2004 Supercharged model with only 14,300 miles. In the winter, it is garaged and I am the only driver. I just had a new instrument cluster installed about 200 miles ago. This last month while pulling it out on a clear day (dry pavement), I noticed that the steering wheel has changed-appeared are 3 lines, 120 degrees apart and basically it looks like the assembly under the leather (horn and air bag), want to come out or that the leather has taken a set around what I can only think is a set of hinges for the deployment of the air bag. So, it unnerved me. Nothing like thinking you are tooling down the road and the bag decides to deloy.
So, I took it to the dealership from whom I purchased the vehicle. Since the air bag light is not on, they said no problem. Also, since they had no wheels in stock there was no way to compare it. Phone calls to various dealers finally yielded somebody who said they had a spare with the same situation. I disagreed since I know my car and had a pic in the 2004 brochure of the car when I purchased it. There are no lines showing anything underneath the skin.
I think my only recourse is to find Impalas and Monte Carlos with the same vintage year (2004-5) and use them as examples. This car spends as much time going to the dealership as well as around town. They tried to stick me with the failed instrument panel so I do not have a high regard (currently) for what they say.
