2015 GMC SIERRA Complaints

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

WHEN AT SPEEDS OF ROUGHLY 50MPH SEATS VIBRATE. TRUCK HAS ROUGHLY 3000MILES AND THE FRAME, REAREND AND OTHER UNDERBODY COMPONENTS HAVE ALOT OF SURFACE RUST

HEADLIGHTS ARE FAR TO DIM AND DIRECTIONAL TO DRIVE SAFELY AT NIGHT. HAD THE LIGHT FIX DONE AT DEALER. NOW HORIZONTAL BLACK LINE GOING DOWN HILL MEAN YOU CAN ONLY SEE A VERY SHORT DISTANCE IN FRONT OF YOU? HEADLIGHTS STILL INADEQUATE .

THE HEADLIGHTS ARE VERY DIM AND MAKE IT HARD TO SEE AT NIGHT. I HAVE HAD SEVERAL SITUATIONS WHERE AN ACCIDENT WAS MORE LIKELY DUE TO THE DIM LIGHTING.

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.

MY VEHICLE SHAKES AT HIGHWAY SPEED. I CAN FEEL IT IN THE STEERING WHEEL, AND SEAT. VISUALLY I CAN SEE THE BED OF THE TRUCK SHAKE. THE ISSUE HAS NOT GONE AWAY.

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.
