Engine coolant leaked into the cylinders. Overheating. Coolant leaked into catalyst. ODB Error codes attached . Independent service center replaced short block, see attached invoice. Engine light on.
Head gasket blew, and car overheated immediately on the freeway, with no warning signs, and at only 43,000 miles when a failure like this should not occur. Had to find a place to pull over and be towed to avoid more engine damage. Both independent mechanic and Ford dealership has confirmed this. Official diagnosis is "Remove and replace cylinder head assembly and replace head gasket – coolant intrusion cylinder 1, P0316, P0301.” Apparently it's a known issue with this particular engine and has a pending lawsuit.
I took my car to ford and the guy working hit a curb in there own buisness and they had to replace my two tires and rims and I just don’t trust anything because it took them 2 months to fix it , happened like a year ago

Th cluster remains blank when this happens until the car is off for over an hour or disconnecting the negative battery (soft reset). While this is going on the vehicle isn't safe to drive. No speed, gear, emergency alerts, nothing is visible.
My 2019 Ford Mustang equipped with the 2.3L EcoBoost engine developed a check-engine light, rough startups, engine misfires/rough running, and some engine knocking. The vehicle had approximately 87,453 miles. I took the vehicle to an authorized Ford dealership for diagnosis. The dealer brought the engine to operating temperature, pressurized the cooling system to 21 PSI, removed the ignition coils and spark plugs, and inspected the cylinders with a borescope. The dealer documented coolant intrusion into cylinder #2 due to a failed cylinder head and recommended replacement of the complete long-block engine due to the extent of the damage. The dealer also documented diagnostic trouble codes P0300 and P0316 for misfires, along with P008A and P018C related to low-side fuel pressure. I am concerned that internal coolant intrusion causing misfires, rough operation and engine knocking could result in significant loss of engine power or engine failure while driving, creating a safety hazard, particularly at highway speeds or in traffic. Ford Customer Relations was notified but declined financial assistance because the vehicle is outside the factory warranty and stated that there is no applicable recall for my vehicle. The vehicle has not been repaired and is available for inspection. The Ford dealership's written diagnostic report and photographs of the cylinder inspection are available.

Engine Failure where a replacement engine is required just after a few months of purchasing the vehicle.
Coolant intrusion. This particular motor has caused NUMEROUS issues with 2019 & older Ford models, specifically with the 2.3L Ecoboost engines. The Ford Motor Company should recall & replace the engines of all models affected, mine included. I spent $2200 for a new timing system, tow fees, was broke down on the side of the road when my engine overheated. I bought this car brand new. Financed $27k & owe $3900 right now. Devastated & livid describes how I feel at the present. Coolant intrusion causing hydrolock is a KNOWN issue by Ford, and they should make things right with the owners of the vehicles affected. A new motor will cost $6500. That should NOT be a cost that the customer has to pay.

Rebuilt transmissions are bad. Two in the last four weeks have been placed in my 2019 California Special Edition Mustang, and both are bad. They both came from the Ford manufacturer. The transmission locks up at any point while driving at any speed, causing the car to jerk to a standstill, and only while you are driving. We were on 465, and the car automatically stopped in the middle of the highway while other vehicles were flying by and behind me. We were almost hit by several vehicles. This also occurred while the mechanic test drove the car with the second rebuilt transmission placed in my car. No warnings, nothing before this occurred. This is a huge safety hazard and risk for many. The dealership is aware and advised me to contact Ford Motor Company and not to drive my car until something can be done. I have contacted Ford Motor Company, and they have yet to do anything or reach back out to me regarding this safety issue. The car is available for inspection at any time needed since it is still sitting at the dealership with the second rebuilt transmission in it that is no good.
My 2019 Ford Mustang Ecoboost Premium Fastback is having an issue with the transmission. When I shift from park to reverse or from reverse to drive, the car makes a clunking noise. There are times when i do a doubletake in my rear view mirror to see if someone has hit me in the back, this happens sometimes when i shift into reverse. Also, I have to stay back at least a car length behind vehicles as the car will sometimes lunges forward which can cause an accident. Will be taking my vehicle into service for this problem.
The contact owns a 2019 Ford Mustang. The contact stated that it was difficult to start the vehicle. While driving at 30 MPH, there was a significant amount of white smoke coming out of the exhaust pipes, reducing the visibility of the rear of the vehicle. The contact was able to pull over to the side of the road. The vehicle was towed to the dealer, where it was diagnosed, and it was determined that the engine was blown. The dealer determined that the engine needed to be replaced. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 44,000.
The car is using a lot of engine coolant and oil. It is also burning the spark plugs. The check engine light comes out 6k miles after I install new spark plugs and it starts shaking, misfiring, running poorly, not accelerating properly and blowing white smoke through the exhaust on cold start. I know the engines have a defect from factory that causes them to do this. It usually needs a new head gasket, block or engine. Please advise. I read a forum that referred me to this website. The car is well taken care of and has 115k miles.
Description of the Defect: My 2019 Ford Mustang EcoBoost experienced a premature engine failure caused by internal coolant intrusion, resulting in the need for complete engine replacement. This failure is not related to routine maintenance or a head gasket issue, but rather a known internal engine design defect that allows coolant to intrude into the cylinders over time. The vehicle exhibited symptoms including coolant loss without visible external leaks, rough operation, and engine malfunction. Upon inspection by a Ford dealership, the failure was diagnosed as coolant intrusion into the engine, with the only repair option being long‑block (engine) replacement. Ford has acknowledged this failure mode in Technical Service Bulletin (TSB) 19‑2346, which documents coolant intrusion in EcoBoost engines and states that engine replacement—not head gasket repair—is the required corrective action. This bulletin confirms the issue is caused by an internal design flaw that develops over time. Why This Is a Safety Concern: This defect can lead to sudden engine misfires, loss of power, or complete engine failure while driving, which poses a serious safety risk to vehicle occupants and other road users. Engine failure at highway speeds or during normal driving conditions creates the potential for crashes, loss of vehicle control, or roadside breakdowns in unsafe conditions. The failure occurred at very low mileage (~36,000 miles), indicating a premature and abnormal engine defect, not normal wear and tear. Yes, it is available for inspection upon request. Yes, it is diagnostic and confirmed by AutoNation Ford Bellevue [XXX] Direct line: [XXX] No, prior warning and symptoms. First appeared on March 16, 2026. No recall exists despite Ford’s TSBs acknowledging the defect. Ford later redesigned the EcoBoost engine, showing awareness of the issue, yet owners are forced to pay for costly engine replacements after warranty expiration.

The rear backup camera on my 2019 Ford Mustang intermittently stops working. At times the screen shows a blue screen or displays a “backup camera not available” message. The issue comes and goes without warning. This creates a safety concern when reversing, as visibility is reduced and the camera cannot be relied upon. The problem appears to be electrical and is not consistently functioning.
Refused to fix the issue because the OBD reader did not provide any codes OBD reader is not sending any signals, but there is power I called Sam’s Ford to send a service to fix the recall but told me they will not fix the issues because no codes were being provided And the check engine light is active
The contact owns a 2019 Ford Mustang. The contact stated that the passenger’s and driver’s side door latches unlocked while driving approximately 70 - 75 MPH, and the doors became slightly opened. The contact grabbed the interior handle and closed the door. The contact had received information related to the door lock failures. The vehicle was taken to the dealer, and the contact was informed that the vehicle could not be repaired under recall because an undisclosed campaign had expired in November 2025. The vehicle was not repaired. The manufacturer was informed of the failure by the dealer and confirmed that the recall campaign had expired. The failure mileage was approximately 144,000.
The component that failed on my ecoboost mustang 2019 was a failed design in the motor called the head gasket. The head gaskets broke and started leaking coolant into the engine. The engine has 39,000 miles
While driving at normal road speed, the vehicle suddenly displayed multiple warnings at the same time indicating that AdvanceTrac (electronic stability control), traction control, and ABS were disabled, and the vehicle entered a reduced functionality state. These warnings appeared simultaneously without any hard braking, loss of traction, or driver input at the time. The warnings and system faults then cleared in a cascading manner over a short distance, with each system returning one after another while continuing to drive, without shutting off the engine. After approximately a few thousand feet, all warning messages disappeared and the systems appeared to return to normal operation on their own. This has occurred more than once since ownership. The first occurrence happened at approximately 50 mph. The second occurrence happened at approximately 20 mph and occurred only seconds before an emergency braking event in the rain to avoid a collision. At the time the warnings appeared, the vehicle had temporarily lost ABS, stability control, traction control, and related braking assistance systems, creating a serious safety risk during an actual emergency maneuver. After the events, an OBD-II scan was performed and no stored fault codes or diagnostic trouble codes were present. However, for the next several engine on/off cycles, the steering and traction control behavior felt abnormal, as if the systems were only partially engaged, even though no warning lights or messages were displayed. No permanent warning lights remained illuminated afterward. The problem is intermittent and difficult to reproduce. No collision occurred, no repairs have yet been performed, and the cause is currently unknown
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.
