Some 2015-2021 Ford and Lincoln vehicles may exhibit an illuminated MIL with diagnostic trouble codes (DTCs) P0011, P0012, P0014, P0015, P0016, P0017, P0018, P0019, P0021, P0022, P0024 and/or P0025. Pinpoint test HK in the Powertrain Control and Emissions Diagnosis (PC/ED) or in Section 303-14 of the Workshop Manual (WSM) has been updated to address this concern.

Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Some 2015-2020 Ford and Lincoln vehicles may exhibit an illuminated MIL with diagnostic trouble codes (DTCs) P0011, P0012, P0014, P0015, P0016, P0017, P0018, P0019, P0021, P0022, P0024 and/or P0025. This may be due to small debris causing the VCT solenoid to stick. Before attempting any component diagnosis or replacement of the VCT solenoid, refer to Powertrain Control and Emissions Diagnosis (PC/ED) pinpoint test HK11 to cycle the affected VCT solenoid 10 times to attempt to clear the debris. For claiming, use causal part 6M280 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
full bulletin at NHTSA ↗On vehicles equipped with an automatic transmission it is imperative that the converter pilot hub be greased with Motorcraft Multi-Purpose Grease Spray XL-5-A even if grease was not applied from the factory. Also verify that the engine/transmission alignment dowel pins are present as well as the engine crankshaft dowel pin, if equipped, when installing the transmission. Failure to adequately lubricate the converter hub greatly increases the likelihood of the flexplate cracking in the future. Missing dowels may cause a misalignment issue also resulting in a premature failure. Refer to Workshop Manual (WSM), Section 307-01.

Since around 20,000 miles, my 2018 Ford Fiesta SE has had a grinding noise after shifting at certain gears. I got the car serviced at that time. Now I'm at 70,000 miles and the noise has persisted, and has gotten worse. My transmission slipped at 0mph when I was accelerating, almost causing me to lose control of my car.
The car was driving at 68 MPH and approximately 2500 RPM started to loose speed down slight hill and rpms increased to 5,500 RPM. Let off the accelerator 3 seconds rpms decreased reapplied accelerator and operated properly.
Car shudders upon acceleration from standstill. Loses power severely going uphill. Engine/transmission shakes shudders engine races and quickly accelerates after loss of power then decreases again. When moving from stop car shudders makes a grinding noise and then slowly accelerates before decreasing RPM and then races again. *tr
