Recently our 2007 HHR began behaving strangely. All the lights and error messages possible were flashing through the Driver info Center. I read the codes and they were communications related. I reset the codes and it was good for about a week. Then after the second event we took it to the Dealer. There we learned that it was not covered under the power train warranty. The kept it for half a day and could find nothing wrong with it. On the way home it went brazerk once again. I took it into my shop and found a corroded terminal on the battery. After inspecting and cleaning several grounds I felt I had the problem resolved. Several days later the problem returned but this time the power steering also failed amidst all the flashing lights and dinging. I cannot get the dealer to fix it, I cannot get a service manual and I am having no luck finding anyone at Chevrolet that cares. I currently have 5 Chevrolets from 1925 to 2007. This may be the one that sends me to another manufacturer.
