This has continued to be an ongoing problem. I have taken it back to the dealer twice as it is becoming a safety hazard but they "cannot replicate" the problem. They state they have reports of the interior lighting dimming on some vehicles when they go through a tunnel, but then it corrects when they emerge. My car does this driving down the highway on a sunny day, it does it coming out of the parking garage into the sunlight, it does it at night, there is no rhyme or reason but I would say it is doing the "dimming of all control lighting" at least twice per month, which is dangerous to drive...not so much if you are in a familiar area, but if you are depending upon your navigation, and/or your speed control on an interstate hwy - this becomes a safety issue. I don't know where else to turn as my dealer just keeps shinning me on -probably because I am a female owner.
