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.

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.

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.

FAILURE OF THE BELT DRIVEN VACUUM PUMP WHILE DRIVING CAUSING VERY HARD BRAKING AND ALMOST CAUSED AN ACCIDENT. VACUUM PRESSURE DROPPED OFF AND CAUSED THE PEDAL TO BECOME FIRM. LUCKILY AFTER IT WAS INSPECTED FOR REPAIR THERE WASN'T OIL CONTAMINATION IN THE VACUUM LINE OR BRAKE BOOSTER SO THOSE DID NOT HAVE TO BE REPLACED.
Service brakes, Dec 7, 2018
I PULLED INTO A PARKING SPOT AND LOST THE ABILITY TO STOP MY TRUCK. THE BRAKES LOCKED UP AND I COULDN'T PUSH DOWN ON THE BRAKE PEDAL HARD ENOUGH TO GET THE TRUCK TO STOP. I WAS GOING SLOW ENOUGH TO USE THE CURB IN THE SPOT FOR IT TO STOP ME FROM HITTING ANYTHING. I HAD MY CAR TOWED TO A REPAIR SHOP AND THEY CONFIRMED THAT THE BRAKE VACUUM PUMP FAILED AND HAD TO BE REPLACED ALONG WITH THE MASTER CYLINDER AND BECAUSE THE VACUUM PUMP WAS THE INITIAL POINT OF FAILURE, THE REPAIR WAS NOT COVERED UNDER MY WARRANTY.*DT VEHICLE REPAIRED *JB

I FIRST NOTICED THE PROBLEM WHEN I WAS BACKING DOWN THE RAMP TO LAUNCH MY BOAT. GENERALLY I CAN LIGHTLY TOUCH THE BRAKES AND THE TRUCK WILL STOP IMMEDIATELY. BUT THIS TIME IT DID NOT AND I HAD TO PUMP MY BRAKES MULTIPLE TIMES BEFORE IT FINALLY CAME TO A STOP. I WAS QUIT ALARMED BUT KINDA BLEW IT OFF. THE TRUCK HAD TRAVELED ABOUT SIX FEET FURTHER THAN I HAD ANTICIPATED. ABOUT A WEEK LATER I STOPPED TO GO THROUGH MY GATE AT MY FARM AND WHEN I DROVE THROUGH THE GATE WHICH IS ON A SLIGHT HILL DECLINE IT HAPPENED AGAIN. I WENT TO TOUCH THE BRAKES TO STOP AND ENDED UP PUMPING THE BRAKES VIOLENTLY IN ORDER TO GET THE TRUCK TO STOP. THIS TIME I TRAVELED ABOUT SEVEN OR EIGHT FEET BEFORE COMING TO A FULL STOP. AFTER THIS INCIDENT I WAS CONVINCED TO TAKE IT TO THE DEALERSHIP. IT OCCURRED ONCE MORE DURING THAT TIME. THE DEALERSHIP SAID IT WAS A MALFUNCTION IN THE VACUUM PUMP THAT WORKS OFF OF THE MAIN ENGINE AND OIL FROM THE ENGINE HAD CONTAMINATED THE BRAKING SYSTEM. I HAD TO HAVE REPLACED A PUMP, BOOSTER, CYLINDER, PIPE, AND FLUID FOR A TOTAL OF 1266.33 DOLLARS. THAT INVOICE NUMBER IS 208452. I FEEL THIS IS A SERIOUS SAFETY ISSUE WHEN YOU THINK YOUR VEHICLE IS GOING TO STOP AND IT DOES NOT. THIS CAN CAUSE A PANIC SITUATION!

EXPERIENCED AN UNUSUAL REACTION TO BREAKING. A FEW DAYS LATER I HAD BRAKE WARNING LIGHTS ON THE DASH. TOOK THE VEHICLE TO THE DEALER AND THEY HAD TO REPLACE THE CYLINDER BRAKE MASTER AND THE BRAKE BOOSTER AND ADD NEW FLUID. WHICH I PAID FOR. NOW I SEE THERE MAY BE OTHER ISSUES AS THERE ARE OTHER COMPLAINTS YOU'RE INVESTIGATING. I WANT TO PUT MINE ON RECORD.

I BOUGHT THIS TRUCK IN DEC.2017 SENSE MARCH/ APRIL OF 2018 I HAVE EXPERIENCED AT LEAST 8 TIMES MAYBE MORE AND JUST LAST WEEK. THE BRAKE PEDAL HAD LOST IT'S POWER ASSIST. THIS SEEMS TO HAPPEN IN VERY CLOSE SLOW SPEED TRAFFIC OR IN PARKING LOTS WHEN PARKING. THE WAY I SOLVE THIS PROBLEM IS TO PUT TRUCK IN NEUTRAL AND INCREASE RPM'S OR YOU 2 FEET ON THE BRAKE PEDAL ITHE POWER ASSIST WILL SOON RETURN, THESE SITUATION COULD BE A REAL PROBLEM AT HIGHER SPEEDS. I HAVE CHECKED THE VACUUM BOOSTER FOR LEAKS, BRAKE FLUIL AND DONE A FRONT AND REAR BRAKE JOB. THE WEEK OF NOV. 18 I SAW AN ARTICLE IN THE BOSTON GLOBE ABOUT THIS SPECIFIC PROBLEM AND UNDER INVESTIGATION. I CONTACTED MY LOCAL DEALER CENTRAL BUICK AND GMC IN NORWOOD MA..ON NOV 26.2018 THE SERVICE WRITER SAID HE KNEW NOTHING ABOUT THIS PROBLEM OR COMPLAINTS NOR THE ONGOING INVESTIGATIONS. HIS THOUGHT WAS BRING THE TRUCK IN AND WE WILL CHECK AND REPAIR AT MY EXPENSE. SADLY I WISH HIS RESPONSE WAS DIFFERENT . THANKYOU D.S.M.

AT SLOW SPEED BACKING UP OR MOVING FORWARD, I LOSE POWER ASSIST FOR BRAKING, HAVING TO ALMOST STAND ON THE BRAKES TO STOP. THIS HAPPENS INTERMITTENTLY. STREET OR PARKING LOT.
Service brakes, Nov 26, 2018
BRAKES BECOME VERY HARD TO PRESS IN TRAFFIC AND WHILE BACKING UP. THE CONDITION WORSENS WITH MULTIPLE PRESSES OF THE BRAKE PEDAL. THE STOPPING DISTANCE OF THE TRUCK IN INCREASED EVEN WITH INCREASED PRESSURE ON THE PEDAL. THE TRUCK HAS 28,463MI. I CONTACTED A DEALERSHIP AND THEY WILL NOT COVER THIS REPAIR. I HAVE ORDERED THE PARTS AND WILL PERFORM THE REPAIR MYSELF. GM HAS ISSUED A SERVICE BULLETIN ON THIS PIT5361B.

BRAKES APPEAR TO LOSE BOOST WHEN STOPPING. HAVE TO PRESS PEDDLE WITH BOTH FEET. THIS HAS HAPPENED ON THREE SEPARATE OCCASIONS.
Service brakes, Nov 26, 2018
AT SLOW SPEEDS FROM A STOP IF YOU LET OFF THE BREAK PEDAL AND IMMEDIATLY REAPPLY THERE SEEMS TO BE EXTREMELY HARD BREAKING. ALMOST IMPOSSIBLE TO STOP THE CAR.
Service brakes, Nov 26, 2018
ON SEVERAL OCCASIONS THE BRAKE PEDAL BECOMES DIFFICULT TO DEPRESS. RELEASING THE PEDAL AND DEPRESSING AGAIN CORRECTS THE PROBLEM. TODAY WHILE EXITING A PARKING SPACE AT LOW SPEED TO AVOID COLLIDIONG WITH ANN APPROACHING VEHICLE IT TOOK BOTH FEET TO DEPRESS PEDAL. I AM A 200 LB. MALE. I AM NOT SURE A SMALL FEMALE COULD HAVE CORRECTED THE FAILURE IN A TIMELY MANNER.

WHEN I PRESS ON THE BRAKES, IT FEELS AS THOUGH THE MASTER CYLINDER IS GONE AND IT IS THE MANUAL TYPE DRUM BRAKES THAT HAS AIR IN THE LINE. IT TAKES EVERYTHING I HAVE TO PRESS THEM AND PRAY IT STOPS!! THE VEHICLE IS ALWAYS IN MOTION WHEN DETECTING THIS PROBLEM AND SEEMS TO OCCUR MORE REPEATEDLY IF THE BRAKES ARE PUMP QUICKLY IN SUCCESSION BEFORE APPLYING BRAKES OR WHEN THE BRAKES ARE PRESSED FOR AN EXTENDED AMOUNT OF TIME THEN YOU RELEASE AND REPRESS IT WANT STOP. ANOTHER ISSUE IS MY LANE ID WARNING. WHEN TURNED ON AT THE BUTTON, IT JUST BEEPS AT ME AND SHOWS SERVICE LIGHT. WHEN I FIRST TOOK IT IN WITH THE PROBLEM, THE DEALERSHIP CALLED ME AND SAID ALL FIXED, BUT IT DID IT BEFORE I LEFT THE PARKING LOT. THEY HAD MY TRUCK ALL DAY FOR THE ISSUE, PUT ME OUT OF A VEHICLE AND THEN SAID THEY WOULD NEED FOR EXTENDED TIME TO REPAIR BUT DIDN'T KNOW THERE WAS PROBLEM. HOW DO YOU MAKE THAT DETERMINATION WHEN YOU TOLD ME ITS REPAIRED. I JUST TURNED IT OFF AND HAVEN'T USED IN 2 YEARS.

DURING LOW SPEED BRAKING MANEUVERS WHILE PARKING IN MY DRIVEWAY BRAKE PEDAL PRESSURE REQUIRED TO STOP BECAME VERY HARD. IT TOOK BOTH FEET ON THE PEDAL TO ACTUALLY STOP THE TRUCK. THIS WOULD HAPPEN DAILY WHILE BACKING IN TO MY DRIVEWAY. ALSO DURING NORMAL CITY STOP AND GO DRIVING IT WOULD ALSO REQUIRE GREAT EFFORT TO STOP THE TRUCK AND THE PEDAL WOULD BE VERY HARD TO PRESS.

VEHICLE LOSES BRAKE PRESSURE WHILE MOVING AT SLOWER SPEEDS. ONCE COMING TO A STOP, THEN DOING SLOW SPEED STOPS AND STARTS THE PEDAL WILL BECOME HARD AND REQUIRES GREAT EFFORT TO BRING THE VEHICLE TO A COMPLETE STOP. ISSUE STARTED AT ABOUT 38,000 MILES JUST AFTER FACTORY 36,000 MILE WARRANTY. ISSUE PRESENTS ITSELF MORE OFTEN IN REVERSE WHILE BACKING IN, ESPECIALLY IF GRADE IS SLOPED. HAVE HAD MULTIPLE CLOSE CALLS IN PARKING LOT SETTINGS WHILE TRYING TO BACK IN TO A PARKING SPOT OR INCH FORWARD. A FRIEND HAD THIS SAME ISSUE WITH HIS 2016 CHEVROLET SILVERADO, WHICH ENDED UP BEING A $1,800 FIX THROUGH THE DEALERSHIP.
