2019 FORD MUSTANG Complaints

Took car into dealership because it was running rough at start up and check engine light came on. They told us today that coolant leaked into cylinder requiring head gasket repair and pissible engine replacement. The car has less than 40,000 miles, has been gently driven, with full service records from the dealership and the extended warranty just ended in July 2024. Reading online forums, this is a very common issue due to design flaw of the Ford Ecoboost engine. What recourse do we have?

My 2019 Ford Mustang Shelby GT350 was driving fine until all of a sudden I got a check engine light on the dash. The vehicle was not as responsive as usual and was shaking a little bit at idle. I shut the car off and then had it towed to the Ford dealership for further analysis. After inspection at a dealership it was identified, that my engine had failed. Cylinder 8 would not hold compression and had cracked the engine block. This failure can cause complete engine failure and can be a risk to the driver, passengers and anyone else in traffic.

Began over last month with difficulty or rough engine start in mornings Then engine overheated once and continues to lose coolant without visible sign of any leakage. Scan error codes P0300, P 0303, P 0304. Now with excessive steam/smoke out tail pipe when it’s started. Took to mechanic where they verified engine coolant is in atleast, cylinder #3. My safety and that of others is the engine can fail or completely break or explode while driving, causing failure to be able to control vehicle, possibly resulting in a crash or even death.

When the car is going 70+ MPH the doors will unlatch and open if they are not held shut. This was a recall on earlier models but not the 2019.
