2006 hyundai azera limited - i have a problem with the head lights and dash board lights dimming on and off randomly for about one year now. the problem does not happen if you are on the highway going about 60+ mph. i've brought my car into 3 dealerships. the 1st dealer said it was the battery harness which they changed and didn't solve the problem. they also wanted to sell me a new battery. the 2nd one said they'll never find the problem and save my money and take my wife out to lunch or trade the car in, and the 3rd dealer said they heard about the problem and fixed it once but can't remember how. the problem is a safety hazard and hyundai should find a fix. *tr
