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.

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.

General Motors LLC (GM) is recalling certain model year 2014-2016 Buick Lacrosse and Chevrolet Spark EV, Caprice PPV and SS vehicles, 2014-2017 Buick Encore and Chevrolet Corvette, Silverado 1500 and GMC Sierra 1500 vehicles, 2015-2016 Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Trax, Suburban and Silverado 2500 and 3500 and GMC Yukon and Yukon XL vehicles, and 2015-2017 GMC Sierra HD 2500 and 3500 vehicles. 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. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782.

MY TRUCK SUFFERS FROM VIBRATION PROBLEMS, THE SAME THING THAT 10,837 OTHER POSTS FROM OTHER PEOPLE SUFFERING THE SAME PROBLEM ARE TALKING ABOUT ON THIS FORUM. HTTP://WWW.GM-TRUCKS.COM/FORUMS/TOPIC/153186-SHAKE-OR-VIBRATION-ISSUES/PAGE-723 THIS FORUM HAS BEEN VIEWED OVER 1.5 MILLION TIMES WHICH MEANS A TON OF PEOPLE ARE HAVING THIS ISSUE. THIS IS ABSOLUTELY A RISK TO MOTOR VECHICLE SAFETY AND ABSOLUTELY EXISTS IN A GROUP OF VECHICLES OF THE SAME DESIGN OR MANUFACTURE. THE PROBLEMS THIS SHAKE PRESENTS THAT POSE A DANGER ARE VIBRATIONS SO SIGNIFICANT THAT IT CAN CAUSE DRIVER DISTRACTION, FATIGUE ON LONG TRIPS, POTENTIAL LOSS OF CONTROL, NOT TO MENTION LONG TERM HEALTH EFFECTS FROM VIBRATION EXPOSURE. THE HEALTH EFFECTS DEFINED ARE AS FOLLOWS: "THE EFFECTS OF WHOLE BODY VIBRATION (WBV) HAVE BEEN STUDIED EXTENSIVELY IN OCCUPATIONAL MEDICINE. IN PARTICULAR, IT HAS BEEN SHOWN THAT WHEN THE BODY UNDERGOES CHRONICALLY TO WHOLE BODY VIBRATIONS SPINAL DEGENERATION IS LIKELY TO BE ONE OF THE DELETERIOUS OUTCOMES. LOW BACK PAIN HAS BEEN SHOWN TO BE THE LEADING MAJOR CAUSE OF INDUSTRIAL DISABILITY IN THE POPULATION UNDER THE AGE OF 45 YEARS AND HAS BEEN LINKED TO WHOLE BODY VIBRATION EXPOSURE ENCOUNTERED IN SOME INDUSTRIAL SETTINGS. WHOLE BODY VIBRATION HAS BEEN RECENTLY PURPOSED AS AN EXERCISE INTERVENTION SUGGESTING ITS EFFECTIVENESS IN INCREASING FORCE-GENERATING CAPACITY IN LOWER LIMBS AND LOW BACK. IT HAS ALSO BEEN REPORTED TO BE AN EFFECTIVE NON-PHARMACOLOGICAL INTERVENTION FOR PATIENTS WITH LOW BACK PAIN. RELATIVELY SHORT EXPOSURE TO WHOLE BODY VIBRATION HAS BEEN ALSO SHOWN TO INCREASE THE SERUM LEVELS OF TESTOSTERONE AND GROWTH HORMONE. THE COMBINED EFFECTS ON THE NEUROMUSCULAR SYSTEM AND ENDOCRINE SYSTEM SEEM TO SUGGEST ITS EFFECTIVENESS AS A THERAPEUTIC APPROACH FOR SARCOPENIA AND POSSIBLY OSTEOPOROSIS."

I BOUGHT THE VEHICLE NEW IN 9/2015. I REPORTED A VIBRATION BETWEEN 75-80MPH TO THE NEARBY GM DEALER (TWICE). THE DEALER KEPT THE TRUCK FOR A FEW DAYS AND STATED THEY COULD NOT CORRECT THE PROBLEM. I TOOK THE TRUCK BACK TO THE ORIGINAL DEALER WHERE I BOUGHT IT, THEY DID A ROAD FORCE BALANCE ON THE TIRES AND REPORTED THE PROBLEM FIXED. I TOOK THE TRUCK BACK TO THE ORIGINAL DEALER AT 13K MILES, THEY KEPT THE TRUCK FOR A FEW DAYS AND REPORTED THE TIRES NEEDED TO BE REPLACED. THEY REPLACED THE TIRES AND STATED THE VIBRATION HAS BEEN RESOLVED. I DROVE THE TRUCK FOR ANOTHER 3K MILES AND NOTICED THAT THE VIBRATION WAS STARTING UP AGAIN.

I PURCHASED MY FIRST NEW VEHICLE IN OCT OF 2015. I'VE OWNED 4 VEHICLES SINCE I'VE HAD MY LICENSE, 2 DODGES AND 2 BMWS. I CHOSE A TRUCK I'VE DREAMED OF HAVING SINCE I WAS 16. I'M CURRENTLY 28. I CHOSE THE SIERRA DENALI. NOT ONLY WAS THIS MY FIRST NEW VEHICLE BUT THIS WAS MY FIRST TRUCK AND MY FIRST GM PRODUCT OF MY LIFE. NOW I'M TEETERING ON IT BEING MY LAST. THROUGH THE 14 MONTHS I'VE OWNED THE VEHICLE (SINCE 4 MILES) I'VE HAD NUMEROUS ISSUES. MY FRONT DIFFERENTIAL HAS BEEN REBUILT NOT ONCE BUT TWICE. MY TRUCK HAS 45K ON IT. IT HAS NEVER TOWED HAULED OR OTHER WISE PERFORMED A TASK REQUIRING IT'S POWER OTHER THAN NORMAL DRIVING. IT HAS BEEN BABIED. CLEANED WASHED OIL CHANGED TIRES ROTATED AND 93 OCTANE FILL UPS. AMONGST OTHER ISSUES WERE THE INFOTAINMENT CENTER FREEZING. CVS AXLE SHAFTS PERFORMING ERRATIC ALONG WITH BUCKING SLAMMING AND NOISES THROUGH THE POWER TRAIN. A RANDOM LEAK IN THE LOWER OIL PAN THAT THE DEALER SAID WAS A MANUFACTURER DEFECT THEY WERE AWARE OF. A AIRBAG SOFTWARE SAFETY RECALL AND A SHIFTING DRIVER SEAT THAT TENDS TO MOVE A BIT DURING CORNERING. NOW TO TOP ALL OF THOSE ISSUES OFF IN THOSE 14 MONTHS I NOW HAVE A LEAK THE EXTENDS OUT FROM THE EDGE ABOUT 5 INCHES FROM THE REAR WINDSHIELD ALL THE WAY FROM THE DRIVER SIDE TO PASSENGER SIDE. I'M NOT IN BUMPER TO BUMPER WARRANTY. I WAS TOLD 100 DOLLARS AND IT WILL BE FIXED. IT SHOULDN'T HAVE TO BE FIXED. NONE OF IT SHOULD HAVE. I HAVE HAD LESS ISSUES IN ALL 4 OF MY LAST VEHICLES PUT TOGETHER THAN THIS 1 VEHICLE I HAVE OWNED FOR 14 MONTHS AND I BOUGHT IT NEW. THIS HAS BEEN A BIG LET DOWN.
