NHTSA Complaint #11672603 — 2019 FORD MUSTANG

My vehicle recently had a head gasket leak due to a faulty engine block design. I noticed one day the coolant was lower than it should be but nothing concerning, over a month or so it got progressively lower & the car would also sputter/misfire on startups from time to time. This is due to coolant slipping through the gasket & getting into the cylinder & oil which can lead to catastrophic engine failure or worse. Eventually I got a check engine light & was told it was a misfire after running a diagnostic on the vehicles OBD2. I researched what the issue could be &it became more & more apparent that it was a head gasket issue. The oil was contaminated & coolant was getting very low. Apparently it’s a big issue since Ford is now facing a class action over the defect. The vehicle also has some issues with the transmission, for example ill start the car up on a cold California morning 50°F & let it warm up before driving & when I go into reverse after the car will jolt hard as if you were backing up & hitting something like a wall, even in the afternoon when you start it from a cold start & go into reverse it will do it. Not sure why but it’s concerning to say the least. The transmission also feels confused when shifting, when I’m in 4th about to push fit it will get confused & revs will drop slightly before going up again to up shift, also when downshifting due to braking the shifts can feel a bit hard, especially when needing to stopping fast. The engine & transmission are the most importantly parts of a vehicle & without them working properly is something no one should have to face.
