Having difficulty with driving vehicle. Seemed to be over road. Several evaluations at car dealership, different fixes without resolutions. Finally the air system which regulates the balance, height etc stopped functionally. The car sits low to the ground. I first started complaining of unusual noises from the speakers of the car. Approximately 9 months ago. Dealership did not know what that could be. Now I am told the compressor and the shock system is gone. The cost to fix is $3000 I have found a company who has an adaptive kit with conversion to standard shock system. This company tells me that they are sedmomg 15 to 20 of these kits out a week. GMC does not offer any options. My concern is this has been a problem for multiple months without the dealerships ability to find the problem in a timely manner. The car was rendered unsafe to drive because it was hard to steer and difficult to keep in your own lane. Additionally, the gas gage has gone bade, approximately 50,000, the first Rainier I had there was a problem with getting the fuel into the tank. Traded the 2004 for 2005 because of this problem. Now this gas tank the gauge is defective.
