Have this 2010 check impala. Unfortunately there is a wiring issue in the shifter. This led me to try to diagnose the issue. Hence why the radio is missing in the photo. I will continue to attempt to fix the shifter until sold. There is also issues with the front bearings. They need replaced and Chevy quoted it at 500. The shifter they want to do a full replace. I promise that it is a simple wiring issue and could be fixed if someone (besides me) knew what they were doing. Chevy wanted almost 800 for the full replacement. Car also has a loud exhaust due to an accident a few years ago. Insurance replaced the bumper but not the exhaust.
