NHTSA Complaint #11459941 — 2010 FORD TAURUS

5 April 2022 my 2010 Taurus SEL 3.5L engine overheated unexpectedly and the temp warning light came on my way home. I let it cool down during a heavy rain before heading home. I left the vehicle at a gas station for a couple of hours and return to bring it home (3 miles). Temp gage remain steady (3 miles) until it was parked on my driveway. The next day, I conducted an assessment to the cooling system. Reservoir was completely empty and my oil deep stick level was higher than normal 1 inch above max range. It showed coolant contamination. I read several reports about a flaw with the internal water pump design. If indeed is a flaw design or pump manufacture defect, why Ford Motor Company hasn't fix the issue or provided a solution to alleviate this flaw? Now I have to incur on major engine repairs or replacement, in which I am not sure if it is cost effective. Current mileage 171,424
