NHTSA Complaint #11615320 — 2016 FORD EDGE

We are Canadians live in Calgary, AB Canada. We have a 2016 ford egde. There was an engine warning sign popped up when we had a road trip in US days ago. We also noticed that the car chokes when cold start with white sweet smoke come out. We had the car checked up by a ford dealer at coos bay, Oregon. Here is the diagnostics - dtcp0303 stored related to cylinder 3 misfire - found engine coolant level low - topped off coolant and pressure tested system - found pressure to bleed off abnormally - no external leaks observed - removed aprk plug and bore scope cylinder - verified coolant intrusion in cylinder 3 also found signs of burning coolant on spark plug - recommended repair is long block replacement. We cancelled our unfinished trip and struggled to drive 2000km back home(low speed, keep checking/adding coolant and engine oil). The local ford dealer quoted me 10k CAD to replace the long block. Our car is not even 8 years old at 130K kms. I called Ford Canada and was told they are sorry but the car is out of warranty and no recalls. Although there is a TSB#22-2229 which proves this is a known issue to Ford. I spent some time search on line found many ford owners had same experience and referred by them to post a complain here.
