Ok, I have had my '06 hhr for about three and a half years now. I have had recently now a problem with my power steering going out and then coming back, also with the light on the dash comes on/off, and sometimes the security light comes on as well, and once that is on that will not go off until we shut off the vehicle and then restart. I have already had my husband replace my power steering motor and that did not solve the problem, we already replaced a relay under the hood as well. I am at such a lost, that I am about to take it to the dealer and spend the $100.00 for the diagnostic test just to see if something comes up on the Tech II.
