Power steering went out completely causing me to swerve on the highway to side of road. The steering locked up and it was raining and I would of crashed had anyone else been on the highway. I was going about 55 mph at the time. I then proceeded to CAREFULLY at about 30 mph force my car to drive another half mile to nearest exit ramp. The entire time I was driving in the middle of the lanes and a huge liability as far as safety is concerned. Thankfully I made it with no harm to myself vehicle or anyone else. I pulled over to side of road and slept in car till the rain stopped. Prior to this I backed into a fence when the steering failed backing into a carport resulting in body damage to front end under left headlight. Months before I had asked the Chevy dealership to diagnose issue and they found nothing wrong as in the beginning the car would still steer at its own leisure. The light didn't come on when they looked at it. After the night in the rain I have taken the fuse outta the power steering part and just manually steer. This should be replaced as it is a common issue to ALL HHR. Mine isn't covered as it is an SS but clearly it should be covered by a recall. Hopefully I don't die before this is taken care of.
