Lose Power Steering problems of the 2016 Ford Transit Connect

While pulling out of a fast food drive through steering jerked to center and I lost power steering to the point where I could barely keep control of the vehicle, mechanic informed me the powering steering motor seemed overheated because of its location and I could expect this to happen again, on the dash I got a "steering fault" code. Second issue unrelated is that the temp sensor keeps malfunctioning, once the senor reaches below the freezing point on the dash ( keep in mind its 74f outside) the vehicle shuts down the air conditioning unit blowing hot air until the whole system resets and the dash reads the actual exterior temp. New Ford temp sensor installed worked fine for two weeks then same issue. Its frustrating when we reach 80+ degrees and the air conditioning is intermittent because of a senor issue which is totally unrelated to the unit itself. Two other friends of mine own the same year vehicle and are having the same issues. Love my Ford but they should own up to they're problems.
