Seat belts, frontApr 8, 2021
General Motors, LLC (GM) is recalling certain 2014-2016 Chevrolet Silverado 1500, 2015-2016 Chevrolet Tahoe, and 2014-2015 GMC Sierra 1500 vehicles that may have received an incorrect replacement tensioner cable assembly as part of a previous recall remedy or a subsequent repair. The flexible steel cable connecting the driver's seat belt to the outboard side of the seat may be repeatedly bent over the seat side shield as the driver enters and exits the vehicle causing the cable to fatigue and separate.
A broken pretensioner cable reduces the effectiveness of the driver's seat belt, increasing the risk of injury.
GM will notify owners, and dealers will replace the driver seat belt lap pretensioner, free of charge. The recall began on May 5, 2021. Owners may contact Chevrolet customer service at 1-800-222-1020, and GMC customer service at 1-800-462-8782. GM's number for this recall is N212330040.

Service brakes, hydraulic, antilock/traction control/electronic limited slip, wheel speed sensor/tone ringOct 24, 2019
General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.
Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.
GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.

During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.
A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.
GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on August 4, 2017.

THE HEADLIGHTS ON THIS TRUCK ARE HORRIBLE. I CAN BARELY SEE THE ROAD OR SIDES OF THE ROAD. AT NIGHT CARS BEHIND/BESIDE ME FLOOD OUT MY LIGHTS. I HAVE THE INTERIOR LIGHTS TURNED COMPLETELY DOWN AND STILL THE LIGHTS ARE VERY WEAK AND DANGEROUS. *TR
Exterior lighting, Feb 8, 2015
THE FACTORY HEADLIGHTS ARE ALMOST USELESS AT NIGHT ESPECIALLY IF THERE IS ANY MOISTURE ON THE ROADS . THEY ARE ABSOLUTELY HORRIBLE AT DUSK AND DAWN AS WELL . *JS
Exterior lighting, Feb 7, 2015
THE LARGE 8" INTELLILINK RADIO SCREEN IN THIS TRUCK HAS SEPARATE BRIGHTNESS CONTROL FROM THE REST OF THE DASH LIGHTS, INCLUDING THE INSTRUMENT PANEL. DUE TO IT'S SIZE AND COLORED BACKGROUND, THE LCD RADIO SCREEN IS MUCH BRIGHTER THAN THE REST OF THE INTERIOR LIGHTS. THE FACT THAT THE SYSTEM HAS NO NIGHT SCHEME, MEANING IT DOESN'T SHIFT TO A MOSTLY BLACK BACKGROUND AT NIGHT MAKES THIS PROBLEM EVEN WORSE. WHILE IT IS POSSIBLE TO LOWER THE BRIGHTNESS USING A DASH-MOUNTED DIMMER SWITCH, THE DIMMER MUST BE LOWERED TO MINIMUM IN ORDER TO GET THE RADIO SCREEN TO BE A COMFORTABLE BRIGHTNESS LEVEL FOR NIGHT DRIVING. AT THIS POINT, THE INSTRUMENT CLUSTER LIGHTS ARE SO DIM AS TO BE EXTREMELY DIFFICULT TO SEE AND AS A RESULT REQUIRE MUCH MORE TIME AND EFFORT TO READ SPEED INFORMATION. THE ONLY WAY TO COMPLETELY TURN OFF THE RADIO SCREEN IS TO GO THROUGH SEVERAL MENUS INTO SETTINGS AND MANUALLY TURN OFF THE SCREEN. NOT ONLY IS THIS A DANGEROUS DISTRACTION WHILE DRIVING BUT IF ANY VEHICLE SETTING SUCH AS RADIO VOLUME, OR HVAC CONTROLS ARE ADJUSTED, THE SCREEN AUTOMATICALLY TURNS BACK ON AND THE PROCESS MUST BE REPEATED. I HAVE CONTACTED GM SEVERAL TIMES ABOUT THIS ISSUE DUE TO ITS DISTRACTING NATURE WHEN DRIVING AT NIGHT AND HAVE BEEN TOLD REPEATEDLY THAT THE SYSTEM IS "OPERATING AS DESIGNED." I FEEL THIS IS A SAFETY ISSUE SINCE THE BRIGHT LIGHT IN THE CAB RUINS NIGHT VISION WHILE ALSO DISTRACTING THE DRIVER'S EYES FROM THE ROAD. MY RECOMMENDATION IS FOR A SOFTWARE UPDATE FOR THE INTELLILINK/RADIO SYSTEM TO BE DESIGNED TO ADD A BRIGHTNESS SETTING IN THE SYSTEM MENU TO ALLOW DRIVER'S TO SET THE RADIO SCREEN BRIGHTNESS INDEPENDENTLY OF THE INSTRUMENT CLUSTER LIGHTS AND TO ALSO PROGRAM A "NIGHT MODE" COLOR SCHEME THAT WOULD SHIFT FROM THE BLUE ILLUMINATED BACKGROUND USED IN THE DAYTIME TO SOMETHING THAT IS MOSTLY BLACK. *JS
Exterior lighting, Feb 7, 2015
THE PROJECTOR STYLE HEADLIGHTS THIS TRUCK IS EQUIPPED WITH ARE INSUFFICIENT FOR SAFE NIGHT DRIVING WHEN NOT IN A CITY DRIVING CONDITION. THE LOW-BEAMS ARE SATISFACTORY FOR LOWER SPEEDS (IE <45MPH) BUT ARE EXTREMELY EASY TO OUT-DRIVE AT HIGHWAY SPEEDS. THE BEAM PATTERN IS ALSO NOT WIDE ENOUGH TO ILLUMINATE ANYTHING OTHER THAN THE AREA DIRECTLY IN FRONT OF THE VEHICLE. THE HIGH BEAMS ARE EVEN WORSE. THE HEADLIGHTS IN THIS TRUCK USE ONE SINGLE FILAMENT BULB FOR EACH HEADLIGHT. WHEN THE HIGH BEAMS ARE TURNED ON, A MECHANICAL SHUTTER OPENS TO ALLOW MORE LIGHT THROUGH THE PROJECTOR LENS. THE LENS IS DESIGNED SUCH THAT THIS ADDITIONAL LIGHT IS AIMED SO HIGH AS TO BE USELESS. PARKED 20FT FROM A WALL, THE CENTER OF THE HIGH BEAM PATTER IS ALREADY SEVERAL FT ABOVE THE BULB LEVEL ON THE WALL. WHEN DRIVING ON A STRAIGHT AND LEVEL ROAD WITH NO TREES, IT IS ACTUALLY IMPOSSIBLE TO EVEN TELL THE HIGH BEAMS ARE ON SINCE THERE IS NO EXTRA BEAM TO ILLUMINATE THE SIDES OF THE ROAD AND THE CENTER BEAM IS POINTED UP INTO THE TREES. *JS
Exterior lighting, Feb 6, 2015
HEADLIGHTS DO NOT PROVIDE ADEQUATE ILLUMINATION FOR NIGHT DRIVING. SHOULD BE CONSIDERED A SAFETY HAZARD TO OCCUPANTS AND OTHERS ON THE ROAD. POOR DESIGN AND/OR SPECIFICATIONS ON GM'S PART TO ALLOW THE USAGE OF THIS HEADLAMP CONFIGURATION ON ANY VEHICLE ON THE ROAD TODAY. THIS ISSUE NEEDS TO BE ADDRESSED AND RESOLVED ASAP. *JS

ON 12/12/14, MY HUSBAND CAME HOME AT APPROXIMATELY 2:00 PM AND APPROXIMATELY AN HOUR THE GARAGE WAS ON FIRE AND FIRE APPEARS TO HAVE STARTED IN THE TRUCK. GM CAME OUT AND INVESTIGATED WITH USAA BUT SINCE THERE IS NOTHING LEFT OF THE TRUCK THE CAUSE IS UNDETERMINED. THE ENTIRE HOUSE IS A TOTAL LOSS. THERE IS NO ROOF LEFT TO TRUCK. GM TRYING TO BLAME ON A REFRIDGERATOR CORD OR CORD IN WORKSHOP OR SPRINKLING SYSTEM. *JS

THIS IS MY FIRST TIME TO HAVE A VEHICLE WITH PROJECTOR HEADLIGHTS. THEY DO NOT LIGHT UP THE SIDES OF ROAD, AND ARE NOT VERY BRIGHT IN DIM OR HIGH BEAM. THIS IS NOT VERY SAFE WHEN DRIVING AT NIGHT, EVEN WHEN THE WEATHER IS GOOD. I WILL NOT BUY ANOTHER VEHICLE WITH THESE TYPE OF HEADLIGHTS. *TR

THESE ARE THE WORST HEADLIGHTS. I LIVE IN RURAL ALABAMA AND CANT SEE EDGES OF ROAD OR MORE THAN 50' AHEAD. CANT CHANGE THE BULB TO IMPROVE IT. VERY DANGEROUS AT NIGHT FOR ME AND ANYONE ELSE ON THE ROAD! *TR
Exterior lighting, Jan 29, 2015
WHEN I FIRST STARTED DRIVING MY NEW 14 GMC I HAD NEVER HAD A TRUCK WITH PROJECTOR HEADLIGHTS SO I WAS UNSURE IF IT WAS JUST ME THAT HAD TO ADJUST TO THE BEAM OF LIGHT THEY PROVIDE OR IF IT WAS A PROBLEM WITH THE LIGHTING ITSELF. AFTER HAVING DRIVEN MY 14 SILEVRADO WORK TRUCK WITH STANDARD LIGHTS I REALIZE THERE IS A HUGE PROBLEM WITH THE GMC PROJECTOR LIGHTS THEY ARE SO BAD IT MAKES YOU THINK THERE IS A FAULTY GROUND WIRE OR SOMETHING EXTRA ORDINARY WRONG WITH THE HEADLIGHTS. IT IS SO BAD THAT I EVEN LOOKED INTO UPGRADING THE BULBS BUT YOU CAN'T EVEN DO THAT BECAUSE PHILIPS OWNS THE RIGHTS TO PRODUCE THEM AND WANTS TO OVER CHARGE THE AFTERMARKET FOR THE USE OF THE DESIGN, SO I AM STUCK WITH A HEADLIGHT SYSTEM THAT IS WORSE THEN A 6V HEADLIGHT FROM THE 40S. *TR

THE PART BROKE IN HALF AT LOW SPEED WHILE I WAS DRIVING IN A CONSTRUCTION AREA (MY OWN DRIVEWAY BEING INSTALLED) I HIT SOMETHING AND THE METAL CASING OF THE AXLE WHERE IT ATTACHES TO THE FRONT DIFF. BROKE IN HALF. I AM 60 YEARS OLD MY WIFE WAS IN THE TRUCK I WAS GOING SO SLOW THE SPEEDOMETER WAS ON 0. THE DEALER SAID THE PART WAS CRACKED BY THE IMPACT. THIS IS SUPPOSED TO BE A HEAVY DUTY 4X4 P/U, IF I WAS GOING AT 40 MPH OFF ROAD WHAT WOULD HAVE BROKE AND WHAT WOULD HAVE BEEN THE RESULT? I THINK THE METAL OF THE CASING WAS FLAWED AND I AM AFRAID TO KEEP THE TRUCK. THE DEALER SAID THIS ISN'T A WARRANTY ISSUE I HAD TO PUT A CLAIM INTO MY INS. THIS IS NOT ONLY A CONCERN FOR SAFETY BUT FOR FINANCES AS WELL. I PAID $44,000. CASH FOR THIS TRUCK, IT IS THE SIERRA SLT NOT ONLY A 4X4 BUT IT HAS 20" RIMS FOR ADDED HEIGHT. THIS WAS NOT HIT HARD ENOUGH TO CRACK A STEEL CASING. THE TRUCK IS AT A GMC/BUICK DEALER IN MOUNT DORA FL. THEY SAID IT MIGHT TAKE AWHILE TO FIND THE PARTS TO FIX IT. I DO NOT THINK GMC MAKES CHEAP TRUCKS OR DANGEROUS TRUCKS BUT I THINK AFTER THIS GETS FIXED I WILL BE LOOKING INTO TRADING IT. *TR

THE HEADLIGHTS DO NOT ADEQUATELY ILLUMINATE THE ROAD. THERE IS NO LIGHT TO THE SIDE OF ROAD. I CAME VERY CLOSE TO DRIVING INTO A DITCH. WHEN DRIVING DOWN OR UP GRADES THE ROAD IS IN COMPLETE DARKNESS. NO DISCERNIBLE DIFFERENCE BETWEEN HIGH AND LOW BEAMS. IT'S VERY DANGEROUS DRIVING ON UNLIT COUNTRY ROADS NEAR MY HOME IN UPSTATE NY. WHEN RAINING THE PROBLEM IS EVEN WORSE. THE HEADLAMPS ON ALL 4 OF MY PREVIOUS GM TRUCKS 9JIMMYS, YUKON AND SUBURBAN) WERE FAR SUPERIOR TO THOSE ON MY NEW $55,000 SIERRA. THIS TRUCK SHOULD NOT BE DRIVEN AT NIGHT BUT THAT'S UNAVOIDABLE, SOMEONE'S GOING TO BE HURT OR KILLED!!! *TR

MY COMPLAINT IS WITH THE HOW DIM THE OEM HEADLIGHTS ARE. I HAVE COMPLAINED TO GMC REGARDING THE HEADLIGHTS AND THE RESPONSE IS THAT THEY ARE OK WITH HOW DIM THE LIGHTS ARE. COMPARED TO OTHER VEHICLES I OWN/HAVE OWNED THE HEADLIGHTS ARE EXTREMELY DIM TO THE POINT OF BEING DANGEROUS. *TR

THE TRUCK WAS AVERAGING ABOUT 20 MPG BUT SHIFTING ERRATICALLY LIKE IT COULDN'T DECIDE WHAT GEAR TO BE IN. AFTER USING THE 4WD THE FIRST TIME THE MPG DROPPED OFF TO ABOUT 17 AND HAS BEEN DECLINING STEADILY CURRENTLY I GET 14 TO 15 MPG AND DRIVE 150 MILES PER DAY MOSTLY HIGHWAY. I HAVE TAKEN IT BACK TO THE DEALER TWICE THEY SAID THE COMPUTER COULDN'T GET USED TO MY DRIVING STYLE AND REPROGRAMMED THE COMPUTER. WHEN I TOOK IT BACK ABOUT THE MILEAGE A GUY CAME OUT AND SAID HE COULD TELL IF SOMETHING WAS STUCK AND SWITCHED THE 4WD A FEW TIME AND SAID IT WAS FINE. MY MPG IS GETTING WORSE AND IT SLAMS IN AND OUT OF GEAR 2-3 TIMES IN A MATTER OF SECONDS WHILE SUSTAINING A STEADY HIGHWAY SPEED ON A FLAT SURFACE. *TR

THE HEADLAMPS ARE TOTALLY INADEQUATE FOR NIGHT DRIVING THUS PRODUCING A VERY SIGNIFICANT SAFETY ISSUE . THERE IS ZERO LIGHTING ON BOTH SIDES ON LOW BEAM AND VERY POOR DOWN ROAD VISION ON HIGHBEAM. THERE ARE MANY COMPLAINTS ON LINE AND THEY ARE ALL WITH THE SAME ISSUES. IT HAS TO DO WITH THE CHEAP ONE BULB LENS SYSTEM WITH A SHUTTER ON THE LENS. HAVE COMPLAINED TO DEALER WHO ACKNOWLEDGED THERE IS A PROBLEM AND TO GM WHO REFUSES TO ACKNOWLEDGE THERE IS A PROBLEM . GM RESPONSE TO ME WAS THE LAMPS WORK AS DESIGNED AND I RESPONDED THAT IS EXACTLY THE PROBLEM, THE DESIGN WHICH PRODUCES VERY DANGEROUS DRIVING CONDITIONS. *TR

THE HEADLIGHTS ON THIS $50K TRUCK ARE JUST PLAIN UNACCEPTABLE! FINALLY TOOK IN TO THE DEALER AS THE BRIGHTS WERE "RACCOON HUNTING" BUT THE DIM SETTING IS ALMOST NO LIGHT AT ALL. LIVING IN A RURAL AREA, I HAVE TO DECREASE MY SPEED TO NEARLY A CRAWL IN ORDER TO WATCH FOR OBSTACLES IN THE ROADWAY OR FOR WILDLIFE. I'VE OWNED 6 GMC VEHICLES (SIERRA OR YUKON) SINCE 2000 AND NONE OF THEM HAD THE POOR AND DANGEROUS LIGHTING THAT THIS 2014 SIERRA HAS. WHEN THE DEALER ADJUSTED, THE DIMS ARE NOW POINTING DOWN TO THE ROAD ABOUT 30' FROM THE BUMPER AND THE HIGH BEAMS ARE BOTH POINTING AT THE MIDDLE OF THE ROAD ABOUT 75-100' WITH NO LATERAL LIGHTING AT ALL. IT'S SO BAD, I HAVE TO MAKE WIDE TURNS TO LIGHT UP THE DRIVEWAYS OR STREETS I'M TURNING INTO TO KEEP FROM RUNNING INTO DITCHES OR MISS THE TURN ALL TOGETHER. ON A 55MPH STRAIGHT ROAD, YOU CAN OUT RUN YOU LIGHTS! THE FOGS HELP THE LATERAL VISION A TINY BIT BUT THEY ARE NOT ALL THAT GOOD EITHER. GMC NEEDS TO ADDRESS THIS OR RISK PAYING OUT ON A BIG LAWSUIT OVER SOMEONE GETTING BADLY INJURED OR WORSE. *TR

MY VEHICLE STARTED WITH A VIBRATION ON OR AROUND 12,000 MILES. THE VIBRATION SLOWLY INCREASED AS TIME WENT ON. I MADE APPOINTMENT WITH THE DEALERSHIP WHERE THE VEHICLE WAS PURCHASED.(CAPITALAND MOTORS) AT THIS TIME THE VIBRATION WAS STRONG ENOUGH TO VIBRATE THE BACK WINDOW. IT WOULD START AT 30MPH AND GET WORSE AT 45MPH. THE MECHANIC CHECKED BALANCE AND ROAD FORCE THE TIRES. BUT TOLD ME THAT THE VIBRATION WAS NORMAL AND HE COULD FIX MY BACK WINDOW. I CALLED GMC AND FILED A COMPLAINT. THEY TOLD ME TO TAKE IT TO ANOTHER DEALERSHIP. I DID ON 11/25/14. THIS TIME I TOOK IT TO GOLDSTEIN BUICK-GMC. THEY COULD FEEL THE VIBRATION IN THE STEERING WHEEL AND SEAT. THEY CHECK TIRES AGAIN. THEY FELT IT WAS THE TIRES AND WANTED ME TO BUY NEW ONES. TOLD ME THE TIRES WERE NOT UNDER WARRANTY. THAT DAY I CALLED GOODYEAR AND FOUND OUT MY TIRES WERE UNDER WARRANTY, THEY WOULD BE PRORATED. GOODYEAR CHECK MY TIRES AND THEY ARE FINE. AT THIS TIME NO ONE CAN FIND THE PROBLEM AND I FEEL IT HAS BECOME A SAFETY ISSUE. THE VIBRATION IS REALLY STRONG AND GETTING WORSE AND THEY HAVE NO ANSWER. *TR
