The power steering assist warning happens, the engine temperature gauge stops working, the engine auto stop quits working and the AC clutch will not engage all the same time. This has happened three times recently. After a period of a day or three it resets and everything works correctly. It happened once while my son-in-law was driving, it reset the next day. It happened while I was having the car detailed, it reset two days later. It happened two days ago while I was driving the car, my wife pressed a button on the AC system to adjust the vents and the problem occurred and has not reset as of yet.

This is not dangerous, but not having AC in Louisiana is unacceptable. I fear this is going to be a difficult problem to discover the cause, I suspect software issues.
