I have an update on my power steering unit error:
While I had not had a P.S. problem recently, I did start getting a "Service Suspension System" alert nearly every day. The error would resolve itself after a while. Took it to the dealer today, they found the front connector to the power steering unit was not pushed in all the way (not fully seated). There was a piece of plastic from the latch inside the connection, preventing it from going in all the way. Since fixing this, I've experienced no more errors. The mechanic mentioned much of the ECM communication goes through the P.S. unit and was likely the cause of the suspension errors (which were caused by an intermittent lack of communication).
Hope this helps someone with a similar issue.
