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.

General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time.
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.

Headlights on this vehicle, since purchased, have not cast enough light in order to see in unlit backroads, or extrememly dim areas. I have to drive with my brights on constantly, in order to get enough light thrown onto the road, for the left and right sides, as well as the front. These were not working well since purchase. I took my child to a friends house in rural PA, and I literally could NOT SEE THE street signs, let alone far enough down the road. I nearly hit a stone wall.. My eyes keep asking to see more, but truck does not produce enough headlight. I even went to the eye doctor, after that situation, thinking it was my vision dimming, but was told I have 20/20. There needs to be a formal recall. I am not the only one complaining about these HORRIBLE projection headlights. To replace these headlights would cost over 1000K, out of pocket, which is not something I should have to fix. I am complaining now, because with the light getting darker earlier, am noticing how lousy driving at night really is.. and honestly, being BLINDED by oncoming LED's , without having proper headlights on my truck in order to see when blinded, really [XXX]. Please address these [XXX]. Make headlights great again! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Exterior lighting, Feb 24, 2025
Lack of illumination of headlights straight ahead. No light shines to the sides of the vehicle making it difficult to see left or right when negotiating a turn at night. I have put new bulbs in both sides the best money can buy at CarQuest with no improvement. The headlight lenses are not dirty or fogged over. It appears to be a design problem, and I have seen other people with this model truck complain about the same thing on some blogs. I contacted GM directly looking for information I can get on a possible upgrade, and they have offered not solution. I have had this issue with this vehicle since buying it used 4.28.2018
Exterior lighting, Oct 17, 2023
Headlights are so dim because of the plastic cover that is made into the OEM headlight assembly. The plastic apparently had no UV protectant and the plastic has turned dingey yellow and clouded where it's affected the light output from the vehicle
Exterior lighting, Jun 3, 2023
Lights are too dim to drive at night. Bulbs have been replaced with 6 different styles but the lights are too dim. Bright lights shine too high to be useful. Spoke with numerous people who have had the same problem.
Exterior lighting, Mar 22, 2023
The stock headlights both low and high beams provide poor lighting at night. The headlights provide a poor beam pattern making it incredibly difficult to see more than 100 ft in front of you while driving down dark roads. And even more difficult in light storm conditions both rain and snow. The high beams aim too high when used and don't show enough of the road in front of you but rather the tops of tree's or other objects instead of the road. The low beams don't provide much light on the sides of the road as well and at times feel more like they're just fog lights with the amount of light that is put out. These incidents happen anywhere from low speeds up to highway speeds. I have noticed this issue since purchasing it used and have seen multiple similar complaints online.
Exterior lighting, Jan 30, 2023
This vehicle has poor headlight performance. I changed the bulbs to no avail. There is no way this 2015 GMC passes vehicle state inspections if they really look. There is very little power to the lights, even on the high-beams. After some quick research - GM has a service bulletin PIT5374 that addresses this very issue. But the dealerships are using this safety defect as a way to generate service volume. Requiring a $170.00 diagnosis to identify a problem they already know exists.

The headlights are very poor. Can hardly see at night. They're no better when on high beams.

The contact owns a 2015 GMC Sierra 1500. The contact stated that while driving at various speeds, the transmission failed to operate as designed causing the vehicle to sputter and not properly accelerate. Also, the digital speedometer display would not display properly due to a faulty radio. Additionally, the driver’s side headlight failed to properly illuminate due to moisture build-up inside the headlight assembly. The vehicle was taken to the local dealer who was unable to duplicate the failure. There was no service performed on the vehicle. The manufacturer was not notified of the failure. The approximate failure mileage was 1,000.

THE HEADLAMPS ON MY VEHICLE HAVE BEEN VERY POOR, BOTH IN LOW AND HIGH BEAM POSITIONS EVER SINCE I PURCHASED THE VEHICLE. THINKING THAT THEIR MUST BE SOMETHING WRONG WITH THE EXISTING HEADLAMPS, I PURCHASED THE REPLACEMENT BULBS AND THERE WERE NO IMPROVEMENTS. WHEN DRIVING AT NIGHT I HAVE TO STAY ON LOW BEAM WITH THE FOG LIGHTS ON JUST TO HELP TO SEE. I CAN'T USE MY HIGH BEAMS AT ALL BECAUSE THE LIGHTING IS SO POOR. GMC IS AWARE OF THEIR HEADLAMP ISSUES ON THE 2014 AND 15 MODELS BUT NOTHING IS BEING DONE ABOUT IT TO MY KNOWLEDGE. WITHOUT SPENDING $500-$1000 TO CHANGE THEM OVER TO LED, IS THERE ANYTHING THAT I CAN DO TO IMPROVE THIS SITUATION?

THE 3RD BRAKE LIGHT ALLOWED RAIN TO ENTER THE CAB OF TRUCK.(GASKET FAILED) HEADLINER, CARPET ON FLOOR, INSULATION ALL RUINED. DIAGNOSED BY A "WATER DOCTOR" AT THE DEALER WHERE TRUCK WAS PURCHASED. THE FLOOR ON THE PASSENGER FRONT WAS SOAKED, HEADLINER IS STAINED. I REMOVED ALL SEATS, CARPET, INSULATION AND THE SMELL IS STILL THERE. CALLED GMC TO TRY TO GET ASSISTANCE ON REPAIRS. TRUCK IS OUT OF FACTORY WARRANTY. GMC OFFERED $585 LEAVING A BALANCE OF $1300 TO BE PAID BY ME TO REPLACE THE HEADLINER. HOW IS IT THAT THE 3RD BRAKE LIGHT ALLOWS RAIN TO ENTER THE CAB OF THE VEHICLE. ITEMIZED ESTIMATE FROM DEALER TO REPLACE AND PUT TRUCK BACK TOGETHER IS $4500-$5000. MONEY THAT I DON'T HAVE. THIS IS A POOR DESIGN. DID NOT KNOW/REALIZE THAT A GASKET WOULD FAIL AND ALLOW WATER TO LEAK INSIDE. THE TRUCK IS PARKED IN OUR DRIVEWAY OR ON THE STREET. I DO NOT HAVE A GARAGE. I STARTED TAKING THE SEATS AND CARPET OUT THE LAST WEEK OF DECEMBER 2020. OVER THE NEXT FEW WEEKS INSULATION WAS REMOVED. THE MOLDY/MUSTY SMELL REMAINS. GMC WAS CONTACTED APPROXIMATELY THE LAST OF JANUARY OR THE FIRST WEEK OF FEBRUARY 2021. I AM STILL IN TALKS WITH THEM. AARON, CASE MANAGER AT GMC WITH WHOM I HAVE BEEN DEALING.

2015 GMC SIERRA SLE / 60K MILES / PROJECTOR HEADLIGHTS...NUMEROUS COMPLAINTS FROM NUMEROUS OTHERS, I'M IN THE SAME BOAT. ILLUMINATION IN GENERAL, DRIVING IN RURAL AREAS, DRIVING IN INCLEMENT WEATHER, MAKING TURNS (SIDE STREETS), ETC., IS HORRIBLE, UNSAFE, NERVE-RACKING AND TROUBLESOME. SURE, THE HEADLIGHTS LOOK SNAZZY, BUT PERFORM ABOUT AS WELL AS MY LAWN TRACTOR'S HEADLIGHTS. I SEE THERE'S A TSB REGARDING THE SITUATION AND, MUCH TO MY DISMAY, I HAVE TO PAY FOR SAID PARTS/LABOR TO CORRECT AN OBVIOUS DESIGN FLAW/SNAFU. AM I CRAZY FOR THINKING THIS IS UNACCEPTABLE? EVEN MORE SHOCKING, IT APPEARS THE BCM REPROGRAMMING (MARGINAL RESULTS) AND LAMP REPLACEMENT IS PROBLEMATIC (INCREASED VOLTAGE TO A BULB/LAMP SHORTENS ITS LIFE CONSIDERABLY). A VEHICLE THAT COSTS 30-40-50K SHOULD NOT HAVE GARBAGE TECHNOLOGY. ON THE PLUS SIDE, AT 48 YEARS YOUNG, MY VISION REMAINS 20/20 AND I DO NOT REQUIRE VISION CORRECTION. THE WIFE, MY 2 KIDS (OF DRIVING AGE) AND MY NEIGHBOR CONCUR - THESE HEADLIGHTS SUCK. I LOVE EVERYTHING ELSE ABOUT THE VEHICLE, BUT IT LOOKS LIKE INSTEAD OF SPENDING $200 FOR THE TSB, I'LL TRY MY LUCK WITH AFTERMARKET REPLACEMENTS FOR $300. VIA MULTIPLE ONLINE VEHICLE FORUMS, MOST WHO'VE GONE THE ROUTE OF TSB ARE MARGINALLY IMPRESSED AND EVERYONE ELECTING TO GO WITH AFTERMARKET IS COMPLETELY SATISFIED...THAT ALONE SHINES A SPOTLIGHT ON THE LACK OF VISIBILITY BOTH THE NHTSA AND GM ARE PROVIDING THE CONSUMER. MAYBE INSTEAD OF PAYING SUITS MILLIONS PER YEAR TO PRODUCE SUBPAR VEHICLES, GM SHOULD DO THE RIGHT THING AND FOCUS ON WHAT MATTERS MOST -- THE PAYING CUSTOMER. YEAH, WE HAVE A BETTER SHOT WITH THE NHTSA HOLDING GM ACCOUNTABLE AND FORCE THEM INTO A RECALL (CORRECTING THE PROBLEM PROPERLY, NOT A WILLY NILLY REPROGRAM AND BULB REPLACEMENT).

THE BULBS IN THE TAIL LIGHTS CORRODE IN PLACE DUE TO EXCESS ROAD GRIME (SALT, SAND, ETC.) BEING SPLASHED UP ON THEM. THIS CAUSES THEM TO BURN OUT PREMATURELY AND REMOVAL IS IMPOSSIBLE DUE TO THE CORROSION OF THE BULB INTO THE SOCKET. THIS RESULTS IN HAVING TO REPLACE THE ENTIRE WIRING HARNESS. ACCORDING TO MY LOCAL GMC DEALERSHIP (WEST HERR), THIS IS A COMMON PROBLEM THAT GM ISN'T COVERING. SO, I HAD TO PAY FOR A NEW WIRING HARNESS OUT OF POCKET IN ORDER TO REPLACE ONE OF THE TAIL LIGHT BULBS.
