AIR BAGS
WHILE DRIVING STRAIGHT/UPSLOPE ON A DIRT ROAD THE SIDE AIR BAGS DEPLOYED IN MY 2015 SIERRA 2500 HD PICKUP TRUCK. THERE WAS NO IMPACT AND ABSOLUTELY NO DAMAGE TO THE EXTERIOR OR UNDERCARRIAGE OF THE VEHICLE. VEHICLE WOULD NOT RESTART FOR SEVERAL MINUTES AFTER THE AIR BAG DEPLOYMENT (IF ON A BUSY STREET I WOULD HAVE BEEN UNABLE TO GET OUT OF ROADWAY)

EXTERIOR LIGHTING
THE ILLUMINATION PERFORMANCE OF THE HEADLIGHTS ON MY 2015 GMC SIERRA IS UNSATISFACTORY FOR DRIVING ON RURAL ROADS. THE PERFORMANCE IS ALSO SUBPAR IN FOGGY AND WET CONDITIONS. I FEEL THAT I AM UNABLE TO DRIVE SAFELY AT THE POSTED HIGHWAY SPEEDS USING THE CURRENT HEADLIGHTS PROVIDED BY THE AUTOMAKER. I FEEL THAT IT IS A SAFETY HAZARD AND COULD POSSIBLY CONTRIBUTE TO HAZARDOUS DRIVING SITUATIONS AT NIGHT. I ALSO FEEL THAT IT COULD CAUSE A POTENTIAL ACCIDENT DUE TO THE POOR VISIBILITY AT POSTED HIGHWAY SPEEDS.

POWER TRAIN, UNKNOWN OR OTHER
BROUGHT IN MY 2015 GMC 1500 SIERRA TRUCK IN FOR VIBRATIONS ISSUES AT HIGH SPEED OF 70-75 MPH. AFTER 4 ATTEMPTS GMC CORP REFUSES TO ADMIT THAT THERE IS A SAFETY ISSUES IN DRIVING THIS VEHICLE AT A NORMAL RATE. THEY CONTINUE TO REMOVE AND REPLACE THE TIRES. I HAVE NEVER OWNED A VEHICLE BEFORE THAT SUCH VIBRATION IS FELT IN THE CABIN OF THE TRUCK, PASSENGER SEAT, FOOT PETAL, ETC.THAT IS SO UNCOMFORTABLE, THAT MY WIFE REFUSE TO DRIVE IN THE TRUCK DUE TO ITS SAFETY. GMC WILL NOT ACKNOWLEDGE ANY OF THESE COMPLAINTS BUT WILL SAY EVERYTHING IS OF SPECS. LIKE OTHERS THIS IS THE WORSE VEHICLE I HAVE EVER PURCHASED. FOUND MORE COMPLAINTS LIKE THIS HAS BEEN FILED, BUT SAME RESULT, GMC WILL DO NOTHING.

EXTERIOR LIGHTING
THE PROJECTOR HEADLIGHTS ARE INADEQUATE ON A LEVEL ROAD, AND ARE DANGEROUS ON ROLLING TERRAIN ROADS AND CURVES. 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.

EXTERIOR LIGHTING
TL* THE CONTACT OWNS A 2015 GMC SIERRA. THE CONTACT STATED THAT THE LOW BEAM HEADLIGHT WAS DEFECTIVE AND DID NOT PROVIDE ADEQUATE LIGHT COVERAGE. THE CONTACT HAD TO ENGAGE THE HIGH BEAMS. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE DEALER RAISED THE LOW BEAMS; HOWEVER; THE LIGHT COVERAGE WAS NOT CORRECTED. THE FAILURE MILEAGE WAS 300. ..UPDATED 05/09/16 *BF THE CONSUMER STATED RIGHT AFTER HE PURCHASED THE VEHICLE, HE NOTICED WHEN DRIVING AT NIGHT, WITH THE LOW BEAMS ON, HIS VISIBILITY WAS APPROXIMATELY 30 FEET TO THE FRONT AND SIDE OF THE VEHICLE. WHEN THE HIGH BEAMS WERE ON, HE WAS ABLE TO SEE AHEAD OF HIM, BUT THE VIEW WAS STILL LIMITED TO ONLY 30 FEET. UPDATED 05/16/16.*JB

EXTERIOR LIGHTING
THE HEADLIGHTS ON THIS TRUCK ARE SO POOR, WE HATE DRIVING IT AT NIGHT! I HAVE TAKEN IT TO THE DEALERSHIP, AND THEY DID AN "UPGRADE" OF DIFFERENT BULBS AND CHANGED THE VOLTAGE. THIS WAS OF LITTLE HELP. NOW, ONE OF THE UPGRADED BULBS HAS ALREADY GONE OUT OF MY LESS THAN ONE YEAR OLD TRUCK.

SERVICE BRAKES
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.

SUSPENSION
TL* THE CONTACT OWNS A 2015 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE DRIVING AT 60 MPH, THERE WAS AN ABNORMAL VIBRATION IN THE CABIN OF THE VEHICLE. THE VEHICLE WAS TAKEN TO A DEALER TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE REAR SUSPENSION NEEDED TO BE REPLACED AND THE TIRE NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED HOWEVER, THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 4,200. THE VIN WAS NOT AVAILABLE.

EXTERIOR LIGHTING
THE HEADLIGHTS ARE NOT SUFFICENT. NIGHT DRIVING IS TERRIBLE, CAN NOT SEE ROAD. I HAVE SPOKEN TO GM SEVERAL TIMES. THEY CAME OUT WITH AN UP DATE, SAYING NEW BULBS AND REPOWER CONTROL MODULE, BUT THEY ARE STILL HORRIBLE. GM HAD THESE LIGHTS FOR TWO YEARS ON THE NEW BODY STYLE FOR THE SIERRA LINE, AND NOW HAVE SWITCHED TO LED HID'S. SO THE PEOPLE WHO OWN 2014 AND 2015 TRUCKS ARE STUCK.

EXTERIOR LIGHTING
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.

EXTERIOR LIGHTING
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.

EXTERIOR LIGHTING
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.

EXTERIOR LIGHTING
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.
