Whenever I connect a trailer to my vehicle I will lose all brake pressure when in reverse. It only happens when in reverse and connected to a trailer. I will have to pump my brakes to the floor and there's no braking power. This does not happen when I do not have a trailer connected.

I was towing a camper down Rt 422 in Butler, PA in my GMC truck when it suddenly caught fire. My wife was following me and alerted me to pull over as quickly as possible. I had no brakes and the gear shifter went straight up without shifting. The doors would also not open while the truck was filling with smoke. I got out using the manual unlock knob and am lucky to be alive. We had about one minute to try to extinguish the flames before it fully engulfed both my truck and camper. I filed a complaint with GMC. By what I am reading online there are many instances of fires and GMC does not seem to provide assistance. This is very unnerving and scary to say the least. I am sad and angry for this situation. This happened through no fault of my own and I lost absolutely everything. I was in the middle of moving to start a new job and lost many work items in my truck as well. I had to delay my start date for work. Now I am responsible for deductables, insurance increases and other items not covered by my insurance. Now I have to buy a new vehicle and camper but what will GMC do to help me? Probably nothing.

THE HEADLAMPS ON MY VEHICLE HAVE BEEN VERY POOR, BOTH IN LOW AND HIGH BEAM POSITIONS EVER SINCE I PURCHASED THE VEHICLE. THINKING THAT THEIR MUST BE SOMETHING WRONG WITH THE EXISTING HEADLAMPS, I PURCHASED THE REPLACEMENT BULBS AND THERE WERE NO IMPROVEMENTS. WHEN DRIVING AT NIGHT I HAVE TO STAY ON LOW BEAM WITH THE FOG LIGHTS ON JUST TO HELP TO SEE. I CAN'T USE MY HIGH BEAMS AT ALL BECAUSE THE LIGHTING IS SO POOR. GMC IS AWARE OF THEIR HEADLAMP ISSUES ON THE 2014 AND 15 MODELS BUT NOTHING IS BEING DONE ABOUT IT TO MY KNOWLEDGE. WITHOUT SPENDING $500-$1000 TO CHANGE THEM OVER TO LED, IS THERE ANYTHING THAT I CAN DO TO IMPROVE THIS SITUATION?

WHILE GOING SLOWLY AND TURNING, MY BRAKES FAILED TO STOP ME. THERE WAS NO PRESSURE FOR THE BRAKES. THIS HAPPENED SEVERAL TIMES. I ALMOST RAN INTO THE BACK OF A CAR.
