Terrain Mgmt System Fault

2017 with 66k miles...wrench light comes on while accelerating onto 95 after a fill up. Says check manual and then “terrain management system fault” No limp mode or anything else. Haven’t found much of anything about this..convenient timing too as I’m out of town for Memorial Day..

any ideas?

Found this via google, not sure if at all helpful....

TERRAIN MANAGEMENT SYSTEM FAULT: Cycling the key may clear the fault. If key cycling does not work, have the system serviced by an authorized dealer.

MODE CHANGE NOT ACCEPTED, RETRY: A mode change cannot be made at the time of driver request. Try the mode change again.


Could always disconnect the battery for 15 min and see if it goes away when everything boots back up.

Looks like only negative would be lack of availability of certain drive modes, and/or hill start assist.
