Engine Failure problems of the 2016 Ford F-150

2016 Ford f150 with 55,000 miles. Started driving vehicle, engine rpm dropped, engine missing and shaking. No throttle response. Vehicle just idled horribly. Dash had large wrench symbol and an "accutrac service needed" warning. I turned off ignition, restarted vehicle. Same results. I did this 4-5 more times. Last time vehicle idled okay and accelerated. Drove the vehicle 60 miles home with no ther issues. Checked with an obd-ii diagnostics and gave 2 codes: p2111 throttle control system-stuck open and p2112 throttle actuator control system-stuck closed. Now, now warning light or any indication of problem on dash. No warning lamps prior to problem. Safety was at risk because without warning, pulling out into heavy traffic and losing the ability to accelerate with traffic could cause a serious accident. Looking this problem up in an online Ford f150 forum indicates this is a fairly common problem. Why has there been no recall for this potentially deadly engine failure circumstance?.

While driving about 20 mph through a residential neighborhood, vehicle lurched and jerked with a large thud. Thud was engine failing due to no oil pressure - oil not getting to engine. Limped home, car not able to go more than 30 mph to drive to dealership. Not shifting between gears. Had we been on highway, much bigger issue could have occurred - we were able to stop safely as we were in our own neighborhood. Ford is replacing engine but ryan holcomb (service manager at walker Ford, clearwater florida) has told us this is the fourth 2016 f150 that has come back to their dealership for a full engine replacement, and decision was made to continue selling because percentage of affected vehicles is a gamble. We bought truck 1/2/17, engine failure occurred 1/26/17 at odometer reading of 844 miles. Dealership in possession of truck since 1/27/17.
