New member here, but have been driving a 2018 F150 powerstroke for 2.5 years. Have loved it up to this point and had 38,000 miles on it. Three weeks ago, the oil pressure started showing zero with the engine warmed up and at a stand still. If placed in park or started moving again, normal oil pressure resumed. Immediately took it to dealer. They replaced the oil cooler and conducted the latest EGR recall. A week later, we started a pre-thanksgiving road trip to see the Grand Canyon. While doing 80 mph on I40 back into Flagstaff, the engine seized. Still waiting to find out what caused the seizure, but has anyone else experienced anything like this?
