Symptom: The coolant level drops with no leak, there's a rough idle when cold, misfire codes P0301–P0304 appear, and white exhaust smoke shows at startup.
Likely causes
- Coolant getting into the cylinders. Ford's bulletin calls for a new long block, not just a head gasket. Ford Edge Forum owners report misfire and rough-cold-idle patterns, and some have had it come back.
- External leaks, which should be ruled out first.
DIY or shop?
Shop. Do a pressure test and a cylinder leak-down test.
Useful steps
- Watch the coolant level weekly.
- Ask the dealer whether your VIN falls under the bulletin and whether any extended coverage applies.
- Don't keep driving on low coolant.
