P0171 fuel trim system lean.

Chevrolet Trax 2016  52000 miles
Check engine light is on and now the traction light is on. Car runs rough when stopped and it loses power when accelerating form a stop and going up hills. Code reads P0171 fuel trim system lean DTC severity 2-3. Any info on cause?

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!
