NHTSA Complaint #11594168 — 2019 FORD MUSTANG

I had a solid check engine light 2 days ago and called my local Ford dealership and made an appointment for the next morning. I had not experienced any problems that I really noticed with the performance of the car, maybe some rough shifting. I waited at the dealership while the assessment was done and they said they would have to keep it overnight to do a head gasket test. They called this morning and said that I could come get the car if i needed it but I would need to keep a check on the coolant. I decided to leave the car at the dealership. After the call, I researched the web for similar issues that this particular mustang might have and I started to worry after the info I found and the similar comments on the 2019 mustang owners on this website.
