I have the P/S Warning light, Check Hybrid System, Check VSC, Check AWD, BREAK, ABS, TRAC LIGHT. I am experiencing intermittent Power Steering loss I had 2006 rx400h 215,000 miles on the dot I disconnect the battery and turn on and off ignition 4 times and it works but it is not good when I’m driving and lose power steering do you think this is the relay or the computer or something different entirely
