on a cold start after sitting a few days. It goes away after a few seconds. I have also noticed that many times, even of do not see the message, the car rides like the sport mode is activated (rough). (the dash does not show sport mode. If I turn the car off and back on it reds fine. Any suggestions or experience with this error?
