NHTSA Complaint #11668404 — 2015 FORD FUSION

I changed my battery at 105,000 miles with everything working fine electronically for my 2015 Fusion. Been a great car up to this issue. After installing the correct battery, the power steering turned off and hasn't come back on. Took to dealership, they replaced a connection cable at their suggestion and still were unable to reset the power steering. That's where it should have ended tho. They want me to further come back to run more tests??? Something seems very defective to me and from social media reports of other Fusion owners and the nhtsa investigations, a power steering recall should be warranted. I have been a car owner for 40 years and never experienced this inconvenience. I think Ford is getting away with inferior electronics and passing the expense back to the consumer. It should be an easy fix but not one at $4000 (getting a new steering rack) just to change a battery?? :-( Please help!
