Mine flared up just this afternoon.
Started with a prompt for the code. (36421 for the '08 Sport) accepted it, but the /!\ lit up once under way
Nothing in the ECU menu, but had the following dashboard codes:
Code#. A. M.
01. O. X
08. O. X
I'd stopped for gas,then drove 1/2 block & parked a minute then attempted to re-start when it prompted me for the code.
Tis the season.
