While giving my 2009 G3 Wave a thorough cleaning recently I discovered what I think is a major flaw in the front right fender. See if you are missing this part too. Open the front passenger door. Just in front of the door hinge on the body there is no rubber insulating panel that should close and seal the inside of the fender. As a result, dirt and other debris gets trapped inside the fender. On my car this cavity contains a considerable amount of wet mud. I think this will significantly shorten the life of that fender... it will promote rust from the inside out. Compare this to the front left fender and the black rubber panel is in place.
I asked my GM dealer about this and after a lengthy search through their manuals, parts catalog and service bulletins they concluded that the part does not exist. That is how these Aveos and Waves were made. They suggested I call GM directly about this to see if there is a fix or if there is one planned.
Have you noticed this on your car? Please check and see. If the rubber panel is absent on your car is will be easy to spot... there will be an open space inside your fender from the bottom to the top. Compare to the left side.
Please reply to me if your car is the same and maybe as a group we can get GM to address this.
