This usually happens when gas is not being applied. The headlights, radio, ac, will go off and on. I then noticed the abs and esc light. It does seem to get worse the longer it is driven. I have researched and see that a lot of other people are having the same problem. I had the car in shop last week for 4 days. They said that they were unable to locate what was causing the problem. Hyundai according to previous comments have been made aware of the problem but are doing nothing!! Please help.

Trying to find someone that can help cause when I press the brakes, the parking lights and dash lights come on and when you let off they go off, then when you turn on the park lights it looks like that the brake lights are on....

tried replacing the brake switch but didn't fix the problem.. Can someone please help

Someone please tell me how to fix this problem. Headlights dim, radio cuts off, aux plugs cut off when you let out of the gas. I have replace the alternator, battery, had the grounds checked and tightened. Please help!!!
