Welcome to the forum.Same exact story. I have a 2014 1.6 escape with 79k miles. This can’t possibly be random. Is there a process to qualify this issue under a recall? I just replaced the engine on ford’s recommendation, drove it home, received the same exact ‘engine coolant low’ message from months ago.
Please note the TSB this thread is about relates specifically to the 1.5l EcoBoost in 2017-2019 build Escapes.
The forum search function (or Google) will bring up a lot of hits for recalls and TSB's for the 1.6l EcoBoost engine. Specifically related to coolant system problems and changes to the coolant hose routing/ PCM updates.
