I own a 2014 GM Sierra SLE
I own a 2014 GM Sierra SLE and don't like to drive it at night.
Worst headlights of the 16 vehicles I have owned in my life.
I did email GMC on 4/6/15 and received a response within 1 day.
They hooked me up with the dealer I bought it from whom noted that GM is coming out with a different headlight bulb and reprogramming.
They do not have the parts yet so we will see if it ever is corrected.
