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. This recall supersedes NHTSA recall number 20V-736. GM's number for this recall is N202324251.

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.

If the end cap separates from the inflator, the compressed gas will escape and the end cap can be propelled into the vehicle, increasing the risk of injury or a crash.
GM will notify owners, and dealers will replace the RRAB modules on the left and/or right side, free of charge. Interim owner notification letters were mailed on December 22, 2020.

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.
GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began October 8, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192268490.

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.
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.

at first my brakes began locking up on the vehicle, almost as if they were pumped full and not able to press down any longer, shortly after that the stabilitrack light came on and white smoke began to come out of the exhaust as well as a slight shake in the engine, i immediately turned the vehicle off and parked it, mind you i bought the vehicle 1 day ago and it is already broke down, the issue is with gmc and these sensors they are using they are faulty engine reduces speed and it is not safe to say the least.not only that but had the exact same problems with my Gmc Acadia which i finally got the light to stop going off after replacing transmission, brake pedal position censor, as well as gas pedal position censor, also had the throttle body replaced, Do you all make products that are worth anything, nothing was ever done about the Acadia, the Gmc sierra is a 2015 with 70,000 miles on it this car should not be acting like this please contact me at [XXX] thank you so much for your time, also there are 14 recalls on this year truck yet mine shows that there are 0 recalls to be fixed I am wondering about this as well.

I bought my 2015 gmc sierra 1500 certified and since then it has had vibrations when driving and hard shifts. The dealer has looked it over many times and said it's normal. Last month they said they sent gmc the readings and I haven't heard back. They have lied to me before about other vehicles and I'm tired of dealing with them not fixing it.

While operation my 2015 GMC 1500 DENALI Pickup at normal conditions my vehicle produced a engine light. I was three blocks from my office so I proceeded there immediately to have my vehicle scanned for codes. This is where I found out that cylinder #7 had an issue. This cylinder is part of the AFM system. I had the vehicle towed to Galles Chevrolet for diagnostic services and an estimate for repairs. Up receiving the results (which) I will attach. Bank 1 and possibly Bank 2 lifters and springs have failed. Thus possibly cause damage to the cam shaft. While I am aware that my vehicle is out of powertrain warranty (5 years / 100,000 mile), my vehicle only has 52,000 miles on it and very very well taken care of at all times. I am also aware of a class action law suite that pertained to the same exact issue on gm products from 2004-2014. Also service bulletins were produced by GM pertaining to this issue. Now I have been out of service of my vehicle for 3 1/2 weeks not to mention a potential $7000 repair, that should have never been in the picture! Poor quality control on products for potential profit gains have cost many many customers pain, anguish, and money.

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.

MY 2015 GMC SIERRA HAS THE 8 SPEED TRANSMISSION WHICH HAS BEEN AN ISSUE SINCE I HAVE OWNED THE VEHICLE. I BOUGHT THE VEHICLE USED IN THE FALL OF 2018 AND THE TRUCK/TRANNY RAN GOOD FOR ABOUT 10 MONTHS. THEN IN LATE SUMMER AND EARLY FALL OF 2019, THE TRUCK JERKING HARD SHIFTS STARTED TO APPEAR. IN OCTOBER OF 2019 I BROUGHT MY TRUCK INTO MY DEALER TO HAVE THEM LOOK AT MY TRANNY DUE TO THE REALLY HARD SHIFTS FROM 1ST TO 2ND OR 2ND TO 3RD AND VICE VERSA 3RD TO 2ND AND 2ND TO 1ST. I HAD TO PAY A $80 DIAGNOSIS FEE AND THEY REPROGRAMMED MY TRANNY AND THE ECU TO SMOOTH OUT THE SHIFTS AND NOT MAKE THE SHIFTS SO HARD. IN ALL THE SOFTWARE REPROGRAM DID GET RID OF THE HARD SHIFTS, BUT IN RETURN NOW MY VEHICLE DROVE LIKE IT HAS A 6 SPEED TRANSMISSION INSTEAD OF AN 8 SPEED. IN JUNE OF 2020 I BROUGHT MY TRUCK BACK INTO MY DEALER TO LOOK AT MY TRANNY AGAIN! NOW MY TRANNY FELT LIKE IT WAS ALWAYS "HUNTING" FOR A DIFFERENT GEAR. WHEN DRIVING ON THE INTERSTATE AT 75 MPH 1600 RPM, IF THERE WAS A LITTLE BIT OF HEAD WIND OR I STARTED TO DRIVE UP A HILL, THE TRANNY WOULD DOWNSHIFT AND RPM'S JUMP UP TO 2200 RPM TO MAKE UP FOR THE DIFFERENCE IN ROAD GRADE, SAME AS WHEN DRIVING IN TOWN UP A HILLAT 35MPH. A 8 SPEED TRANSMISSION SHOULD NOT BE DOING THAT! AT INTERSTATE SPEEDS (75 MPH) MY PASSENGER SIDE SEAT WILL SIT THERE AND JUST WIGGLE AND SHAKE BACK AND FORTH. I HAVE CHANGED OUT BALL JOINTS AND STRUTS WITH BRAND NEW ONES THINKING THAT WAS THE PROBLEM AND THE SEAT STILL WIGGLES BACK AND FORTH. WHEN DRIVING MY VEHICLE IT FEELS LIKE I AM DRIVING WITH A 6 SPEED TRANSMISSION THAN AN 8 SPEED. I HAVE READ THAT THIS SEEMS TO BE A COMMON PROBLEM IN THESE MODEL YEAR GM VEHICLES AND I FEEL GM NEEDS TO FINALLY ADDRESS THIS ISSUE ONCE AND FOR ALL AND KEEP THEIR GM CUSTOMERS SATISFIED. I DIDN'T PLAN ON BUYING A 3 YEAR OLD USED VEHICLE FOR IT TO HAVE THE ISSUES IT HAS HAD SINCE I HAVE OWNED IT. *TR
