1 Hazard Flashing Warning Light Unit problem of the 2005 Chevrolet Trailblazer

Failure Date: 06/01/2018

The headlights go off after a while of use as if the over heat and go off once they cool off they come back on but they go off after about 15 mins of use. Only the brights will work at this time. So not only is it a safety hazard to me that my lights just go off out of nowhere then I have to turn my brights on which is a safety hazard to other people and against the wall you have a recall on the 2006 model for the same problem why would you not have the recall on the 2005 model that obviously has the same issue they go off on back roads they go off on the highway they go off in the city they go off in the country they go off anywhere that I'm driving anytime that the headlights are on that will go off after about 15 minutes of use whether the car is being driven or it is stationary. This imhas been a problem with this car for many years but I just recently bought it for myself and I feel it's an issue that you all should resolve I have looked online and there a lot of people having the same issue.
