P0300 random misfire detected

So approx. a month ago I kept throwing this code, I took it in, they swapped out the PCM, and then I threw the code again tonight. Any ideas?

So far they have changed the spark plugs, replaced the crank position sensor, done the tsb,checked the coil packs, and replaced the PCM. Today they're running a compression test and going from there

Let me get this escalated to the customer service manager for your area, onequickstang. PM me with your VIN, dealer, mileage, full name, and best daytime number.

I bought a 2015 mustang GT on December 26th and 2 weeks later, check engine light with P0300 came up. They tried to update the pcm but fried it. It was in the shop for 7 days until they got a replacement in and gave it back to me and said I am good to go. So after having it for 3 weeks... I got to drive it for 2 weeks. Well, the check engine light is back with the same code. This is ridiculous. I bought a brand new car to be trouble free. Negative. Maybe I shouldn't have bought another ford. Ridiculous!! So upset. Now I am going to have to take off work so I can get my brand new car fixed?!? I am so over this car already, I am ready to get rid of it. Anybody had any luck to just get a replacement and let the dealership deal with the problem? Any help is appreciated. Thanks in advanced everybody.

most service centers that I have seen have pretty long hours and should at this point give you something to drive while your car is being worked on. Have the dealership come and get it, tell them you don't want to drive it in this condition. Have them bring you a loaner. Also maybe you did get a weird one. did you look at the camaro before buying the stang?

I believe that their is a recall on this matter thru Ford.

Took in my car to the dealership this past Saturday for a different PCM code related issue and the service writer notified me of another recall being announced by Ford to update the PCM. They called it a drive ability PCM update.

He stated that the recall and software update is fairly new
