New TSB 19-2172 released today pertaining to coolant loss and misfiring issues with the 2.0L EcoBoost engine. Once the issue is confirmed, the engine will have to be replaced.
Issue: Some 2015-2018 Edge vehicles, 2015-2019 Fusion/MKZ vehicles built on or before 8-May-2019, 2015-2019 Escape vehicles built on or before 15-May-2019 and 2015-2019 MKC vehicles built on or before 17-Apr-2019 equipped with a 2.0L EcoBoost engine may exhibit a low coolant level, white exhaust smoke and/or a runs rough condition with or without an illuminated malfunction indicator lamp (MIL). Diagnostic trouble codes (DTCs) may include P0300, P0301-P0304, P0316, P0217, P1285 and/or P1299 stored in powertrain control module (PCM). This may be due to coolant intrusion into the cylinder. To correct the condition, follow the Service Procedure steps to replace the long block engine assembly.
Service Procedure
1. With the engine at normal operating temperature, pressurize the cooling system to 138 kPa (20 psi) and hold for 5 hours. Refer to the coolant pressure test in Workshop Manual (WSM), Section 303-03A and check for cooling system combustion gases.
2. Did coolant system pressure drop more than 27.57 kPa (4 psi) after 5 hours?
(1). Yes - proceed to Step 3.
(2). No - this article does not apply. Refer to the Powertrain Control/Emission Diagnosis (PC/ED) Manual for normal diagnostics.
3. Remove the spark plugs and, using a borescope or equivalent, inspect and determine if coolant has entered the cylinders.
4. Is coolant present in any cylinder?
(1). Yes - remove the engine and replace the long block. Refer to WSM, Section 303-01A.
(2). No - this article does not apply. Refer to WSM, Section 303-01 for normal diagnostics.
