Have a new Smoke LE, called the dealer and they did not know. When we turn on the back interior light it is bright, but then when we put on the second one on all four come on and are very dim. This is the same when the vehicle is on or off. Also traded in our Avalanche for it. The head phones have static, where in the Avalanche they were not. Again the dealer said to bring it in they did not know. Any one have any simular problems? Just have to note we tested a lot of vehicles including the 2007 Tahoe. The Armada won hands down. What a fantistic Transmission.
