I have a 2000 Cadillac sts I have had the car for about 2 years and have quite a bit of work into it, It just recently started saying "service suspension sys" It will go away and come back on. It first came on a few days ago and then went away and then just today it came back on. I just took to the shop about 2 to 3 weeks ago for a a new alternator I don't if that would have anything to do with it. It also has been making a weird clicking noise when I turn the wheel or hit a bump. I have looked online and found a few different answers so I am just wondering if anybody has had this happen and knows what it is.
