For 5 months the headlights work when they want to, the first couple months they were working more than not, last couple months they were not working more than they did work.

Headlight drive module (hdm) controls both low beam headlights. This relay has failed on me twice in less than a year, at night resulting in going down the road with no lights and unable to see. Vehicle was in motion on a highway going 55 MPH at night

On december 20, 2015 we were traveling after dark (7:30 pm) and the head lamps went off. We managed to pull out of traffic safely. Could not figure out what happened. After sitting for approximately 5 minutes the lamps came back on and we were driving to our home and the lamps went off again. I took the vehicle to a chevy dealer and they could not help me. I then called the gmc dealer and got the same response. I then checked online and found out that gm knows of this problem which is caused by a headlamp module overheating. I know this problem is occurring to other people so why hasn't there been a recall.? Help.
