Power Steering Fluid problems of the 2008 Ford Edge

Power steering fluid leaks due to ptu going out.

I always maintained my "pre-owned" vehicle, purchased from dealership with 25,000 miles. Began to experience a plethora of problems after 2,000 miles. I've paid over $8,000 in repairs and only drove it 35,000 in 8 years time, but maintained it properly & regularly: I've had to change the brakes & pads, & battery twice, it's wheel rims constantly leak air in the winter causing flat tires, changed all 4 tires, and on August 2, 20017, while driving on the highway at 60 mph, my steering control suddenly locked up! there was no control over the vehicle's movements- no ability to make lane adjustments or turns! I and my entire family including grandchildren could have been killed!! luckily, the next off-ramp was a straight shot & I was able to exit the hwy safely and bring the vehicle to stop despite no steering control. I had my vehicle towed to a Ford dealership which incorrectly diagnosed the problem, & did not bother to inspect it for three days. It now needs a costly ($1500) rack and pinion to replace it's rusted out pressurized fuel line for power steering fluid. It remains unrepaired to date since there is also a takata airbag recall w/ possible fatal injury on this VIN. The repairs have been delayed because this vehicle is an unsafe danger to drive! the fuel line defect was undetectable even though I had regular maintenance care and checkups.
