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, thereâs 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…

Known engine coolant intrusion problem with the Ford EcoBoost engine. It misfires and was confirmed by a service center that a whole new engine was needed. Car shaking and rumbling-- gas smell. Afraid of it catching fire.

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 â coolant intrusion cylinder 1, P0316, P0301.â Apparently it's a known issue with this particular engine and has a pending lawsuit.

Upon start up the digital cluster remains blank. This happens often now. 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…
