Just had oil changed, noticed engine light came on a day later (perhaps not related), had a few hesitation moments during acceleration (at around 25mph). Ran car a few trips, put in garage overnight. Next day engine light off and no hesitation. Had error codes checked and P0171 (Fuel Trim System Lean) came up. Thougths?

I had this issue and discovered it was a failing of failed pcv valve which is integrated into the valve cover

Literally having the same issues as each party stated above! It’s a 2019, 46,000 miles well taken care of! Maybe this should be a Recall fix because it’s quite dangerous to operate at this point!
