I have a 2006 STS 1SG with Magnetic Ride (Delphi MagneRide suspension control system) shocks. In my following of the forum I have not seen the answer to my question, which is, do the Magnetic Ride Shocks wear out or go bad? If they do go bad, is there a reason or timeline? If they need replacing off warranty, any idea of the cost of each? Do they have to be done in pairs like regular struts or shocks?
Thank you for your answers in advance.
