NHTSA Complaint #11438313 — 2013 FORD FOCUS

This car started to make loud engine noises which caused the car to shut off then it restarted on it's on I finally got it to parking lot when I cut it off it still was rattling and clacking like I was cranking it up on the left side of engine so I waited till about 30 minutes what ever it was it killed my battery then it started back up again but then through a check engine light on but when I got it checked it wouldn't read any codes so the display on board of the car read transmission shift in reverse but I wasn't in reverse so it was stuck in transmission mode and could not drive it I got it at a shop which they only would say a transmission, but they only wants to put a transmission in with out checking if it could be anything else like a electrical problem but he says no a transmission so now I'm only at 150k miles and this goes out without notice, I even asked about the transmission acuator but he says no the whole transmission, I just got the car like 3 months ago, and that is no good
