Dealer just informed me the root cause of these DTC codes for my instance is a bad purge valve.
So they ordered one, needs a few days.
It would not throw these engine codes in normal easy driving. When reset it would stay off for a while. But in Sport+ mode it would throw codes pretty...
Only happens in parking lot scenario; low speed, tight turns. Maybe differential, bearings? 2015 v6 auto 69k mi. new tires. It rumbles enough to rattle the dashboard up front and I can really feel it and hear it.
Any ideas?
