THEY COULD BE POSSIBLY DESIGNED FOR STATIONARY USE IN A PERFECT ENVIORMENT BUT NOT FOR MOVING VEHICLES, I CANNOT SAFELY DRIVE THIS VEHICLE AT NIGHT, I FEAR NOT ONLY FOR MYSELF BUT FOR OTHER PEOPLE ON AND NEAR THE PATH OF THIS VEHICLE. MY MIND IS CLEAR, THERE ARE MANY BLOWING THE WHISTLE.

I HAVE BEEN HAVING A PROBLEM WITH THE TRAILER BRAKE CONTROLLER ON MY K3500 TRUCK. RECENTLY THE MESSAGE "CHECK TRAILER WIRING" HAS BEEN COMING ON FREQUENTLY. AT THE SAME TIME, THE BRAKING CONTROLLER SHUTS OFF POWER TO THE TRAILER BRAKES. THIS HAS RESULTED IN A VERY UNSAFE CONDITION, ESPECIALLY WITH A TRAILER THAT WEIGHS OVER 14,000 POUNDS. THIS HAS BEEN GOING ON FOR 6 MONTHS NOW. REPEATED ATTEMPTS BY BOTH THE GMC DEALER AND THE TRAILER DEALER HAVE FAILED TO RESOLVE THE PROBLEM. I HAVE BEEN TOLD, BY THE DEALER, THAT THE PROBLEM STARTED APPROXIMATELY WITH THE 2014 MODELS. THE BRAKE CONTROLLER HAS BEEN UPGRADED, AND MADE MUCH MORE SENSITIVE TO SLIGHT DEVIATIONS IN THE TRAILER SYSTEM, CAUSING THE CONTROLLER TO "SHUT OFF" SO TO SPEAK. WHILE THIS WOULDN'T BE A BIG ISSUE NORMALLY, WHEN IT SHUTS OFF, YOU LOSE ALL BRAKING ABILITY TO THE TRAILER RESULTING IN AN UNSAFE CONDITION. THERE IS NO WAY TO OVERRIDE THIS AND ACTIVATE THE BRAKES. WHAT SEEMS TO BE HAPPENING IS A VERY SLIGHT DEVIATION IN THE RESISTANCE IN THE TRAILER BRAKE SYSTEM (BY 1 OHM OR LESS) AND THAT CAUSES THE "SHUTDOWN" IN THE CONTROLLER. TRAILER BRAKES WOULD WORK, IF THEY COULD GET POWER. BUT, THE CONTROLLER HAS SHUT DOWN, SO NO POWER. MYSELF (AND THE TRAILER SHOP) HAVE BEEN CHECKING THE INTERNET AND FINDING THAT THIS IS NOT AN ISOLATED INCIDENT. IT APPEARS TO BE HAPPENING WITH ALL THE BIG THREE MANUFACTURER TRUCKS, SINCE ABOUT 2014. PEOPLE HAVE BEEN COMING UP WITH SOME RATHER "CREATIVE" WAYS AROUND THIS, IN SOME CASES ELIMINATING THE ORIGINAL SYSTEM ENTIRELY. THIS IS JUST NOT ACCEPTABLE. AGAIN, THIS "NEW SYSTEM THE BIG THREE ARE PUTTING IN IS FAR WORSE THAT THE OLD, SIMPLY BECAUSE IT HAS NO ROOM FOR FORGIVENESS IN A TRAILER SYSTEM THAT MIGHT WORK OTHERWISE, BUT HAS A SLIGHT DEVIATION IN WHAT IS CONSIDERED "ACCEPTABLE" TO THE CONTROLLER. AT THE VERY LEAST, THERE SHOULD BE A FAIL SAFE METHOD.

HEADLIGHT PERFORMANCE IS VERY POOR WITH WEAK YELLOW BEAM BOTH ON LOW AND HIGH BEAMS. DIFFICULTY SEEING DURING NIGHT DRIVING, ESPECIALLY AT HIGHWAY SPEEDS IN DARK AREAS, IS VERY HAZARDOUS, EVEN WORSE DURING RAIN. I AM CONCERNED ABOUT MY SAFETY AND THAT OF MY FAMILY WHILE DRIVING THIS TRUCK AT NIGHT. THE PROJECTOR-STYLE HEADLAMPS ON THE VEHICLE WERE DIM WITH A YELLOW COLOR AND PROVIDED INADEQUATE FRONT AND SIDE ILLUMINATION. THE HEADLIGHT AIM WAS RAISED, WHICH RESULTED IN LITTLE IMPROVEMENT.

PROJECTOR HEADLIGHTS ON 2015 SIERRA IS VERY DIM COMPARED TO OTHER VEHICLES. TRIED ADJUSTING BUT DID NOT HELP. VERY POOR VISIBILITY IN UNLIT DARK ROADS AND STREETS AND POSES RISK. I TRIED BRINGING IT TO THE DEALER BUT THEY COULD NOT DO ANYTHING ABOUT IT. I MENTIONED SEVERAL COMPLAINTS FROM OTHER OWNERS INCLUDING A CLASS ACTION LAW SUITE THAT WAS FILED IN CALIFORNIA IN OCTOBER 2015. UNFORTUNATELY, THERE ARE NO OTHER ALTERNATIVES WITH THE EXCEPTION OF PURCHASING AFTERMARKET HEADLIGHTS. I WOULD LIKE GMC TO FIX THIS KNOWN PROBLEM. APPARENTLY THEY DID AS THEY CHANGED THE 2016 MODELS' HEADLAMPS AND INCORPORATED HIGHER LUMENS ON LIGHTING, WHY CHANGE IT IF IT WAS NOT A PROBLEM IN THE FIRST PLACE? IT'S VERY DIFFICULT TO SEE PEDESTRIANS AND OBJECTS AT NIGHT.

I PURCHASED THIS VEHICLE NEW AUGUST 2015. THE HEADLIGHT PROJECTION AND ILLUMINATION ON THIS VEHICLE IS EXTREMELY POOR ESPECIALLY DURING WET ROADS OR RAINING CONDITIONS. I HAVE TO USE THE FOG LIGHTS AT ALL TIMES AND STILL DO NOT HAVE ADEQUATE LIGHTING. I FEEL THIS SITUATION CAN AND WILL RESULT IN SERIOUS INJURY OR DEATH DUE TO LACK OF PROPER LIGHTING. I WAS APPALLED TO FIND OUT GENERAL MOTORS ONLY USE A SINGLE HALOGEN BULB INSTEAD OF A DUAL FILAMENT LAMP OR A COMBINATION LOW AND HIGH BEAM LAMPS. I PERSONALLY NEARLY HIT A PEDESTRIAN DURING A RAINY SITUATION, AND ALSO FEEL UNSAFE OPERATING THIS VEHICLE AT DARK.

HEADLIGHT DESIGN IS TERRIBLE. I GET AT BEST 40FT. OF LIGHT PROJECTION ON LOW. WHEN THE HIGH BEAMS ARE ENGAGED I GET NO FURTHER PROJECTION BUT I GET A HIGHER PROJECTION. IT DOES A GREAT JOB LIGHTING THE TOPS OF THE TREES BUT THAT'S ABOUT ALL. UNBELIEVABLE SAFETY HAZARD WHILE DRIVING IN RURAL SOUTHWEST FLORIDA.

THE HEADLIGHTS WITH WHICH THIS VEHICLE ARE EQUIPPED ARE DIM AND UNSAFE. I HAVE OWNED MANY VEHICLES, INCLUDING SEVERAL MADE BY GM, AND THIS ONE IS THE WORST. THE ILLUMINATION OF THE ROADWAY IS INSUFFICIENT TO DISCERN HAZARDS ON/NEAR THE ROADWAY AT NIGHT. THIS IS TRUE AT ANY REASONABLE SPEED AND IS MUCH, MUC HWORSE DURING INCLEMENT WX, PARTICULARLY WHEN RAINING.

THE HEAD LIGHTS ON THIS TRUCK ARE VERY BAD. I SPENT 45,000 DOLLARS ON SOMTHING THAT SHOULD NOT BE A PROBLEM. ON HIGH BEAMS THE DRIVERS SIDE HEAD LIGHT GOES ALMOST STRAIGHT OUT FROM THE TRUCK. ON THE PASSENGERS SIDE THE HIGH BEAM LIGHT GOES OUT TO LEFT . IT 'S LIKE THE RIGHT SIDE LIGHT IS GOING TO MIDDLE OF TRUCK. YOU CAN REALLY SEE IT ON A DARK ROAD WITH ROAD BANKS OR TREES ON BOTH SIDES OF THE ROAD.I TOOK TO DEALER AND THEY CHECKED IT OUT WITH ANOTHER TRUCK. BIG DEAL! THAT TELLS ME THAT BOTH TRUCKS ARE DOING THE SAME THING.( DAHAAA). I CALLED GMC AND FILED A COMPLAINT . THEY CALLED BACK AND SAID THEY TALKED TO THE DEALER AND THEY CAN'T DO ANYTHING ABOUT IT (.DAHAA.)...I HOPE NO ONE ASKS ME ABOUT THESE NEW TRUCKS????? I NEVER THOGHT I WOULD HAVE A TRUCK FROM THE DARKS AGAIN. I WAS WRONG. PLEASE FIX THE PROBLEM GM... THIS IS STUPID... THANKS FOR NOTHING.
