One problem related to radio/tape cd player has been reported for the 2007 Chevrolet Suburban. The most recently reported issues are listed below.
The odometer instrument cluster went out on my 2007 Suburban and the radio is changing stations on its own. Also the metal trim on my door handles and heating/ac controls is peeling apart and cutting my hands. In addition, the engine burns oil and I have checked it out by three different dealers/mechanics and they cannot find any leaks. I have seen a lot of similar complaints and I believe chevy should repair these items at no cost to owners.
