Great info on this thread, I have a 2017 edge with 52,000 with the dreaded coolant intrusion issue. No warranty. 
 
	I barely put 100 miles on it in week, so watching the coolant tank is not a problem for me.
 
	The car runs fine, sometimes a slight stutter at startup and fuel economy is down <10%.
 
	But my question is:
 
	Will this crack get bigger and cause the performance and drivability to worsen?
 
	 
 
	Can't afford a 8k repair at this time, thinking of driving it for a couple of years than trade it in.
 
	 
 
	Thanks in advance
 
	Dawg
