Entire electronic panel lights up. Returned to local Mercedes Benz Dealership. It took two-weeks to resolve problem, and the final cost $4,800. Now the door locks rapidly goes up and down; the keyless entry no longer works. The estimated repair cost for this annoyance was quoted as $1,500. No thanks, I'll live with the noise.!
