On approximately September 28, 2026, the vehicle began sputtering when first turned on. It then progressed to running extremely rough. On September 30, 2026 the Engine Icon lit up first. A few days later, I received an Engine Fault Service Now message. I went to the Auto Zone on October 4, 2026 and they ran a diagnostic check. These are the codes that were found: Check Engine Fail Replace Ignition Coil and Spark Plug #3 P0303 Cylinder 3 misfire detected P0339 Crankshaft Position Sensor A Circuit Intermittent...

P0300 Random misfire detected Cylinder 3 On October 5, 2026, I took it to my mechanic and he began checking everything. He found oil on and inside the computer. He also found that there was antifreeze residue on the Cylinder and Spark Plugs. He did some research to find out what could cause this to happen. He found the following: 1,134-1,711 engine complaints depending on dataset. Failures typically occur between 50,000 and 100,000 miles. Main Engine Problems 1. Coolant Intrusion (1.5L EcoBoost - Most Common & Severe) Coolant leaks past the block/head sealing surface into cylinders. Not a head gasket failure - requires short-block or long-block replacement. Symptoms: Misfire codes (P0300-P0304) White exhaust smoke Unexplained coolant loss Rough idle, stalling, overheating. 2. Cracked Engine Block Often the end result of prolonged coolant intrusion. Leads to catastrophic engine failure requiring full replacement. On Friday, October 9, 2026, I drove my car to work, approximately 2.5 miles, after the Escape sitting for 3.5 hours, I started it. I immediately received the HIGH ENGINE TEMPERATURE STOP SAFELY, and the engine shut off. On the 3rd try, the Escape stayed running. I could only drive 11 mph. On my final turn onto a busy street, the Escape began sputtering and would not accelerate at all. I was stuck in the middle of the street, putting myself at risk of being hit. I finally made it to a parking lot but had to be pushed home by my son.
