Just took my 2018 edge with 2.0!eco boost back to dealer. First took it in about 6 weeks ago when check engine light came on. Didn’t notice anything going on.
codes P0316 and P0304. Diagnostics indicated coolant in cylinder #4, almost no coolant in radiator. I’d had the oil changed at dealer about 1 month and a 1000 miles before with no indications of trouble. Complete long block engine replacement. I noticed a bit more power. Now 1 month later and possibly 1000 miles check engine light back on. No misfire or poor running. At dealers since 12/20. Said they were backed up and would be after Christmas before they got to it. I’m hoping it’s a fouled cat. Converter or oxygen sensor.
