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.
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.

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

WHILE THE HEAD LIGHTS AND FOG LIGHTS ARE ON, THE RIGHT HEAD AND FOG LIGHTS ARE DIM BUT THE LEFT HEAD AND FOG LIGHTS ARE BRIGHT. ALSO THE RIGHT TURN SIGNAL SHOWS ERROR MESSAGE ON THE CLUSTER THAT THE BULB NEEDS TO BE REPLACED AND YOU CAN HEAR IT BLINKING FAST, BUT WHEN I EXIT THE VEHICLE TO INSPECT THE SIGNAL I NOTICE THAT IT IS NOT BLOWN AND IT WORKS FINE BUT I STILL GET THE ERROR MESSAGE AND THE FAST BLINKING. BOTH STATED PROBLEMS OCCUR WHILE THE VEHICLE IS STATIONARY AND WHEN THE VEHICLE IS IN MOTION. *TR

BRAKING ISSUE. WHILE TRAVELING IN A DRIVE THRU, VEHICLE BRAKE PEDAL WENT TO THE FLOOR, PULSATED SOME, AND REQUIRED EXTREME EFFORT TO STOP. THIS OCCURRED DURING SUBSEQUENT BRAKING INCIDENTS WHILE MOVING AND STOPPING IN THE DRIVE-THRU. AFTER LEAVING, BRAKE PEDAL FELT OK. GOOGLED SYMPTOMS WHICH MATCHED MY CIRCUMSTANCES AND LISTED A RECALL. HOWEVER, THERE IS NO RECALL LISTED ON NHTSA. SEEMS A LITTLE TROUBLING AS THIS APPEARS TO AFFECT 3.4 MILLION GM VEHICLES. *TR

PICKUP HAS HAD REOCCURRING SERVICE POWER STEERING MESSAGE COME UP IN INFORMATION CENTER. TOOK TO GM AND THEY SAID IT NEEDED A NEW NEGATIVE BATTERY CABLE. BOUGHT ONE AND INSTALLED IT. STILL HAVE THE SAME PROBLEM. UPON DONG SOME SEARCHING, ITS A VERY COMMON PROBLEM AMONG CERTAIN GM VEHICLES. ONE WEEKEND THE POWER STEERING QUIT WORKING ALL TOGETHER AT 70 MPH ON A CURVE. TALK ABOUT SCARY! I CALLED GM CUSTOMER SERVICE TO ASK ABOUT COVERAGE ON THE ISSUE AND WAS DENIED BECAUSE MY VEHICLE WAS NOT ONE AFFECTED BY THE SUSPECT FAULTY PARTS. I AM VERY DISAPPOINTED IN GM'S LACK OF CARING FOR MY SAFETY IN THIS SITUATION. WILL NOT BE PURCHASING ANOTHER GM. IF THEY NO THAT THIS IS THEIR PROBLEM I TRULY BELIEVE THEY SHOULD STAND BEHIND THEIR PRODUCT AND TAKE CARE OF THEIR CUSTOMERS.

HAVE HAD MY VEHICLE AT THE SHOP FOR TRANSMISSION ISSUES SEVERAL TIMES. TWO OF THE TIMES, ISSUES WERE DUPLICATED AND PARTS REPLACED, BUT SAME ISSUES CONTINUE AS SOON AS I GET IT BACK. MY COMPLAINT WHEN I TAKE IT IN IS ALWAYS THE SAME. NORMALLY WHEN I ACCELERATE FROM A DEAD STOP FORWARD OR REVERSE, THE TRANSMISSION MAKES A THUMPING NOISE. IT HAS STEADILY GOTTEN WORSE. A LOT OF TIMES NOW IF I TAKE MY FOOT OFF GAS FOR A SECOND, AT FASTER SPEEDS, AND THEN PUT FOOT RIGHT BACK ON GAS, IT MAKES THE SAME THUMPING NOISE AND SOMETIMES A GRINDING NOISE LIKE IT'S STUCK BETWEEN GEARS. THIS LAST TIME I TOOK IT TO THE DEALER, WAS TOLD THERE WAS NOTHING THEY COULD DO AND WOULD MOST LIKELY GET WORSE AS VEHICLE GETS OLDER.
