NHTSA Complaint #11465078 — 2016 FORD MUSTANG

What component or system failed or malfunctioned, and is it available for inspection upon request? -The engine on my 2016 Ford Mustang EcoBoost is malfunctioning. My vehicle's RPM drop extremely low then rev high, then the car almosts cut off when I drive at low speeds, park, or stop at lights/stop signs. How was your safety or the safety of others put at risk? -I stopped driving my car any further than 10-15 mile distances because I was afraid the car may cut off while I'm driving down the road in traffic. Has the problem been reproduced or confirmed by a dealer or independent service center? -I took my car to 3 different Ford dealerships, in Mississippi, North Carolina and Maryland. The first could not replicate the issue or find any issues, the second dealer whom I paid approximately $700 for repairs had my car for 3 weeks because they couldn't find the issue, so they replaced my spark plugs and an ignition coil and said it should be good. The third Ford dealership didn't diagnose it truly they just said it was leaking coolant so it had to be an internal coolant leak that has damaged my engine (causing a misfire), based on a Ford TSB that has apparently been out for a long time. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -It was inspected by 3 different Ford dealerships. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? -The first time I had this symptom was in the spring of 2021, but it was a one time thing and it went away. The next time I noticed the issue was around July of 2021 which is when I took it to the Ford dealership near me in Mississippi. The first time the check engine light came on was in April of 2022 when I arrived in Maryland after I took it to the repair shop in North Carolina. Note: I was in the process of moving from Mississippi to the DC area, otherwise I wouldn't have even driven it that far.
