Air bags, side/window, curtain, inflatorJul 1, 2021
General Motors LLC (GM) is recalling certain 2015-2016 GMC Sierra 1500, 2500, 3500, and Chevrolet Silverado 1500, 2500, and 3500 trucks. The roof-rail air bag (RRAB) inflator end cap may detach from the inflator, or the inflator sidewall may rupture.
A separated inflator end cap or inflator rupture can allow compressed gas to escape, resulting in the end cap or other components being propelled into the vehicle, increasing the risk of injury or crash.
Dealers will replace the left and right side RRAB modules, free of charge. Interim owner notification letters informing owners of the safety risk were mailed on August 18, 2021. Owners will receive a second notice when the remedy is available. Phase I owner notification letters were mailed on May 5, 2022. Phase II owner notification letters are expected to be mailed on May 31, 2022. Owners may contact GMC customer service at 1-888-988-7267 or Chevrolet customer service at 1-800-222-1020.

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.

As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash.

While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. 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.

Suspension, Mar 30, 2016
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, Mar 17, 2016
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, Mar 16, 2016
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.
Other or unspecified, Mar 16, 2016
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.
Exterior lighting, Mar 15, 2016
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, Mar 10, 2016
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.
Exterior lighting, Mar 7, 2016
TL* THE CONTACT OWNS A 2015 GMC SIERRA. WHILE DRIVING AT NIGHT, THE LOW BEAM HEADLIGHTS FAILED TO ILLUMINATE SUFFICIENTLY. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 7,500.
Exterior lighting, Mar 6, 2016
THE LOW BEAMS ONLY ILLUMINATE 40 TO 50 FEET DOWN THE ROAD. THE HIGH BEAMS PROVIDE VERY POOR VISIBILITY. THERE IS ABSOLUTELY NO SIDE ILLUMINATION. THIS IS A CHALLENGING VEHICLE TO DRIVE AT NIGHT.
Exterior lighting, Mar 5, 2016
PROJECTOR-STYLE HEADLAMPS ON 2015 GMC SIERRA PROVIDE INADEQUATE ILLUMINATION-EVEN AFTER MANUFACTURER SERVICE BULLETIN WAS PERFORMED, STILL VERY UNSAFE TO DRIVE AT NIGHT IN AREA WITH NO STREET LIGHTS-LITERALLY NO SIDE ILLUMINATION, AND DISTANCE IN FRONT OF VEHICLE IS NOT ILLUMINATED ADEQUATELY. GMC (GM) CHANGED HEADLAMP DESIGN IN 2016 TO CORRECT THIS, BUT HAS OFFERED NO ASSISTANCE TO OWNERS OF 2014-15 VEHICLES. I'VE HAD SEVERAL CLOSE CALLS WITH DEER AT NIGHT DUE TO SUCH POOR LIGHTING. MY PREVIOUS, 10 YR. OLD TRUCK HAD BETTER HEADLIGHTS! HOPEFULLY SOMETHING CAN BE DONE TO CORRECT THIS ISSUE. COMPLAINED TO DEALER, TO GMC CUSTOMER SERVICE, NOW WHAT? SEEMS THE MANUFACTURER HAS NO PLANS TO HELP. HEADLAMP DESIGN WAS POOR, ONLY USES A SINGLE HALOGEN BULB FOR HIGH & LOW BEAM.
Power train, Mar 1, 2016, crash
DRIVING NORTH ON THE GARDEN STATE PARKWAY IN THE CENTER LANE IT FELT LIKE I HAD A BACK TIRE BLOWOUT BUT WHAT HAPPENED WAS MY REAR AXLE BROKE CAUSING MY VEHICLE TO BE EXTREMELY HARD TO CONTROL. I WAS TRYING TO STEER THE VEHICLE BUT COULD NOT CONTROL THE TRUCK, IT FELT LIKE I HAD LIMITED BRAKING ABILITY, SMASHING INTO GUARDRAIL IT FINALLY CAME TO A STOP.

THE PERFORMANCE OF THE GMC HEADLIGHTS SEEMS TO BE WAY BELOW PAR. THIS TRUCK HAS THE WORST HEADLIGHTS I HAVE EVER OWNED. IN MY OPINION THIS IS A SAFETY HAZARD TO MYSELF AND THE PUBLIC.
Exterior lighting, Feb 23, 2016
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.
Exterior lighting, Feb 12, 2016
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.
Exterior lighting, Feb 11, 2016
THE HEAD LIGHTS ARE INADEQUATE FOR NIGHT DRIVING. BOTH LOW AND HIGH BEAMS DO NOT LIGHT UP ENOUGH AREA IN FRONT OF THE VEHICLE NEARLY AS GOOD AS PREVIOUS MODEL YEARS. THE PROJECTOR STYLE LIGHTS ARE TOO FOCUSED AND DO NOT GIVE ENOUGH LIGHT TO THE SIDES TO SEE ADEQUATELY DOWN THE ROAD. GM IS OBVIOUSLY AWARE OF THE ISSUE AND PERFORMED A BCM UPDATE TO MY VEHICLE TO MAKE THE LIGHTS BRIGHTER BUT THAT FIX STILL DOESN'T RESOLVE THE ISSUE. 2016 MODEL YEARS HAVE A COMPLETELY DIFFERENT HEADLIGHT ALLOWING THOSE TRUCKS TO SEE MUCH BETTER AT NIGHT WHICH TELLS ME THEY ARE AWARE OF THE LIGHTING ISSUES AND FIXED IT FOR THE 2016 GM TRUCKS.
Exterior lighting, Feb 11, 2016
MY 2015 GMC SIERRA'S HEADLIGHTS PROVIDE HORRIBLE VISIBILITY AT NIGHT, THE OEM PROJECTOR STYLE HEADLIGHTS INSTALLED IN THIS TRUCK ARE DIM, WEAK AND UNSAFE. I BROUGHT MY SIERRA BACK TO THE DEALERSHIP AND THEY APPLIED TSB #PIT5374 AND UPGRADED THE HEADLIGHTS WITH THE VOLSA HIR BULBS. THIS UPGRADE PROVIDED A NOMINAL INCREASE IN BRIGHTNESS, BUT THE HEADLIGHTS ARE STILL DIM AND UNSAFE FOR USE WHILE DRIVING ON DARK ROADS OR IN THE RAIN. THE DO NOT PROVIDE ANY ILLUMINATION ON THE SIDE OF THE ROADS, ESPECIALLY ON DARK COUNTRY ROADS WHICH MAKES IT HARD TO SEE WILDLIFE AND OTHER POTENTIAL HAZARDS. THE DESIGN OF THE HEADLIGHTS ON THE 2014/2015 GMC SIERRA ARE SEVERELY DEFICIENT. IT IS MY UNDERSTANDING THAT GMC IS FULLY AWARE OF THIS PROBLEM, SO MUCH SO THAT THEY REDESIGNED THE HEADLIGHTS ON THE 2016 GMC SIERRA WHICH HAS THE SIGNIFICANTLY BETTER HID HEADLIGHTS. I HAVE ALREADY LOGGED A COMPLAINT AND SPOKE WITH REPRESENTATIVES FROM GMC WHO LOOKED INTO MY ISSUE AND THE END RESULT WAS THAT THERE WAS NOTHING ELSE THEY COULD DO.
Exterior lighting, Feb 10, 2016
THE HI/LOW BEAM HEADLIGHTS ARE NOT USEABLE IN ANYTHING THAN CLEAR DRY WELL MARK ROADS. CAN NOT SEE THE SIDE ROAD TO TURN ON IT. IF I HAD KNOW THEY WERE THIS BAD WOULD NOT HAVE BOUGHT THIS TRUCK.

TL* THE CONTACT OWNS A 2015 GMC SIERRA. WHILE DRIVING APPROXIMATELY 60 MPH, THE VEHICLE BEGAN TO VIBRATE. THE LONGER THE VEHICLE WAS DRIVEN, THE MORE IT SHOOK. THE CONTACT TOOK THE VEHICLE TO THE DEALER SEVERAL TIMES, BUT NO FAILURE WAS FOUND. THE DEALER TEST DROVE THE VEHICLE AND IT DID NOT VIBRATE. THE DEALER REPLACED THE TIRES, TRANSMISSION, AND SHOCKS; HOWEVER,, THE FAILURE RECURRED. THE VEHICLE WAS NOT REPAIRED. THE CONTACT STATED THE SEAT WARMERS ALSO FAILED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURES. THE APPROXIMATE FAILURE MILEAGE WAS 2,500.
Exterior lighting, Feb 1, 2016
HEADLIGHTS ARE EXTREMELY DIM. HIGH BEAMS PROVIDE NO ILLUMINATION TO THE FRONT SIDES OF THE VEHICLE. USING FOG LIGHTS WITH LOW BEAM IS ACTUALLY BRIGHTER THAN THE HIGH BEAMS. EVEN AFTER HAVING THE DEALER INSTALL NEW BULBS THE LIGHTING IS VERY WEAK IN A LOW ILLUMINATION AREA, I.E. NO MOON, NO STREET LIGHT, ROAD. WHEN MAKING A TURN IN AN UN LIT AREA I CAN'T EVEN SEE WHERE THE SIDE OF THE ROAD ENDS. THESE SO CALLED PROJECTOR TYPE HEADLIGHTS DON'T SEEM TO WORK VERY WELL. I KNOW FOR A FACT THE 2014 AND 2015 HAVE THE SAME SET UP. THE 2016 HAS A WHOLE NEW SET UP WITH HID LIGHTING AND WORK GREAT. THIS TELLS ME THAT GM KNOWS THERE IS A PROBLEM. UNFORTUNATELY THEIR "FIX" ONLY IF YOU COMPLAIN, ISN'T FIXING ANYTHING... ON A TRIP IN THE SMOKEY MOUNTAINS IN GATLINBURG TN I NEARLY CRASHED OFF THE SIDE OF THE MOUNTAIN. I COULD NOT SEE WHERE THE EDGE OF THE ROAD WAS. EVEN THE PASSENGERS ASKED ME "WHAT IS WRONG WITH YOUR LIGHTS?" THE SAID "TURN ON YOUR HIGH BEAMS" AND I STATED, "THEY ARE ON". WE CAN'T BELIEVE THESE LIGHT PASS THE COMMON SENSE TEST..

ON TWO SEPARATE OCCASIONS MY TRUCK HAS ACTED LIKE IT IS IN NEUTRAL WHILE DRIVING. THE DRIVE SYSTEM DISENGAGES AND THE ENGINE JUST REVS.

90% OF MY DRIVING IS AT NIGHT. I DRIVE ON MIXED ROADWAYS. I FIND THAT THE HEADLAMPS ON MY GMC SIERRA ARE INADEQUATE AT BEST. I BROUGHT THE SIERRA TO THE DEALER, WHO PERFORMED A TSB, AND ALTHOUGH IT IMPROVED THE LIGHTING, IT IS STILL WAY BELOW PAR. IT'S AS IF I'M DRIVING A 20 YEAR OLD CAR WITH YELLOWED OUT LENS COVER. IN RAINY WEATHER, THE HEADLAMPS ARE NONEXISTENT.

THE HEADLIGHTS ON MY VEHICLE ARE UNSAFE FOR NIGHT DRIVING IN UNFAMILIAR ROADWAYS. BESIDES BEING VERY DIM, ANYTHING 60-70 FEET AHEAD OF YOU CAN'T BE SEEN. THERE IS A CUTOFF LINE THAT BLOCKS ROADSIDE OBJECTS AND THE CUTOFF TOP BAR THAT DOESN'T ILLUMINATE ROAD SIGNS OR STREET MARKERS. IMAGINE HOLDING A SHOE BOX TO YOUR FACE WITH BOTH END REMOVED AND THAT DESCRIBES DRIVING WITH THIS UNSAFE SYSTEM. I THOUGHT MINE WAY AN ISOLATED CASE BUT "PROBLEMS WITH GMC HEADLIGHTS" ON THE INTERNET CLEARLY SHOWS A MAJOR PROBLEM THAT NEEDS TO BE RECALLED AND REPLACED.
