I just bought this used car this month. While driving at night, my lights decided to just go off on low beam, I had to put on high beam. The low beam light continues to go off and on? Annoying and potentially dangerous!. I did some research and discovered that there was a recall on these particular make and model for this issue. I am hoping to get this corrected since it under recall status. Any ideas of who I can contact?

Lights did not come on that night and had to use highbeams to get home. Had the module tested at my work and results were passed. Later on that night the low beams came on and stayed on until this evening when I went to go out at night. Will research this intermittent problem and possibly try to follow a schematic tomorrow in the hopes of a solution.

Update from Nov 12, 2015: Lowbeams still go out after fifteen seconds of auto moving forward.

I have to replace the HDM Module on my 2008 Pontiac Grand Prix twice. The headlights would not work on dim. This appears to be an issue is with more than just my car. It appears that they should do a recall and fix the problem.
