NHTSA Complaint #11561652 — 2018 FORD ECOSPORT

My car first came on with a check engine light at 53,000 miles. Got it coded that the car prompted and it was reading P015B which indicates bank 1 sensor 1 of O2 sensors experiencing a lean to rich response issue. I scheduled an appointment with a mechanic to have it looked at. It drove fine for 24 hours. The next day my car started to run rough and the oil light came on as well with an error message reporting low oil pressure. I recently got an oil change done a week prior. I did take the car back to where I got the oil change. The company did not find any issues with the oil change but proceeded to change it anyway again. They advised me at that point to not drive the car till diagnosed at a dealership. At this point I have had the car towed to a local dealership. I am told over the phone that it may be due to a know issue with my car of a bad oil pump and could risk blowing the engine. I am awaiting further diagnosis after the holidays.
