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.

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.

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.

POWER TRAIN — Filed 04/06/2026

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 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.

AIR BAGS,LANE DEPARTURE,FORWARD COLLISION AVOIDANCE — Filed 09/29/2022

My name is Michelle Wright and I have purchased Ford vehicles most of my life. I love Ford vehicles and have had amazing experiences with Westlie Ford and Landmark Ford. I purchased my vehicle at Vancouver Ford, which is the most unprofessional and unethical dealership. My story starts October 2021, when I purchased a 2019 Ford Mustang from Vancouver Ford. I paid cash for the vehicle and was provided an AutoCheck, not a Carfax the day I had purchased this car. Over the last 8 months I have had several issues that made think my car was an accident but was assured it was never in an accident. After pulling the Carfax, I realized it was in a wreck and had an accident date of July 2019. This led me to look for an accident report, which was filed by a Portland Police officer on July 23, 2019.

STEERING,UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE — Filed 11/27/2021

On 11/27/21 I was driving my 2019 mustang GT convertible with approx 15,000 miles. While going around a curve (not at an excessive speed) on dry pavement, the car became uncontrollable and began to spin out. As much as I tried to brake and steer into the slide, the car became more and more uncontrollable and felt as though it were speeding up. I only came to a stop after slamming into a tree and rolling over to the other side of the road. Vehicle is a total loss. I was lucky and only suffered minor injuries, but it very easily could have been much worse. The police and paramedics who arrived at the scene were expecting a fatality or severe injuries. In the end I was ticketed for failure to reduce speed. I'm losing my mind explaining to the police and insurance that the car sped up on its own and all control of the vehicle were lost. I am in danger of losing my license because of this and no one is believing that this could possibly happen and convinced me to state that I was probably driving too fast. This is a deadly problem. The internet is full of videos demonstrating this same problem: complete loss of control in a low speed turn. Before you ask, I wasn't racing, I wasn't drifting, I wasn't spinning my tires or doing donuts; I was just trying to go home to my kids who almost lost their father. If there is any saved data or physical evidence that needs to be saved, action is needed ASAP before the insurance company scraps it. Also, it should be noted that in the week leading up to the accident, the rear end would become loose when going around corners. I had planned to have it addressed at the next oil change.
