2019 Ford Mustang: engine stalls while driving

Filed Oct 21, 2026 · Engine · NJ

My 2019 ford mustang egoboost with only 59,000 miles has a cylinder three coolant intrusion. This is disappointing, as the only right way to fix this according to Ford, is to replace the whole engine. Nobody should expect to have to fix their entire engine. Now on cold starts coolant is leaking in to cylinder three, which is causing misfires and could potentially lead to a safety, risk. Ironically, there’s a lawsuit currently in place for this exact problem. This is a problem, sudden engine failure or stalling due to severe coolant intrusion introduces a dangerous loss of power while operating the vehicle at speed and could lead to a blown or locked up motor. Ford has kept this under wraps since the release of this generation of vehicle.

Have a 2019 Ford Mustang 2DR 2.3L Ecoboost with 59,500 miles which I took to the dealership with a code P0302 and P0304 present, cylinder misfire, observed coolant level low, performed borescope in cylinder 2 and 4, found coolant intrusion, recommend long block engine replacement which would have cost me $10,728.85. Concern is that the engine can stall suddenly and may cause an accident. Ford Motor Company knows about these kind of engine issues with Ecoboost engines and have not offer any reasonable solutions.

I am filing this complaint regarding a vehicle I purchased from Florida Fine Cars in Miami Gardens on [XXX}. The vehicle is a Ford Mustang GT with a Roush supercharger (VIN: [XXX] ). Immediately after purchase, the car exhibited serious performance and safety issues that were never disclosed by the dealer. Within hours of driving home, the vehicle showed severe power loss, hesitation during acceleration, and loud mechanical noises at highway speeds. These issues were not detectable during the brief, low-speed test drive the dealership provided. Additionally, by the next morning, the car emitted a strong plastic or chemical odor under the hood, which intensified in the Florida heat — suggesting a possible engine, exhaust, or emissions-related fault. The dealer misrepresented the condition of the vehicle, repeatedly claiming it was “fully inspected” and “in excellent condition.” However, a certified Ford dealership technician later confirmed that the car “ran like garbage” and required immediate diagnostic attention. These defects are potentially safety-related, as they directly affect the engine’s performance, drivability, and emissions integrity. The vehicle could stall, lose power during acceleration, or emit toxic fumes. Florida Fine Cars has refused to take responsibility, despite clear evidence that the car was sold with undisclosed defects. Their actions constitute false advertising, misrepresentation, and a disregard for consumer safety. I urge the federal safety agency to record this complaint and investigate whether similar vehicles sold by Florida Fine Cars (or others with aftermarket superchargers) have unreported safety or emissions defects. This poses a serious risk to consumer safety and compliance with federal motor vehicle safety standards. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle was purchased new in 2019 and in 2022 my transmission started with harsh gear changes which resulted in a reprogram/relearn of the transmission. As of May 2025 my transmission is doing the same and has now caused my vehicle to stall while at a red light. In addition to this I have not seen any warning signs or check engine lights.

The car was purchased last november 2019, during the first month, I noticed that the icp was not properly working while using the GPS- it gives wrong direction even the settings were correctly set, like it was remotely controlled. Besides that my battery was discharged that I needed to jumpstart it and towed it because the 1st time jumpstarting didn't work. It happened 4x, brought it twice to ford dealer to check everything was okay. It even send me alarm thru ford app that it was put on "sleep mode" even it was parked and it is frequently used. Not only that, the both windows were opened when I got back from an hour errand. With regards to the seat belts, there's no warning that flashes on the dashboard when not in used while on the passenger side despite riding with someone. It is also loose after removing it, you need to pull it manually to return to the short length when not strapped. The engine stalls when shifted from reverse to drive, it needs about 5-10 secs to work.

Riding under normal driving conditions, car stalls from a v8 to a v2. No power at all, if you want to switch from normal, to any selectable driving modes from toggle switch or steering wheel, wont change. Turn of car, turn it back on and continued with same problem.
