2020 Ford Mustang

On 03.29.25 (Saturday) the car started rough and the check engine light came on. I took it to the mechanic 03.31.25 (Sunday) and they inspected the car and told me that it is either the head gasket or the engine block is cracked because there is coolant intrusion into the cylinders. They asked me to call FORD customer service and ask if there was any way to cover it under warranty as the car only has 64K miles. I was told no, the warranty was 5yrs or 60K whichever came first and the 5 years was October of 2024. They suggested I file a report with the NHTSA. The vehicle right now is at the mechanic as I try to decide what I would like to do with it. If the engine failed when driving, I don't know what would have happened. There were no other symptoms to the problem prior to the failure. In fact, weeks earlier I had it inspected to see if any maintenance was needed and it got a clean bill of health.

After driving for 2 blocks, my car would not drive when hitting the gas pedal, the engine only reved. Unable to move the car in any gear, pedestrians helped push my car out of the middle of the road. Towed the car to a Ford dealership because the Ford app on my phone said "shift solenoid stuck in off position". Upon diagnosis the dealership said yes the solenoid is stuck in the off position but now the gears are slipping and you need a brand new transmission. This is the 10r80 automatic transmission that has had problems like this nationwide. I don't understand how this has not been recalled yet. With 63,000 miles a transmission should not be failing. There have been hundreds of documented cases of this specific transmission failing for countless reasons involving internal components.
