What owners say about the engine
Verbatim from NHTSA complaints, newest first
“A blank instrument cluster will not show important information like vehicle speed, fuel or temperature level, or safety system warnings. Gas pedal doesn't act and doesn't even effect the car's engine. And suddenly it catches up and jerks.”
“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.”
“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.”
“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.”
“The contact owns a 2019 Ford Mustang. The contact stated that upon start the check engine warning light was illuminated. The vehicle was taken to a local dealer where it was diagnosed and the contact was advised that the engine was faulty due to coolant intrusion and that the engine would have to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 95,000.”
