Taking a few guys to the airport yesterday, the car was acting strange, down on power and the MDS wasn't working. It had felt a bit doggy for a few days however this was definitely different. Got it home, shut it off, fired it up a few hours later and was greeted with a CEL. Plugged into AutoEnginuity which greeted me with two codes:
P0520 - Oil pressure sensor out of range
P2098 - Post cat fuel trim too lean on bank two
A quick Google yielded TSB 18-034-14 which listed a defective oil pressure sensor on cars manufactured before March, 2014 (mine was built November, 2013) that would result in this issue.
Dropped the car off at around 10:30AM, they gave me a loaner, and I was back in my car by around 2:30PM with the updated oil pressure sensor installed and the car behaving like it should.
All-in-all a pretty painless experience.
I'm thinking that since that pressure sensor controls the MDS operation, that this was causing some sporadic operation which in turn resulted in the lean code, as that's gone and has not come back.
Note: gas mileage with the MDS disabled (it didn't work all the way to Toronto and back) is significantly worse than with it operating. I burned 1/2 a tank going there and back
