NHTSA Complaint #11675077 — 2018 FORD EDGE

Computer error P0304 - misfiring in cylinder 4. Diagnosed with a coolant leak into the cylinder. Potential Safety Issues: Loss of Power: A misfire can cause sudden power loss, particularly during acceleration or at high speeds, increasing the risk of accidents, especially in traffic or on highways. Engine Stalling: If the misfire worsens, the engine may stall, leaving you unable to control the vehicle, which is dangerous in busy areas or intersections. Overheating Risk: Coolant intrusion into cylinder 4 (as noted in TSB 22-2229) can lead to overheating if the cooling system is compromised, potentially causing engine failure or fire hazards. Catalytic Converter Damage: Persistent misfires can overheat and damage the catalytic converter, potentially leading to a fire risk under the vehicle. Beyond this, it is my 17 year old daughter driving this car and she could be stranded some place unsafe due to not starting or in the middle of traffic while driving. It has been inspected by a mechanic to confirm the leak. Ford's issuing of a TSB on this issue (TSB 22-2229) - calls for a new engine. Ford knows they have made faulty engines in these cars and refuses to help cover the cost of replacement.
