Steering Rack And Pinion problems of the 2006 Ford Escape Hybrid

Electric assisted power steering not functional. Dealer troubleshooting consisted of reading codes, then indicating that the entire rack and pinion assembly needed replaced ($2200). Replaced the assembly, still doesn't work. The electronic steering control module was replaced, still doesn't work. The repair shops and the dealers have inadequate information and training to repair these electric steering systems. There should be adequate information and training to identify the failed component, as opposed to swapping out large assemblies, and still not fixing the problem. These systems appear to have a high failure rate, and present a huge safety issue when they fail while driving! please issue a recall ASAP!.
