Same Issues on my 2013 GT (Maunual Tran.). 743 miles car stuttered light came on solid no flashing, pulled over turned off car light was off car acted fine. Sync health report showed no issues. Called dealer told to bring in if it did it again. 926 miles car stutters light came on (flashing) pulled over did not kill car, light went off after 30 seconds before i could start Sync. Health report said no issues, took to dealer had car 2 days was told it showed no codes and they could not replicate after driving.
Was told if it did it again to continue driving if it occured and bring back to service. Happened on first drive out after recieving car 1005 miles, did not pull over light flashed and then went out again after about 30 seconds. I did manage to get a video of light flashing, speed 35 mph, 2k on tach, 4th gear.
Each time it has happened it has been low speed.
