Had to pull over, turn off the car and restarted, the error message remained advising me that "a full system check is recommended to be done soon".
Bringing it in this coming Tuesday. I will post what comes of it.

Your error was not the transmission control system, correct?

I ask because lots of us have had a similar experience with the transmission control system error (resulting in transmission replacement in my case. I hope your error is easily fixed.

Thanks for the reply -
The error message says Engine Control System.

Update
Went in to dealer today. They did the TCU update.
Checked the DTC and ended up replacing a connector on the throttle body. Found a loose wire.
On the way home I did not notice any rough shifting due to the update.
How old is your SC? How many miles? Wondering if the loose wire was there the whole time, or if the connector worked its way loose over time.

We got out SC Limited anout 5 months ago.
We have about 3000 miles on it.
This is the only problem we have had with it.
Unfortunately, it is similar to what some others have experienced.
There are some similar complaints on the NHTSA site.
Hope the problem is solved. Time will tell.
